Doctor's Best High Absorption Magnesium Lysinate Glycinate (Albion TRAACS, 100mg per tablet)Review 2026
Doctor's Best High Absorption Magnesium scores 81/100. Value-tier BUY: 100mg Albion TRAACS lysinate glycinate per tablet, $0.28 CPED, lowest in category.
EDE Score
Verdict
Cost per effective day
$0.28 / effective day/ day
Why this verdict
- Albion TRAACS chelated form, original patented high-absorption magnesium technology
- Lowest CPED in magnesium category at $0.28 per effective day
- 60 days of clinical 400mg dosing per single 240-tablet bottle
Verdict: BUY (value-tier). EDE Score 81/100. Doctor's Best High Absorption Magnesium is the value-tier anchor of the magnesium category: Albion TRAACS chelated lysinate glycinate, brand-recommended 4-tablet daily regimen reaches the full 400 mg clinical dose, and CPED of $0.28 per effective day is the lowest in our entire magnesium catalog. Trade-offs versus higher-scoring alternatives are tablet form rather than capsule (slight bioavailability handicap), no NSF Sport or USP certification, and mid-tier (not practitioner-grade) brand reputation. For buyers who do not need NSF Sport credentials and want the cheapest defensible magnesium glycinate at clinical dose, this is the right buy.

Why this product matters for men 40+
Magnesium deficiency is the single most under-diagnosed and under-treated mineral status problem in adult American men. NHANES dietary intake data shows roughly 50-60% of US adults consume below the Estimated Average Requirement (350 mg/day for men 31-70).1 Doctor's Best's own marketing cites a higher figure (75% of Americans deficient), and while that number is debated in the literature, the underlying truth is settled: most adult men eating standard American diets do not get enough magnesium from food alone.
For men 40 and older, the consequences of suboptimal magnesium status compound over years: reduced testosterone production, poorer sleep architecture, slower exercise recovery, elevated blood pressure, increased insulin resistance, elevated risk of cardiac arrhythmias and atrial fibrillation, and accelerated bone loss. The mechanistic chain is well documented: magnesium is required as a cofactor in over 600 enzymatic reactions including ATP synthesis, DNA replication, protein synthesis, glucose metabolism, and neurotransmitter regulation.2
The clinical effective dose for adult men, per NIH Office of Dietary Supplements and per the cluster of randomized controlled trials in the magnesium literature, sits between 300 and 400 mg of elemental magnesium daily. The recommended dietary allowance is 420 mg for men 31 and older. Most clinical trials testing functional outcomes in men (testosterone, sleep, blood pressure, glucose handling, strength) use doses in the 300-450 mg range.
This is the dose target Doctor's Best High Absorption Magnesium hits exactly when taken at the brand-recommended regimen of 2 tablets twice daily (4 tablets total = 400 mg elemental). Unlike products that label a single-serving sub-clinical dose and rely on the buyer to scale up, Doctor's Best's labeled regimen IS the clinical full dose. This is rare in the magnesium market.
Editorial commentary
Doctor's Best is one of the longest-running specialty supplement brands in the US, founded in 1990 by a physician with a stated focus on science-based formulations. The brand has built its reputation on partnerships with patented ingredient suppliers (Balchem's Albion division for chelated minerals, AjiPure amino acids, and others) rather than on practitioner-grade institutional credibility (the Thorne, Pure Encapsulations, Designs for Health tier).
This product specifically uses Albion TRAACS magnesium lysinate glycinate, which is the original patented chelated magnesium technology. TRAACS stands for "The Real Amino Acid Chelate System". The chelation binds elemental magnesium to two amino acid ligands (glycine and lysine), creating a stable molecule that bypasses the saturable inorganic magnesium transporter and is absorbed via dipeptide-style transport in the intestine. This is functionally equivalent to bisglycinate chelation, which is also an Albion technology in many products on the market. The lysinate-glycinate combination is the older, OG patented form.
Two structural features distinguish this product from the rest of the magnesium category:
The first is tablet form. Doctor's Best uses compressed tablets with standard pharmaceutical excipients (microcrystalline cellulose, croscarmellose sodium, stearic acid, hypromellose coating). Tablets typically have slightly slower disintegration profiles than capsules and require more aggressive binding to hold form. User reviews on iHerb and Amazon repeatedly note that the powder version of Doctor's Best magnesium "works better than the pills", which we interpret as a real-world bioavailability gap between the two delivery formats. The chelate itself is excellent; the tablet delivery is functional but not optimal.
The second is price positioning. At $16.99 for 240 tablets at 100 mg per tablet, the bottle delivers 60 days of clinical dosing at the brand-recommended 4-tablet daily regimen. CPED works out to $0.28 per effective day, which is the lowest in our entire magnesium catalog. Pure Encapsulations Magnesium Glycinate runs $0.78 per effective day. Klean Athlete Klean Magnesium runs $0.88 per effective day. Thorne Magnesium Bisglycinate runs $1.25 per effective day. Doctor's Best is materially cheaper than all three.
The premium that Pure Encapsulations charges over Doctor's Best ($0.78 vs $0.28, approximately 180% higher) buys you practitioner-grade brand reputation and capsule form. The premium that Klean Athlete charges ($0.88 vs $0.28, approximately 215% higher) buys you NSF Certified for Sport credentials and capsule form. Whether either premium is worth it depends on whether you need those features. For drug-tested athletes the NSF Sport premium is rational. For buyers prioritizing clinical dose at lowest cost without certification requirements, Doctor's Best is the right pick.
This review consolidates the four-product magnesium triangle now in our catalog:
- Thorne Magnesium Bisglycinate (BUY 88, CPED $1.25): Powder, 200 mg per single scoop, no NSF Sport, premium brand.
- Klean Athlete Klean Magnesium (BUY 87, CPED $0.88): Capsule, 120 mg per cap, NSF Certified for Sport, athlete-tier.
- Pure Encapsulations Magnesium Glycinate (BUY 84, CPED $0.78): Capsule, 120 mg per cap, no NSF Sport, practitioner-grade brand.
- Doctor's Best High Absorption Magnesium (BUY 81, CPED $0.28): Tablet, 100 mg per tab, no NSF Sport, value-tier brand.
The score difference between Doctor's Best (81) and Pure Encapsulations (84) is approximately 3 points, driven primarily by manufacturer reputation tier and form factor. The CPED gap ($0.28 vs $0.78) is far larger than the score gap. For most general buyers, Doctor's Best is the rational default unless practitioner-grade brand affinity matters specifically.
What is actually in it
| Ingredient | Form | Dose per tablet | Dose per serving (2 tablets) | Dose at full regimen (4 tablets) | Clinical effective dose | Evidence level |
|---|---|---|---|---|---|---|
| Magnesium | Lysinate glycinate chelate (Albion TRAACS) | 100 mg elemental | 200 mg elemental | 400 mg elemental | 300-400 mg/day | strong |
Other ingredients (inactives): Microcrystalline cellulose (binder/filler), croscarmellose sodium (disintegrant), magnesium stearate from vegetable source (lubricant), stearic acid (lubricant), hydroxypropyl cellulose (binder/coating), silicon dioxide (anti-caking), hypromellose (coating).
The active ingredient is elemental magnesium chelated with the amino acids glycine and lysine in the patented Albion TRAACS form. Unlike pure magnesium glycinate (which uses two glycine ligands per Mg atom), magnesium lysinate glycinate chelate uses a glycine + lysine ligand pair. The two forms are clinically equivalent in absorption studies. Both are categorized as "chelated magnesium" and both bypass the saturable inorganic Mg transport mechanism in the gut.
The inactive ingredients list is longer than capsule-format competitors (Pure Encapsulations and Klean Athlete each have 2 inactives; Doctor's Best has 7) because tablet manufacturing requires binders, disintegrants, lubricants, and coating agents that capsule manufacturing does not. None of these inactives is problematic; all are standard pharmaceutical-grade excipients. The longer list reflects the form choice, not formulation quality issues.

Notes on each criterion:
Dose Efficacy (85): Per-serving (2 tablets) delivers 200 mg = 50% of clinical 400 mg. Brand-recommended regimen (4 tablets daily) delivers exactly the clinical full dose of 400 mg. Better per-serving percentage than Klean Athlete (50% vs 30%) and brand-labeled regimen aligns with clinical target. Score reflects the labeled regimen reaching exact clinical dose.
Bioavailability (88): Albion TRAACS lysinate glycinate chelate is functionally equivalent to magnesium bisglycinate (top-tier form per methodology rubric, scored 92). Tablet delivery vs capsule introduces a small handicap due to compression-related disintegration profile and binder excipients. Net score 88, slightly below pure capsule glycinate but well above oxide, citrate, or malate forms.
Third-Party Testing (50): No NSF Certified for Sport, no USP Verified, no Informed Sport. Albion TRAACS technology provides Balchem-certified raw material chelation (third-party verified at the ingredient level), and the brand claims "rigorously tested" without disclosure of public batch CoA. Mid-tier between "claims third-party tested without disclosure" (30) and "publishes CoA per batch" (75).
Label Transparency (100): Single active ingredient, exact mg disclosed. No proprietary blend. All seven inactive ingredients disclosed.
Manufacturer Reputation (80): Doctor's Best, founded 1990 by a physician, 35+ year operating history. No major FDA recalls or warning letters in the past decade. Mainstream reputable mid-tier brand. Below practitioner-grade incumbents (Thorne, Pure Encapsulations, Designs for Health, Douglas Laboratories at 92-95 tier) but well above value brands with thinner manufacturing track records.
Community Sentiment (50): Phase 1 default. Reddit Intelligence layer arrives Q3 2026.
Price Per Effective Dose (100): CPED $0.28 = below $0.50 threshold = max score. Lowest CPED in the magnesium category and among the lowest in the entire DosedWise catalog. Tied with Momentous Vitamin D3 5000 IU NSF Sport at $0.28.
What we like
- Albion TRAACS chelated lysinate glycinate is the original patented high-absorption magnesium technology. Functionally equivalent to bisglycinate. Top-tier form that bypasses the saturable inorganic Mg transporter and minimizes GI side effects.
- Brand-recommended regimen (2 tablets twice daily, 4 tablets total) delivers exactly 400 mg elemental magnesium = clinical full dose. No per-serving sub-clinical labeling trick.
- 240-tablet bottle = 60 days of clinical dosing at the recommended regimen. Longest day-supply per bottle of any magnesium product in the DosedWise catalog.
- CPED of $0.28 per effective day is the lowest in the magnesium category. Materially cheaper than Pure Encapsulations ($0.78), Klean Athlete ($0.88), and Thorne ($1.25).
- Vegan, non-GMO, gluten-free, soy-free. Inactive ingredients are all standard pharmaceutical-grade excipients.
- Single active ingredient, exact mg disclosed. No proprietary blend, no oxide-glycinate hybrid masking.
- Wide retail availability: brand-direct, Amazon, iHerb, Vitacost, Vitamin Shoppe, Walmart, Target, Swanson Vitamins. Authentic supply chain across multiple channels.
- Manufacturer track record is clean: no FDA recalls, no warning letters, 35+ year operating history.
What we don't like
- Tablet form rather than capsule. Tablets have slower disintegration and higher binder content than capsules. User reviews on iHerb and Amazon repeatedly note that the powder version "works better than the pills", which we interpret as real-world bioavailability gap between formats.
- Tablets are physically large. Multiple user reviews flag the size as difficult to swallow. The 4-tablet daily regimen multiplies this friction. Buyers with pill-swallowing difficulty should consider the capsule or powder versions of Doctor's Best magnesium instead.
- No NSF Sport, no USP, no Informed Sport certification. Drug-tested athletes cannot use this product. Klean Athlete Klean Magnesium (BUY 87) is the right pick for that audience.
- Mid-tier brand reputation (80) versus practitioner-grade peers (Thorne, Pure Encapsulations, Douglas Laboratories at 92-95). The brand has a clean operating record, but it does not carry the institutional credibility of practitioner-grade incumbents.
- Albion TRAACS is third-party verified at the raw material level via Balchem certification, but the finished product does not carry independent batch certification. "Rigorously tested" claim is unverified.
- 7 inactive ingredients (vs 2 in Klean Athlete and Pure Encapsulations) reflect the tablet form requirements. Not problematic but worth noting for buyers preferring minimalist excipient lists.
- Daily 4-tablet regimen is logistically more intrusive than single-cap or single-scoop alternatives. Splitting 2 tablets twice daily is the most effective protocol but also requires planning.
Cost per effective day (CPED)
Bottle price (retail): $16.99
Tablets per bottle: 240
Per-tablet elemental magnesium: 100 mg
Brand-recommended daily regimen: 4 tablets (2 twice daily)
Daily elemental magnesium delivered: 400 mg = clinical full dose
Days of effective dosing per bottle: 240 / 4 = 60 days
CPED: $16.99 / 60 = $0.2832 per effective day
Doctor's Best High Absorption Magnesium costs $0.28 per effective day at the brand-recommended 4-tablet regimen.
This is the lowest CPED in our entire magnesium category and tied for the lowest CPED in the entire DosedWise catalog (tied with Momentous Vitamin D3 5000 IU NSF Sport at $0.28).
For comparison within the magnesium category:
| Product | Form | Per-serving Mg | Brand-rec daily | CPED | EDE Score | Verdict |
|---|---|---|---|---|---|---|
| Doctor's Best High Absorption Mg | Tablet | 200 mg (2 tabs) | 400 mg (4 tabs) | $0.28 | 81 | BUY (value-tier) |
| Pure Encapsulations Magnesium Glycinate | Capsule | 120 mg (1 cap) | 360 mg (3 caps) | $0.78 | 84 | BUY |
| Klean Athlete Klean Magnesium | Capsule | 120 mg (1 cap) | 360 mg (3 caps) | $0.88 | 87 | BUY (athlete-tier) |
| Thorne Magnesium Bisglycinate | Powder | 200 mg (1 scoop) | 200-400 mg | $1.25 | 88 | BUY |
The CPED structural advantage of Doctor's Best is real and material. At $0.28 per day versus $0.78-1.25 across competitors, the annual cost difference at clinical dose is approximately $180-355 per year. For most buyers without specific brand or certification requirements, this is a meaningful saving.
Ingredient-by-ingredient analysis
Magnesium (as Albion TRAACS Lysinate Glycinate Chelate)
Dose in this product: 100 mg elemental magnesium per tablet, 400 mg per recommended 4-tablet daily regimen Clinical effective dose: 300-400 mg/day (NIH ODS, multiple RCT clusters) Evidence level: Strong Verdict for this ingredient: Brand-recommended regimen exactly matches clinical full dose
Magnesium is involved in over 600 enzymatic reactions in the human body, making it one of the most consequential dietary minerals for adult health. For men 40+, the most clinically relevant magnesium-related outcomes include:
- Testosterone production: Cinar 2011 showed that 4 weeks of 10 mg/kg/day magnesium supplementation in 30 men increased total and free testosterone in both sedentary and trained groups, with the effect more pronounced in active training subjects.3
- Sleep architecture: Multiple RCTs have shown improvements in sleep latency, sleep efficiency, and subjective sleep quality with 320-500 mg magnesium supplementation, particularly in older adults and in subjects with insomnia.4
- Skeletal muscle strength: Brilla and Haley 1992 and follow-up replications have shown magnesium supplementation improves strength gains during resistance training programs in deficient or marginal subjects.5
- Blood pressure: A 2012 meta-analysis of 22 RCTs (n = 1173) showed mean systolic blood pressure reduction of 3-4 mmHg with magnesium supplementation, with stronger effects at higher doses (above 370 mg/day).6
The form Doctor's Best uses (Albion TRAACS magnesium lysinate glycinate chelate) is functionally equivalent to magnesium bisglycinate. Both are top-tier chelated forms with absorption rates of approximately 90% versus 4% for magnesium oxide.7 The Albion technology has the longest commercial track record of any chelated mineral system (Albion was founded 1956 and pioneered the original TRAACS chelation patent). Balchem Corporation acquired Albion in 2013 and continues to operate the TRAACS production system from Albion's Utah facility.
The chelation accomplishes three things:
- High absorption via dipeptide-style intestinal uptake bypassing the saturable inorganic magnesium transporter.
- No laxative effect because chelated forms do not draw osmotic water into the intestinal lumen the way oxide, sulfate, and citrate do.
- Amino acid co-delivery (glycine and lysine), which adds modest physiological value (glycine for collagen synthesis and mild GABAergic effect; lysine for gastric function and protein synthesis).
The tablet delivery format is the qualifier on this otherwise excellent active ingredient. Tablet disintegration in the stomach is slower than capsule dissolution, and the seven excipients required for tablet manufacturing (versus two for capsules) introduce additional variables. User-reported experience with this product split: many describe excellent results on sleep, muscle relaxation, and recovery; a meaningful minority describe minimal subjective effect and prefer the powder version. This pattern suggests genuine bioavailability variance, not placebo.
Take across two to three daily doses (2 tablets in morning and 2 in evening, or 1 tablet four times across the day) rather than all 4 at once. Schedule the largest single dose in the evening for sleep-supportive effect.
Community sentiment summary
Phase 1 default sentiment score: 50/100.
DosedWise will publish aggregated Reddit sentiment for Doctor's Best High Absorption Magnesium across r/Testosterone, r/TRT, r/PeterAttia, r/Supplements, and r/Nootropics in Q3 2026 when our Reddit Intelligence layer ships. Until then, this criterion uses a neutral default and represents 5% of the total EDE Score.
Anecdotal user feedback on iHerb and Amazon reviews skews positive on price-to-quality ratio and on the chelated form's gut tolerance. The most common consistent critique is tablet size and the comparison-to-powder bioavailability gap. Many users specifically recommend the powder version of Doctor's Best Mg over the tablets if absorption is the priority.
[Note: Community sentiment is one signal among seven and is weighted 5% in the EDE Score. See methodology.]
Compared to alternatives
For magnesium supplementation, here is how Doctor's Best High Absorption Magnesium compares to other entries in our catalog:
| Product | EDE Score | CPED | Verdict | Key differentiator |
|---|---|---|---|---|
| Thorne Magnesium Bisglycinate | 88/100 | $1.25 | BUY | Powder, 200 mg per scoop, single-serving clinical |
| Klean Athlete Klean Magnesium | 87/100 | $0.88 | BUY (athlete-tier) | NSF Certified for Sport, capsule, 120 mg per cap |
| Pure Encapsulations Magnesium Glycinate | 84/100 | $0.78 | BUY | Practitioner-grade, capsule, 120 mg per cap |
| Doctor's Best High Absorption Magnesium | 81/100 | $0.28 | BUY (value-tier) | Albion TRAACS, tablet, lowest CPED in category |
The score-to-cost ratio at the value tier is striking. Doctor's Best scores 7 points lower than Thorne (81 vs 88) but costs roughly 22% as much per effective day ($0.28 vs $1.25). For 90% of buyers without a specific institutional or athletic certification requirement, the value math favors Doctor's Best.
The category does not yet have a TOP PICK because no current entry combines optimal form (chelated glycinate or threonate), single-cap clinical dose (200+ mg per cap), and gold-standard certification (NSF Sport or USP). A hypothetical 200 mg per cap glycinate with NSF Sport at sub-$0.50 CPED would score 92+ and earn the TOP PICK position.
Who should buy this
Doctor's Best High Absorption Magnesium is best for:
- Buyers prioritizing clinical-dose magnesium at the lowest defensible cost. CPED $0.28 per day at full 400 mg clinical regimen is the lowest in the magnesium category.
- General consumers who do not need NSF Certified for Sport credentials. The premium for NSF Sport on Klean Athlete is approximately 215% per effective day.
- Long-term magnesium supplementers building a 6-12 month regimen. The 60-day-per-bottle supply is logistically convenient, and the cost compounds favorably across years.
- Buyers who want the Albion TRAACS technology specifically (the original patented chelated mineral system) and trust the 35+ year track record of Doctor's Best.
- Functional medicine patients on a budget whose practitioners do not require practitioner-grade brand specifically.
- iHerb regulars who already have an account and shop the brand frequently.
Doctor's Best High Absorption Magnesium is NOT for:
- Drug-tested athletes (NCAA, NFL, MLB, NBA, USOPC). No NSF Certified for Sport. Klean Athlete Klean Magnesium (BUY 87) is the right athlete-tier pick.
- Buyers with pill-swallowing difficulty. The tablets are physically large and the 4-tablet daily regimen multiplies this friction. Doctor's Best Magnesium powder or capsule formats are better fits.
- Buyers prioritizing practitioner-grade brand reputation specifically. Pure Encapsulations Magnesium Glycinate (BUY 84) and Thorne Magnesium Bisglycinate (BUY 88) deliver that signal at higher CPED.
- Buyers who want single-serving clinical dosing in one capsule or one scoop. Thorne Magnesium Bisglycinate powder hits 200 mg in a single scoop with simpler logistics.
- Buyers seeking magnesium L-threonate specifically for cognitive or neurological support. Magtein L-threonate is a separate use case (Doctor's Best has a Magtein product, but it is not this SKU).
Stacking notes
- Take across 2-3 daily doses rather than all 4 tablets at once. Recommended split: 2 tablets in morning and 2 tablets in evening, or 1 tablet at 4 spread points across the day.
- Schedule the largest single dose 30-60 minutes before bedtime to leverage glycine and magnesium combined relaxation effect on sleep latency.
- Pair with vitamin D3. Magnesium is a required cofactor for vitamin D activation in liver and kidney. Supplementing high-dose D3 without adequate magnesium yields blunted serum 25(OH)D response.
- Do not take with high-dose calcium supplements at the same time. Calcium and magnesium compete for the same intestinal transporter at saturating doses. Separate by 2 hours.
- Do not combine with potassium-sparing diuretics, ACE inhibitors at high dose, or digoxin without physician oversight.
- Cycling not required. Magnesium supplementation is a long-term intervention. Re-test serum or RBC magnesium every 90-180 days if you have known deficiency or specific clinical reason.
- For buyers stacking with creatine, taurine, or beta-alanine, magnesium supports the renal handling of all three. The full 400 mg daily regimen is appropriate during hard training blocks.
- Consider switching to powder version (Doctor's Best Magnesium Powder, Albion TRAACS, fruit punch) if tablet swallowing is a friction point or if you want slightly faster onset.
Better alternatives
If Doctor's Best High Absorption Magnesium does not fit your needs:
- Klean Athlete Klean Magnesium (EDE 87/100, CPED $0.88): NSF Certified for Sport, capsule form, 120 mg per cap. Best fit for drug-tested athletes.
- Pure Encapsulations Magnesium Glycinate (EDE 84/100, CPED $0.78): Practitioner-grade brand reputation, capsule form, 120 mg per cap. Best fit for buyers prioritizing institutional brand credibility at moderate premium.
- Thorne Magnesium Bisglycinate (EDE 88/100, CPED $1.25): Powder form, 200 mg per single scoop. Best fit for buyers wanting single-serving clinical dose simplicity.
- Doctor's Best Magnesium Powder (Albion TRAACS) (not yet scored): Same active form as the tablet version reviewed here, in powder format. Likely better real-world bioavailability and easier consumption. Worth considering if you tolerate flavored powders.
Frequently asked questions
Is Doctor's Best High Absorption Magnesium worth buying?
If you want clinical-dose magnesium glycinate at the lowest defensible cost, yes. EDE 81/100, $0.28 CPED at the full 400 mg clinical regimen, Albion TRAACS chelated form. The trade-offs are tablet form rather than capsule, no NSF Sport certification, and mid-tier brand reputation. For most general buyers without specific certification or brand requirements, this is the best CPED in the magnesium category.
What is the difference between magnesium glycinate and magnesium lysinate glycinate?
Both are chelated magnesium forms where elemental magnesium is bound to amino acid ligands. Magnesium glycinate uses two glycine molecules per Mg atom. Magnesium lysinate glycinate uses one glycine and one lysine molecule per Mg atom. They are clinically equivalent in absorption studies and both are top-tier bioavailability forms. The lysinate-glycinate combination is the original Albion TRAACS patented chelation; pure bisglycinate is a related Albion technology.
Why does Doctor's Best recommend 4 tablets per day?
Each tablet contains 100 mg elemental magnesium. The clinical effective dose for adult men is 300-400 mg per day. Taking 4 tablets (2 twice daily) delivers 400 mg, which is the upper end of the clinical range and matches the NIH RDA for men 31 and older (420 mg). This is unlike some products that recommend 1 capsule daily as the labeled serving with sub-clinical dose; Doctor's Best's labeled regimen is the actual clinical full dose.
How does Doctor's Best compare to Pure Encapsulations Magnesium Glycinate?
Same form family (chelated magnesium), different brands. Doctor's Best uses Albion TRAACS lysinate glycinate in tablet form at 100 mg per tab. Pure Encapsulations uses magnesium glycinate in capsule form at 120 mg per cap. Both reach clinical full dose at brand-recommended regimens. Pure Encapsulations has stronger practitioner-grade brand reputation. Doctor's Best has materially lower CPED ($0.28 vs $0.78). Score difference is 3 points; CPED difference is 64% lower for Doctor's Best.
Is this product third-party tested?
Doctor's Best claims "rigorously tested" but does not carry NSF Certified for Sport, USP Verified, or Informed Sport certification. The Albion TRAACS raw material is third-party verified at the ingredient level via Balchem certification. Public batch CoA is not consistently published. We rate Third-Party Testing at 50/100 for this product, reflecting raw material verification but absence of finished-product independent certification.
Will the tablets cause GI distress?
Unlikely. Chelated magnesium forms (including Albion TRAACS lysinate glycinate) do not draw osmotic water into the intestinal lumen the way magnesium oxide, citrate, or sulfate do, which is why those forms have laxative effects. Most users tolerate this product well at 4 tablets per day. If you have particularly sensitive GI, start with 2 tablets daily and titrate up.
Should I take the tablet version or the powder version?
Many user reviews on iHerb and Amazon report better subjective effect from the powder version of Doctor's Best Magnesium versus the tablet version. The powder is also functionally simpler (1 scoop daily versus 4 tablets) and may have slightly faster absorption due to immediate dissolution. If you tolerate flavored powders and want potentially better bioavailability, consider the powder. If you prefer pill-form supplements and want the lowest cost, the tablets are the right pick.
Can I take this with my multivitamin?
Yes, as long as the multivitamin's calcium content is not high (above 500 mg per serving). Calcium and magnesium compete for the same intestinal transporter at saturating doses. If your multivitamin has more than 500 mg calcium per serving, separate magnesium intake by at least 2 hours.

We recommend iHerb or Amazon for the cleanest supply chain at the lowest prices. Doctor's Best is widely distributed and the product is rarely out of stock.
Final verdict
BUY (value-tier). EDE Score 81/100. CPED $0.28 per effective day at the brand-recommended 4-tablet regimen.
Doctor's Best High Absorption Magnesium is the right magnesium for general buyers who want clinical-dose chelated magnesium at the lowest defensible cost. Albion TRAACS lysinate glycinate top-tier form, brand-recommended regimen reaches exactly 400 mg clinical full dose, 60 days of dosing per bottle, $0.28 CPED is the lowest in the entire magnesium category.
It is not a TOP PICK because tablet form has slightly lower bioavailability than capsule, no NSF Sport or USP certification, and brand reputation is mid-tier rather than practitioner-grade. The category currently has no TOP PICK because no entry yet combines optimal form, single-cap clinical dose, and gold-standard certification.
