Cardiovascular Research Magnesium Taurate 125 mg

• Better absorptionC · 0 stars
  Claimed: “MAGNESIUM TAURATE is a scientifically designed amino acid-mineral complex which ensures maximal bioavailability of the essential macromineral, magnesium.” (label side panel); “Absorption: Magnesium taurate is a chelated form, which may enhance bioavailability.” (listing description (Notes))
  Credited: Magnesium (as magnesium taurate) 125 mg per capsule; 250 mg a day as directed (one capsule twice daily)

  We found no study in people comparing how well magnesium taurate is absorbed with other forms: in people, citrate, chloride, lactate, aspartate and an amino-acid chelate were each absorbed better than magnesium oxide, and the absorption studies we found for a taurine-bound magnesium were all in rats or mice given a different compound, magnesium acetyl taurate.

  Magnesium lowered blood pressure by about 2 mmHg in placebo-controlled trials at a median 368 mg a day, with 300 mg a day judged enough (this bottle directs 250 mg), and taurine lowered it at 1 to 6 g a day, but the label does not say how much taurine a capsule holds; blood pressure is only a stand-in for heart health, the one study of magnesium taurate itself had no comparison group and added potassium citrate, and the rest is a 1996 idea paper and a rat study.

• Muscle function and exercise recoveryB · ½ star
  Claimed: “Muscle Function and Recovery. Magnesium plays a role in muscle relaxation and contraction.” (listing bullet); “May assist in post-exercise recovery by supporting electrolyte balance.” (listing bullet); “May assist in post-exercise recovery” (listing description)
  Credited: Magnesium (as magnesium taurate) 125 mg per capsule; 250 mg a day as directed (one capsule twice daily)

  Placebo-controlled trials found less muscle soreness after hard exercise, but at 350 to 500 mg a day (this bottle directs 250 mg); a 300 mg a day trial in older women improved a physical-performance score without a placebo group; and reviews found no gain in muscle strength or power, and no help for leg cramps in older adults (mostly night-time cramps).

• RelaxationB · ½ star
  Claimed: “May promote relaxation” (listing description)
  Credited: Magnesium (as magnesium taurate) 125 mg per capsule; 250 mg a day as directed (one capsule twice daily)

  The evidence is mixed and weak: a review of 18 studies in anxiety-prone people found a benefit in about half of them, on poor-quality evidence; a stress trial at 300 mg a day enrolled people with low blood magnesium and had no placebo group; and three small placebo-controlled trials in older adults with insomnia cut the time to fall asleep by about 17 minutes, on low to very low quality evidence.

• HydrationC · 0 stars
  Claimed: “Helps maintain proper hydration and electrolyte levels in the body.” (listing description)
  Credited: Magnesium (as magnesium taurate) 125 mg per capsule; 250 mg a day as directed (one capsule twice daily)

  We found no randomized trial showing that magnesium supplements improve hydration; the closest, a small trial in which 200 mg a day eased premenstrual bloating and swelling in the second month, measured fluid retention, not hydration. PMID 9861593 ›

• Electrolyte levelsB · ½ star
  Claimed: “Helps maintain proper hydration and electrolyte levels in the body.” (listing description)
  Credited: Magnesium (as magnesium taurate) 125 mg per capsule; 250 mg a day as directed (one capsule twice daily)

  Magnesium is the one electrolyte this capsule supplies, and in trials magnesium supplements kept blood magnesium in the normal range and raised it slightly at about 300 mg a day, but in one 60-day trial at about 250 to 280 mg a day only the citrate form raised it significantly.

Competitors compared (7, checked 2026-10-09): Double Wood Supplements Magnesium Taurate 1,500 mg, 210 capsules (first non-sponsored result, 'Overall Pick'; #145 in Magnesium Mineral Supplements), KAL Magnesium Taurate+ 400 mg (#208 in Magnesium Mineral Supplements), Nutricost Magnesium Taurate 1,500 mg, 240 capsules, Nature's Branch Magnesium Taurate 400 mg, 200 capsules (#505), Natural Rhythm Magnesium Taurate 750 mg, 120 capsules (#324), NatureBell Magnesium Taurate 1,500 mg, 240 capsules (#578), Vitamatic Magnesium Taurate with B6, 180 capsules (#618). This product is magnesium taurate alone at 125 mg of magnesium per one-capsule serving; Double Wood, Nutricost, Nature's Branch, Natural Rhythm and NatureBell sell the same single ingredient at 100 to 150 mg per serving, while KAL and Vitamatic add magnesium oxide and vitamin B6 (KAL also adds black pepper, ginger, rosemary, turmeric and cayenne extracts). Its capsules hold more magnesium (125 mg, against 40 to 75 mg in those five), which changes how many capsules you take rather than the formula, so no material difference was found in 7 competitors as of 2026-10-09.

Prices compared, per 125 mg of elemental magnesium as magnesium taurate (one capsule of this product). Amazon one-time prices checked 2026-10-09: this product $0.17 (180 capsules at $30.60); Double Wood (210 capsules) $0.30, Nutricost (240 capsules) $0.23, Nature's Branch (200 capsules) $0.22, Natural Rhythm (120 capsules) $0.33, NatureBell (240 capsules) $0.23; median $0.23, so this product costs 0.73× the median.

How we rate. Six criteria, one star each. Clinical evidence: each claim the product makes is graded at this product's dose: A (1) randomized human trials show the effect at or below this dose; B (½) human evidence only at higher doses, with mixed results, or on stand-in measures; C (0) no randomized human evidence for the claimed effect. The grades are averaged. Third-party testing: listed in a certifier's public database (1), or batch certificates of analysis from a named lab (½). No synthetic dyes (1). No artificial sweeteners (1). Formulation: a difference that matters for its claims, found in none of the leading competitors (1), or only partly (½). Price: the cost of one standard dose (the main active in one serving, or one serving of a mix) at or below the median of the leading competitors (1), up to 50% above it (½), on Amazon prices read the same day.
