What the research says about magnesium, potassium and taurine
Peer-reviewed studies and reviews on magnesium, potassium, taurine and this combination generally - shared for education, not as claims about this finished product. Mag-K-Taurine's claims are the statements authorized under its Natural Health Product licence, NPN 80059998.
A systematic review links taurine to cardiovascular benefits
A systematic review and meta-analysis of the evidence on taurine supplementation found consistent associations with favorable cardiovascular outcomes, synthesizing findings across multiple human studies.
Systematic Review/Meta-analysisTaurine supplementation increased exercise capacity in heart failure patients
In a randomized, single-blind, placebo-controlled trial of 29 patients with heart failure (NYHA class II-III), 500 mg of taurine three times daily for two weeks significantly increased exercise time, metabolic equivalents and exercise distance compared to placebo.
Human RCTA systematic review found mixed evidence but no safety signal for taurine in heart failure
Reviewing 11 human studies on taurine supplementation for dilated cardiomyopathy and heart failure, researchers found the pooled effect on ejection fraction and stroke volume was not statistically significant, though individual studies reported improvements in exercise capacity and hemodynamic parameters, with no significant safety concerns identified.
Systematic ReviewMagnesium and potassium supplementation improved insomnia and sleep hormones
In a randomized controlled trial of 290 diabetic patients with insomnia, magnesium, potassium, and a combined magnesium-plus-potassium supplement each significantly improved Insomnia Severity Index scores and normalized serum melatonin and cortisol (sleep hormone) levels compared to placebo over two months.
Human RCTIntravenous magnesium did not reduce nocturnal leg cramps in a controlled trial
In a double-blind, placebo-controlled trial of 46 older adults with rest cramps, five days of intravenous magnesium infusion did not significantly reduce weekly cramp frequency compared to placebo - an honest reminder that magnesium's cramp-related evidence is mixed.
Human RCTA Cochrane review found inconsistent evidence for oral magnesium in pregnancy leg cramps
A Cochrane systematic review of six trials (390 women) found oral magnesium did not consistently reduce the frequency of leg cramps in pregnancy compared to placebo, though some measures showed a possible reduction in pain intensity - the evidence was graded low to very low quality.
Cochrane ReviewGenetic research shows why low potassium can paralyze muscle
A review of hypokalemic periodic paralysis describes how mutations affecting voltage-gated ion channels destabilize the muscle cell's resting membrane potential during low-potassium states, causing reversible loss of muscle excitability - illustrating potassium's fundamental role in muscle function.
ReviewSweat electrolyte study measured real potassium loss during daily activity
In 285 Chinese adults performing brisk walking, running or cycling for 60 minutes, sweat samples showed measurable sodium and potassium losses that varied by activity type and sex, with women showing higher sweat potassium concentrations than men.
Cross-sectional studyA potassium-enriched sports drink improved postexercise rehydration
Comparing a traditional sports drink, a high-potassium sports drink, a milk-permeate drink and water after exercise-induced dehydration, the milk-permeate drink (with the highest potassium content) produced significantly better net fluid balance and lower cumulative urine output than the other options.
Human RCTMagnesium and taurine share a cardioprotective mechanism during ischemia
A mechanistic review describes how magnesium and taurine each help limit calcium overload and reactive oxygen species during cardiac ischemia-reperfusion injury, with taurine's osmoregulatory role triggering a cytoprotective signaling pathway - complementary mechanisms studied together in cardiac stress models.
Mechanism/ReviewA nutrient-matrix review highlights magnesium, potassium and taurine together in cardiometabolic health
Reviewing sardines as a food source, researchers noted that calcium, potassium, magnesium and taurine occur together in meaningful amounts and may jointly modulate the inflammation and oxidative stress implicated in cardiovascular disease, beyond the omega-3 fatty acids usually credited.
ReviewCombined magnesium and potassium supplementation improved insulin resistance
In a 320-patient randomized controlled trial, a combined magnesium-plus-potassium supplement produced the largest reduction in insulin resistance (HOMA-IR) and fasting blood sugar among insomniac patients with diabetes, compared to magnesium alone, potassium alone, or placebo.
Human RCTAn energy-drink component-isolation trial found taurine did not raise blood pressure
In a randomized crossover trial isolating individual energy-drink ingredients, caffeine significantly raised systolic blood pressure and prolonged the QTc interval, while taurine and glucuronolactone alone did not - suggesting taurine specifically was not responsible for the cardiovascular changes seen with energy drinks.
Human RCTPotassium chloride supplementation carries a real, dose-linked hyperkalemia risk
In 191 patients with chronic kidney disease given 40 mmol of potassium chloride daily for two weeks, plasma potassium rose by 0.4 mmol/L on average and 11% of participants developed hyperkalemia, more often those who were older or had higher baseline potassium - real safety data specific to the potassium chloride form used in this product, and part of why combining potassium supplements is not recommended.
Human RCTA taurine-containing supplement was well tolerated over 180 days
In a double-blind, multicenter, placebo-controlled trial of a taurine-plus-N-acetylcysteine supplement in chronic kidney disease patients, only mild adverse events were reported in five participants over six months, with no clinically significant safety events.
Human RCTSeawater-derived magnesium citrate and hydroxide both raised absorption substantially
In a double-blind crossover trial, both a seawater-derived magnesium citrate and a seawater-derived magnesium hydroxide preparation increased magnesium absorption by more than 97% compared to placebo, performing comparably once doses were equalized.
Human RCTA review confirms magnesium citrate and potassium chloride are both well-absorbed salt forms
Reviewing randomized trials on mineral bioavailability, researchers concluded that potassium chloride and potassium citrate both show good bioavailability regardless of dose, as do magnesium citrate and magnesium chloride, while magnesium oxide is poorly absorbed due to low water solubility.
ReviewMagnesium citrate showed higher bioavailability than magnesium oxide
In healthy men pre-saturated with magnesium, a single 400 mg dose of magnesium citrate produced significantly higher 24-hour urinary magnesium excretion and blood plasma magnesium than the same dose of magnesium oxide.
Human RCTTaurine's biochemical roles in cell protection
A review of taurine's biochemistry describes its function in cellular osmoregulation, its role in limiting sodium/calcium exchange overload, and its ability to trigger a protective cell-signaling pathway - foundational mechanisms behind its studied role in cardiac tissue.
ReviewA modern review maps taurine's multifaceted metabolic roles
A review of taurine biology describes its roles in bile acid conjugation, osmoregulation, antioxidant defense and mitochondrial support, noting that human trials of 1-6 grams per day suggest metabolic benefits without significant adverse effects.
ReviewPotassium chloride and potassium citrate are handled differently by the kidney
In a crossover trial in healthy adults, an acute oral load of potassium chloride and potassium citrate produced a similar rise in plasma potassium, but potassium citrate led to greater red blood cell potassium uptake and urinary potassium excretion - foundational electrolyte-handling research on the specific potassium salt form used in this product.
Human RCTDifferent magnesium compounds show distinct dose-dependent tissue absorption
Testing magnesium citrate, malate, glycinate and acetyl taurate at three doses in mice, researchers found each organic magnesium compound had a distinct dose-response pattern for brain and muscle tissue magnesium levels, with magnesium acetyl taurate - a magnesium-taurine compound - notably raising brain magnesium at every dose tested.
Animal studyTaurine dose comparison shaped repeated-sprint performance in heat
Comparing 1 g, 4 g and 6 g doses of taurine against placebo before exhaustive exercise in high heat and humidity, researchers found taurine's effects on power output and time to exhaustion were dose- and sex-dependent, with higher doses more effective in men and lower-to-moderate doses more effective in women.
Human RCTHuman trials support taurine doses of 1 to 6 grams per day
A review of taurine supplementation research concluded that human trials using 1 to 6 grams per day suggest the amino acid can support metabolic resilience and mitochondrial function without significant adverse effects, though usual physiological synthesis and dietary intake are sufficient to maintain basal health.
