Magnesium taurate is a 1-to-2 salt of elemental magnesium (≈ 8-9 % Mg by weight) and the amino-sulfonic acid taurine. The pairing is attractive because — in theory — you get:

• the cardiometabolic and neuromuscular roles of magnesium, plus

• taurine’s own blood-pressure-, insulin- and membrane-stabilising actions

• In salt-loaded spontaneously hypertensive rats, oral taurine + high-Mg diet normalized endothelial-progenitor cell function and reduced oxidative stress; a short pilot in healthy men reproduced the antioxidant/EPC effects after 2 weeks.
• A recent review again highlights the BP-reducing potential of taurine-bound Mg salts. Moderate (animal) / emerging (human) Cardioprotection Mg-taurate attenuated cadmium-induced cardiotoxicity and lipid peroxidation in rat myocardium. Animal data Eye health In galactose-fed rats, Mg-taurate slowed cataractogenesis by normalizing lenticular oxidative markers and blood pressure.
Magnesium acetyl-taurate protected retinal ganglion cells from NMDA damage, pointing to broader neuro-ocular protection. Animal data Glucose & insulin Mg improves insulin-receptor signaling; taurine enhances β-cell function. Animal work shows combined Mg-supplementation improves insulin sensitivity in diabetic models.
Reviews list Mg-taurate as a candidate for glycaemic control. Animal / mechanistic Anxiety, sleep & neuroprotection Systematic reviews of magnesium (various salts) suggest benefit for mild anxiety and insomnia, especially when baseline Mg is low.
Popular clinical summaries single out taurate and glycinate forms for good tolerability and CNS penetration. Low–moderate (mostly mixed-salt data)
