About this item
- ONE MINERAL, SO MANY FUNCTIONS! – Human body utilizes magnesium in over 300 metabolic reactions, serving as a metabolism booster and energy booster. Magnesium supplements are also useful for normal blood pressure support, lower cholesterol and overall heart health.*
- THE BEST NATURAL MUSCLE RELAXER! – Research shows that magnesium oxide is the best cramp defense for leg cramps.* Regular supplementation may help with sore muscle relief and recovery after tough workouts.*
- RELAXATION AND SLEEP SUPPORT - Twinlab magnesium oxide supplement supports relaxation and natural calm sleep.* Unlike some other anxiety relief items that form dependence and make you feel dizzy, our non-habit forming magnesium for sleep prolongs sleep and makes you wake up fresh and rested.* Research also shows that using magnesium for migraines is reasonable.*
- AND MORE! - Studies have shown that elemental magnesium helps regulate essential elements like calcium, phosphorus, sodium and potassium to support bones’ mass, density and overall bone health.* Using magnesium for constipation relief is scientifically backed as magnesium attracts water into the intestines, stimulating bowel mobility. Also, magnesium oxide neutralizes stomach acid and may provide gird relief.
- PROVEN QUALITY, INNOVATION AND TRADITION – Twinlab Magnesium Caps is an ultra-concentrated and potent mineral supplement, free of artificial flavors, colors and sweeteners, soy, sodium and gluten free, manufactured in a GMP certified facility and 3rd party lab-tested.
