Magnesium+ — Three Forms. Superior Absorption. Real Results.
260mg elemental Magnesium. Ashwagandha. Vitamin B6 at 3,570% NRV. Not all magnesium supplements are equal.
Most magnesium supplements use Magnesium Oxide — a cheap form with poor bioavailability. You swallow the capsule and most of it leaves without doing much.
Magnesium+ uses three premium forms — Bisglycinate, Malate and Citrate — chosen for superior absorption. 260mg of elemental Magnesium per daily dose, actually reaching where it's needed.
Ashwagandha Root adds adaptogenic depth, supporting stress resilience and the hormonal balance that sleep, energy and body composition all depend on. Vitamin B6 at 50mg (3,570% NRV) supports energy metabolism and maximises the effectiveness of the formula.
Take during the day for energy and focus. Take before bed for muscle recovery and deeper sleep. 90 capsules.
