About the Product

Magnesium touches hundreds of processes throughout the body, from normal muscle and nerve function to energy production and bone health. Mag18 by Longevity Rx takes a different approach to daily magnesium, pairing the mineral with 18 amino-acid peptides in a formula designed around efficient mineral delivery.

Rather than relying on a single conventional form of magnesium, Mag18 uses a peptide-bound magnesium chelate created with hydrolyzed spirulina. The amino acids bind with magnesium to create a whole-food-inspired mineral complex designed to support absorption and utilization.

The formula is rounded out with zinc, copper, selenium and chromium, providing additional trace minerals involved in normal enzyme activity and numerous metabolic processes throughout the body. The zinc and copper are included in a balanced ratio rather than treating each mineral in isolation.

Mag18 also pairs magnesium with Vitamin D3 and Vitamin K2, two nutrients with complementary roles in calcium metabolism and maintaining normal bones. Vitamin D supports calcium absorption, while Vitamin K contributes to the maintenance of normal bone health.

Where Mag18 really earns its place in a daily wellness routine, however, is its versatility. Magnesium supports normal muscle function and nervous-system activity, making the formula particularly relevant for people balancing demanding workouts, busy schedules and the need to properly unwind at the end of the day.

That makes Mag18 an excellent evening supplement for anyone building a more deliberate recovery routine. Take it with dinner or another evening meal and allow it to become part of the transition from training and activity to relaxation and rest.

Mag18 is plant-based, Non-GMO and free from gluten, dairy, artificial sweeteners, colors and unnecessary fillers. It is manufactured in the USA in a GMP-certified facility and third-party tested for purity and potency.
