Pure Magnesium Glycinate (Bisglycinate), 240 Vegan Capsules, 2 Month Supply, High Strength 300mg Elemental, Bioavailable Chelated Supplement for Sleep, Muscle Cramps, UK Made - Love Life Supplements
LOVE LIFE SUPPLEMENTS
Why we love it
High strength, pure capsules.
Enhances quality of sleep.
Made in UK quality.

It is simply chelated with the amino acid glycine for maximum absorption and zero side effects.
SUPPORTS DEEP SLEEP & RELAXATION - Formulated for adults seeking nighttime support, magnesium helps calm the nervous system and maintain healthy sleep patterns. It is widely used by men and women to support relaxation, reduce tiredness, and ease the transition into restful sleep.
MUSCLE RECOVERY & CRAMP RELIEF - Essential for normal muscle function, this high strength mineral supplement helps relieve muscle aches, tension, and spasms. It is an ideal daily choice for active individuals, athletes, or anyone experiencing restless discomfort in their legs or body.
PURE, VEGAN & ZERO FILLERS - You receive exactly what your body needs: 300mg of elemental magnesium per serving. We use absolutely no bulking agents, binders, or nasty excipients. The clean formula is encapsulated in an easy-to-swallow vegan shell, suitable for all daily diets.
PREMIUM UK MANUFACTURING - Love Life Supplements are proudly produced in the UK under strict BRC and GMP certification standards. We guarantee the highest quality, safety, and purity in every batch of our magnesium capsules, ensuring you can trust what you put into your body.
