Weider's trisource magnesium blend uses citrate, malate and bisglycinate for high bioavailability, designed for athletes and physically active people. The star ingredient bisglycinate (often called magnesium glycinate) aims for reliable absorption. Vegan capsules with no fillers reflect our commitment to clean, transparent sourcing and careful quality checks. Magnesium functions as a cofactor for around 300 enzymatic reactions, supports muscle contraction and relaxation, and about 65 percent is stored in bones for density and strength. This isn’t a vitamin d supplement.

The Active Ingredient Is: Magnesium (Tri-form Complex)

Magnesium becomes a vital mineral that participates in hundreds of enzymatic reactions and supports normal muscle function, energy metabolism, and bone structure (which is handy for daily energy balance).

This formula combines magnesium citrate, magnesium malate, and magnesium bisglycinate to provide a highly bioavailable source, and it is designed to meet increased magnesium demands for athletes and physically active individuals

What Does Magnesium Do?

Magnesium helps with energy metabolism and muscle contraction and relaxation, and is involved in normal nervous system signalling and electrolyte balance, which basically means it supports how you feel day to day

Dr. Patel from the University of Nottingham found that magnesium participates in energy metabolism and muscle function

It also helps support bone density, helps to reduce tiredness, and supports normal psychological function as recognised in EFSA-aligned guidance (which matters for balance across daily life)
