Swisse Ultiboost Magnesium

Swisse Ultiboost Magnesium contains a blend of several bioavailable forms, including magnesium citrate, magnesium glycinate, and magnesium L-threonate. Each form has different absorption characteristics—citrate is well-absorbed for general muscle function, glycinate is gentle on the stomach, and L-threonate has been studied for its ability to cross the blood-brain barrier. The supplement also includes Vitamin B6 and Boron as cofactors.

Swisse Ultiboost Magnesium is marketed to support muscle function, relaxation, and relief from muscle cramps and spasms. Magnesium plays a role in neuromuscular signaling and muscle contraction, and the citrate and glycinate forms in this blend are among the better-absorbed options. However, scientific evidence for magnesium supplementation relieving cramps in healthy individuals remains mixed.

Magnesium L-threonate is a relatively newer form of magnesium that has been shown in research, including studies at MIT, to effectively cross the blood-brain barrier and potentially support cognitive function. Its inclusion in Swisse Ultiboost Magnesium distinguishes the product from basic magnesium supplements that only contain magnesium oxide, which has poor bioavailability.
