Protein Rebel launches seawater magnesium for runners

The UK-based company designed Power Up to support muscle recovery, boost energy levels and aid sleep, aiming to improve runners’ rest and recovery between training sessions. 

As Tim Boote, co-founder of Protein Rebel explained to NutraIngredients, magnesium specifically is often lacking in the diets of those with an active lifestyle.

Research shows that 60% of the adult population​ is not getting the recommended daily amount of magnesium, and runners are at greater risk of magnesium deficiency because they lose the mineral through sweating​.

Recovery product

Protein Rebel formulated its product based on the UK’s RDI of magnesium: 300 mg a day for men (19 to 64 years) and 270 mg a day for women (19 to 64 years).

Boote explained the brand sources magnesium from seawater because it is more readily absorbed by the body and contains a higher concentration of trace minerals to support overall health.

He noted that seawater-derived magnesium is also considered more sustainable than land-based sources, which aligns with brands commitment to sustainability.

Magnesium must be combined with another molecule to be absorbed by the body, resulting in different magnesium compounds like magnesium citrate, chloride and oxide. 

There are 10 main types of magnesium compounds, each with varying amounts of magnesium and bioavailability; however, some like magnesium oxide contains a high level of magnesium but have been shown to have low bioavailability​, so the body can only use a small portion of it.

The magnesium is combined with citric acid to produce magnesium citrate, which Boote explained is a highly bioavailable type of magnesium.
