Protein Optimisers will be the overiding name for a new series of supplements set to be released by Musashi in April this year. Consisting of three products that are designed to be added to protein powder, the new supplements are another new line in Musashi's already extensive sport supplement line up. With the names, 'Calming (magnesium)', 'Muscle (creatine)' and 'Immune (glutamine)', the new supplements more or less explain themselves. But it's hard to argue that the major active ingredients of each (highlighted in brackets above) are particularly ground breaking or revolutionary. With basic ingredients such as these, Musashi may be trying to target novice weight trainers new to supplements, rather than your typical educated savvy supplement user.
