Bigger Muscles & Better Work Outs with B Vitamins

Sport and exercise are important. But strenuous exercise can damage and even injure your muscles. Muscle regeneration can be a slow process. New research is suggesting that a duo of B vitamins can speed it up.

After muscle damage, muscle regeneration is driven by muscle stem cells.

A just published double-blind, placebo-controlled study asked 39 men with an average age of 26.7 years to do a single session of damaging high intensity muscle contractions. It then gave them either a placebo or 714mg of B3 in the form of niacinamide and 19mg of B6 for 9 days.

The B vitamins was significantly more effective than placebo. Muscle stem cells were 29% higher, and regenerating muscle fibers were 37% higher. The B vitamins were safe and caused no adverse events.

There are no conventional treatments that specifically target muscle stem cells for promoting muscle repair and recovery. But this study shows that a combination of B3 and B6 enhances muscle stem cells and accelerates muscle regeneration and repair.
