Nutrition and training experts constantly lecture bodybuilders about the importance of vitamins and minerals. The good news is that most bodybuilders take a daily multivitamin. The bad news is that many bodybuilders are still deficient in vitamins. Vitamin D is an important vitamin that many bodybuilders lack despite taking a multivitamin daily.
A new study presented at the American Academy of Neurology showed that low vitamin D levels are, in some cases, related to brain shrinkage and dramatic declines in cognition (thinking ability).
For bodybuilders, the mind-muscle connection is everything. To grow, you have to feel your muscles through every phase of the repetition. If you’re deficient in vitamin D, not only will you fail to build muscle because of a loss of mind-muscle connection, but another important organ will shrink: your brain.
So here’s your FUSION FACTOID: Make sure you’re getting enough vitamin D of all types from all sources. (Sunlight is a great natural vitamin D source!) Examine your multivitamin supplement, and check this against your needs as a bodybuilder. Make up the difference through supplementation. Failure to do so can cripple your muscle gains and make your brain stupid in the long run.
