40% lack Vitamin D! Boost testosterone & muscle performance #Shorts

Over 40% of adults worldwide are Vitamin D deficient — and it directly affects testosterone production, muscle fibre recruitment, and immune function. For lifters, this is a major unaddressed performance leak.

2,000-4,000 IU of Vitamin D3 daily, taken with a fatty meal. Get your levels tested first if possible.
