The Sunshine Vitamin
No athlete gets perfect conditions all the time. Be prepared for the imperfect.
Vitamin D, known as the “sunshine vitamin,” can contribute to healthy immune function, muscle recovery, and the absorption of calcium and other nutrients — and avoiding vitamin D deficiency can help diffuse muscle pain and reduce muscle weakness.* Supplementing with TB12 Vitamin D can help your body perform better when ideal sunlight exposure isn’t possible, like during winter or an indoor training season.* Certified for quality and safety by the NSF Certified for Sport® Program, TB12 Vitamin D helps you shine.
