Overview
Bio-Tech Pharmacal's D3-50 delivers a high 50,000 IU dose of vitamin D3 per capsule in a 100-count bottle, positioned for bone, heart, neuromuscular and immune health support.
At 50,000 IU per capsule, this is a substantially higher dose than the 1,000 to 5,000 IU found in typical daily vitamin D products, so it's meant for a specific dosing schedule rather than everyday casual use, and dosing should be understood before starting. The product is free of dairy, fish, gluten, peanut, shellfish and soy.

Who it's for
