Multivitamins Containing Vitamin D3 (Cholecalciferol)
The most evidence-based daily multivitamin on the market. Every one of its 26 ingredients is backed by human RCTs at the exact dose used in clinical trials — methylated B vitamins, glycinate-form minerals, 200mg hyaluronic acid for skin health, TMG for cognition and exercise, and microencapsulated carotenoids for eye protection. It deliberately excludes Vitamin A and E based on safety research, and consolidates 6–8 separate supplements into one formula.
