Biocyte Vitamin D3 Liposomal contributes to maintaining bone health, thanks to vitamin D3 or cholecalciferol, which is involved in bone mineralization by fixing calcium on bones, cartilage, and teeth. It also helps maintain calcium levels in the blood. Biocyte Vitamin D3 provides 50 micrograms of vitamin D per capsule, making it suitable for postmenopausal women to improve bone health, for people who want to strengthen bones and muscles, and for those who suffer from general fatigue or lack of sun exposure.
