Support bone strength and density with calcium, K2 and D3 combined A targeted bone health formula providing the key nutrients involved in bone mineral density maintenance and formation. Each capsule delivers 78mg calcium (as citrate, a well absorbed form), 27mg magnesium, 3.8mcg vitamin D3, 7.4mcg vitamin K2, 74mcg vitamin B12 (as methylcobalamin) and 0.4mg manganese alongside two bone specific additions: 14mg silicon (as choline stabilised orthosilicic acid) and 232mcg boron. Silicon is a required cofactor for collagen crosslinking in bone matrix, and orthosilicic acid is the most bioavailable supplemental form. Boron supports the metabolism of calcium, magnesium and vitamin D within bone tissue.Green tea extract at 83mg (45% EGCG) provides antioxidant support for osteoblasts (bone building cells), which are particularly sensitive to oxidative damage. The vitamin D3 and K2 pairing ensures calcium absorbed through the gut is directed into bone rather than depositing in soft tissues. This formula may contain up to 5mg of naturally occurring caffeine per capsule from the green tea extract. The vegetarian capsule shell makes this suitable for most dietary requirements.
