Vitamina D3 y K2 de Metabolic Maintenance, 25.000 UI, 60 Cápsulas

What is the combination of vitamin D3 and K2?

Vitamin D3 (cholecalciferol) and vitamin K2 (menaquinone) are two fat-soluble nutrients that work synergistically to promote bone and cardiovascular metabolism. While vitamin D3 contributes to the normal absorption and utilization of calcium and phosphorus, vitamin K2 helps direct calcium to the bones and teeth, supporting their maintenance under normal conditions. This combination is especially relevant for those seeking complete support for bone health.

Health benefits

According to the European Food Safety Authority (EFSA), vitamin D3 contributes to the maintenance of bones under normal conditions, to the normal absorption and utilization of calcium and phosphorus, to the maintenance of normal blood calcium levels, and to the normal functioning of the immune system. For its part, vitamin K contributes to the maintenance of bones under normal conditions and to normal blood clotting.

• Bone health: Vitamin D3 promotes calcium absorption, while K2 activates osteocalcin, a protein that fixes calcium in the bone matrix.
• Immune function: Vitamin D3 contributes to the normal functioning of the immune system, helping to maintain the body's defenses.
• Cardiovascular health: Vitamin K2 helps prevent the accumulation of calcium in the arteries, contributing to the health of the circulatory system.

Food supplements should not be used as a substitute for a balanced diet. Do not exceed the recommended daily dose. Keep out of reach of young children.
