The Ultimate Human Vitamin D3 K2

Product description

Key Benefits

The Ultimate Human Vitamin D3 + K2 combines two essential vitamins in carefully selected forms for everyday supplementation. Designed to complement a balanced diet, each serving delivers vitamin D3 alongside vitamin K2 in a convenient daily dose.

Vitamin D contributes to the normal absorption and utilisation of calcium and phosphorus, while vitamins D and K both contribute to the maintenance of normal bones. Vitamin D also contributes to the maintenance of normal muscle function, normal teeth and the normal function of the immune system.

Simple to take and easy to incorporate into your daily routine, it's a considered addition to everyday nutrition.
