Key Benefits

• Combined D3, K1, and K2 formula.

• Vitamin D contributes to immune function.

• Vitamin D supports calcium absorption.

• Vitamin K contributes to normal bones.

• Vitamin K supports normal blood clotting.

Vitamin D3 Pro Softgels combine vitamin D3 with vitamins K1 and K2 in one daily formula. Vitamin D contributes to the normal function of the immune system, the maintenance of normal bones and teeth, and the normal absorption and utilisation of calcium and phosphorus. Vitamin K contributes to normal blood clotting and to the maintenance of normal bones. Bringing these nutrients together reflects how they are often used in the body, particularly where calcium balance matters.

The softgel format is easy to take and fits well into structured daily routines, including those that support regular training and active lifestyles. Vitamin D3 Pro Softgels offer a clear, practical way to include vitamins D and K as part of consistent nutritional intake.
