Description

This supplement is designed to support bone health, immune function, and cardiovascular health, featuring 4000 IU of Vitamin D3 sourced from marine algae and 100mcg of Vitamin K2. This formulation ensures optimal calcium absorption while promoting strong bones and a healthy heart. Suitable for vegans, this product is ideal for athletes looking to maintain peak performance.

Why we made this product

We created the Vitamin D + K2 supplement for athletes and individuals who may be deficient in these essential vitamins. Low Vitamin D levels can impact muscle recovery, bone strength, and immune function. With this product, we aim to ensure that athletes and active individuals are provided with a high-quality, plant-based Vitamin D3 and K2 formula, tailored for their needs.

Full Ingredients List

Vitamin D3: 4000 IU
Vitamin K2 (MK-7): 100mcg
HPMC (Empty Capsule Shell)
Brown rice flour
Bamboo silica
Allergen warning: may contain soya

How to Take

For optimal results, take 1 capsule daily with water, preferably in the morning. Athletes should consider regular supplementation, especially during the winter months or periods of reduced sun exposure.

Our Vitamin D3+K2 supplement is of higher strength (Vitamin D3 4000IU). If you find the 4000IU strength too high, you can opt to take them once every 2-3 days instead of daily. This approach can be effective because both Vitamin D3 and K2 are fat-soluble, meaning they can be stored in the body's fat tissues and liver for future use.

Can I take this with other products in your range that contain Vitamin D3?

4000IU is a strong dosage of Vitamin D3. We would recommend consulting a doctor before consuming other products also containing Vitamin D3.

What if I want a lower daily dose than 4000IU?
