The Relationship Between Vitamin D3 and K2: Do You Need Both?

Unravelling the connection between Vitamin D3 and K2 and when it's essential to take them together.

Updated this week

At Together Health, we're committed to providing clarity on the intricate dynamics of supplements. A recurring question we encounter is about the relationship between Vitamin D3 and K2 and whether it's necessary to take them in tandem.

Vitamin D3, K2, and Calcium: The Triad of Bone Health

Vitamin D3 and K2 share a pivotal role in calcium metabolism within the body. Their primary function is to ensure calcium is effectively absorbed into our bones, preventing its accumulation in our arteries. Recognising this synergy, we've incorporated all three in our Bone Aid product, offering a comprehensive solution for bone health.

When Do You Need K2 with D3?

While the relationship between D3 and K2 is undeniable, it's not always necessary to take them together. If you're supplementing with D3 due to seasonal changes or identified deficiencies, adding K2 isn't always required. This is because D3 deficiency is a common concern in the UK, whereas K2 deficiency is rare due to the body's ability to create its own.

However, there are specific scenarios where the combination becomes crucial. If you're consuming megadoses of D3 (exceeding 100 mcg), there's evidence suggesting a potential increase in calcium deposits in the arteries. In such cases, K2 can play a protective role, ensuring calcium is directed to the bones and not the arteries. It's worth noting that our products are formulated to avoid such concerns.

Why the Combined Products in Stores?

The supplement industry is vast, and marketing plays a significant role in product formulation. While the D3 and K2 combination is beneficial for certain individuals, it's not universally required. The inclusion of both in many products is often a marketing strategy to make one product seem superior to another.

At Together Health, our approach is different. We prioritise the genuine health benefits of our products over marketing tactics. While many companies might use inexpensive synthetic ingredients, allowing them to add more without significant cost implications, we choose natural ingredients, which are more costly. This choice means we must formulate our products intelligently to ensure they remain affordable without compromising on quality.

In conclusion, while Vitamin D3 and K2 share a vital relationship, it's essential to understand when and why they should be taken together. Our commitment is to provide you with products that offer genuine benefits, formulated with the best ingredients, and at an affordable price.
