Thank you so much for taking the time to share your concerns. We're glad you reached out so we can clarify how our product is formulated and how it fits within current guidance.
Vitamin D3 and Vitamin K2 can be taken together, but they are not universally required to be combined. While some brands choose to include both in a single capsule, it isn’t a regulatory or clinical requirement. Current UK and EU guidance does not state that D3 must be taken with K2, and Vitamin D supplements without K2 are widely used and considered safe.
Our D3 is formulated as a standalone supplement because many people already obtain Vitamin K through their diet or prefer to manage their intake separately. Combining nutrients in one capsule can be helpful for some, but it can also limit flexibility for those who need different strengths, are already taking K2 from another source, or have been advised to tailor their intake differently.
Regarding the concern about calcium “going to the wrong places,” it’s important to note that this is an area of ongoing scientific interest, and current regulatory bodies, including the European Food Safety Authority and the UK Department of Health, have not issued guidance stating that D3 should only be taken alongside K2. If such a requirement existed, we would of course follow it.
That said, we absolutely understand that some customers prefer to take D3 and K2 together, and we’re always reviewing emerging research and customer feedback when considering future formulations.
Your point about clearer labelling is genuinely appreciated. We never want anyone to feel unsure about how to use our products, and your feedback will be passed to our product and compliance teams so we can look at how to make this even clearer for customers.
If you’d like to take D3 and K2 together going forward, you’re very welcome to pair our D3 with a separate K2 supplement. Many customers prefer this approach because it allows them to choose the exact strength and form that suits them best.
