Why this certification matters
- Informed Sport
- Informed Sport certification is especially relevant for athletes in tested sports because products are batch-tested for substances prohibited in sport.
Frequently asked questions
- Why pair D3 and K2?
- The two vitamins are typically paired because vitamin K2 is involved in directing calcium to bone and teeth, complementing D3's role in calcium absorption. The interaction is the rationale behind combination D3+K2 products.
- Where can I buy Nutriburst Vitamin D3 + K2?
- Amazon UK lists at £7.99 and Holland & Barrett at £11.99 — Amazon is currently noticeably cheaper, though H&B promo cycles can close the gap.
- Is the Informed Sport cert meaningful on a gummy?
- For tested athletes who want banned-substance screening across every supplement, yes — Informed Sport tests each batch regardless of category. Most high-street gummies don't carry it.
- Are these vegan?
- Many gummies use gelatin; some use pectin. Check the live Amazon or Holland & Barrett listing for the ingredients of the specific batch.
- How does this compare to a D3-only product?
- A D3-only gummy or tablet skips the K2. Whether to add K2 is a personal call — bone-health regimens sometimes pair them, but D3 alone is also widely recommended.
