Overview
Combination vitamin D3 and K2 softgel from Nutricost, pairing 5000 IU of D3 with 100 mcg of MK-7 vitamin K2 in a single 120-count, gluten free, non-GMO bottle, aimed at buyers who want both nutrients together.
Pairing D3 with K2, specifically the longer-acting MK-7 form, reflects the theory that K2 helps direct the calcium D3 helps absorb toward bones rather than soft tissue, which is why the two nutrients are increasingly sold together rather than in separate bottles.
- 5000 IU vitamin D3 with 100 mcg MK-7 K2
- 120 softgels, about four months' supply
- Gluten free formula
- Non-GMO
Who it's for
Buyers who want D3 and K2 combined in one softgel instead of stocking two bottles, at a value price point. Not for someone who only wants D3 alone or a dose lower than 5000 IU.
Strengths and trade-offs
Drawn from this product's published specifications.
- Combines D3 and K2 in one softgel
- Non-GMO and gluten free
- Moderate 5000 IU dose
- 120 count is a shorter supply
- No ingredient details beyond the label
Performance notes
At 5000 IU, the D3 dose sits above the standard RDA but below very high-dose products, while the 100 mcg MK-7 form of K2 is the longer-acting variant compared to MK-4. The 120-count bottle covers about four months at one softgel a day.
