What the product contains and what one serving costs, according to our catalog. Label amounts are not personal dose recommendations.
| Ingredient | Amount per serving |
|---|---|

| Vitamin K2 | 90 µg |
Amounts are per label serving as recorded in the catalog and are not a recommendation. Testing status reflects what the brand lists. Nothing here is medical advice.
These calculations describe our scoring method. They are not a recommended dose or proof of benefit from this product.
Full trial dose, public lab certificate, tested by independent lab.
Read the evidence (2 studies)Evidence gates dose: the evidence grade sets the ceiling, and the dose decides how much of that ceiling the product reaches. Value = inverse of price-per-trial-dose-day. Community = mean sentiment of external reviews. Safety caps applied after weighting.
This score is our editorial judgment, not a scientific standard. We combine published evidence, dose, price, transparency, and consumer signals into one composite: this is our method, not a peer-reviewed clinical rating. A higher score means a product does better on the factors we weight, not that it is medically proven to work.
This Nordic Naturals Vitamin D3+K2 scores 8.9, making it one of the highest-scoring products on the site. It delivers 0mg of Vitamin D3, inside the studied range of 0–0mg with grade A evidence (strong human trial data). Transparency is a clear strength (score: 9.0), with third-party testing and a public lab certificate. At $0.33/day it's priced well for what you get.
The science behind each active ingredient, independent of which brand sells it.
Cheap, safe, and correcting a deficiency you probably have.
Vitamin D3's essential partner, directs calcium to bones instead of arteries.
Every active in this formula, its declared dose per serving, the dose used in the primary human trial, how much of that trial dose this product delivers, and the evidence grade for the ingredient itself.
| Ingredient | Dose / serving | Research dose | % of research | Evidence grade |
|---|---|---|---|---|
| Vitamin D3 | 0.05 mg | 0.05 mg | 100% | A |
| Vitamin K2 | 0.09 mg | 0.18 mg | 50% | B |
Percentages are dose per serving ÷ primary trial dose. Below 50% means the formula is unlikely to reproduce the trial outcome for that active. Grade A = multiple large human RCTs. Grade F = no human evidence. How grades work. Full glossary →

This is a brand-level customer-service profile for nordic-naturals; it does not isolate Vitamin D3+K2.
Community discussion exists around Vitamin D3+K2, balancing reported energy and joint benefits and brand recommendations against dosage and safety concerns. No single Reddit thread is treated as a representative product review.
Nordic does not sell a standalone Vitamin K2 product, this combo softgel is the closest match, pairing 2000 IU D3 with 90 mcg K2 as MK-7 (the well-absorbed, long-half-life form) in one daily softgel at $19.95 for 60 servings.
