Bevisning 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. Säkerhet 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.
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.
The specific product: dose, price, transparency, and what buyers report.
Säkerhet flags, transparency gaps, dosing concerns, and recurring buyer complaints.
All product data is checked against original sources. Prices, doses, and testing status are updated when product pages change. Bevisning grades are reviewed when new human RCTs are published. Read how we verify.

These are consumer sentiment signals. They do not measure whether the product actually works. See our evidence section for that.
Public sources on this same product, unrelated to NO1GEVITY. NIH DSLD is the US government's registered label database (shown verbatim). SuppCo.com is a separate, unaffiliated commercial site with no partnership or data-sharing arrangement with us. NO1GEVITY scores are computed independently of both.
SuppCo is a separate, unaffiliated supplement-tracking site with no partnership, data-sharing agreement, or business relationship with NO1GEVITY. We are not endorsed by them and they do not endorse us. The two facts below are individually verified against the manufacturer or NSF; the outbound link is provided only so readers can independently cross-check on a third-party site if they want to.
We treat external opinion very differently depending on where it comes from. Tier A is our strongest signal. Tier C is background sentiment only. Tier Rejected is what we excluded, listed openly so you can see what we discarded.
These reviews are aggregated from third-party sources, not written by NO1GEVITY. Each entry shows its source, retrieval date, and whether the source has an affiliate or paid relationship. We do not edit reviews to change their meaning. Disclosure policy.
Our strongest external evidence. Long-form independent reviews, physical-product lab work, and third-party certifications.
Independent corroboration of the dose-mismatch concern raised in this dossier's claim_check.
Generally favorable category-level quality signal, not product-specific confirmation.

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 portioner.
This Nordic Naturals Vitamin D3+K2 scores 8.3, making it a strong scorer. It delivers the full 0.05mg trial dose of Vitamin D3 with grade A evidence (strong human trial data). Transparency is a clear strength (score: 9.0), with third-party testing and a public analysintyg. At $0.33/day it's priced well for what you get.
If you are the manufacturer or brand owner of Vitamin D3+K2 and believe any data on this page is incorrect (wrong dose, wrong ingredient, wrong price, missing certification, outdated status), you can request a correction.
