Vegavero Vitamin D3 7000 IU + 200 µg Vitamin K2 vs Vitamin D3 5000 IU

Q: Why do 97% of UK vitamin D supplements lack third-party certification?

Of 35 vitamin D products in our database, only 1 carries third-party certification. That means 97% of the vitamin D supplements sold in the UK have no independent verification of what's actually in the bottle. UK regulations don't require third-party testing for supplements, so most brands skip it to save money. If certification matters to you, NOW Foods and Thorne are the brands scoring highest in our rankings, with overall scores of 85-87/100.

Q: Do you need vitamin K2 with high-dose vitamin D?

Our data shows that Thorne Vitamin D + K2 Liquid is the only combination D3+K2 product scoring 87/100 in our database of 35 vitamin D supplements, tying with two NOW Foods D3-only products for the top spot. Clinical research suggests K2 helps direct calcium to bones rather than arteries, which may matter at doses above 4000 IU daily. If you already eat K2-rich foods like natto, hard cheese, or egg yolks, a standalone D3 product may be sufficient.

What the Data Says

Why do 97% of UK vitamin D supplements lack third-party certification?

Only 1 out of 35 vitamin D products we scored has independent certification. That's 97% without any third-party verification of purity, potency, or label accuracy.

This is worse than most supplement categories. The reason is simple: UK law doesn't require it, and testing costs money. Most vitamin D brands sell on price alone, especially in the D3-only space where the raw ingredient is cheap. Certification adds cost that budget brands won't absorb.

What does this mean for you? Without third-party testing, you're trusting the manufacturer's label claims. A 2021 study in Nutrients found that vitamin D supplements varied from 52% to 135% of their labelled dose. That's a problem if you're relying on a specific daily intake.

Among the 35 products we scored, the top performers are all from brands with strong manufacturing track records: NOW Foods D3 5000 IU and Thorne Vitamin D + K2 both score 87/100 overall. Thorne holds the highest certification score in the category at 85/100. If independent testing matters to you, that's the product to look at.

Do you need vitamin K2 with high-dose vitamin D?

Probably yes at high doses, and our data backs the pairing. Thorne Vitamin D + K2 Liquid is the only D3+K2 combo product in our 35-product database that scores 87/100 overall, matching the top-ranked D3-only options from NOW Foods. It also holds the highest certification score in the category at 85/100.

Here's the science behind it. Vitamin D increases calcium absorption from food. Vitamin K2 activates proteins that direct that calcium into bones and teeth, keeping it out of your arteries and soft tissue. At standard doses (1000-2000 IU daily), most people get enough K2 from diet to handle the extra calcium. At 4000-5000 IU daily, the calcium load increases enough that K2 becomes a more serious consideration.

The Endocrine Society doesn't yet include K2 in its vitamin D guidelines. But a growing body of research, including a 2019 meta-analysis in International Journal of Molecular Sciences, shows the D3+K2 combination improves bone mineral density more than D3 alone.

If you eat K2-rich foods regularly (natto, hard cheese, egg yolks, chicken liver), a standalone D3 product like NOW Foods D3 5000 IU 360 Softgels (87/100) is a solid choice. If your diet is low in K2, or you're taking 4000+ IU of D3 daily, Thorne D + K2 covers both bases in one product.
