Detailed score breakdown and key findings from our analysis of 50 reviews across 1 source.
Pros
- +Neutral to mildly oily taste — reviewers consistently report children take it without resistance
- +Single-drop = 400 IU dose, matching AAP and WHO guidance for infants exactly
- +10ml bottle lasts a full winter season or longer at 1 drop/day — multiple reviewers flag this as economical
- +Alcohol-free with a short, clean ingredient list — important for a product used from birth
- +Cholecalciferol in coconut oil base: correct form of D3, correct carrier for fat-soluble absorption
Cons
- -Not third-party tested — for a product used from birth, the absence of independent verification is a real gap
- -Dropper mechanism is fiddly; one reviewer noted drops don't flow immediately, making precise infant dosing harder than it should be
- -Some reviewers describe the taste as oil-like rather than neutral — a minority complaint, but consistent enough to flag
- -No dose flexibility above 400 IU — parents whose paediatrician recommends higher doses for older children will need a different product

What the Data Says About Vitamin D
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.
