Vitamin D3 4000iu & Vitamin K2 100ug MK7 | 400 Vegetarian Tablets - 1 Year Supply | Cholecalciferol & Menaquinone | Made in The UK

After researching the best way to support my immune system and bone health year-round, I decided to try this Vitamin D3 and K2 combo — and I’m genuinely impressed with the results so far. 💊 Potent & Balanced Formula Each tablet delivers 4000 IU of Vitamin D3 (Cholecalciferol), which is a high-strength dose perfect for those living in the UK, especially during the darker months. The addition of 100µg of Vitamin K2 (MK-7, Menaquinone) is crucial — it helps the D3 direct calcium to the bones rather than the arteries. A smart, synergistic pairing! 🌱 Vegetarian-Friendly & Easy to Take The tablets are small and smooth, making them easy to swallow with no aftertaste. As someone following a vegetarian diet, it's a relief that they’re free from animal gelatin or unnecessary fillers. Also: no artificial colours, preservatives, or nasties. 🇬🇧 Made in the UK & High Quality It’s manufactured in the UK under GMP standards, which gives me extra confidence in the quality and traceability of the ingredients. A lot of overseas supplements can be hit-or-miss, but this one feels clean and reliable. 📦 Value for Money 400 tablets for a 1-year supply (or more if you take it every other day in summer) is excellent value. Compared to buying separate D3 and K2 supplements, this is more cost-effective and convenient. ✅ Pros: High-strength D3 with the right form of K2 (MK-7) Great for immune system, bone strength, and mood UK-made with vegetarian-friendly ingredients Massive 400-tablet bottle – no monthly refills!

I’m very happy with this product. The combination of Vitamin D3 4000 IU and Vitamin K2 (MK7) is excellent and feels high quality. The capsule is about the size of a pea, so it’s very easy to swallow. I’ve had no side effects and feel confident taking it daily. I would definitely recommend it.

The tablets are tiny and easy to swallow, which is a big plus for daily use. I’ve been taking them regularly, and while it’s hard to tell exactly how “strong” vitamin D and K supplements are without blood tests, they seem decent quality. No side effects, no odd taste, and the year’s supply make it an excellent value for money. If you’re consistent, this should cover your daily needs well.

Good quality and well priced.

Great size, more or less a supply. Easy to swallow and digest. Great price for combined supplemental vitamins

Good products and good customer service

Great price great product. Great for adding vital vitamins to your daily intake. D3 at this level needs the K2 MK7 to reduce calcium build up in the bloodstream. Always use this type.

I had been taking iPerk 4,000IU Vitamin D3 (Cholecalciferol) with 100 micrograms Vit K2 (ensure calcium diverted to bones, not soft tissue) since around Sep 2023, initially 1/day, then 2/day (8,000IU/day) to aim for a target blood storage (Calcifediol) of 150 nmol/L --- actually reaching 120 nmol/L. Vitamins A D E and K are fat-soluble, and will not be absorbed unless taken with fatty food (I add a small spoonful of yogurt). D3 must be processed by the liver to produce the blood-storage Calcifediol form, and the liver takes 2--3 weeks to process --- so it takes several weeks to achieve a constant blood-level. Calcifediol is absorbed (some say "trapped") in body fat, so those well-endowed need a higher dose to achieve a target blood-level. The potential variability in absorption, liver-function, and body-storage implies results should be assessed using blood-tests giving a numerical result. Thus, I knew the iPerk was working. Sadly, iPerk seem to have discontinued supply. EVO seem to offer similar dosage at very reasonable cost; so I purchased two 400-tablet jars (delivered 31 Jan 25) for (over) a year's supply. However, some reviews claim their "400 tablet" jars contained only 180 tablets. Needs checking: results may be useful to others. My two jars had slightly different weights, at 78.15g and 78.80g. I decided to check the content of the lighter jar. Tablets were small at around 6.1mm diameter. I weighed 1, 2, 4, 10, 20, and 40 tablets --- yielding 0.14, 0.29, 0.57, 1.44, 2.90, and 5.79g, implying consistent weight per tablet (ie counted correctly!) and averaging 0.14475g per tablet. All the tablets in the jar weighed 57.56g, implying 397.7 tablets--- confirming the nominal 400 tablets. The empty jar and it's lid weighed 20.00g, while the removed internal and external seals added 0.34g. Thus the tablets themselves (57.5g) comprised most of the sealed-jar weight (78.15g), so it should be easy to detect an incorrect 180 tablets if we assume the jars are unchanged. My jars appear to be as expected. I have seen reviews --- for various D3 products --- implying tablets were (suspiciously?) small, and note occasional "confusion" between 4,000IU and 100 microgram. Note 4,000IU of D3 _does_ weigh 100 microgram; which together with 100 micrograms of K2 implies active ingredients of 0.0002g/tablet. This is a small fraction of the 0.14g tablet weight, so "small" tablets are not a cause for suspicion. Indeed, there is a strong case for minimising additional "fillers", although there are practical limits to handling very small tablets. All this is irrelevant if the tablets fail to include the claimed vitamins. After a few months I plan further blood-tests, and hope to update this review with confirmation they "actually work" in maintaining Calcifediol blood-storage. For the present I give three stars for value for money, and for what appears to be an excellent product --- hopefully to be raised to five stars in a few months provided blood-tests confirm efficacy.
