Best Vitamin D3 and K2 Supplements We’ve Found in the UK

If you're interested in supplementation, then you should already be well aware of how powerful the combination of vitamin D3 and K2 (usually found in veg and fermented foods) is. They are a super couple which are significantly less effective without each other.

When taking Vitamin D3, vitamin K2 ensures that calcium is absorbed into the bone mass, often taking the calcium found in the blood which can cause arterial calcification (one of the leading causes of heart disease). Both together ensure healthy bones and a healthy heart - plus the added bonus of a healthy immune system (D3) and normal blood clotting (K2).

One should not come without the other. So, if you're thinking about your bones or your heart health, then we've put together a list of what we believe is the best D3 and K2 Supplements that you can buy in the UK.

Life Essentials

One of my favourite supplements right now is this D3, K2 and vitamin C supplement from Life Essentials. This has been my saviour this coming winter.

Each capsule contains 5000iu of D3 (5000% NRV), 100mxg of K2 MK7 (133% NRV) and 100ms of vitamin C (125% NRV). Each capsule is more than enough as a super immune system booster, strengthens your bones and makes me feel great. I have been recently putting the powder into my morning Super greens.

The bag has 60 capsules which is enough for 2 months' worth of immune support, for under £20 is a steal.

Your Zooki

By far, the best D3 and K2 supplement is by Your Zooki. They always produce an exceptional quality supplement for those who don't mind spending a little bit more for their health.

The Zooki supplements come in a little pouch which provides a daily Liposomol dose of Vitamin D3 and K2 together. The Liposomal technology increases the bioavailability and effectiveness of the supplement overall too.

It is possible to buy the Zooki supplement range (including vitamin C ) from Holland & Barrett but some stores don't stock all of them, so it is best to get a month's supply on Amazon.

BetterYou (Holland & Barrett)

One of the best places to grab a vitamin D3 and K2 supplement is in Holland & Barrett; mainly because they have a big selection but also because it is so easy to grab one while you're in town.

This one here is from BetterYou. It is a spray that gives you a healthy daily dose of both vitamin K2 and D3, in an easy-to-take spray. It has a refreshing peppermint flavour as well and a perfect size to keep in your pocket.

This is a great alternative if you're not a fan of taking capsules or you find it difficult to swallow large loads.

The best place to pick up the BetterYou spray is from one of their stores, but you can read the full product description on their website here:

Natures Best (Holland & Barrett)

Natures Best is another brand you'll find in Holland & Barrett stores across the country.

They offer soft cell vitamin D3 and K2 supplements that we rate highly. While they would not be our first choice, they are very good value for money and easy to grab if you're in the store.

The vitamins seem to come from natural extracts, rather than a synthetic mix of the two vitamins. This is a huge selling point if you want to ensure you're getting a completely natural source of both vitamins (without needing to eat 3kg of broccoli).

For more information about the product, you can grab them in-store or via their website here:

Project Nutrition

While the product looks great, it is the company that we like with Project Nutrition. Not only are they part of the '1% of the planet' organisation, they seem to also be dedicatied to keeping their products free from added nasties and allergens.

Each capsule here contains 100mgs of both Vitamin D3 and K2, which is way more than enough for your body to absorb. It will be a very potent supplement and for £20, keep you strong for an entire year. 365 capsules for that money is great.

So, if you want to keep your body supplied for a yea, with one of the best K2 & D3 supplements in the UK, grab them here:

Prowise (Superdrug)

If you just so happen to be passing by a Superdrug, then you can easily pick up the Prowise D3 and K2 supplement, which we think is one of the best across the UK. For the price that you pay, and the size of dose you're getting, this is a very good value for money product. The only consideration that we have is that the supplement does contain an anti caking agent and fillers.

Usually we try to avoid products with these ingredients, but the price here makes them good enough to reccommend if you're on a budget.
