Terranova Vitamin D3 2000 IU with Vitamin K2 100 mcg is a combined fat-soluble vitamin supplement designed to support bone mineralisation, calcium regulation, and immune function. Vitamin D3 — the form the body produces in response to sunlight — is the preferred supplemental form over D2, as it raises and maintains circulating 25(OH)D levels more effectively. Vitamin K2, specifically used to direct calcium toward bone tissue and away from soft tissue such as arterial walls, works alongside D3 in a complementary physiological pathway: D3 increases calcium absorption; K2 helps ensure it is deposited in the right places.
This pairing is particularly relevant for people living in northern latitudes like the UK, where sunlight is insufficient for adequate D3 synthesis for much of the year. It also suits those with confirmed low vitamin D on a blood panel, older adults concerned about bone density, and anyone who takes D3 alone and wants the added K2 for balanced calcium metabolism.
Terranova is a brand known for its clean, additive-minimal formulations. As with any fat-soluble vitamin supplement, taking it alongside a meal containing fat supports optimal absorption. The 2000 IU dose sits within the range broadly considered appropriate for daily maintenance in adults, though individuals with significant deficiency may be advised by a clinician to use a higher therapeutic dose first.
Vitamin D3 2000IU, Vitamin K2 100mcg

Take one capsule daily with a meal that contains some fat, as both D3 and K2 are fat-soluble and absorption is improved in the presence of dietary fat. Follow the dosage guidance on the packaging and consult a clinician if you have a confirmed deficiency, as a higher therapeutic dose may be recommended before moving to maintenance.
Vitamin D3 increases the absorption of calcium from the gut. Vitamin K2 activates proteins — particularly osteocalcin and matrix Gla-protein — that direct calcium into bone and may help prevent it accumulating in soft tissues like blood vessels. The two vitamins work in the same calcium-regulation pathway, which is why combining them is considered more complete than D3 alone.
The most reliable way is a blood test measuring serum 25(OH)D. In the UK, routine deficiency is common, particularly from October to March. If you have not had your levels checked, a simple blood panel — available through your GP or a private clinic — will tell you whether you need a maintenance dose, a higher therapeutic dose, or nothing at all.
Vitamin K2 can interact with anticoagulant medications, including warfarin, by influencing clotting factor activity. If you are on any anticoagulant, speak to your GP or prescribing clinician before starting this supplement — do not self-prescribe.
Vitamin D is a slow-acting nutrient. Raising serum levels to an optimal range typically takes several weeks of consistent supplementation, and the benefits — improved bone density, immune resilience — are not acutely felt. A follow-up blood test after 10–12 weeks of supplementation is the practical way to confirm your levels have responded.
Possibly, but check whether your multivitamin already contains D3 and K2, and at what amounts. Combining supplements containing fat-soluble vitamins can lead to unintended high intake over time. Check the packaging of both products and, if uncertain, ask a clinician or pharmacist to review your full supplement stack.

Overall Sentiment

Been through a few different brands over the years and this one genuinely feels like a step up. No fillers, no unnecessary extras. I take it with breakfast — always with something containing a bit of fat — and my last blood panel showed D levels in a really good range for the first time in ages. The K2 pairing was the main reason I picked this one and I'm glad I did.

Does exactly what it says. Take one daily with lunch, no complaints.

Living in Manchester, I basically have zero sun exposure from October to April. Started taking this after my GP flagged low vitamin D on a routine blood test. Love that the K2 is already included — saves me buying two separate products. Clean formula, easy to swallow.

No issues with the formula itself — I specifically wanted D3 paired with K2 after reading up on calcium metabolism, and this ticks all the boxes. My only gripe is that the capsules are noticeably bigger than others I've used, which makes them slightly awkward to swallow first thing in the morning. Minor thing but worth noting if that's a concern for you.

Switched to this after a friend who works in nutrition told me not to bother with D3 without K2. Makes sense once you understand the reasoning. Ordered twice now and will keep buying.

I'd been taking plain D3 for a couple of years but wanted to add K2 for bone health. Found this and it simplified my whole morning stack considerably. The fact that there's barely anything unnecessary in the ingredients list was the deciding factor over a couple of other options I was considering.
