★★★★★ "I won't go back to high street supplements. The difference in quality is something you can actually feel." Susie
Vitamin D3 and K2 Oil gives you the vitamin pair for bones and immunity in the oil they absorb best from, dosed by the drop. Ten drops provide 1000 IU of vitamin D3 and 50mcg of natural vitamin K2, with every drop carrying both in the same ratio. A 100ml bottle holds 147 servings of ten drops.
Benefits of taking vitamin D3 and K2
Vitamin D helps your body absorb calcium, while vitamin K helps keep it in your bones and keeps blood clotting normally. Together they cover how calcium is taken up and where it goes, which is why the two are so often taken as a pair.
- Bones and teeth stay strong, because both vitamins act on calcium.
- Your immune system gets the vitamin D it relies on.
- Muscles keep working as they should.
- Blood clots normally, which is vitamin K's other job.
Who benefits
Vitamin D3 and K2 Oil is most useful for:
- People who want a lower daily amount than the capsules give, set drop by drop.
- Families dosing a child and several adults from one bottle, each at their own amount.
- Anyone who prefers drops to capsules or cannot swallow them.
- Those adjusting their amount to a blood test result with a practitioner.
If you have tested low and want a single high daily amount, Vitamin D3 and K2 Capsules give 2500 IU with 200mcg of K2 in one capsule.
What is in it
Ten drops provide 25mcg of vitamin D3, which is 1000 IU and 500% of the daily reference value. With it comes 50mcg of natural vitamin K2, which is 67%, all in an oil base. Each drop is roughly 100 IU of D3 and 5mcg of K2. Liquid vitamin D3 with K2 and D3 K2 drops are other names for it.
How to take it
Take ten drops a day with food, straight from the dropper, on food or in a drink. The amount scales by the drop, so five drops give 500 IU of D3, ten give 1000 IU and twenty give 2000 IU.
Diet and allergens
The oil is suitable for vegetarians but not for vegans. It is free from gluten, dairy and nuts.
Quality
The oil is made in the UK in a GMP certified cleanroom facility accredited to ISO 9001 and ISO 14001. Every batch is traceable from raw material to finished product. Like every supplement Nutri Tailor stocks, it is practitioner grade and guaranteed additive free.
Common questions
Why choose the oil rather than the capsules?
The oil lets you set the amount drop by drop, with both vitamins in the same ratio in every drop. By contrast the capsules give a fixed 2500 IU of D3 with 200mcg of K2, which suits people who have tested low and want one high daily amount.
How much vitamin D should I take a day?
Take ten drops a day, which gives you 1000 IU of vitamin D3 and 50mcg of K2. Adjust the number of drops on a blood test result and your practitioner's guidance.
When is the best time to take it?
You can take it at any time of day, with a meal. The oil base already carries the vitamins well, while food helps your body use them.
Can I take it with other supplements?
Yes. It pairs well with Magnesium Bisglycinate (Glycinate) Capsules, because your body uses magnesium to regulate the active form of vitamin D.
Can I take too much vitamin D?
Yes, because vitamin D is fat soluble, so keep to the drops you have been advised and get your level tested rather than guessing.
Why is vitamin D paired with K2?
Vitamin D helps your body absorb calcium and vitamin K helps keep bones normal and blood clotting normal, so the pair covers both jobs in one bottle.

Frequently asked questions
Why take Vitamin D3 & K2 Oil?
Vitamin D3 & K2 Oil supports bone health, immune function, and mood regulation.
How much D3 and K2 is in 10 drops, and how long does the bottle last?
Ten drops give you 1000 IU (25mcg) of vitamin D3 and 50mcg of natural vitamin K2 in an oil base. Each drop is roughly 100 IU of D3 and 5mcg of K2, so you can scale the dose up or down. A 100ml bottle is about 147 servings of 10 drops.
When should I take vitamin D?
Take with your largest meal containing fat for best absorption.
Can I take too much vitamin D?
Yes, vitamin D is fat-soluble. Get your levels tested and work with a practitioner to find your optimal dose.
Why is vitamin D paired with K2?
Vitamin D contributes to the normal absorption of calcium and the maintenance of normal bones, and vitamin K contributes to the maintenance of normal bones and normal blood clotting. The pairing covers both of those authorised roles in one capsule.
Why choose the D3 and K2 oil rather than the capsules?
The oil gives 1000 IU of D3 and 50 mcg of K2 in ten drops, and every drop carries both vitamins in the same ratio, so the dose can be set drop by drop. The capsules give 2500 IU of D3 with 200 mcg of K2 in one fixed dose. The oil suits people who want a lower daily amount, who are dosing a child or several family members from one bottle, or who prefer drops to capsules. The capsules suit people who have tested low and want a single high daily dose.
Why drops rather than tablets?
Drops let the amount be adjusted one drop at a time, and they suit anyone who cannot swallow tablets. Tablets need binders and a coating to hold their shape; this liquid contains only the active ingredient and its carrier.
