- D3 1,000–5,000 IU
- K2 as MK-7
- Capsules or drops
What it’s for
The supplement a pharmacist is most likely to have suggested already. One small capsule, or a drop on the tongue.
What to check in the listing
Strength varies a lot between products, from 1,000 IU to 5,000 IU per capsule, so read the label before comparing prices. K2 should be named as MK-7 rather than just 'K2'. Drops and capsules hold the same thing in different packaging; a blood test is the cheap way to know where you stand.
Supplements are food, not medicine: nothing here treats or prevents anything. If you take any medicine, ask a pharmacist first.
