FAQs About Thorne Research Vitamin D-1,000 Capsules

Q: How much vitamin D do you get per capsule? A: Each capsule gives you 1,000 IU, or 25 mcg, of vitamin D3. That equals 125% of the daily value.

Q: Should I take this with food? A: Yeah, ideally take it with a meal. Vitamin D3 is fat-soluble, so it generally absorbs better with some fat.

Q: Does this use D2 or D3? A: D3. The form is cholecalciferol, which is the one most people look for in a daily vitamin D supplement.

Q: How many capsules should I take per day? A: The suggested use is one to three capsules daily. I’d start with one a day unless your practitioner told you to take more.

Q: Is this one vegan? A: Yes, the capsule is hypromellose, which is plant-derived cellulose. If you want to be extra sure, it’s still worth checking with the brand about every raw material source.

Q: My doctor said to be careful with vitamin D. Who should check before taking this? A: If you're pregnant, nursing, taking medications, or have a medical condition, check with your doctor first. I’d be extra careful if you’ve had high calcium levels or kidney issues.

Q: Why does it have vitamin E in it? A: It’s a tiny added ingredient, listed as d-alpha-tocopheryl. Usually that’s there to help protect the formula, not to give you any meaningful amount of vitamin E.
