FAQs About Thorne Research Vitamin D-5,000 NSF Certified Capsules

Q: How much vitamin D is in each capsule? A: Each capsule contains 125 mcg, or 5,000 IU, of vitamin D3. It's a higher-potency dose, so people often use it when their practitioner wants them taking more than a basic maintenance amount.

Q: Should I take this every day? A: Usually, yes. One capsule daily is the standard use. Since it's 5,000 IU, I'd stick with that unless your doctor told you to do something else.

Q: Does this use D2 or D3? A: D3. That's the form most people usually mean when they're looking for vitamin D support for bones, teeth, muscles, and immune health.

Q: Can I take this with food, or does it matter? A: Yes, you can take it with food, and I'd usually suggest that. Vitamin D is fat-soluble, so taking it with a meal makes sense.

Q: I've heard 5,000 IU is a lot. Is that too much? A: Maybe. It depends on your labs and what your doctor wants for you. For some people, it's a reasonable dose, but if you're already taking a multivitamin or a calcium product with vitamin D, I'd add up your total first.

Q: Are there any ingredients besides vitamin D I should know about? A: Yes, it's pretty simple. The capsule is hypromellose, and the other ingredients are microcrystalline cellulose, leucine, silicon dioxide, and a small amount of vitamin E as d-alpha-tocopheryl.

Q: Is there anything I should be careful with before starting this one? A: Yes. Check with your doctor first if you're pregnant, nursing, taking medications, or have a medical condition. I'd also be extra careful if you've ever had high calcium levels or issues from too much vitamin D.
