What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium uptake and supports bone health, with roles in immune system function in line with NHS and EFSA guidance.

I am absolutely thrilled with my purchase of the Thorne Vitamin D3 capsules! They are easy to swallow and I've noticed a significant improvement in my energy levels since I started taking them. The fact that they are vegetarian-friendly is a huge plus. I would definitely recommend these to anyone looking to boost their Vitamin D intake.
