Strengthens immunity
Vitamin D3 supports the immune system, particularly vital during the common cold season. It prevents calcium from depositing in bones, strengthening my teeth and reducing sensitivity. I took it for a course, and after testing, my D3 levels rose significantly, improving my health and mood. I suggest taking it with K2 and magnesium to prevent kidney issues. Over six months, my levels increased from 36 to 65. The capsules are small and easy to swallow, with no negative side effects.

Essential vitamin D
Excellent product! It's crucial for everyone. I ordered on 2nd December and received it on 18th December. Vitamin D, or prohormone as it's now called, benefits the entire body, including the immune system, especially during the common cold season. This product from California COLD Nutrition offers a convenient 5000 IU dosage in small capsules, perfect for swallowing difficulties. I highly recommend it to anyone deficient in this vitamin.

Prevents colds
This dosage of vitamin D effectively addresses my deficiency. I take a capsule each morning with vitamin C and zinc. The results are impressive; I hardly catch colds and had a mild bout of COVID without significant symptoms.
