Vitamin D cho Autoimmune Conditions

A Bằng chứng Nhiều thử nghiệm lâm sàng lớn liên tục cho thấy những lợi ích đáng kể.

The VITAL trial (25,871 participants over 5 years) demonstrated vitamin D supplementation at 2,000 IU/day may reduce autoimmune disease risk by 22%. This represents one of the largest and longest randomized trials of vitamin D for autoimmune disease prevention.
