Best Vitamin Supplements

High-potency vitamin D3 supplement providing 5000 IU per serving to support optimal blood levels. Essential for immune function, bone health, and mood regulation. One of the most widely recommended supplements among longevity researchers due to widespread deficiency.

High-quality vitamin C supplement supporting immune function, collagen synthesis, and antioxidant defense. Essential for tissue repair and iron absorption. Liposomal forms offer enhanced bioavailability compared to standard ascorbic acid.

Bioactive methylfolate (5-MTHF), the body-ready form of folate critical for DNA synthesis, repair, and methylation. Unlike synthetic folic acid, methylfolate bypasses the MTHFR enzyme conversion step, making it effective for individuals with common MTHFR gene variants. Supports homocysteine metabolism, neural tube development, and red blood cell formation.

Vitamin K2 in the MK-7 form supports proper calcium metabolism, directing calcium into bones and teeth while preventing arterial calcification. Works synergistically with vitamin D3 to optimize bone mineral density and cardiovascular health. Essential for activating proteins involved in blood coagulation and vascular protection.
