Vitamin D and its Nootropic Properties
Vitamin D, also known as calciferol, is a fat-soluble vitamin that is naturally present in very few foods, added to others, and available as a dietary supplement. It is also produced endogenously when ultraviolet rays from sunlight strike the skin and trigger vitamin D synthesis. Vitamin D is essential for many processes in the body, including bone health, immune system functioning, and neuromuscular functioning. Recent research has suggested that Vitamin D may also have nootropic properties, which can improve cognitive functioning.

The recommended daily allowance (RDA) for Vitamin D is 600 IU (15 mcg) for adults up to age 70, and 800 IU (20 mcg) for adults over 70. However, some experts suggest that the RDA should be higher, up to 4,000 IU (100 mcg) per day. It is important to speak to a healthcare professional before taking any supplements to determine the right dosage for you.
Vitamin D was first discovered in the early 1900s, when researchers noticed that cod liver oil could prevent rickets, a bone-weakening disease. It was later discovered that the active ingredient in cod liver oil was Vitamin D. Since then, Vitamin D has been studied extensively and is now known to be essential for many processes in the body. More recently, research has suggested that Vitamin D may also have nootropic properties, which can improve cognitive functioning.
