1. Vitamin A
This includes hair, the fastest growing tissue in the human body. Vitamin A also helps skin glands make an oily substance called sebum. Sweet potatoes, carrots, pumpkins, spinach, and kale are all high in beta-carotene, which is turned into vitamin A. Vitamin A can also be found in animal products such as milk, eggs, and yogurt.
Cod liver oil is a particularly good source.
Vitamin D
Supplementation with vitamin D may not have direct links with hair growth, but having a deficiency may impact hair health. Many of the studies in the review found low levels of vitamin D in people with alopecia areata.
There is also little evidence to suggest that vitamin D can lead to hair regrowth. However, further studies are necessary to confirm this potential link. Getting enough vitamin D The Office of Dietary Supplements recommend that adults get 600 international units (IU) , or 15 micrograms (mcg), of vitamin D per day.
However, many experts agree that this daily recommendation is likely too low to reach optimal blood levels, which most experts agree lies between 30 and 60 nanograms per milliliter (ng/ml) . Vitamin D supplements are available for purchase online, but a person should always check with their doctor before taking any vitamins. That said, vitamin D supplements are relatively safe, and toxicity is extremely rare.
An excessively high dose would be over 50,000 IU or when blood levels of vitamin D are greater than 150 ng/ml . Taking vitamin D with a meal that contains fat will improve the absorption of this vitamin.
