Our body requires many vitamins and minerals to thrive and produce healthy skin, nails, and hair. Folic acid supports basic cell production in the body which directly influences our ability to grow healthy hair.

What is Folic Acid?

Folic acid is a B vitamin that can be taken as a supplement or be found naturally in green, leafy vegetables, fruits, beans, nuts and some bread and cereal products.


Folic acid is responsible for making new cells in the body. Since hair growth depends on regular cell regeneration in the follicle, a steady supply of folic acid is needed to support this process.


Folic acid, along with a healthy, well balanced diet and other B vitamins, prevents hair thinning and loss.

Daily Intake

The recommended daily allowance of folic acid is 400 micrograms daily, and no more than 1,000 micrograms per day, for both men and women.


Rare allergic reactions to folic acid have been observed and include skin rashes, itching and difficulty breathing. Always consult a physician before taking any new vitamin supplement.
