Vitamin A is important for eye health immunity and maintenance of hair skin teeth and bone but over 25 000 IU per day may become toxic and lead to a condition known as hypervitaminosis. This condition leads to temporary hair loss and other medical conditions especially in women. Safe dosage of vitamin A is 4 000 to 5 000 IU per day.
Too much zinc consumption for hair loss because it interferes with the body’s ability to absorb copper iron magnesium and manganese which are all important for healthy hair. Zinc can be toxic when taken in excess of 60 milligrams daily. Stick closer to the recommended daily dose of 11 milligrams but higher doses below 60 mg can increase hair growth.
Hormones commonly found in oral contraceptives and hormone replacement therapy (HRT) has been shown to speed up hair growth does but faster hair growth hair reaches its resting phase and fall out faster than normal. As a result people who take contraceptives or HRT drugs experience hair loss. Normally the body adjusts to the hormones after three to four months and hair loss decreases.
prescription medications alcohol and drugs change the way supplements are absorbed and may require you to take different doses. Likewise pregnant and lactating women need slightly higher doses of vitamins and minerals than normal and women who have just given birth may be necessary to adjust the dose as well. If any of these conditions apply to you ask a doctor or nutritionist before taking supplements.

Fortunately some companies voluntarily follow the standards that FDA establishes medicine. Research vitamin manufacturers before buying supplements so you can be sure of is coming from a trusted source.
