Nioxin Intensive Therapy Recharging Complex may cause side effects if taken in excess amounts based on its key ingredients listed on Folica.com, according to Drugs.com and the American Cancer Society. The ingredients in the supplements that can cause side effects are proteusterone, ascorbic acid and niacinamide.
Proteusterone is made from dioscorea root, a wild yam that is popular among women to treat various conditions related to menopause, notes the American Cancer Society. The proponents of the yam claim it contains natural progesterone that can help women lose weight, increase energy and enhance sex drive. However, excessive doses of the yam can cause nausea, vomiting and diarrhea. It should not be used by women who are pregnant or breastfeeding, and rare reactions such as rashes and asthma can occur.
Ascorbic acid, also known as vitamin C, is used for preventing and treating low levels of the vitamin in the body, explains Drugs.com. In large amounts, it can cause side or lower back pain, diarrhea, dizziness, headache and stomach cramps. Kidney stones can also form if the vitamin is taken in large amounts. It is best to consult a qualified health professional to discuss dosing before supplementation.
Niacinamide is a vitamin B supplement used for preventing and treating low levels of vitamin B3 in the body, states Drugs.com. The vitamin can cause dizziness, lightheadedness or fainting that worsen when taken with alcohol or certain medications. It can also affect blood sugar in diabetic patients and cause other symptoms such as itching, nausea, stomach upset and flushing of the skin.
