Biotin Can Improve Your Hair, Nails, Skin, and Health!

Disclaimer: Results are not guaranteed*** and may vary from person to person***.

Biotin DeficiencyLast year, a friend of mine began to notice visible changes in her appearance—her once thick, lustrous hair began to thin out in certain areas; her nails became chipped and brittle; and she complained of dry skin.

She blamed it on stress and improper eating habits—and she may have had a point. Brittle nails, thinning hair, and lackluster skin can all be indicators that your body is lacking certain nutritional value, particularly related to iron, omega-3 fatty acids, and vitamin B.

In my friend’s case, I recommended she drink more water and start taking biotin supplements, which is a significant part of the B complex group of vitamins. Within six months, she saw vast improvements in her overall appearance, in particular with hair growth.

The Health Benefits of Biotin

Biotin, also known as vitamin H, is a water-soluble B complex vitamin and it is extremely beneficial in metabolizing protein and fats. Including biotin as part of your regimen plays a significant role in the human body, especially with keeping the skin, digestive system, metabolism, and cells functioning at a high level:

1. Benefits skin, hair, and nails: Biotin can help improve keratin production. Keratin is the protein that forms the nails, skin, and hair—so including the recommended levels of biotin in your diet can be beneficial to your appearance. One study illustrated a 25% increase in the thickness of nails when consuming biotin supplements. A similar study stated that there was a significant improvement in nail strength in 91% of participants who took the recommended levels of biotin for their age group.

2. Healthy pregnancy: Biotin deficiency is most common among pregnant women—the deficiency has even been known to raise the risk of abnormal fetus development. Folic acid supplements are highly recommended during pregnancy and post-pregnancy. Pregnant women who take 30 micrograms (mcg) of biotin each day, along with folic acid, will decrease their risk of biotin deficiency.

3. Beneficial for diabetes patients: Consuming adequate levels of biotin, along with chromium, has been shown to effectively decrease the blood sugar level in type-1 and type-2 diabetes patients. Consuming biotin on its own can decrease insulin resistance for those with type-2 diabetes.

In a 2006 study published in the journal Diabetes Technology and Therapeutics, researchers monitored the blood sugar levels in 43 diabetes patients who consumed recommended levels of chromium with biotin. After four weeks, their blood sugar levels improved. The combination of the two supplements also lowered the participants’ cholesterol levels.

Biotin Deficiency and Symptoms

Signs of a biotin deficiency include brittle nails, thinning hair, and lackluster skin; more serious symptoms can include depression, listlessness, hallucinations, and even tingling of the arms and legs. Some studies have linked smoking and biotin deficiency. Biotin deficiencies can be common for those who fall in one of the following categories:

  • Someone who drinks excessively
  • A person who consumes large amounts of raw eggs in their diet (the protein in raw eggs actually blocks the absorption of biotin)
  • Someone who suffers from biotinidase, a genetic biotin deficiency

Biotin Dosage

Some might say, “I’ll take a ton of biotin supplements so my hair and nails can grow!” No, that’s not how it works. Consuming more supplements than you’re supposed to can have adverse effects; taking more than the recommended dosage of biotin could lead to skin rashes and high blood sugar. The amount of biotin a person should consume is dependent on two main factors: the age of the person and the state of the person’s health. Here are some general guidelines to follow:

  • For infants up to 12 months old, the proper intake of biotin is 7 mcg
  • For children from one to three years of age, the proper intake is 8 mcg
  • For children from four to eight years of age, the proper intake is 12 mcg
  • For children from nine to 13 years of age, the proper intake is 20 mcg
  • For teenagers from 14 to 18 years of age, the proper intake is 25 mcg
  • For adults and pregnant women 18 years of age or older, the proper intake is 30 mcg
  • For women 18 years of age or older who are breastfeeding, the proper intake is 25 mcg

Biotin-Rich Foods

If you’re not big on taking supplements, here are some of the best biotin-rich foods that you should incorporate into your diet:

1. Carrots: You may have heard that by eating carrots, you will be able to significantly improve your eyesight. It’s true! Carrots contain high volumes of biotin, along with beta-carotene, which is the nutrient that helps with eyesight.

2. Chard: This leafy green is chalk full of biotin and makes a delicious addition to stir fry.

3. Berries and fruits: Strawberries and raspberries can provide you with high levels of biotin—you will also gain the antioxidants that are necessary for your body to function at a healthy rate. Refrain from buying them in bulk, and whenever possible, buy organic.

4. Vegetables: For maximum biotin intake, focus on consuming onions, cucumbers, and cauliflower.

5. Nuts: Nuts are not only packed with biotin, but they are also rich in protein and other nutrients.

Consult your doctor before taking any new supplements or starting a new meal plan.
