Biotin is a water-soluble vitamin of the vitamin B family, also known as vitamin B7 or H. Your body needs it to process nutrients into energy and maintain a healthy nervous system. It also plays an important role in healthy hair, skin, and nails. Hair loss, brittle nails, and rashes are signs of biotin deficiency, which can occur due to genetics, poor diet, alcoholism, or pregnancy.
Cuticles oils can also help you to maintain healthy nails, browse our selection!
Biotin deficit is rare as we consume enough through our diet, from biotin-rich sources such as milk, some animal based foods, certain vegetables, seeds, and nuts. Biotin is critical for the production of protein, which leads to the development of strong, healthy hair and nails. Small studies have shown that biotin supplements can help strengthen nails and maintain healthy hair, though evidence to support this is limited.
If you don't get enough biotin through your diet or want to increase your dosage for luscious locks, supplements may be an option. Trichologists (hair specialists) and dermatologists may recommend biotin for hair maintenance and for patients suffering from hair loss. The good news is that biotin, even in high doses, appear to be harmless. However, always check with your doctor before consuming any supplements.
Adequate Intake of biotin as proposed by the European Food Safety Authority for adults and pregnant women is 40 mcg a day. Lactating women need 45 mcg a day to compensate for biotin loss through breast milk. For infants, the suggested dosage is 6 mcg a day, for children and adolescents, it is between 20 mcg to 35 mcg a day.
Knowing how much biotin you are taking is important in order for it to work, as well as being mindful of any potential negative effects. Nevertheless, biotin supplements side effects are generally rare, and there is no upper limit because it is water-soluble, which means the body only stores what it needs, and the rest is excreted through urine.
Because of this, it is normal to find supplements with up to 10,000 mcg of biotin as these levels ensures that your body fully absorbs the amount it needs. However, one thing to note is that consuming too much biotin can interfere with certain medical lab test results, which is why it is important to always consult your doctor before you begin a biotin supplement.
Other useful ingredients may be included in certain biotin supplements, whether it is to boost absorption, effectiveness or to offer additional nutritional support. Coconut oil regularly features in combination with biotin for better nutrient absorption.
In many hair loss therapies, inositol is coupled with choline to form phospholipids, which are necessary for the formation of healthy hair follicles. Zinc and selenium are two other common ingredients found in hair growth supplements as they play a key role in hair tissue growth and repair. Zinc also helps to keep the oil glands around the hair follicles in check, so that it functions properly to facilitate hair growth.
Try out hair growth products to further assist your hair goals.
Meanwhile, other essential vitamins such as vitamins A, C, D, and E, as well as vitamin B complexes are frequently added to provide overall nutritional support that your body needs daily for normal and healthy body functions.
Capsules, for example, have an outer shell that can be made from gelatine, a protein derived from animal bones, skin, tendons, and ligaments, hence they are not suitable for vegetarians or vegans. If you are on a meat-free diet, always check the ingredients to see whether they include any animal products, or only take biotin supplements that are certified vegan or vegetarian to be completely sure.

Supplements taken orally, such as tablets and capsules may contain traces of gluten. A thorough examination of the ingredient list can help you to eliminate any potential dangers. But the best way to ensure that you avoid any allergic reactions is to opt for biotin supplements that specify they are gluten-free.

Biotin pills can be taken at any time of day. It should, however, always be taken on an empty stomach, at least one hour before or two hours after meals. But if you often experience stomach problems, it is advisable to take it with food to prevent worsening your condition.
There is currently not enough evidence to support that biotin supplements can cause acne.
