There’s an old saying that a woman's hair is her crowning glory. But what if that crown is thinning, weak, and lackluster? Biotin (also known as Vitamin H) is a water-soluble vitamin that plays a vital role in maintaining healthy skin, hair, and nails. It is one of the most popular supplements among those looking to improve the appearance of their hair.
In this article, we’ll explore some of the benefits of biotin that go beyond hair care.
What is Biotin?
Biotin is part of the vitamin B complex and is necessary for the production of enzymes that help convert food into energy. It plays a vital role in the body's metabolic processes and is an essential nutrient that the body needs to maintain healthy hair, skin, and nails. The enzyme responsible for keratin production (a protein that makes up hair, skin, and nails) depends on biotin for its proper function.
It is important to note that the human body does not naturally produce biotin. As a result, it must be obtained through diet or supplements. Foods that are high in biotin include eggs, nuts, whole grains, and liver.
Biotin Deficiency
Biotin deficiency can lead to hair loss, brittle nails, and dry skin. In rare cases, severe Vitamin H deficiency can lead to neurological symptoms such as depression, lethargy, and hallucinations. Supplementing with biotin can be beneficial for individuals with dietary restrictions or medical conditions that affect biotin absorption. It is also a reasonable option for anyone who’s not able to meet their daily requirements from diet alone. Biotin supplements are available in various forms, including capsules, gummies, and topical treatments.
What is Biotin Good For?
Biotin has gained immense popularity as a hair growth supplement over the last few years. But does it really work?
Scientific research shows that biotin can positively impact hair growth, making it a promising treatment for hair loss. Specific studies have demonstrated that biotin supplementation improves hair thickness and volume in people with hair loss, alopecia, and other related conditions.
Other Biotin Benefits
Beyond promoting hair growth, biotin offers a wide range of other health benefits:
-
Metabolic Function - plays a crucial role in the metabolism of carbohydrates, fats, and amino acids. Vitamin B7 helps convert food into energy and is essential for the proper functioning of the body's metabolic processes. It also helps maintain healthy blood sugar levels by regulating insulin production.
Skin, Nail, and Overall Appearance - biotin supports the production of keratin, the main structural protein found in hair, skin, and nails. It’s no wonder that deficiencies have been known to lead to a wide range of skin conditions (e.g. acne, rashes, and dryness). -
Cardiovascular Health - helps regulate cholesterol levels in the body, which can in turn lower the risk of heart disease. Biotin is also known to help maintain healthy blood pressure and improve blood flow, leading to better overall cardiovascular health.
-
Brain Function and Cognitive Health - improves brain function and cognitive health. It helps in the production of neurotransmitters that are essential for the proper functioning of the brain. Lower than adequate levels of biotin in the body have been linked to depression and cognitive decline in older adults.
-
Thyroid and Adrenal Function - regulates thyroid and adrenal gland function. This in turn impacts metabolism, energy levels, and stress responses.
-
Tissue and Muscle Growth and Repair - biotin is necessary for the growth and repair of tissues and muscles in the body.
Biotin vs Other Hair Growth Supplements
Compared to other hair growth supplements and treatments, biotin has several advantages.
-
Targeted benefits - specifically formulated to promote hair growth and improve hair health.
-
Easily available - widely available in pharmacies, health food stores, and online retailers. You can easily find a high-quality biotin supplement without having to search extensively.
-
Affordable - generally affordable, and you can find a good quality supplement without breaking the bank.
-
Safe – biotin is a water-soluble vitamin, which means that it is not stored in the body and is eliminated through urine. It is thus considered to be safe and has minimal risk of toxicity or overdose.
Clinically proven – there is scientific evidence to support the effectiveness of biotin supplements. Multiple clinical studies have shown that biotin supplements can promote hair growth and improve hair health. -
Easy to use - biotin supplements come in the form of capsules or tablets that are easy to swallow and can be taken at any time of the day.
-
No side effects - biotin is a natural vitamin that is already present in the body, so it does not have any negative side effects or risks associated with its use.
Biotin Dosage
There’s no standard dosage of biotin for hair growth, but experts generally recommend that adults and teenagers take between 30 and 100 micrograms (mcg) per day, but higher dosages have been used for many scientific studies and are generally considered safe. Keep in mind that taking too much biotin can be harmful, so it's best to follow instructions carefully and consult with a healthcare provider if you have any underlying conditions or concerns.
Is Biotin for Everyone?
Biotin is based on a natural vitamin that’s already available through everyday food choices. It is considered to be generally safe for most people. However, you should contact your healthcare provider before taking biotin supplements if you:
-
Are pregnant – high doses of biotin may interfere with certain laboratory tests that are used to screen for neural tube defects in fetuses. For this reason, pregnant women should avoid biotin supplements unless recommended by their healthcare provider.
-
Are breastfeeding - while biotin is important for healthy hair, skin, and nails, there is limited research on the safety of biotin supplements during breastfeeding. Breastfeeding women should thus avoid biotin supplements unless recommended by a doctor.
-
Are taking certain medications – supplementation with biotin may interfere with certain medications, including anticonvulsants, antibiotics, and cholesterol-lowering drugs. If you are taking any of these, make sure to get approval from your doctor first.
-
Suffer from certain medical conditions – individuals who are suffering from conditions such as kidney disease may be at a higher risk of biotin toxicity and should avoid biotin supplementation unless otherwise recommended by a qualified medical professional.
-
Are allergic to biotin – though rare, some people may experience allergic reactions to biotin supplements. Make sure to avoid biotin supplements if you have a history of allergic reactions to Vitamin B7.
