Best biotin for hair
Biotin supplements can have very different formulations: some contain only vitamin B7, while others combine this micronutrient with vitamins, minerals, plant extracts or ingredients intended to support the wellbeing of hair, skin and nails.
Here are six Tsunami Nutrition products that include biotin in their formulations.
1. Biotin 90 Tablets – TN Naturals
Biotin 90 Tablets by TN Naturals is a food supplement with a simple formulation, designed for those who want to supplement their diet with biotin without combining it with other active ingredients.
Each tablet contains 10,000 µg of biotin, a high concentration compared with the amounts normally obtained through food and daily reference values.
Biotin contributes to the maintenance of normal hair and skin, as well as participating in normal energy metabolism. Its presence as the sole active ingredient makes it possible to know precisely how much vitamin B7 each tablet provides.
It is an option worth considering, particularly for those looking for a product containing a single micronutrient in a clearly defined amount. However, it is important to remember that a high intake does not automatically provide greater benefits for hair.
- Biotin per tablet: 10,000 µg.
- Format: 90 tablets.
- Formulation: high-dose biotin.
- Features: vegan, gluten-free and lactose-free.
2. +Capelli 60 Tablets – TN Pharma
+Capelli by TN Pharma is a food supplement specifically formulated for hair health, combining vitamins, minerals, amino acids and plant extracts.
The formulation includes Annurtrofil®, an extract of annurca apple, L-methionine, vitamin E, bamboo extract, niacinamide, zinc, spermidine, beta-carotene, copper, selenium and biotin.
Biotin is present at 100 µg per daily serving, equivalent to two tablets. The formula also contains zinc and selenium, which contribute to the maintenance of normal hair, while copper contributes to normal hair and skin pigmentation.
The presence of Annurtrofil®, a patented ingredient derived from annurca apple, further distinguishes this formulation, which combines several components in a single product.
+Capelli is therefore an option to consider for those looking for a supplement specifically designed to support hair health rather than a simple biotin supplement.
- Biotin per daily serving: 100 µg.
- Other ingredients: Annurtrofil®, L-methionine, vitamin E, bamboo, niacinamide, zinc, spermidine, beta-carotene, copper and selenium.
- Format: 60 tablets.
- Recommended use: 2 tablets per day.
- Features: vegan, gluten-free and lactose-free.
3. Skin-Nails 30 Sachets – TN Pharma
Skin-Nails by TN Pharma is a food supplement in sachets that combines biotin, hydrolysed collagen, keratin, plant extracts and other micronutrients.
Each sachet provides 100 µg of biotin, together with 2,500 mg of Verisol® hydrolysed collagen, 500 mg of Kera-Diet® hydrolysed keratin, 500 mg of horsetail extract, 200 mg of Phlebodium extract and 50 mg of hyaluronic acid.
The formulation also includes vitamin C, zinc and copper. Vitamin C contributes to normal collagen formation for the normal function of the skin, while zinc and selenium are nutrients involved in the maintenance of normal hair.
The presence of hydrolysed keratin and collagen makes this product a more comprehensive formulation than supplements containing biotin alone.
It is an option to consider for those looking for a supplement intended to support the wellbeing of hair, skin and nails at the same time.
- Biotin per sachet: 100 µg.
- Other ingredients: Verisol® collagen, Kera-Diet® keratin, horsetail, Phlebodium, hyaluronic acid, vitamin C, zinc and copper.
- Format: 30 sachets.
- Recommended use: dissolve one sachet in 150 ml of water and take once a day.
- Features: gluten-free and lactose-free.
4. Metabolic-GL – TN Pharma
Metabolic-GL by TN Pharma is a food supplement formulated primarily to support metabolism and manage feelings of satiety. It is therefore not designed specifically for hair, but it also contains biotin.
Each tablet provides 50 µg of biotin, equivalent to 100% of the Nutrient Reference Value, together with 25 µg of vitamin D.
The formula also includes the METAGL+ plant extract blend, consisting of white mulberry extract, peony extract and orchid extract.
Biotin contributes to normal energy metabolism and the maintenance of normal hair, but it is important to distinguish the role of this individual micronutrient from the overall purpose of the product.
Metabolic-GL can therefore be considered among the alternatives that provide biotin through a formulation primarily intended to meet a different nutritional need.
- Biotin per tablet: 50 µg.
- Other ingredients: vitamin D and the METAGL+ plant blend.
- Format: 30 tablets.
- Features: vegan, gluten-free and lactose-free.
5. Vitamin-Plus 12 Sachets – TN Pharma
Vitamin-Plus by TN Pharma is a multivitamin and multimineral supplement in sachets, formulated to provide several micronutrients that contribute to the normal functioning of the body.
Each sachet contains 50 µg of biotin, equivalent to 100% of the Nutrient Reference Value.
The formulation contains a total of 13 vitamins and 9 minerals, including vitamin C, vitamin D, vitamin E, B vitamins, zinc, iron, magnesium, selenium and iodine.
The presence of biotin means this product can also be included among supplements that provide vitamin B7, although its formulation is not specifically intended to support hair health.
Vitamin-Plus is therefore an option to consider when looking for a comprehensive multivitamin product rather than a supplement focused exclusively on biotin.
- Biotin per sachet: 50 µg.
- Other ingredients: 13 vitamins and 9 minerals.
- Format: 12 sachets.
- Recommended use: dissolve one sachet in 150–200 ml of water and take once a day.
- Features: suitable for vegetarians, gluten-free and lactose-free.
6. Vitamin Strong Pure Professional 160 Tablets – Tsunami Nutrition
Vitamin Strong Pure Professional is a multivitamin and multimineral supplement that combines vitamins, minerals and various functional ingredients.
The daily serving, consisting of two yellow tablets and two purple tablets, provides 25 µg of biotin, equivalent to 50% of the Nutrient Reference Value.
The micronutrients include vitamin C, vitamin E, vitamin A, vitamin D, vitamin K2 and several B vitamins, as well as minerals such as zinc, iron, magnesium, copper and selenium.
The formulation also contains other ingredients, including Ribodiet® yeast nucleotides, Veri-te™ trans-resveratrol, L-carnitine, N-acetyl cysteine, coenzyme Q10 and lutein.
The presence of biotin makes Vitamin Strong another option for those who want to supplement this micronutrient through a more comprehensive multivitamin product.
However, it is important to remember that this product is not specifically formulated to prevent hair loss or promote hair growth.
- Biotin per daily serving: 25 µg.
- Other ingredients: vitamins, minerals, Ribodiet®, Veri-te™, L-carnitine, N-acetyl cysteine and coenzyme Q10.
- Format: 160 tablets.
- Recommended use: 2 yellow tablets and 2 purple tablets per day.
Best supplement for hair growth
When the goal is to support hair health, it is important to distinguish a biotin supplement from a formulation specifically designed for hair.
Vitamin B7 contributes to the maintenance of normal hair, but it is not the only micronutrient involved in this process. Zinc and selenium, for example, also contribute to the maintenance of normal hair, while copper contributes to normal pigmentation.
For this reason, a formula combining several nutrients may be of interest to those looking for a broader intake than biotin alone can provide.
Among the products reviewed, +Capelli by TN Pharma is the one most specifically geared towards hair health. Its composition combines biotin, zinc, selenium, copper, L-methionine, vitamin E, bamboo extract and Annurtrofil®.
It is important to clarify that no supplement can guarantee hair regrowth or resolve every type of hair loss. The effectiveness of supplementation also depends on an individual's nutritional status and any underlying causes of the problem.
How to choose the best biotin supplement for hair
Not all biotin supplements are the same. Your choice should take into account the amount of vitamin B7 in the formulation, the other ingredients and how convenient the supplement is to take.
Let's look at the factors to consider before buying a product.
Dosage and daily intake
Dosage is one of the first factors to consider when choosing a biotin supplement.
According to the reference values established by EFSA, the adequate intake of biotin for adults is 40 µg per day. This value represents the total intake considered adequate, not a specific amount that should be obtained from supplements.
It is important to remember that requirements are normally met through a varied and balanced diet, and that the necessary amount may already be present in everyday foods.
Supplements available on the market can contain very different concentrations, ranging from multivitamin formulations with amounts close to reference values to high-dose products such as Biotin by TN Naturals, which provides 10,000 µg per tablet.
However, a higher dosage does not necessarily mean better results for hair. Before choosing a high-concentration product, it is advisable to assess your needs with a healthcare professional.
Formulation and synergistic nutrients
Another factor to consider is the supplement's overall composition.
Some products contain biotin alone, while others combine it with vitamins, minerals and complementary ingredients.
Nutrients worth considering include:
- Zinc: contributes to the maintenance of normal hair.
- Selenium: contributes to the maintenance of normal hair.
- Copper: contributes to normal hair and skin pigmentation.
- Vitamin C: contributes to normal collagen formation for the normal function of the skin.
- Vitamin E: contributes to the protection of cells from oxidative stress.
There are also formulations containing collagen, keratin and plant extracts, which are intended to provide a broader range of ingredients.
The choice between a simple formula and a more comprehensive one depends on your nutritional needs. However, a product should not automatically be considered more effective simply because it contains a greater number of ingredients.
Type and format of supplement
Biotin is available in several formats, including:
- Tablets: they are easy to dose and make it possible to know precisely how much biotin each unit contains;
- Capsules: these are an alternative to tablets and can contain formulas with several ingredients;
- Sachets: these may contain powders to be dissolved in water and are convenient for those who prefer not to take tablets.
There is no universally best format: the choice depends on personal preferences, composition and the instructions provided by the manufacturer.
Always follow the daily serving indicated on the label and avoid combining several supplements containing biotin without first assessing your total intake.
Supplement evaluation methodology
To select the six Tsunami Nutrition products included in this guide, we primarily considered whether biotin was actually present in the formulation and the amount provided per daily serving.
The selection includes both supplements in which biotin is the main ingredient and multivitamin products or more comprehensive formulas that contain vitamin B7 alongside other nutrients.
Our evaluation considered:
- Presence of biotin: we included only products that list vitamin B7 in their composition;
- Amount per daily serving: we compared the quantities stated on the label, distinguishing between amounts per tablet, sachet and daily serving;
- Composition: we considered the presence of other ingredients, such as vitamins, minerals, plant extracts, collagen and keratin;
- Purpose of the formulation: we distinguished products specifically intended to support hair health from those designed for multivitamin supplementation or other nutritional needs;
- Format: we considered the different available ways of taking the supplements.
Frequently asked questions about biotin for hair
What is the difference between vitamin B7 and vitamin B8?
Vitamin B7 and vitamin B8 are names used to refer to biotin, which is also known as vitamin H. The terminology may vary depending on the context and country, but it refers to the same molecule.
Biotin belongs to the group of water-soluble vitamins and is involved in the metabolism of carbohydrates, fats and proteins, contributing to normal energy metabolism. It also contributes to the maintenance of normal hair and skin.
How much biotin should you take daily for your hair?
The amount of biotin to take each day depends on dietary intake and individual needs. According to EFSA, the adequate intake for adults is 40 µg per day.
There is no specific biotin dose, however, that has been established to promote hair growth or prevent hair loss. Supplements can provide different amounts of vitamin B7, but a higher dosage does not automatically guarantee greater benefits.
Are biotin supplements effective in preventing hair loss?
Biotin supplements are not necessarily effective in preventing hair loss in everyone. Vitamin B7 contributes to the maintenance of normal hair, but this does not mean that supplementation can resolve every problem involving thinning or hair loss.
Biotin deficiency may be associated with hair loss, but this is a rare condition. Furthermore, scientific evidence supporting the use of biotin supplements to improve hair growth in people who are not deficient is still limited.
Hair loss can have many different causes, including genetic predisposition, hormonal changes, stress, nutritional deficiencies and scalp conditions. For this reason, if the problem persists, it is important to identify the cause with the help of a dermatologist.
Does taking biotin for hair have any contraindications or side effects?
Biotin is generally considered well tolerated, but taking supplements still requires certain precautions. Anyone taking biotin supplements should inform their doctor and laboratory before having blood tests, so that any necessary precautions or the temporary discontinuation of the product can be assessed.
In cases of pregnancy, breastfeeding, medication use or specific health conditions, it is advisable to consult a doctor before starting supplementation.
