Santarome Biotine+ is a dietary supplement in capsule form that combines biotin (vitamin B8), keratin hydrolysate, zinc, selenium, and vitamin E. Biotin helps maintain normal hair and normal skin; zinc and selenium help maintain normal nails.
Santarome Biotin+ 10,000 µg is a dietary supplement in capsule form that combines biotin (vitamin B8) with keratin hydrolysate, zinc, selenium, and vitamin E. Two capsules provide 10,000 µg of biotin. This water-soluble vitamin, which the body does not store, is the key active ingredient in many dietary supplements for hair, where it is often combined with minerals.
Biotin helps maintain normal hair and normal skin. It is also found in food, particularly in egg yolks, organ meats, oilseeds, and legumes.
Zinc and selenium help maintain normal hair and normal nails. Vitamin E, for its part, helps protect cells against oxidative stress. These three nutrients are formulated at half the reference values for two capsules, leaving room for those obtained from the diet.
The formula is intended for adults who wish to support the health of their hair and nails from the inside, for example during seasonal changes, after a period of fatigue, or following a diet lacking in variety. It complements a balanced diet and gentle care routines, without replacing them.
A capsule works through the diet; the nail, which is already formed, also requires surface care. For this, we recommend Mavala Nailactan Nourishing Cream, to be massaged every evening onto damaged, devitalized, and brittle nails. Rich in amino acids, lipids, and vitamins, it is massaged directly onto the nail plate: the two treatments complement each other—one through nutrition, the other topically—without adding biotin or zinc to those already in the formula.
Directions for Use
Take 1 to 2 capsules daily with a large glass of water, preferably in the morning.

Packaging
Pill bottle containing 60 capsules, enough for one month at a dose of 2 capsules per day, or two months at a dose of 1 capsule per day.
Before taking the first capsule, the question we ask isn’t about the dosage but about your next blood test. The catch is that there’s no one-size-fits-all waiting period for stopping the supplement: it depends on the test, the lab’s methodology, and the amount taken. Stopping the day before at random therefore offers no protection. The best practice is to mention it every time you have blood drawn, even for a routine checkup. It’s also worth keeping this in mind if you visit the emergency room.
As we often remind customers at the counter: hair and nails reflect your overall health. Iron deficiency, a protein-deficient diet, a restrictive diet, or hormonal changes have a much greater impact than a vitamin. If nothing has changed after completing the course, the cause lies elsewhere: a consultation with your doctor will identify it, not a second box.
Does a 10,000 µg dose of biotin in Santarome Biotine+ pose a risk to my health?
There is no established maximum daily intake for biotin in France, as it is considered a low-risk vitamin in dietary supplements. With Santarome Biotine+, the main concern lies elsewhere: it relates to laboratory tests, which require specific precautions.
What is the difference between Santarome Biotine+ and a biotin supplement containing 1,000 µg?
The reference nutritional value for biotin is 50 µg per day. A 1,000 µg biotin supplement provides twenty times that amount; Santarome Biotine+ provides one hundred times that amount with one capsule, and two hundred times that amount with two. A higher dosage does not guarantee better results, since excess biotin is not stored by the body.
What is the purpose of the keratin in Santarome Biotine+?
Keratin is the protein that makes up most of the hair and nails. Santarome Biotine+ provides it in the form of a hydrolysate—that is, broken down into smaller fragments—to complement the biotin and minerals in the formula.
Can I take Santarome Biotine+ all year round?
Santarome Biotine+ should be taken in two- to three-month courses, followed by a break, rather than continuously. This alternating schedule allows you to assess the effectiveness of each course and avoids a very high and prolonged intake of a vitamin for which daily requirements are low.
