Imagine waking up, looking in the mirror, and your skin glowing. Your hair feels strong and vibrant, and your nails? No more splitting. You know you're doing something good for your body, and maybe with biotin .
You may have heard of it before: Biotin, also known as vitamin B7 or vitamin H , isn't called the "beauty vitamin" for nothing. But what's really behind it—and why do so many women swear by its effectiveness?
What exactly is biotin – and why is it so important for you?
Biotin is a water-soluble B-complex vitamin that your body needs every day. It helps you convert carbohydrates, fats, and proteins from food into energy—energy you need for all the roles you fulfill every day: as a powerful woman, mother, dreamer, and doer.
But biotin is more than just an energy booster. It plays a crucial role in your skin, hair, and nails —the external mirrors of your internal health.
The effect of biotin – noticeable in your everyday life
For your hair: More than just a styling product
Who hasn't experienced it – hair that looks dull, increased hair loss after stressful periods or hormonal changes? Biotin helps your body produce keratin – the structural protein that makes your hair strong, elastic, and shiny.
- Promotes healthy hair growth
- Can reduce hair loss in cases of deficiency
- Gives your hair back its natural vitality
For your nails: goodbye to breakage
Do you paint your nails regularly, but they still split? This could be a sign of a nutrient deficiency. Biotin helps strengthen your nail structure and make it more resilient .
- Strengthens nails from the inside
- Reduces brittleness
- Promotes natural growth
For your skin: Radiant, not stressed
Dry, flaky, or dull skin often has underlying causes. Biotin supports cell renewal and ensures balanced skin metabolism .
- Helps with dry or irritated skin
- Supports the regeneration of skin cells
- Promotes a naturally fresh skin appearance
If your body is missing something – symptoms of a deficiency
Biotin deficiency is rare, but can be caused by certain life phases or conditions:
- Pregnancy or breastfeeding
- Certain medications (e.g. antibiotics, antiepileptics)
- Digestive diseases such as Crohn's disease
- One-sided diet or diets
- Excessive consumption of raw egg whites
Typical symptoms that you should take seriously:
- Increased hair loss
- Brittle, soft nails
- Dry, flaky skin or eczema
- Fatigue, lack of motivation, depressive moods
- Muscle pain
Biotin in food – these sources are good for you
Your body can't produce biotin on its own. You must therefore obtain it through food or supplements. Foods that are particularly rich in biotin include:
- Boiled eggs
- Nuts & Almonds
- oatmeal
- Salmon & beef liver
- avocado
- Legumes
- Bananas
Tip: Gentle cooking preserves the biotin content – so steam rather than fry.
Biotin supplementation – when does it make sense?
Many women experience it at some point: their skin changes, their hair becomes finer, their nails more sensitive. Especially during times of hormonal changes, high stress, or simply with increasing age, biotin supplementation can provide noticeable support .
Common dosages range from 2,500 to 10,000 µg daily – significantly higher than the recommended daily intake of 30–60 µg.
What does research say?
- Biotin has been proven to be effective in cases of clinical deficiency
- Even without a deficiency, it can have a supportive effect , for example after stress or for beauty goals
- Biotin complements other nutrients such as collagen or zinc
Important: High-dose biotin may affect laboratory results. Please consult your doctor before undergoing blood tests.
Your questions – answered honestly
How quickly will I see results with biotin?
The first changes in hair and nails usually appear after 3–6 weeks . For the skin, it usually takes about 8 weeks .
Can you take too much biotin?
The body usually excretes excess biotin through urine. Nevertheless, please only take high doses specifically—not just on suspicion.
Does biotin cause skin blemishes?
In rare cases, yes—usually due to an imbalance in B vitamins. A complete B complex can help.
