Biotin is a vital micronutrient crucial for the body, and the body, unable to produce it by itself, must acquire it through food absorption. Biotin is categorized within the B-vitamin group and is alternatively referred to as vitamin H, vitamin B7, or vitamin B8 in France.  

Biotin is considered a "beauty vitamin": Research conducted by the European Food Safety Authority (EFSA) has revealed that biotin plays a significant role in maintaining the normal health of skin and hair. [1]

Additionally, the practice of using high doses of biotin for the treatment of brittle or splitting nails, which is not based on clinical studies, is also common. [2] 

The following information has been scientifically studied and confirmed by the European Food Safety Authority (EFSA). [1]

"Food supplements are effective when the right nutrients are consumed by appropriate individuals at the right time and in the correct amounts." (verbraucherzentrale.de) [4] 

Vitality Nutritionals Biotin 5 mg (5,000 µg) capsules are particularly suitable for  

• Individuals who want to optimize their nutrient supply for skin and hair 
• Individuals with an increased need for biotin, e.g. due to taking medication  
• Regular smokers (nicotine consumption), as smoking accelerates the biotin metabolism and can therefore lead to a slight biotin deficiency 
• Individuals with high alcohol consumption, as regular alcohol consumption can lead to a biotin deficiency and deficiency symptoms such as thinning hair, dry or blemished skin [2] 
• etc. 

The amount required in each individual case should be clarified with a specialist to ensure optimum individual dosage. The recommended daily intake of one capsule with a glass of water after a meal must not be exceeded. 

Vitality Nutritionals Biotin 5 mg (5,000 µg) capsules should be kept out of the reach of children. This food supplement is not suitable as a substitute for a balanced, varied diet and/or a healthy lifestyle.  

People with health problems should consult their doctor before using the product. 

If you have health problems and/or are taking medication, you should always seek medical advice before taking food supplements. To date, there are no known adverse health effects associated with biotin, even with an increased intake of up to 20,000 µg per day. [2] Biotin is classified as a water-soluble vitamin, meaning any excess is typically excreted through the kidneys.  

However, taking biotin can potentially interfere with blood test results. Specifically, tests for thyroid hormones, sex hormones, and cardiovascular markers like troponin (used for detecting heart attacks) may yield inaccurate results, either as false positives or false negatives. If you are taking or have recently taken a dietary supplement containing biotin, it is important to notify medical staff when undergoing blood tests. [2]
