What is Biotin?
Biotin, also known as Vitamin B7 or Vitamin H, is part of the B-vitamin group and plays a vital role in helping the body convert food into energy. It’s essential for the metabolism of carbohydrates, proteins, and fats. Biotin is found naturally in foods like eggs, fish, meat, seeds, nuts, and certain vegetables.
This vitamin is crucial for nervous system health and supports the creation of keratin, the key protein that forms hair, skin, and nails. It also contributes to stable blood sugar levels and supports a healthy metabolism. Due to these benefits, Biotin is commonly associated with improving hair growth and enhancing the condition of skin and nails.
Individuals who are deficient in Biotin may struggle to absorb enough through diet alone, making injections a more effective option.

Why get Biotin injections?
Since Biotin is water-soluble, the body doesn’t store it, any excess is flushed out naturally. That’s why it’s important to maintain a steady supply. While oral supplements are widely available, intramuscular injections are often more efficient, delivering Biotin directly into the bloodstream for faster absorption and better results.
Proper Biotin supplementation has been linked to stronger, healthier hair, improved hair thickness, and reduced shedding. Many users also report stronger nails, research shows that Biotin can increase nail thickness by up to 25% and reduce splitting or breakage.
Interestingly, some individuals also notice a boost in libido while using Biotin, though this is likely a by-product of overall improved wellbeing, as there is currently no scientific evidence proving a direct connection.
