How does biotin help your nails?
You may have heard of biotin, which is a B complex vitamin that the body needs for various functions such as converting food into energy and helping your body produce fatty acids. Biotin is widely recommended as a nutrient that can help with the strength and quality of nails.1
Nails are made up of layers of a protein called keratin. When we ingest biotin, it reacts with cell enzymes and plays a vital part in producing amino acids, which are the building blocks of all proteins, including keratin. Biotin deficiency, although rare, can cause brittle and flaking nails, as well as hair loss, acne and eczema.2
One landmark study carried out in Germany showed that 91% of people reported firmer and harder nails after taking 2.5mg of biotin each day for several months.3

Rich sources of biotin include eggs, almonds, spinach and sweet potato.
Your nails grow at a rate of around 3mm per month5
