Noticed an improvement in my nails, they are so much stronger and healthier. Also the tablets are a small size for easy swallowing. Package small too. Great quality and better than other brands . No taste
Very good product in this concentration. Concentration of 5 g per tablet is optimal for woman body, is optimal for me for betterment of the hair and nails health. Initially, I wanted to buy biotin of 10 g per tablet, but meantime I read a lot about these supplements ( I have some chemical and pharmaceutical knowledges) and I realized that Biotin of concentration of 10 g per tablet is too much for me. Everybody must study and analyze all condition regarding own human body before to order a certain product.
