Pure Encapsulations Biotin Complex Hair & Skin
- Why we love it: “As a healthcare professional, I trust third-party tested brands like Pure Encapsulations,” says Carla Hernandez, a registered dietitian who specializes in women’s health in Los Angeles, California. She specifically recommends this Biotin Complex hair and skin supplement because it contains magnesium biotinate, which she considers a “better” option because it’s a safe and fast-absorbing form. Additionally, it contains arginine and silica for enhanced hair and nail support.

Health Holistic Beauty Collagen Design
- Why we love it: If healthy skin, hair, and nails are a top concern, it can be helpful to take a supplement that contains other supportive ingredients in addition to biotin, such as a collagen supplement. “I also love Designs for Health’s Whole Beauty Collagen, which combines biotin with collagen peptides to support skin, hair, and nails,” says Hernandez. This tasteless, dissolvable powder supplement is also a good option for people who don’t like swallowing pills. It’s also worth noting that it contains magnesium biotinate, a form that is highly absorbable in the body.
