Thicker hair in 3 weeks.*
MyBiotin® ProClinical features MB40X™ — 40x more soluble than standard biotin, so your body actually absorbs what it needs for thicker, fuller hair in 3 weeks.*
Why 10,000+ women
choose MyBiotin® every month**
Powerful doses. Key clinically studied ingredients.
Most biotin supplements fall short because standard biotin isn't designed for optimal absorption. MyBiotin® ProClinical is different. MB40X™ pairs Magnesium Biotinate with Arginine Silicate — creating a form of biotin that's 40x more soluble than standard biotin.* That means your body can actually utilize the nourishment needed to support hair density, strength, and visible fullness.*
A clinically studied biotin complex for optimal absorption and visible hair-thickening results.*
A powerful antioxidant that helps protect skin from oxidative stress, promotes hydration, and supports a smoother, more youthful complexion.*
Real change doesn't happen overnight. But with consistent daily use, many women experience visible improvements in fullness, strength, and overall hair appearance over time.*
Increased hair thickness (thicker/fuller)*
Continued improvements in thickness*
Improved ratio of vellus hair & percentage of terminal hair*
Noticeable increase in hair thickness up to 20%*
*Results may vary. Based on consistent daily use.
Before & Afters
After weeks of consistent use, real women experienced thicker-looking hair with MyBiotin® ProClinical.*
For over 30 years, Purity Products® has built supplements around named, clinically studied ingredients — not generic formulations. MyBiotin® ProClinical is no exception.
MB40X™ (Lustriva®) and AstaPure® are both branded, independently studied ingredient complexes — not the commodity biotin you'll find in most supplements. Every batch is manufactured in a GMP-certified facility. You know exactly what's in it, and you know it's been held to a standard.
