Frequently Asked Questions

Liquid Collagen + Biotin

What is collagen?

Collagen is the largest and most abundant protein building block in our body -- which contributes directly to our skin’s firmness, suppleness, and elasticity.

What is Biotin?

Biotin is a B-complex vitamin that helps the body convert food into energy. Biotin occurs naturally in many foods, but using a supplement provides a higher dose of biotin to further support healthy hair, skin, and nails.

What types of collagen are used in Zena™ Liquid Collagen + Biotin?

Zena™ Liquid Collagen + Biotin contains collagen types I and III. 

What is the difference between Type I and Type III?

Type I collagen may help contribute to healthier hair, skin smoothness, and elasticity.
Type III collagen may help stimulate the production of the amino acid glycine, the building block for building muscle.

Why do I need Zena™ Liquid Collagen + Biotin?
