Collagen is an essential part of maintaining strong and youthful skin, hair, and nails. So it’s no wonder that everyone is running to get discounted Vital Proteins collagen powders at the Amazon Big Spring Sale.

To answer all your collagen powder questions, we spoke to board-certified dermatologist Dr. Jenna Queller.

What is collagen and what does it do?

According to Dr. Queller, “collagen is the most abundant protein in the body and serves as a critical building block for our skin, hair, nails, joints, and connective tissue.”

It’s responsible for elasticity and firmness (aka what keeps skin, hair, and nails lookings youthful). “As we age, collagen production naturally declines, leading to fine lines, thinning hair, and more brittle nails. So maintaining collagen levels is key not just for appearance, but for overall structural health,” Dr. Queller explains.

For that reason, many people add collagen peptide supplements, like those from Vital Proteins, do their daily wellness routine.

Do collagen powders work?

“The truth is, collagen supplements aren’t a miracle—but they’re not a myth either,” says Dr. Queller. “There is growing scientific evidence showing that specific, clinically studied collagen peptides can modestly improve skin elasticity, hydration, and the appearance of fine lines over time.”

However, she emphasizes that not all collagen powders are created equal.

“If you’re going to take collagen, it’s important to look for clinically tested ingredients at the correct doses,” advises Dr. Queller. Luckily, Vital Proteins is made with clinically researched ingredients, making it an effective and simple way to boost collagen production in your body.
