Dr. Mark Rosenberg on HydraFlex

Hyaluronic Acid is like a little sponge for moisture - it can hold up to 1000x its own weight in water! So it does amazing double duty: first, in plumping up the skin and helping with moisture retention, and second, supporting joint health and comfort. It's wonderful for anyone who sees or feels the effects of age!

The Top Reasons To Take HydraFlex

According To The Clinical Studies

Top Reason icon

Healthy, Comfortable Joints

Hyaluronic acid is a building block for joints - it actually lines the joint walls, and keeps them lubricated and moving easily. Studies show that 80-200mg daily can lead to significant relief for in the knees, especially for people 40-70 years old.

Moist, Plump Skin

Roughly half of the Hyaluronic Acid in your body is found in your skin, trapping moisture for a plump, firm glow. But your natural levels decline with age, so it's essential to supplement! 120-240mg per day have been shown to dramatically increase moisture, and reduce dryness.

Frequently Asked Questions

With Dr. Mark Rosenberg

How does hyaluronic acid work?

It's sure strange they called it an acid - more appropriate would be something like "water sponge." This ingredient sucks up moisture in the air and in your body, and delivers it where it's so needed - your skin, and your joints.

I'm already using a hyaluronic acid moisturizer - why should I take a supplement too?

Your body naturally produces plenty of hyaluronic acid when you're young, but levels naturally decline with age. Most moisturizers can't penetrate the skin deep enough to support moisture in lower layers of the dermis... and they'll do nothing for your joint health. For plump skin from within, and smooth lubricated joints, there's no alternative to a supplement.

Is there anyone who shouldn't take HydraFlex?

One study of 60 people, who took 200mg daily, showed no side effects or complications. But as with all supplements, consult with your healthcare provider before starting HydraFlex.
