Hyaluronic acid

Hyaluronic Acid (HA) is a naturally occurring substance in your body, acting like a super-sponge for moisture. Roughly 50% of your body's HA is found in your skin, keeping it plump and hydrated. As we age, our natural production slows down, leading to dryness and wrinkles. While famous in skincare, taking it orally helps support hydration from the inside out, benefiting your joints, eyes, and skin elasticity. Think of it as internal moisturizer.

Health Benefits & Sources

Why You Need It

Skin Hydration: Increases water retention in the skin, reducing the appearance of fine lines.
Joint Lubrication: Acts as a shock absorber, cushioning bones and cartilage.
Eye Health: Helps maintain fluid balance in the eyes.

Deep Dive

Hyaluronic Acid works via osmotic regulation—it attracts and holds onto water molecules (up to 1,000 times its weight!). When you ingest HA, it is partially broken down into smaller fragments that signal your body to ramp up its own production and hydrate tissues. Studies show that oral HA can significantly improve skin moisture and reduce joint pain in osteoarthritis patients within weeks.

Natural Food Sources

While you can't 'eat' hyaluronic acid directly from produce, you can eat foods that stimulate its production. Bone broth is the jackpot, but plant-based antioxidants help prevent its breakdown.

Food	Amount	% DV
Bone Broth	1 cup	High (Natural HA)
Soy Products	1/2 cup	Moderate (Estrogen boost)
Leafy Greens	1 cup	Low (Antioxidants)
Root Vegetables	1 cup	Low (Magnesium source)

Supplementation

Most supplements use Sodium Hyaluronate, a salt form that is more stable and easily absorbed.

Dosage: 100mg to 200mg daily is the standard effective dose.
Who should take it: Those with dry skin, joint stiffness, or athletes looking for joint support.

Soy (Tofu, Edamame)

Contains phytoestrogens that boost HA

Sweet Potatoes

Provides magnesium for HA synthesis

Citrus Fruits

Vitamin C prevents HA breakdown

Leafy Greens

Frequently Asked Questions

They work differently. Topical HA sits on the surface to instantly plump skin. Oral HA works systemically to improve hydration from within and supports joint health.

Most studies show noticeable improvements in skin moisture and joint comfort after 4 to 8 weeks of consistent daily use.

Yes, indirectly. By deeply hydrating the skin, it reduces the visibility of fine lines caused by dehydration, though it won't erase deep structural wrinkles.

Most HA supplements are derived from rooster combs (animal source) or fermented bacteria (vegan). Both are chemically identical and safe. Check the label if you are vegan.

Safety & Side Effects

Hyaluronic Acid is generally recognized as safe (GRAS) by the FDA.

Side Effects: Extremely rare. Mild bloating or nausea can occur if taken in massive doses.
Interactions: None known.
Who should avoid: Pregnant or breastfeeding women should stick to dietary sources and consult a doctor, as safety data is limited.
