Hyaluronic Acid
Hyaluronic Acid (Hyaluronan)
A naturally occurring molecule that supports skin hydration, joint lubrication, and tissue health.
Hyaluronic Acid is a glycosaminoglycan naturally found in skin, joints, and eyes. It can hold 1,000 times its weight in water, making it essential for tissue hydration. Oral supplementation has been shown to improve skin hydration and wrinkles, as well as support joint comfort. Different molecular weights have different effects - lower weights absorb better orally.
Mechanisms of Action
Super Hydration
Holds up to 1,000x its weight in water
Joint Lubrication
Main component of synovial fluid
Skin Matrix Support
Supports the extracellular matrix
Recommended Dose
120-240mg daily
Loading: Not required
Optimal Timing
- With food
- Once daily
Take with food
Best Form
Low molecular weight hyaluronic acid capsules
Alternatives: Higher molecular weight forms, Topical (for surface skin only)
Look for low molecular weight (below 1000 kDa) for better absorption. Topical HA doesn't penetrate deeply.
Duration
Minimum: 8 weeks
Optimal: 16 weeks
Cycling: Not required
Note: Consistency is more important than timing. Lower molecular weight HA absorbs better.

Zhang J et al. âĒ Lasers in medical science (2023)
âThe Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature.â
Key Findings:
- In addition, fractional CO2 laser combined with HA dressing therapy had a lower incidence of hyperpigmentation than fractional CO2 laser alone (RR=0.37, 95% CI [0.23, 0.61], P<0.0001).
- The level of evidence for outcomes was classified to be low to moderate.
- According to our findings, fractional CO2 laser combined with HA dressing is efficacious and safe option for facial atrophic acne scars.
- Nevertheless, more high-quality trials are required for further verification in the future.ÂĐ 2023.
Bannuru RR et al. âĒ Annals of internal medicine (2015)
âThis method allowed comparison of common treatments of knee OA according to their relative efficacy.â
Key Findings:
- This method allowed comparison of common treatments of knee OA according to their relative efficacy.
- Intra-articular treatments were superior to nonsteroidal anti-inflammatory drugs, possibly because of the integrated IA placebo effect.
- Small but robust differences were observed between active treatments.
- All treatments except acetaminophen showed clinically significant improvement from baseline pain.
Gupta N et al. âĒ Journal of orthopaedic surgery and research (2025)
âThese findings emphasize the sustained efficacy of PRP, particularly when combined with HA, in providing superior long-term pain relief and functional improvement in knee OA compared to other intra-articular injectables, highlighting its potential as a preferred treatment modality.â
Key Findings:
- These findings emphasize the sustained efficacy of PRP, particularly when combined with HA, in providing superior long-term pain relief and functional improvement in knee OA compared to other intra-articular injectables, highlighting its potential as a preferred treatment modality.
- Published in Journal of orthopaedic surgery and research (2025)
- Further research warranted to confirm findings
Jawanda H et al. âĒ Arthroscopy : the journal of arthroscopic & related surgery : official publication of the Arthroscopy Association of North America and the International Arthroscopy Association (2024)
âAt a minimum 6-month follow-up, PRP demonstrated significantly improved pain and function for patients with knee osteoarthritis compared with placebo.â
Key Findings:
- The most studied intra-articular injection was HA (40.9%), followed by placebo (26.2%), PRP (21.5%), CS (8.8%), and then BMAC (2.5%).
- HA and PRP both led to a significant improvement in pain compared with placebo.
- HA, PRP, and BMAC all led to a significant improvement in function scores when compared with placebo.
Luo Y et al. âĒ American journal of obstetrics and gynecology (2024)
âHyaluronic acid can safely and effectively reduce the incidence of intrauterine adhesions and may improve fertility outcomes.â
Key Findings:
- The analysis revealed that hyaluronic acid reduced the incidence of intrauterine adhesion (risk ratio, 0.53; 95% confidence interval, 0.42-0.67; I2=48%) and improve pregnancy rates (risk ratio, 1.24; 95% confidence interval, 1.02-1.50; I2=0%).
- The protective effect was statistically significant after a follow-up of 6 to 12 weeks.
- Hyaluronic acid can safely and effectively reduce the incidence of intrauterine adhesions and may improve fertility outcomes.
