Synovial & Skin Support
What Is High Molecular Weight Hyaluronic Acid?
Hyaluronic acid (HA) is a naturally occurring substance found throughout the body — particularly in joints, connective tissues, skin, and eyes — where it helps tissues retain water, maintain elasticity, and support normal function. High Molecular Weight Hyaluronic Acid (HMW-HA), roughly one million Daltons or greater, is included in IRx-ZEUS® for humans to support mobility, joint wellness, skin health, and overall quality of life.
What Makes HMW-HA Unique
HA exists in a range of molecular sizes, and molecular weight may influence biological behavior. HMW-HA is naturally abundant in healthy tissues and associated with joint lubrication, tissue hydration, connective-tissue integrity, skin moisture retention, and support of normal inflammatory balance (Cowman et al., 2015; Litwiniuk et al., 2016).
Joint Health & Mobility
HA is a major component of synovial fluid, and endogenous levels may decline with aging and joint degeneration. Several human clinical studies have reported improvements following oral HA supplementation in measures related to:
- Joint comfort
- Mobility
- Physical function
- Activities of daily living
These outcomes were reported by Tashiro et al. (2012) and Kalman et al. (2008), supporting HA’s role in helping maintain normal lubrication and healthy connective-tissue function.
Skin Health & Appearance
Skin contains roughly half of the body’s hyaluronic acid reserves, where HA maintains hydration within the extracellular matrix. Human studies have reported improvements in skin hydration and appearance following oral HA supplementation (Oe et al., 2017; Kawada et al., 2014).
HA plays a recognized role in normal tissue-repair processes and contributes to the integrity of epithelial and mucosal surfaces. Evidence in respiratory and wound-healing contexts remains preliminary. The strongest healthy-aging rationale remains support of mobility, skin wellness, and physical function; there is no evidence that oral HA extends lifespan.
Safety Profile
Published research generally reports oral hyaluronic acid supplementation to be well tolerated, with uncommon and typically mild side effects. Individuals with medical conditions or taking medications should consult a healthcare professional.
The ActivPower Perspective
ActivPower includes High Molecular Weight Hyaluronic Acid in IRx-ZEUS® for humans as part of comprehensive formulations intended to support mobility, healthy movement, skin wellness, and overall quality of life.
