Lab Studies Document the Importance of the Hyaluronic Acid Found in the H.A. Joint Formula™

Maintaining healthy joint and connective tissue health as we age is the result of a number of complex interactions within our bodies and in our joints. Some factors that influence joint health are protection from oxidative damage, normal and balanced functioning of various enzymatic processes, support and enhancement of immune function, and maintenance of healthy and strong connective tissue. Purity’s H.A. Joint Formula™ is a potent combination of antioxidants and extracts with known joint-supportive properties and hyaluronic acid, which has immune-enhancing and connective-tissue rejuvenating properties and contributes to the structural matrix of joint cartilage and skin.*


Purity’s H.A. Joint Formula™ has recently been evaluated in a number of laboratory assays which highlight important mechanisms detailing how the formulation may support and enhance healthy joint and connective tissue function. These laboratory studies include the following:

  • In vitro evaluation of H.A. Joint Formula for anti-inflammatory and immune modulating effects in a human cell-based system. These tests include measurements of effects on the inflammatory response, activation of immune cells, and assessment of antioxidant activity in a cell-based assay.*
  • In vitro elastin release assay. This measures the ability of the product to stimulate elastin release. Elastin is a protein found in our skin, as well as in the walls of our arteries, lungs, and intestines. Elastin is secreted by fibroblasts of the connective tissue and contributes to skin elasticity and tonicity.*
  • In vitro collagenase enzyme inhibition assay. Collagenase is an enzyme that degrades collagen, the main structural component of skin, cartilage and other connective tissue. Increased collagenase activity may be detrimental to skin health and joint function. *


  • H.A. Joint Formula was found to significantly inhibit the activity of the inflammatory enzymes COX-2 and lipoxygenase in vitro, signifying potential of the product to maintain tissue comfort and cooling effects in joints.*

  • H.A. Joint Formula exhibited antioxidant effects in human red blood cells and polymorphonuclear (PMN) cells in vitro, a type of white blood cell. The product prevented the formation of reactive oxygen species, or free radicals, indicating that H.A. Joint Formula™ may contain antioxidants able to enter and protect cells from oxidative damage. This antioxidant effect supports normal joint function by maintaining and protecting joint health from damage caused by free radicals.*

  • H.A. Joint Formula led to statistically significant increases in elastin levels in human fibroblast cells in vitro. This highlights the potential ability of the product to support the healthy structure and function of connective tissue and skin. Adequate elastin production is essential to preventing wrinkles and premature skin aging.*

  • H.A. Joint Formula inhibited activity of the enzyme collagenase in vitro at all concentration levels tested. H.A. Joint Formula™ may support the normal, healthy repair and function of connective tissue, including skin health and cartilage structure.*

H.A. Benefits

  • H.A. Joint Formula™ may inhibit the production of a number of pro-inflammatory substances, potentially contributing to sensations of increased joint comfort and ease.*
  • H.A. Joint Formula™ has direct antioxidant effects in human red blood cells and PMN cells (a type of white blood cell), indicating protection from the potentially harmful effects of oxidative damage.*
  • H.A. Joint Formula™ supports the maintenance of healthy, strong connective tissue. H.A. Joint Formula™ inhibits the enzyme collagenase, which is involved in the breakdown and degradation of connective tissue. H.A. Joint Formula™ also enhances the production of elastin in connective tissue, an important protein involved in connective tissue remodeling.*
