Urolithin Research Opens Door to Osteoarthritis Relief

Urolithin A supplementation may improve mitochondrial health and reduce joint cartilage damage, a new study shows.

Scientists from Amazentis and Scripps Research have shown that urolithin A supplementation not only reduces pain in osteoarthritis sufferers, but can also improve mobility as it has a beneficial effect on the structural damage that osteoarthritis causes.

Longevity.Technology: Osteoarthritis is one of the most common types of arthritis and occurs when the protective cartilage that cushions and protects the ends of bones wears away. The risk of osteoarthritis increases with age, occurs more frequently in women than in men – and is currently not curable. Instead, osteoarthritis sufferers treat the condition with exercise, weight loss, assistive devices, medications, and possibly surgery when other options don’t work.

Now, new research suggests that a back-to-basics approach could prove to be a winning strategy; Improving Mitochondrial Health Through Urolithin Supplementation May Help Reduce Osteoarthritis Damage and Provide Welcome Joint Pain Relief.

The research team published preclinical results from a new study in aging cellwho reported the joint health benefits of the postbiotic gut microbiome urolithin A. They noted that for the first time a compound — Amazentis’ proprietary urolithin A supplement Mitopure — has been shown to improve mitochondrial health in an experimental model of osteoarthritis (OA). [1].

The results showed significantly improved mitochondrial health in human cartilage cells harvested from both healthy and osteoarthritic knee joints. Supplementation with Mitopure for eight weeks protected against progression of osteoarthritis disease in the experimental model.

So how does Mitopure work?

The answer lies within our mitochondria, living power generators in our cells that convert chemical energy into energy our cells can actually use to grow and repair, as well as all of the biological functions that are part of life. During this process, called cellular respiration, the mitochondria convert glucose and oxygen into an energy-rich molecule called ATP.

However, these generators lose efficiency as they age. This decrease in cellular energy leads to a decrease in cellular function, and in the case of the cells in our skeletal muscles, this can eventually lead to a progressive decrease in muscle function.

This decline in mitochondrial health is one of the causes of aging, and the change in mitochondrial function is linked to age-related problems in various tissues, including osteoarthritis. Our cells protect themselves from this degradation by stimulating the selective recycling of old or damaged mitochondria into new, healthy mitochondria—a process called mitophagy. This natural cleansing process also becomes less efficient with age, but urolithin A is a mitophagy activator that has been shown to benefit mitochondrial health in various scientific studies.

Mitopure – a proprietary form of urolithin A – works by supporting cells’ ability to renew their mitochondria during the aging process; Previous research has shown that Mitopure can improve mitochondrial health and muscle function in both the elderly and middle-aged [2]and this new research broadens its scope by extending these benefits to cells in key joints like the knee.

“Currently, there are no effective solutions to treat osteoarthritis, a condition that is painful and restricts the mobility of hundreds of millions of elderly people around the world,” said Dr. Martin Lotz, lead author of the paper and professor of molecular medicine at Scripps Research in California. “We have tested urolithin A in preclinical models of osteoarthritis and demonstrated that it has the potential to both reduce inflammation and improve mitochondrial health, suggesting that it may be a promising solution to support joint health and quality of life during the osteoarthritis period aging could be [3].”

What did the study show?

In research, Mitopure demonstrated two important beneficial effects on cartilage cells in both healthy donors and those suffering from osteoarthritis:

  • It significantly induced mitophagy – the recycling of aged and damaged mitochondria.
  • It significantly increased the activity of the mitochondria, which resulted in more energy being produced.

The second part of the study focused on the effect of two months of Mitopure supplementation on a model that mimics the symptoms of osteoarthritis.

  • Mitopure reduced the breakdown of joint tissue.
  • Mitopure supplementation reduced osteoarthritis-associated leg pain.
  • It exerted a mild anti-inflammatory effect in the model.
  • Better joint health after administration of Mitopure was associated with significantly improved mitochondrial health, including higher rates of mitophagy and increased regeneration of new, functional mitochondria.

“This study is important and exciting because it shows for the first time that urolithin A can improve mitochondrial health in living joint tissue,” said Davide D’Amico, first author of the publication and R&D group leader at Amazentis. “It underscores the important role of mitophagy in maintaining healthy functioning joints throughout life [3].”

“It has been great to work with Scripps Research to expand the body of evidence for the health applications of urolithin A to joint health,” said Chris Rinsch, CEO and co-founder of Amazentis. “It’s exciting to see a compound and mechanism of action that benefits both muscles and joints. We remain committed to delivering products that are proven to have a meaningful impact on people’s health [3].”
