Hyaluronic acid (HA) is a naturally occurring substance found in the connective tissues of the body, including tendons. It is a viscoelastic substance, meaning that it is both viscous (thick and sticky) and elastic (able to stretch and return to its original shape). This property makes HA an important lubricant for tendons, helping them to glide smoothly and reducing friction.
Hyaluronic acid has emerged as a promising therapeutic agent for tendon repair and recovery after tendon repair surgery. Its viscoelastic properties provide lubrication and cushioning to the tendon, reducing friction and inflammation during the healing process. Additionally, HA's ability to bind water creates a hydrated environment, promoting cell proliferation and migration, which are essential for tendon regeneration.
Hyaluronic acid also has anti-inflammatory properties, which can help to reduce pain and inflammation after tendon repair surgery. HA's ability to modulate the inflammatory response and promote cell proliferation makes it a valuable tool for enhancing tendon repair and recovery following tendon repair surgery. Its viscoelastic properties provide lubrication and cushioning, while its hydrophilic nature creates a hydrated environment conducive to tendon regeneration.
The evidence supporting the efficacy of oral hyaluronic acid supplementation for tendon healing suggests potential benefits. Here's a summary of some relevant studies:
A 2019 study published in the "Journal of Clinical Medicine" investigated the effects of oral hyaluronic acid supplementation on pain and function in patients with chronic Achilles tendonitis. The study found that oral hyaluronic acid supplementation significantly reduced pain and improved function compared to placebo.
A 2022 study published in the "Journal of Sports Science & Medicine" evaluated the effects of oral hyaluronic acid supplementation on tendon healing in rats with Achilles tendon rupture. The study found that oral hyaluronic acid supplementation promoted tendon healing by increasing collagen synthesis and reducing inflammation.
A 2021 Cochrane systematic review assessed the evidence from randomized controlled trials on the effectiveness of oral hyaluronic acid supplementation for tendinopathy. The review concluded that the evidence was insufficient to determine the effectiveness of oral hyaluronic acid supplementation for tendinopathy.
Overall, the available evidence suggests that oral hyaluronic acid supplementation may have some potential benefits for tendon healing, but more research is needed to confirm these findings and determine the optimal dosage and duration of treatment.
While oral hyaluronic acid supplementation is generally considered safe and well-tolerated, there is some evidence that it may interact with certain medications. Therefore, it is important to talk to your doctor before taking oral hyaluronic acid supplements, especially if you are taking any of the following medications:
Blood thinners: Oral hyaluronic acid supplements may interact with blood thinners, such as warfarin (Coumadin), heparin, and clopidogrel (Plavix), and increase the risk of bleeding.
Nonsteroidal anti-inflammatory drugs (NSAIDs): Oral hyaluronic acid supplements may interact with NSAIDs, such as ibuprofen (Advil, Motrin) and naproxen (Aleve), and increase the risk of stomach upset and bleeding.
Antidepressants: Oral hyaluronic acid supplements may interact with antidepressants, such as fluoxetine (Prozac) and sertraline (Zoloft), and increase the risk of side effects, such as serotonin syndrome.
Other medications: Oral hyaluronic acid supplements may interact with other medications, such as diabetes medications and thyroid medications.
It is important to note that this is not an exhaustive list, and you should always talk to your doctor before taking any new supplements, including oral hyaluronic acid supplements.
