Hyaluronic acid (HA) has become one of the most popular ingredients in the beauty and health industry in recent years. It is often used in skincare products, to improve joint health, and even as a dietary supplement. But is this just a trend, or is there real scientific evidence supporting its benefits? Let's examine what the latest scientific research says about hyaluronic acid consumption.
💧What is hyaluronic acid?
Hyaluronic acid is a naturally occurring substance in the body that belongs to the glycosaminoglycan class. It is important for the structure of the skin, joints, and connective tissue, as well as for retaining moisture. One of its key properties is the ability to attract and hold up to 1,000 times its weight in water. As we age, natural HA production decreases, which can make the skin drier, less elastic, and joints less flexible.
💧Benefits of hyaluronic acid for the skin
Scientific studies show that hyaluronic acid consumption can improve skin moisture levels and reduce the visibility of wrinkles. Regular use of oral supplements has been linked to increased skin elasticity, reduced roughness, and overall better skin hydration. Additionally, HA is also used externally in serums and creams, which can help replenish moisture and give the skin a plumping effect.
💧Supporting joint health
HA is an essential component of synovial fluid, ensuring smooth joint movement and reducing friction between bones. For people with osteoarthritis, hyaluronic acid supplements may help reduce pain and improve mobility. Some studies suggest that regular consumption can contribute to cartilage maintenance and inflammation reduction.
🤔Other possible benefits
Besides supporting skin and joint health, hyaluronic acid may have other positive effects:
- Wound healing – HA promotes tissue regeneration and may help reduce inflammation.
- Eye hydration – commonly used in eye drops to combat dry eye syndrome.
- Reducing acid reflux symptoms – preliminary studies suggest that HA supplements may help protect the esophageal lining and ease reflux symptoms.
⚠️Safety and usage recommendations
Hyaluronic acid is considered safe for most people, but it's important to pay attention to product composition. The recommended dosage typically ranges from 120–240 mg per day. While side effects are rare, pregnant and breastfeeding women should consult a healthcare professional before using supplements.
🎯Conclusion
Hyaluronic acid is not just a short-term beauty industry trend. Its benefits for skin hydration, joint health, and other bodily functions are supported by scientific research. However, before choosing the most suitable form of intake, it is important to assess personal needs and consult with specialists.
