Have you ever woken up to strange noises from your knee joint or experienced pain when you put weight on it? Or perhaps you’ve lifted a grocery bag and heard a “crack” in your shoulder? Unfortunately, whether due to age or genetic factors, joint problems can arise over time.
In these situations, hyaluronic acid supplements can be extremely beneficial. Hyaluronic acid is a naturally occurring substance in the human body, particularly as a key component of the extracellular matrix (ECM).
Highly soluble, hyaluronic acid helps to hydrate and protect tissues from stress, tension, and potential injury. Thanks to its viscoelastic and plastic properties, it provides volume and support to subcutaneous tissues and offers effective lubrication at the joint level.
Additionally, as hyaluronic acid forms a reticular, volumetric structure, it acts as a cementing agent, providing shock absorption and protection against impact—making it essential for maintaining joint health.
Hyaluronic Acid Supplements: What Are They Used For?

Hyaluronic acid is a key component of connective tissue, particularly in its amorphous substance, which forms a dense gel where collagen and elastin fibers are suspended. These fibers play a crucial role in lubricating and protecting joints, as well as in hydrating and softening the skin.
Consider, for instance, a knee that suddenly stops functioning as it normally does. Why does this happen? There could be several reasons, but it’s likely linked to cartilage that has thinned and lost its natural qualities. This is often due to a reduction in the body’s natural production of hyaluronic acid and the depletion of its beneficial properties.
Hyaluronic acid serves several important functions:
- Lubrication
- Shock absorption
- Viscoelasticity and plasticity
- Anti-inflammatory and regenerative properties
- Protection against infectious agents
It’s clear that a deficiency in hyaluronic acid can lead to joint issues, such as osteoarthritis. This condition results from an imbalance in the normal cycle of cartilage degradation and regeneration, with hyaluronic acid playing a critical role in maintaining this balance.
Hyaluronic acid supplements: when are they needed?

There are several situations where hyaluronic acid supplementation can be particularly beneficial. Here are a few examples:
- Osteoarthritis: To nourish cartilage, reduce inflammation and pain, and improve joint mobility
- Post-traumatic recovery: To support healing after injuries
- Tendon issues: Especially beneficial for athletes dealing with tendon injuries
- Post-injection treatment: To extend the effects of joint injections
- Osteoporosis: To support bone health, especially when combined with vitamin D
These conditions can affect people at various life stages, from young athletes with sports injuries to middle-aged individuals with physically demanding jobs, elderly people experiencing tissue degeneration, or even younger individuals with a severe genetic predisposition.
In all of these cases, hyaluronic acid supplementation is a valuable support, either on its own or as a complementary treatment alongside other therapies prescribed by a specialist.
Hyaluronic Acid Supplements: formats
Hyaluronic acid can be taken in various forms:
- Oral: Tablets, capsules, sachets, solutions.
- Sublingual: An innovative method with numerous advantages, available only in Cartial D.
- Intra-articular injections: Direct injection into the joint.
Cartial D: an innovative supplement for joint health

Hyaluronic acid supplementation is typically taken orally through tablets, capsules, or solutions. However, the challenge lies in the fact that hyaluronic acid molecules are large macromolecules that struggle to pass through the intestinal barrier. In most cases, gastric juices break down these molecules in the stomach, eliminating them before they can be absorbed.
To ensure that hyaluronic acid reaches the joints, Cartial D uses an innovative technology called hydrolysis. This process allows the hyaluronic acid to be delivered directly to the synovial cells. The absorption of hyaluronic acid depends on its molecular weight and concentration, with sublingual administration further enhancing its absorption.
Cartial D features low molecular weight (40 KDa) and short chains, combined with an exceptionally high concentration (6%), which allows it to quickly reach the synovial cells within the joints. This enables Cartial D to effectively restore viscoelasticity, lubricate the joints, reduce inflammation, and alleviate pain.
Hydrolysis is a natural technique that uses water to break down large hyaluronic acid molecules into shorter chains, making absorption easier. In the case of Cartial D, absorption occurs primarily through the sublingual route, although it can also pass through the intestinal barrier if swallowed.
In addition to hydrolyzed hyaluronic acid, Cartial D contains the most bioavailable form of Vitamin D3, cholecalciferol, at a dose of 500 IU per ml. Vitamin D is essential for muscle development, maintenance, and strength, particularly in adolescents, athletes, and the elderly. Studies have shown that low levels of Vitamin D are linked to reduced muscle strength, and it also plays a key role in bone health.
Here’s a summary of Cartial D’s key features and benefits:
- Hydrolyzed Hyaluronic Acid: Optimized absorption via sublingual administration and enhanced intestinal permeability.
- High Concentration (6%) of Hyaluronic Acid for maximum effectiveness.
- Fast Action and Sublingual Absorption for rapid relief.
- Proven Effectiveness in joint health and pain relief.
- Vitamin D3: Promotes calcium and phosphorus absorption and supports muscle function.
- Targeted Benefits: Nourishing cartilage, restoring joint lubrication, reducing inflammation, and alleviating pain.
How to use Cartial D?
It’s important to take Cartial D correctly by following a few simple instructions:
- Dispense 11 sprays (1 ml) into the sublingual mucosa, once to three times a day
- Hold the gel under your tongue for 60 seconds before swallowing
Take it for three-month treatment cycles
Do Hyaluronic Acid Supplements really work?
Over the years, numerous testimonials have highlighted the real benefits of Cartial D in treating even severe conditions. One notable example is Francesco T. from Rome, who was scheduled for hip replacement surgery but has postponed it for the past three years. According to his specialist, Cartial D has allowed him to walk again and significantly reduced or eliminated the debilitating effects on his quality of life.
So, do hyaluronic acid supplements actually work? At Eidon Salus, we can confidently say that Cartial D is highly effective in:
- Reducing joint pain
- Enhancing mobility
- Eliminating or reducing inflammation
- Restoring the ability to resume sports and improving quality of life
- Improving muscle function
