En tant que personnes' S les modes de consommation soucieux de la santé continuent d’évoluer, la façon de manger pour la santé et la beauté est devenue une priorité essentielle pour les consommateurs. En conséquence, le marché chinois a vu l’émergence d’une gamme de nouveaux aliments ressources bénéfiques pour la santé ou possédant des propriétés fonctionnelles spécifiques. Les nouveaux aliments ressources se réfèrent àIngrédients alimentairesQui sont récemment développés, découverts ou introduits en Chine, n’ont pas d’habitudes alimentaires établies, et répondent aux exigences de sécurité alimentaire de base. L’acide hyaluronique (hyaluronan) est un nouveau membre de cette famille. Cet article passe en revue les mécanismes d’absorption orale et les avantages pour la santé de l’acide hyaluronique, présente des produits connexes d’acide hyaluronique oral provenant de divers pays, et fournit un soutien pour le développement de l’acide hyaluronique dans l’industrie alimentaire.

 

1 Introduction à l’acide hyaluronique Oral

Acide hyaluronique is a linear, high-molecular-weight acidic mucopolysaccharide composed of alternating units of D-glucuronic acid (GlcA) and N-acetylglucosamine (GlcNAc). Commercially available hyaluronic acid is typically its sodium salt, i.e., sodium hyaluronate. Hyaluronic acid is widely distributed in biological organisms, with high concentrations in joint cavities, skin, eye vitreous humour, cartilage, umbilical cord, and rooster combs [1]. In 1934, Meyer et al. from the United States first isolated this substance from the vitreous humour of cow eyes. Hyaluronic acid possesses unique functions such as skin moisturisation, nutrition, anti-aging, antibacterial and anti-inflammatory properties, wound healing promotion, joint function improvement, and drug delivery. It is a versatile and high-performance functional biochemical substance widely used in cosmetics, pharmaceuticals, biochemistry, and health foods.

 

Early hyaluronic acid was primarily extracted from human umbilical cords and chicken combs; however, limited raw material sources restricted production scale. With the continuous maturation of fermentation-based hyaluronic acid production technology, hyaluronic acid production has undergone a series of transformations from raw materials to technology, and hyaluronic acid has gradually evolved from an expensive ‘rare substance’ into a functional ingredient widely recognised by consumers.

 

As a natural component of living organisms, hyaluronic acid, though present in only 15 g in the normal human body, plays a crucial role in maintaining normal bodily functions and delaying aging. Hyaluronic acid content is highest during the embryonic stage, reaching 20 times that of adult tissues, and decreases gradually with age. If the relative hyaluronic acid content in the human body at age 20 is set at 100%, it decreases to 65%, 45%, and 25% by ages 30, 50, and 60, respectively. Hyaluronic acid levels also vary among individuals of the same age, with those suffering from premature aging showing significantly lower levels and exhibiting various signs of aging [2]. The conversion rate of hyaluronic acid in mammals is extremely high. A decrease in hyaluronic acid can lead to various issues such as arthritis, skin aging, increased wrinkles, and presbyopia [3]. Therefore, the level of hyaluronic acid in the body can be regarded as a measure of the degree of human aging. Currently, it is believed that oral supplementation of hyaluronic acid to replenish endogenous hyaluronic acid is an effective approach for beauty, health, and longevity.

 

In China, the primary application areas of hyaluronic acid are concentrated in the pharmaceutical, clinical diagnosis and treatment, and cosmetics industries, accounting for over 98% of total usage [4]. Its application in food is still in its infancy, with limited reports available. Research on the use of hyaluronic acid in food first emerged in Japan, where official institutions have affirmed the safety of both extraction and fermentation methods for producing hyaluronic acid. Animal experiments have shown that hyaluronic acid is non-antigenic, and potential allergic reactions to hyaluronic acid in the human body are negative [5]. Acute toxicity experiments on rats indicated that oral administration of 500 mg/kg body weight of hyaluronic acid showed no antigenicity, no allergic reactions, and no teratogenic, mutagenic, or carcinogenic effects [6]. Oral experiments have shown that hyaluronic acid is practically non-toxic [7]. Since hyaluronic acid is a natural component of the human body and hyaluronic acid produced by different processes has no species differences, oral administration of hyaluronic acid has a high safety profile.

 

À la fin des années 80,oral hyaluronic acid beauty and health supplements first appeared in Japan. The theoretical basis is that after oral administration, hyaluronic acid is digested and absorbed, increasing the precursors for hyaluronic acid synthesis in the body, thereby raising hyaluronic acid levels and concentrating them in skin tissue. This enhances the skin' S capacité de rétention de l’humidité, adoucit la peau et#39; S couche de kératine, et améliore l’élasticité de la peau tout en réduisant les rides [8-9]. Contrairement aux cosmétiques contenant de l’acide hyaluronique, qui n’agissent que sur la peau et#Pour assurer une hydratation locale, l’acide hyaluronique oral agit par la dégradation, l’absorption et la re-synthèse de l’acide hyaluronique exogène dans le corps, augmentant ainsi les niveaux d’acide hyaluronique endogène et obtenant des avantages globaux pour la beauté et la santé.

 

2 mécanisme d’absorption de l’acide hyaluronique Oral

To date, through subcutaneous, intramuscular, or intravenous administration, the local metabolism of hyaluronic acid in various tissues except the brain has been basically understood. However, due to the presence of endogenous hyaluronic acid, accurately measuring the absorption of exogenous hyaluronic acid is challenging, so pharmacokinetic studies on oral hyaluronic acid are still insufficient.

 

Jiang Qiuyan et al. [10] conducted an oral hyaluronic acid experiment in rats via gastric lavage, with a dose of 60 mg/kg body weight and a hyaluronic acid concentration of 0.6%. The experimental results showed a biphasic drug-time curve: a significant peak appeared approximately 2 hours after administration, followed by a decline in concentration between 2 and 4 hours, and a steady increase between 4 and 13hours. This phenomenon was explained as follows: the peak at approximately 2 hours was primarily due to the absorption of exogenous hyaluronic acid in a non-monosaccharide form by the body, while the peak after 4 hours was attributed to the degradation of exogenous hyaluronic acid into two monosaccharides, followed by their resynthesis within the body. After continuous oral administration of hyaluronic acid for 7 days and 30 days in rats, serum hyaluronic acid concentrations were measured. Compared with the control group, the free hyaluronic acid content in the skin was significantly increased after 30 days of continuous oral administration, indicating that hyaluronic acid can be concentrated in tissues with high hyaluronic acid content after oral administration and participate in the metabolism of hyaluronic acid in these tissues. Further animal experiments showed that after 30 days of oral administration of hyaluronic acid, the hyaluronic acid content in joint synovial fluid and skin was significantly increased in rats.

 

Hyaluronic Acid Powder

Lajos et al. [11] labelled hyaluronic acid with radioactive technetium and investigated its metabolism in Wistar rats and Beagle dogs. After 72 hours, the radioactivity in rat excreta decreased to 5%, with detectable radioactivity in blood, muscle, thyroid, and bone. Peak radioactivity was observed 4–6hours after oral administration, and both rats and dogs showed radioactivity in shoulder joint and spinal fluid 4 hours post-administration. These findings indicate that hyaluronic acid is absorbed by the body and distributed to organs and joints after oral administration.

 

The absorption, metabolism, and resynthesis of hyaluronic acid are complex biochemical processes, particularly the absorption process. Hyaluronic acid is a linear, straight-chain macromolecule, so its absorption mechanism cannot be explained using the conventional biochemical principles governing the absorption of spherical molecules. It is generally believed that the human body can only absorb macromolecules with a molecular weight (Mr) of approximately 10,000. However, for the absorption of polysaccharides, additional factors such as the spatial conformation of the substance, its water solubility, and whether it is easily hydrolysed in the intestine must also be considered. For hyaluronic acid, its excellent water solubility and linear molecular structure, which facilitates absorption, make its absorption in the human body possible. Animal experiments have confirmed this through oral absorption data in the stomach; the results indicate that absorption efficiency is correlated with the Mr of the administered dose, suggesting that hyaluronic acid may also be absorbed in non-monosaccharide forms after oral administration. Additionally, the absorption of hyaluronic acid in the body is also related to the final formulation of the food product. Since hyaluronic acid is a large molecular polymer, its disintegration and dissolution processes in the human body also influence its bioavailability.

 

3  Recherche sur l’efficacité de l’acide hyaluronique oral

3.1. - les conditions de travail Beauté et bienfaits pour la santé

The dermis of the human body is primarily composed of collagen. Skin aging is caused by changes in collagen, which are attributed to a reduction in hyaluronic acid, a component with hydrating properties. The content of hyaluronic acid in the human body is in a dynamic equilibrium process. In a healthy individual, there are both degradation and synthesis reactions of hyaluronic acid. As age increases, this dynamic equilibrium is gradually disrupted, leading to a decrease in hyaluronic acid content and the gradual appearance of aging signs. Therefore, oral supplementation of exogenous hyaluronic acid to increase its synthesis in the body has become a key strategy for delaying aging.

 

Pang Xiaoyang et al. [12] conducted human efficacy trials using a skin-moisturising and beauty product formulated with chicken comb extract and other ingredients. The product was administered once daily at a dose of 4 capsules for 30 days. Compared with their own baseline and the control group, the skin moisture levels of the test subjects were significantly improved. Yamamoto [8] conducted a human clinical study showing that after taking hyaluronic acid products (ECM-E) for 3–24 days, most test subjects had smoother and more moisturised skin, with aesthetic effects observed on the face and throughout the body.

 

Huaxi Furuida Biotechnology Co., Ltd. a mené un essai fonctionnel humain pour améliorer l’humidité de la peau. Le groupe d’essai et le groupe témoin étaient composés chacun de 52 participants, qui ont été administréshyaluronic acid capsules (20 mg per capsule) and placebo, respectively, twice daily at 3 capsules per dose, for 45 consecutive days. The results showed that skin moisture levels in the trial group significantly increased after the trial, with significant differences compared to pre-trial levels and significant differences compared to the control group. After taking hyaluronic acid capsules, all test indicators were within normal ranges, and no allergic reactions or other adverse effects were observed, confirming the safety and efficacy of this product.

 

3.2 amélioration de la fonction articulaire et de l’ostéoporose

Japanese Q.P. Company [13] conducted a double-blind trial with 37 volunteers aged over 40 years old in the United States, using a placebo as the control group. Participants were administered 200 mg of high-purity hyaluronic acid daily, for 8 weeks. Joint pain changes were evaluated using the Western Ontario and Ontario Osteoarthritis Index (WOMAC) score. The results indicated that hyaluronic acid effectively alleviated joint pain. Leneau et al. [14] also conducted related experiments, confirming that oral hyaluronic acid effectively alleviates arthritis symptoms and protects joint function.

 

Osteoporosis is the result of a long-term disruption of the balance between bone resorption and bone deposition. Stancikova et al. [15] studied the effects of oral administration of two Mr (1.62 × 10⁶ and 0.75 × 10⁶) and three doses (150, 500, 1000 μg/kg body weight) of hyaluronic acid on an ovariectomised osteoporosis animal model, After four weeks of continuous oral administration, all three high-Mr dose groups and the high-dose low-Mr group reduced the levels of bone resorption markers pyridinoline and deoxypyridinol in urine to normal levels, increased bone density, and the efficacy was dependent on the Mr and dose of orally administered hyaluronic acid.

 

3.3 réparation des lésions des muqueuses gastriques

Huaxi Furuida Biotechnology Co., Ltd. investigated the effects of oral hyaluronic acid on chronic gastric ulcers using a rat gastric injury animal model. The hyaluronic acid dose was 45 mg/kg, with potassium citrate bismuth (BPC) as the positive control at 45 mg/kg, and physiological saline (NS) as the negative control at 10 mg/kg. Ulcer area changes were measured as the ulcer index. After 5 days of administration, there was no significant difference in ulcer area between the hyaluronic acid group and the BPC group compared to the NS control group. After 10 days of administration, the ulcer areas in the BPC and hyaluronic acid groups were smaller than those in the NS control group (P < 0.05), indicating that hyaluronic acid promotes ulcer healing with effects similar to those of BPC, suggesting that hyaluronic acid has a protective effect on the gastric mucosa and can repair damaged gastric mucosa.

 

3.4 autres effets

With the increasing complexity and diversity of human health issues, research on the effects of oral hyaluronic acid has extended to many related fields, including promoting wound healing [16], improving cardiovascular function [17], alleviating symptoms of osteoarthritis [18], enhancing immune function [19], and promoting angiogenesis [20], all of which have yielded satisfactory results.

In Malaysia, I-deal Company launched beauty beverages containing hyaluronic acid.

 

It is evident that the use of hyaluronic acid in health supplements (health foods) and general foods is already widespread in countries such as Japan, the United States, and South Korea, and has been widely accepted by consumers.

 

4.5 Formulations de suppléments de santé à base d’acide hyaluronique

4.5.1 tablettes

Tablets are the earliest dosage form for hyaluronic acid health supplements. During production, they typically include other nutrients and excipients such as collagen, elastin, vitamin C, and crystalline cellulose. This dosage form is commonly found in products from Japan and the United States, typically targeting beauty, nutrition, and anti-aging functions.

 

4.5.2 gélules

Currently, capsules are the most common dosage form for hyaluronic acid health supplements available on the market. They are often combined with nutrients such as collagen, vitamins, chondroitin sulfate, and plant extracts. Soft capsules are generally more expensive, with the capsule containing a mixture of oily liquids, often including fat-soluble vitamins, lecithin, EPA, and hyaluronic acid, among other nutrients. Hyaluronic acid exists in a suspension state within the capsule. Products in this formulation are primarily targeted at beauty, nutrition, and anti-ageing health benefits.

 

4.5.3 liquides oraux

Des formulations liquides orales contenant de l’acide hyaluronique sont récemment introduites. L’acide hyaluronique étant dissous, il est absorbé et métabolisé plus rapidement après ingestion. Il est à noter que ces produits sont généralement positionnés à l’étranger pour des avantages de santé liés à la santé des articulations, tels que «Syno-Vital H2O» et «Synthovial 7».

 

4.5.4 préparations en poudre

Another recent trend is oral powder formulations containing hyaluronic acid, which are characterised by easy solubility and absorption. The oral efficacy of these products is often positioned for beauty and health, such as skin hydration, with examples including ‘Tong Ren Tang Hyaluronic Acid Marine Fish Collagen Peptide Powder,’ which has been approved for sale in China.

 

5 acide hyaluronique oligomerique

L’activité de l’acide hyaluronique étant liée à son poids moléculaire (Mr), les acides hyaluroniques ayant des valeurs Mr différentes peuvent avoir des activités complètement opposées. Par conséquent, les pays du monde entier ont commencé à se concentrer sur la dégradation et les produits de dégradation de l’acide hyaluronique, et ont intensifié les efforts de recherche et de développement sur l’acide hyaluronique de faible poids moléculaire etAcide hyaluronique oligomerique(acide oligo-hyaluronique). En particulier, l’acide oligo-hyaluronique est un fragment de molécules d’acide hyaluronique ayant un Mr inférieur à 10 000 et un compte de résidus monosaccharidique de 2-40 (typiquement 4-16). Ses propriétés diffèrent considérablement de celles de l’acide hyaluronique ordinaire [21]. Grâce à son Mr plus petit, l’acide oligo-hyaluronique présente des taux de dissolution plus rapides et une meilleure biodisponibilité.

 

Lorsque l’acide hyaluronique est hydrolysé en fragments plus petits, il est plus facilement absorbé dans les intestins. Après absorption, il est re-synthétisé en acide hyaluronique à des sites spécifiques sous l’action d’enzymes endogènes. Japan New Drug Co., Ltd. a étudié l’efficacité orale de l’acide oligo-hyaluronique avec Mr 3000. Les Participants ont reçu de l’acide hyaluronique par voie orale avec des doses quotidiennes de 50 mg et 100 mg. Les résultats ont montré que la teneur en humidité de la peau du groupe acide oligo-hyaluronique par voie orale était significativement plus élevée que celle des autres groupes, et les sujets et#39; Les ridules de la peau ont été réduites, avec une plus grande fermeté de la peau, le groupe recevant 100 mg présentant des effets plus prononcés. Par conséquent, les chercheurs ont conclu que, en utilisant un apport quotidien de 120 à 240 mg deAcide hyaluronique à poids moléculaire élevéPar exemple, grâce à une meilleure perméabilité des muqueuses du petit intestinal et à une absorption et une utilisation plus élevées de l’acide oligo-hyaluronique, l’apport quotidien peut être réduit à 50-100 mg.

 

6  Perspectives d’avenir

Currently, the variety and sales volume of health supplements containing hyaluronic acid are growing rapidly in both domestic and international markets. It is worth noting that currently available health supplements containing hyaluronic acid are primarily targeted at beauty, nutrition, and joint health. As research into the efficacy of oral hyaluronic acid continues to deepen, more new products with different functionalities are expected to emerge.
