Hyaluronan for nutrition - Nutrihyl®

an active ingredient of biotechnological origin

Sodium hyaluronate (hyaluronan, sodium salt of hyaluronic acid) is a non-sulfated glycosaminoglycan. It is a polysaccharide with a non-branched chain composed of disaccharide units formed from D-glucuronic acid and N-acetylglucosamine, held together by β (1 3) bonds. These disacharide units are joined together by β (1 4) bonds forming a negatively charged poly (β-D-glucuronate-[1 3]-β-N-acetyl-D-glucosamine-[1 4]). The molecular formula of β-sodium-D-glucuronate-[1 3]-β-N-acetyl-D-glucosamine is [C14H20O11NNa]n, where n = 250 - 5000.

Sodium hyaluronate is a substance found in all vertebrates, mainly in connective tissue such as cartilage, bone, skin etc. and body fluids. From this point of view it is a non-toxic, non-cytotoxic, non-immunogenic and non-mutagenic substance.

soluble in water. Sodium hyaluronate with a molecular weight higher than 1MDa forms a viscose solution at the concentration of 1%. Viscosity further increases with higher concentration (2% sodium hyaluronate forms gel). Due to the presence of glucuronic acid in the structure, hyaluronate forms salts with different cations. Salts with simple cations such as sodium, potassium calcium, magnesium etc. are fully soluble in water in contrast to salts formed with polymeric or hydrophobic cations. limited solubility in alcohol-water mixture. Soluble in the mixture if the concentration of alcohol is below 40%. insoluble in non-polar solvents

Storage: store in originally sealed packaging in a cool and dry place

The influence of Nutrihyl® on experimental adjuvant arthritis

We studied the influence of Nutrihyl® on the development of adjuvant arthritis induced by the suspension of thermally killed mycobacterium in incomplete Freud adjuvans in rats. Nutrihyl® with different molecular weight was administered per orally by sound in various dosages.

Nutrihyl® with molecular weight of more than 1MDa significantly reduces swelling of the hind leg joint after arthritis development (14th day p < 0.05, 21st and in 28th day p < 0.001) is active at a very low concentration (0.1 mg/kg of the body mass is sufficient)

Distribution of per orally applied Nutrihyl®

To evaluate the mechanism of per orally applied hyaluronan, it is essential to start with observation of its pharmacokinetics. Looking in the literature, we will find many references about hyaluronan pharmacokinetics after intravenous and also topical application, but very little is known about its pharmacokinetics after per oral application. 1-5 An article about pharmacokinects of technetium labeled hyaluronan was published. In this article, the authors describe the biological test with 99m technetium labeled hyaluronan (Nutrihyl®) at rats, where only 5% of the labeled HA was absorbed. Over 90% of radioactivity appeared in feces after 72 hours. The radioactivity was measured in blood, muscles, salivary glands and bone as early as after 30 minutes, and peaked 4-6 hours in all non-alimentary tissues examined after oral administration. There were transient increases in radioactivity in shoulder joints and vertebrae 4 hours after oral administration of HA. These results demonstrate that HA is absorbed and distributed to organs and joints after a single oral administration. 6-7

The influence of Nutrihyl® and chondroitin sulphate combination on joints after knee surgery

The study was made in the university orthopaedic clinic in Prague with 27 patients recovering from knee surgery. The group was treated with the mixture of Nutrihyl® and chondroitin sulphate per orally for 90 days. The efficiency of the treatment was expressed for the following parameters: swelling and painfulness of the joint and movement capability. The disposition of the patient was evaluated before and after the treatment by a patient (subjective finding) as well as by a doctor (clinical finding). The overal results are presented in Fig. 2.

The influence of Nutrihyl and chondroitin sulphate combination on joints after knee surgery 

The effect of chondroitin sulphate in a dose which is markedly below the therapeutic dose is most probably insignificant as it was proven in our study on race horses and therefore we can conclude that the effectiveness of the preparation used for this study can be assigned to Nutrihyl® only.

The influence of Nutrihyl® on the state of knee joint in ice-hockey players

The study was made in the Musculosceletal Institute in Prague with 24 ice-hockey players of the premier league. The group was treated for 90 days during the sport season. The efficiency of the treatment was expressed for the following parameters: joint movement, muscle strength, joint stability and intra-articular problems. The disposition of the sportsman was evaluated before and after the treatment by a doctor. The overal results are presented in Fig. 3.

The influence of Nutrihyl® on experimentally cause osteoporoses

Osteoporoses was experimentally caused in laboratory female rats by ovarectomy. We have observed the effect of p.o. applied Nutrihyl® with different molecular weight and at different dosages on parameters characterizing bone degradation and bone density. The experiment with ovarectomized rats simulates women after menopause.

  • in the group of rats which underwent the ovarectomy and had not been treated by Nutrihyl® the content of pyridinoline and deoxypyridinoline ( markers of bone degradation) in the urine increased to 158% of the content compared to the control group in which the ovarectomy had not been done. In the group which underwent the ovarectomy and had been administrated by Nutrihyl® with a molecular weight of more than 1.3MDa the content of pyridinoline and deoxypyridinoline only increased to 106%. Nutrihyl® significantly decreased the secretion of bone degradation markers into urine.
  • Nutrihyl® administrated to ovarectimized rats significantly reduced bone density decrease (96% of the control) in comparison to ovarectomized rats, which were not given Nutrihyl® ( 91% of the control).
  • the ability of Nutrihyl® to eliminate the symptoms of osteoporoses is higher molecular weight of Nutrihyl® (molecular weight > 1,3MDa)


The influence of Nutrihyl® on skin and hair

Our findings 8 showed that Nutrihyl® activates nitric oxide (NO) synthesis. The content of nitrate and nitrite, the „metabolites" of NO, in blood serum is increasing after per oral use of Nutrihyl®. It is known that NO has positive effect on wound healing, hair growth and other processes in skin 9-11. These findings suggest that per orally applied Nutrihyl® could have a positive effect of overall state of skin and hair thus could become an ideal nutritional supplement to a topical cosmetic care for ageing and damaged skin.
