Abstract

Formulation comprising one or more amino acid(s), preferably packaged in sachets.

Description

Title of the invention: Formulation comprising one or more amino acid(s)

[0001] The present invention relates to the technical field of food formulations comprising combinations of compounds.

[0002] For the purposes of this description, an interval described by the expression "between [...] and [...]" includes the bounds. For example, the interval "between 1 and 2" includes the two values ​​"1" and "2" as well as all values ​​that are both strictly greater than 1 and strictly less than 2.

[0003] In the context of this description, the term "approximately" preceding a numeric value means that the value can be changed by plus or minus 10%. In the specific case of a numeric value being an interval limit, the term "approximately" means that the lower limit can be increased or decreased by 10% and / or the upper limit can be increased or decreased by 10%. It is also possible to omit the term "approximately" preceding a numeric value.

[0004] Dietary supplements containing amino acids have become popular in recent years due to their essential role in health and general well-being. Amino acids, which are the building blocks of proteins, play a fundamental role in various biological processes, such as muscle building, tissue regeneration, and immune system function.

[0005] Traditionally, they are classified into two categories: essential amino acids, which the body cannot synthesize and must therefore obtain through food, and non-essential amino acids, which the body can produce.

[0006] Among the essential amino acids are leucine, isoleucine and valine, which are particularly prized by athletes for their beneficial effects on physical performance and muscle recovery.

[0007] In addition, certain supplements containing amino acids, such as glutamine and creatine, are often used to improve endurance, reduce fatigue and increase muscle mass.

[0008] They can also play a role in mental health by influencing neurotransmitter production and helping to regulate mood. The quality of products on the market can vary considerably, making caution necessary when choosing these supplements.

[0009] There are a number of compounds that are important for the functioning of the body.

[0010] For example, hyaluronic acid is an essential molecule in the human body, recognized for its many benefits. Naturally present in the skin, In joints and connective tissues, it plays a crucial role in hydration and lubrication. By attracting and retaining water, hyaluronic acid helps maintain skin elasticity and firmness, thus reducing the appearance of wrinkles. In joints, it acts as a shock absorber, facilitating movement and decreasing friction. N-Acetyl-Glucosamine is a direct precursor of hyaluronic acid.

[0011] For example, collagen is a fundamental protein found in the body, representing approximately 30% of total protein. It is the main component of connective tissues, such as skin, bones, tendons, and cartilage, and plays a crucial role in the structure and strength of these tissues. By providing elasticity and firmness to the skin, collagen helps prevent premature aging and maintain a youthful appearance. In addition, it promotes wound healing and supports joint health by reducing friction.

[0012] For example, elastin is an essential protein that provides elasticity and resilience to the connective tissues of the human body, including the skin, blood vessels, and ligaments. Its main function is to allow tissues to return to their original shape after being stretched or contracted. This is particularly crucial in areas such as the skin, where elastin helps maintain firmness and elasticity, thus reducing the appearance of wrinkles and sagging skin. In addition, in blood vessels, it contributes to the regulation of blood pressure. Elastin production decreases with age, highlighting the importance of this protein for maintaining healthy skin and good vascular function.

[0013] There is a need to have such formulations available to promote the endogenous production of such compounds that are important for the human body.

[0014] In the prior art, a number of investigations have been carried out.

[0015] Thus, in application WO202306894 filed on behalf of NV NUTRICIA, a spray-drying process is described for manufacturing powders with a high fat content, including nutritional products such as infant formula, growing-up milk, or medical products. These products may contain amino acids.

[0016] Furthermore, in application WO202044163 filed on behalf of APR APPLIED PHARMA RESEARCH SA, a solution is described for normalizing amino acid metabolism in individuals following a low-protein diet supplemented with amino acids. The objective is to treat associated metabolic disorders, such as phenylketonuria (PKU), using modified-release formulations of amino acids. This technology is presented as improving nitrogen balance, preventing muscle loss, and stabilizing glucose and insulin levels.

[0017] Finally, in application WO2016088078 on behalf of PROFESSIONAL DIETETICS SPA, compositions based on amino acids (glycine, L-proline, L- alanine, L-valine, L-leucine and L-lysine). This composition is presented as stimulating the biosynthesis of elastin and collagen, essential for the recovery of fibroelastin in cutaneous connective tissues.

[0018] These formulations are not entirely satisfactory.

[0019] Surprisingly, it was discovered by the applicant that improved formulations could be made.

[0020] The invention relates to a formulation, preferably a food formulation, comprising at least glycine or one of its salts.

[0021] It has been found that glycine deficiency is often a limiting factor for collagen synthesis, and that supplementation can significantly improve this process. Furthermore, it has also been found that a high concentration of glycine sustainably stimulates collagen synthesis, particularly for cartilage regeneration.

[0022] In one embodiment, the mass percentage of glycine, relative to the total mass of said formulation, is between about 25% and about 75%, preferably between about 30% and about 70%, preferably between about 35% and about 65%, preferably between about 40% and about 60%, preferably between about 45% and about 55%, preferably between about 48% and about 52%, preferably about 51%.

[0023] In one embodiment, said formulation further comprises at least proline or one of its salts, preferably proline or one of its salts, preferably L-proline.

[0024] It has been discovered that proline plays a role in stabilizing collagen fibers, which is useful for tissue regeneration.

[0025] In one embodiment, the mass percentage of proline, relative to the total mass of said formulation, is between about 5.0% and about 14.9%, preferably between about 6.0% and about 13.9%, preferably between about 7.0% and about 12.9%, preferably between about 8.0% and about 11.9%, preferably between about 8.9% and about 11.9%, preferably between about 10% and about 11%, preferably about 10.2%.

[0026] In one embodiment, said formulation further comprises at least lysine or one of its salts, preferably the acetate salt, preferably L-lysine or one of its salts, preferably L-lysine acetate.

[0027] It has been discovered that lysine is an essential amino acid for the synthesis and strengthening of collagen fibers.

[0028] In one embodiment, the mass percentage of lysine, relative to the total mass of said formulation, is between approximately 5.0% and approximately 14.9%, preferably between approximately 6.0% and approximately 13.9%, preferably between between about 7.0% and about 12.9%, preferably between about 8.0% and about 11.9%, preferably between about 8.9% and about 11.9%, preferably between about 10% and about 11%, preferably about 10.2%.

[0029] These quantities have been carefully selected to meet the body's needs while also ensuring a sufficient amount of lysine is available. Indeed, a higher quantity of lysine must be added because it reacts with proline in the formulation, meaning that some lysine will ultimately not be available to meet the body's needs. A technical overdose is therefore anticipated.

[0030] A synergy between glycine, proline and lysine has been discovered, which guarantees increased production of stable and resistant collagen fibers, thus strengthening the firmness and elasticity of tissues.

[0031] It has been discovered that these amino acids are very rapidly absorbed by the body.

[0032] This means that once ingested, they quickly enter the bloodstream and are available for the synthesis of compounds important to the human body.

[0033] In one embodiment, said formulation further comprises at least vitamin C.

[0034] It has been discovered that vitamin C, which is a powerful antioxidant, also plays a key role in collagen synthesis.

[0035] In one embodiment, the mass percentage of vitamin C, relative to the total mass of said formulation, is between about 1.2% and about 3.7%, preferably between about 1.5% and about 3.5%, preferably between about 1.7% and about 3.2%, preferably between about 2.0% and about 3.0%, preferably between about 2.2% and about 2.7%, preferably between about 2.4% and about 2.6%, preferably about 2.5%.

[0036] In one embodiment, said formulation further comprises at least N-acetyl-D-glucosamine.

[0037] In one embodiment, the mass percentage of N-acetyl-D-glucosamine, relative to the total mass of said formulation, is between about 2.5% and about 7.5%, preferably between about 3.0% and about 7.0%, preferably between about 3.5% and about 6.5%, preferably between about 4.0% and about 6.0%, preferably between about 4.5% and about 5.5%, preferably between about 4.8% and about 5.2%, preferably about 5.1%.

[0038] It has been discovered that the addition of N-acetyl-D-glucosamine further enhances the effectiveness of the synergy mentioned above, by promoting the synthesis of collagen and hyaluronic acid.

[0039] In one embodiment, said formulation further comprises at least zinc or one of its salts, preferably zinc gluconate.

[0040] It has been discovered that zinc is important for collagen production and the protection of cells against free radicals.

[0041] In one embodiment, the mass percentage of zinc, relative to the total mass of said formulation, is between about 0.3% and about 0.9%, preferably between about 0.3% and about 0.8%, preferably between about 0.4% and about 0.8%, preferably between about 0.5% and about 0.7%, preferably between about 0.5% and about 0.6%.

[0042] In one embodiment, said formulation further comprises at least glutamine or one of its salts, preferably L-glutamine.

[0043] It has been discovered that glutamine enables the repair and maintenance of tissues, particularly muscles and skin.

[0044] In one embodiment, the mass percentage of glutamine, relative to the total mass of said formulation, is between about 5.0% and about 15.0%, preferably between about 6.0% and about 14.0%, preferably between about 7.0% and about 13.0%, preferably between about 8.0% and about 12.0%, preferably between about 9.0% and about 11.0%, preferably between about 9.6% and about 10.4%, preferably about 10.2%.

[0045] In one embodiment, said formulation further comprises at least arginine or one of its salts, preferably arginine hydrochloride, arginine base or arginine alpha-ketoglutarate, preferably L-arginine hydrochloride, L-arginine base or L-arginine alpha-ketoglutarate, preferably L-arginine base or L-arginine alpha-ketoglutarate, preferably L-arginine base.

[0046] It has been discovered that arginine promotes blood circulation and collagen production, and plays a role in tissue healing and repair.

[0047] In one embodiment, the mass percentage of arginine, relative to the total mass of said formulation, is between about 3.5% and about 10.6%, preferably between about 4.3% and about 9.9%, preferably between about 5.0% and about 9.2%, preferably between about 5.7% and about 8.5%, preferably between about 6.4% and about 7.8%, preferably between about 6.8% and about 7.4%, preferably about 7.2%.

[0048] These quantities have been carefully selected to meet the body's needs while also ensuring a sufficient amount of arginine is available. Indeed, arginine must be added in a larger quantity because it reacts with proline in the formulation, meaning that some arginine will ultimately not be available to meet the body's needs. A technical overdose is therefore anticipated.

[0049] It has been discovered that arginine is also very rapidly absorbed by the body. This means that once ingested, it quickly enters the bloodstream and is available for the synthesis of compounds important to the human body.

[0050] Furthermore, it is known that arginine is difficult to formulate with lysine, whereas these two amino acids are very important for the effectiveness of the formulation. Quite surprisingly, it has been discovered that a selection of particular forms of these amino acids makes them compatible in terms of formulation.

[0051] This is how L-lysine acetate was selected, and L-arginine base was also selected in particular.

[0052] These compounds are compatible and allow for optimization of the formulation.

[0053] The synergy mentioned above is supported and enhanced by the presence of vitamin C, N-acetyl-D-glucosamine, zinc, glutamine and arginine, which optimize the synthesis process and protect cells against oxidative stress.

[0054] A number of excipients may also be added.

[0055] In one embodiment, said formulation further comprises at least one flavor, preferably pineapple flavor, preferably having a mass percentage, relative to the total mass of said formulation, of between about 1.6% and about 4.7%, preferably between about 1.9% and about 4.3%, preferably between about 2.2% and about 4.0%, preferably between about 2.5% and about 3.7%, preferably between about 2.8% and about 3.4%, preferably between about 3.0% and about 3.2%.

[0056] In one embodiment, said formulation further comprises at least one stabilizer, preferably maltodextrin, preferably having a mass percentage, relative to the total mass of said formulation, of between about 1.2% and about 3.5%, preferably between about 1.4% and about 3.3%, preferably between about 1.6% and about 3.1%, preferably between about 1.9% and about 2.8%, preferably between about 2.1% and about 2.6%, preferably between about 2.3% and about 2.4%.

[0057] Humidity can cause powders, particularly hydrophilic amino acids such as L-glutamine, to clump together. It has been observed, in general, that the inclusion of maltodextrin made it possible to guarantee a fluid and homogeneous texture.

[0058] In one embodiment, said formulation further comprises at least one sweetener, preferably steviol glycosides from Stevia, preferably having a mass percentage, relative to the total mass of said formulation, of between about 0.1% and about 0.3%, preferably between about 0.1% and about 0.3%, preferably between about 0.1% and about 0.3%, preferably about 0.2%.

[0060] In one embodiment, said formulation further comprises at least one colorant, preferably beta-carotene, preferably having a mass percentage, relative to the total mass of said formulation, of between about 0.1% and about 0.3%, preferably between about 0.1% and about 0.2%.

[0061] In one embodiment, said formulation further comprises at least one first emulsifier, preferably sucrose esters of fatty acids, preferably having a mass percentage, relative to the total mass of said formulation, of between about 0.1% and about 0.2%.

[0062] It has been discovered that sucrose esters of fatty acids help to ensure better absorption of the active ingredients.

[0063] In one embodiment, said formulation further comprises at least one second emulsifier, preferably sunflower lecithin, preferably having a mass percentage, relative to the total mass of said formulation, of between about 0.04% and about 0.1%, preferably between about 0.05% and about 0.1%, preferably between about 0.06% and about 0.1%, preferably between about 0.07% and about 0.1%, preferably between about 0.08% and about 0.1%, preferably between about 0.08% and about 0.09%, preferably about 0.09%.

[0065] It has been discovered, surprisingly, that guar gum allows for a prolonged release of the active ingredients.

[0066] In one embodiment, the formulation is in a form chosen from the group consisting of tablets, capsules, powders in sachets, liquids, sprays, energy bars, candies, infusions, dissolvable plates or films, jellies, syrups, ampoules, lozenges and gums.

[0067] In one embodiment, the formulation is in the form of a powder in a sachet.

[0115] Example 3: Lysine inclusion and stability

[0116] The following two formulations were prepared. [Tables 2] Formulation 1, sachet Formulation 2, sachet Quantity per sachet (mg) Quantity per sachet (mg) Glycine 5075.73 5075.73 L-Proline 1014.75 1014.75 L-Glutamine 1014.75 1014.75 L-Arginine base 719.73 719.73 L-Lysine Hydrochloride 603.9 0 L-Lysine Acetate 0 603.9 N-Acetyl-D-Glucosamine 509.85 509.85 Vitamin C 252.45 252.45 Zinc gluconate 59.04 59.04 Natural pineapple flavor 314.82 314.82 Maltodextrin 238.59 238.59 Stevia steviol glycosides (sweetener) 19.8 19.8 Citric acid 19.8 19.8 Beta-carotene 17.82 17.82 Sucrose ester of fatty acids 14.85 14.85 Guar gum 14.85 14.85 Sunflower lecithin 8.91 8.91 Table 2: Comparative formulations

[0117] Formulation 1 comprises L-Lysine hydrochloride, while formulation 2 comprises L-Lysine acetate

[0118] The stability of these formulations has been studied.

[0119] The observations concerning formulation 1 are as follows: - After only a few days of storage, a significant browning of the powder was observed, as well as a tendency to agglomerate; - During the test at 40°C and 75% humidity for 30 days, color changes and agglomeration of the powder were observed, the pH also decreased, suggesting an acidic reaction in the mixture.

[0120] The same tests were applied to formulation 2, and the latter proved to be perfectly stable. No browning or agglomeration was observed, and pH stability was maintained throughout the test.

[0121] In conclusion, the substitution of L-Lysine hydrochloride by L-Lysine acetate results in a drastic improvement in stability.

[0122] Finally, without wishing to be bound by any technical explanation, it seems that L-lysine hydrochloride is particularly incompatible with L-proline.

[0123] Furthermore, it should be noted that other tests have also demonstrated that a formulation according to the invention, for example according to example 1, is, all other things being equal, more stable using L-arginine base than using L-arginine hydrochloride.
