Applications | Shaanxi BLOOM Tech Co., Ltd

 

Scientific research has shown that proteomics are more easily absorbed and utilized by the body after being broken down into small molecule peptides, especially when the molecular weight is ≤ 500Da. Flaxseed itself is rich in plant proteomics and alpha linolenic acid, making it a high-quality natural source of raw materials. When oligopeptides are extracted through enzymatic hydrolysis technology, not only does it improve solubility, but it also makes it easier for active ingredients to enter the metabolic cycle. The absorption efficiency of oligopeptides is 30% to 60% higher than that of free amino acids, and it does not increase the burden on the digestive system. This characteristic makes it a preferred solution for rapid proteomics supplementation in the field of sports nutrition, especially suitable for postoperative recovery and elderly people.

 

At present, the purity of flaxseed peptide products on the market can reach 80%~98%, with specifications covering different concentration ratios such as 10:1, 20:1, 30:1, etc. The main production areas are concentrated in Guyuan, Ningxia, Xi'an, Shaanxi, Baoji, Shaanxi and other places. The product is mainly in powder form and can be used in various dosage forms such as granules, tablets, capsules, etc. It can also be directly added to liquid foods such as beverages and dairy products.

Flaxseed Peptide uses | Shaanxi BLOOM Tech Co., Ltd

1. Reduce the 'three highs':
It has outstanding performance in regulating blood lipids, blood pressure, and blood sugar, and can be regarded as a nutritional tool for the "three highs" population.
Lowering blood lipids: It can inhibit the absorption of cholesterol. The human body needs bile acids to assist in digesting and absorbing cholesterol, and soy peptides (similar to flaxseed) stimulate duodenal secretion during digestion, causing significant contraction of the gallbladder, promoting bile acidification, disrupting cholesterol absorption, and allowing cholesterol to be discharged into the intestine with bile, reducing the absorption and utilization of cholesterol by the colon, thus achieving the goal of reducing cholesterol.

At the same time, it can accelerate the metabolism of LDL (bad cholesterol) in the liver, convert it into bile and excrete it from the body, reduce blood lipids and viscosity, and enhance the level of HDL (good cholesterol).

Lowering blood pressure: can inhibit the activity of angiotensin-converting enzyme (ACE). ACE in blood vessels can convert angiotensin I into angiotensin II, which causes peripheral blood vessels to contract and blood pressure to rise. After inhibiting ACE activity with oligopeptides, it can prevent vasoconstriction and achieve the effect of lowering blood pressure. It is worth noting that it does not have a hypotensive effect on normal blood pressure, so it has a significant effect on patients at risk of cardiovascular disease, and is harmless to normal individuals, making it safe and reliable.

Hypoglycemia: oligopeptides can promote insulin secretion, regulate blood sugar in human body, and improve the symptoms of diabetes. It can repair pancreatic beta cells, promote normal insulin secretion, and restore normal circulation of sugar and fat metabolism; It can also activate dormant receptors, allowing insulin to bind to the receptors normally and increasing the sensitivity of human tissues to insulin. Clinical practice has proved that oligopeptides have a very significant effect on diabetes patients, and even there is a saying that "taking them for a period of time can get rid of insulin worries".

In addition, oligopeptides have a slow inhibitory effect on alpha glucosidase, further assisting in blood glucose management.

2. Enhance immunity:
Immune regulation is one of the most widely recognized benefits. Oligopeptides can stimulate the proliferation of lymphocytes in the body, enhance the phagocytosis of macrophages, and improve the activity of NK cells (natural killer bioplasts), thus improving the ability of the body to resist external pathogen infection and reducing the incidence rate.
Mechanistically, oligopeptides enhance immunity by stimulating the production of cytokines in the body. The deeper function is that peptides can stimulate thymus regeneration.

The thymus is the most important organ for manufacturing the immune system, responsible for producing and promoting the maturation of T bioplasts and lymphocytes. The thymus begins to atrophy at the age of 12, shrinks to the size of only a raisin at 40, and completely disappears at 60. Oligopeptides can restore the atrophied thymus to its original size, while also allowing the body to produce more T bioplasts, new antibodies, red and white blood cells to resist diseases and cancer.

Oligopeptides can also directly enter bioplasts, fuse with the bioplast membrane, and prevent bacterial and viral invasion. Simultaneously improving the permeability of intermediate metabolic membranes (gastrointestinal mucosa, capillary wall, alveoli, meninges, red blood cell wall, glomerular basement membrane), effectively absorbing nutrients and defending against pathogen invasion.

3. Antioxidant and anti fatigue properties
Antioxidant: The amino acids in flaxseed oligopeptides can inhibit the production of free radicals, increase the activity of superoxide dismutase (SOD) and glutathione peroxidase in the body, inhibit lipid peroxidation, eliminate hydroxyl radicals, and help reduce tissue oxidation and maintain overall health. This characteristic gives it practical significance in delaying aging.
Anti fatigue: Flaxseed peptide can directly repair damaged skeletal muscle bioplasts during exercise, maintaining the consistency of skeletal muscle bioplast structure and function.

Simultaneously increasing testosterone secretion, promoting proteomics synthesis, and reducing post exercise blood urea nitrogen (BUN) levels are beneficial for alleviating post exercise fatigue. According to user feedback, after three months of persistent use, "it's not that exaggerated and stimulating sense of energy, but a light and energetic feeling from the inside out.
Oligopeptides can also promote the synthesis and release of neurotransmitters in the brain, which can help alleviate anxiety and depression and improve sleep quality. It can promote the secretion of melatonin precursor, which has a good effect on insomnia, allowing people to enter deep sleep and be energetic during the day.

4. Muscle growth and weight loss shaping
Muscle building: Oligopeptides can promote the absorption of amino acids by muscle bioplasts, enhance the synthesis of DNA and RNA, promote the absorption of extracellular proteomics, and increase the storage of sugars and nitrogen elements. The ultimate result is to promote the growth of muscle bioplasts, increase cell size, enhance muscle strength and exercise ability. Dr. Rudman's clinical trial showed that after six months of use, lean meat increased by 8.8% in 12 elderly individuals.
It can also enhance the activity of brown adipose tissue membrane proteomics, promote fat breakdown, increase the conversion rate of norepinephrine, reduce inhibition of lipase, thereby promoting fat breakdown.

Effectively reducing excessive body fat percentage in the body, while maintaining muscle weight unchanged, achieving the goal of healthy weight loss. The majority of the reduced fat is located in the abdomen, buttocks, and inner upper arm, which are the most stubborn areas of fat accumulation.
The weight loss mechanism also includes: firstly, promoting the burning of fat in the body and converting it into the energy needed by the body; Secondly, peptides bind to receptors in adipocytes and undergo a series of enzymatic reactions, leading to the metabolism of adipocytes (i.e. lipolysis); Thirdly, peptides have an antagonistic effect on insulin, preventing fat accumulation in the body.

5. Bones and joints
Oligopeptides can promote the generation of a large number of osteoblasts, inhibit osteoclasts, enhance bone density, and prevent osteoporosis. It can effectively promote the growth of new bones, enhance the absorption and utilization of calcium by bones, thereby increasing bone density, preventing fractures, and effectively improving various joint discomforts.

Oligopeptides have a regulatory effect on common diseases in the elderly, such as neck, shoulder, waist, and leg weakness, femoral head necrosis, arthritis, and calcium deficiency.
