Incredible Health Benefits
In view of the above-mentioned properties and effects of proanthocyanidins, the health benefits of 95% Proanthocyanidins Powder produced by us are as follows:
1. Improves blood circulation: Proanthocyanidins can strengthen capillaries, arteries, and veins. Therefore, it has the effect of reducing swelling and dissipating blood stasis. Capillary resistance decreases and permeability increases, making it easier for cells to absorb nutrients and eliminate waste. Proanthocyanidins can scavenge water-soluble and fat-soluble free radicals in cell membranes, thereby inhibiting the process of releasing certain enzymes that destroy capillary walls.
2. Moisturizes the skin: Proanthocyanidins make more vitamin C work, and vitamin C is easier to complete all its functions (including collagen production). Proanthocyanidins are attached to collagen and can prevent the destruction of collagen-destroying enzymes. Proanthocyanidins can not only help collagen fibers to form a cross-linked structure but also help repair damage caused by excessive cross-linking caused by injuries and free radicals. Excessive cross-linking can suffocate and harden connective tissues, which can cause wrinkles and premature aging of the skin. Proanthocyanidins also protect the human body from sun damage, promote the healing of psoriasis, and prolong life. Proanthocyanidins are also excellent additives for topical skin creams.
3. Eliminates cholesterol: proanthocyanidin combined with vitamin C can decompose cholesterol, convert it into bile salt, and excrete it. Proanthocyanidins accelerate the decomposition and elimination of harmful cholesterol.
4. Protects the heart: Proanthocyanidins help restore skin elasticity, but also help maintain the normal function of joints, arteries, and other tissues (such as the heart). The vascular system is responsible for blood flow, delivering blood to all cells and tissues. Therefore, no matter from the perspective of long-term and short-term effects, proanthocyanidins are the best cardioprotective agents found so far. Procyanidins also inhibit the production of histamine, thereby reducing inflammation and helping arteries resist the impact of mutagenic factors that cause cardiovascular disease.
5. Anti-allergic inflammation: Proanthocyanidins can relieve allergies, asthma, bronchitis, hay fever, rheumatoid arthritis, sports injuries, pressure sores, etc. When the human body becomes inflamed, it releases a compound called histamine, which can trigger the symptoms of various diseases mentioned above. Proanthocyanidins inhibit the enzymes needed to produce histamine, preventing the production of histamine, and thus reducing inflammation. Proanthocyanidins are well-known histamine inhibitors, but they do not block other enzymes. Athletes love proanthocyanidins for their ability to make joints flexible, repair collagen in connective tissues, and reduce edema. Proanthocyanidins have also been reported to improve joint inflammation in many people.
6. Improve hypoxia: hypoxia refers to the long-term lack of oxygen, which causes irreparable damage to the body. Lack of oxygen in the elderly may cause mental and physical problems. Therefore, proanthocyanidins scavenge free radicals and inhibit capillary rupture and damage to surrounding tissues. It can also improve the state of capillaries, enhance blood circulation to the brain, and the brain can get more oxygen.
