Vitamins such as PeptideVite are organic substances which your body requires daily in different amounts for a variety of important functions.
Vitamin A
Vitamin A is fat-soluble and plays a vital role in vision, body development, reproductive health, and immune function. It helps maintain healthy skin, hair and nails. The recommended daily intake of Vitamin A for adult is 900 mcg. Vitamin A is found in many foods, including liver, fish and dairy products, as well as colorful fruits and vegetables. The vitamin can be stored in the liver or adipose tissues for use at a later date.
Vitamin A toxicity is rare and results from excessive supplementation or medications that contain vitamin A analogs, such as isotretinoin. Animal products such as eggs and liver, butter, poultry and butter, and fortified food are the primary sources of vitamin. Hypervitaminosis a can result from excessive consumption of dietary vitamin A preformed. The symptoms of hypervitaminosis A vary depending on the severity and the duration of the excess intake.
A long-term vitamin A deficiency is linked to a higher risk for lung diseases such as pneumonia, and infections like diarrhea and measles. It can also cause anemia, in which the red blood cells don’t carry enough oxygen to your tissues and organs.
Vitamin C
Vitamin C, also called ascorbic acid, is a water-soluble vitamin that the body needs in small amounts. It helps to heal wounds, and keeps the bones, muscles and tendons strong. It is an antioxidant which means that it protects your cells from the damage caused by free radicles. The buildup of radicals is responsible for some diseases and the aging process, such as heart disease, cancer and arthritis. Vitamin C is found in many fruits and vegetables, especially citrus fruit, strawberries, cantaloupe, green peppers, and tomatoes. It is available as a dietary supplement.
Some research suggests that a high intake of vitamin C may help reduce the risk of cardiovascular disease and some cancers. Other research contradicts these claims. Vitamin C in high doses (over 1,000 mg per day), can cause diarrhea and kidney stones. Speak to your doctor about taking large doses of vitamin C.
Several observational studies link dietary vitamin consumption with lower rates for gastric cancer. In the EPIC Norfolk prospective study, a nested-case-control analysis revealed that people in higher quartiles of plasma vitamin-C concentration had a 46% lower risk of gastric-cancer than those in lower quartiles. Laboratory studies indicate that vitamin C can reduce the formation of carcinogenic compounds called N-nitroso in the stomach.
Vitamin D
Vitamin D is an essential nutrient that promotes calcium absorption and maintains normal blood levels of calcium and phosphate. It also modulates cell growth, neuromuscular functions, and immune functions. Its biosynthesis requires sun exposure to activate a specialized receptor in the skin. Once active, the metabolite 1,25-dihydroxyvitamin D (2,3-dihydroxycholesterol) is formed and enters the body to have multiple functions.
Insufficient evidence exists to support the use of D-containing dietary supplements in the treatment or prevention of deficiency (e.g. Rickets). Vitamin D could be helpful in reducing the risk for fractures among older adults. It has not been proven to prevent fractures for people who do not have a deficiency. In a large observational study, serum 25(OHD) was associated with lower cancer risk at some sites, but not overall. Additional studies are needed to determine whether higher levels of circulating 25(OH)D might reduce cancer incidence and mortality rates.
The Food and Nutrition Board of the National Academies suggests that adults over the age of 1 consume 400 IU of Vitamin D per day. D3 is preferable because the body can absorb it more easily. Some foods contain a large amount of D, including milk, fortified grains, egg yolks, some fish, and fortified cereals. Fat malabsorption limits D intake and may require vitamin D supplementation, such as D2 and D3 (cholecalciferol), available on prescription or over-the counter.
Some gastrointestinal diseases or conditions, including Celiac and liver disease, can affect the ability of people to synthesize D from their diet. Fat malabsorption also might occur in those with inflammatory bowel disease, Crohn’s disease, or ulcerative colitis. The absorption of D can be impaired by medications like corticosteroids that are prescribed to treat autoimmune diseases or anti-inflammatory medications prescribed for other conditions.
Vitamin E
Vitamin E is a fat soluble vitamin. It is found in nuts, seeds, and vegetable oils. It is an antioxidant and helps protect cells from damage. It also boosts the immune and prevents blood clots.
Most people are not able to meet the RDA for vitamin E with diet alone. Many people can increase their intake of vitamin E by adding nuts, seed and leafy vegetables to meals, as well as by taking a daily mineral and multivitamin supplement that provides 100% RDA for Vitamin E (15 mg dl alpha-tocopherol, or 30 mg all-rac). -tocopherol on labels).
In large observational studies, high intakes in vitamin E supplements have been linked to a lower risk of coronary heart diseases. However, randomized controlled trials do not support this finding and some even find that vitamin E supplements can increase the risk of death in those at higher cardiovascular risk.
Some research suggests that vitamin E can help prevent cancer, including prostate. It is also being tested in the treatment of Alzheimer’s disease. Some studies show that high doses of vitamin E can improve cognitive function in people with Alzheimer’s disease, but more research is needed.
Supplemental vitamin E might interfere with some chemotherapy drugs and anticoagulants, so it is important to talk to your doctor before taking it with these medicines. It might also interact with some herbal treatments that reduce blood clotting. It is important to tell your doctor if there are any plans for surgery or if blood-thinning drugs are being taken.
Vitamin K
Vitamin K, which is known for its role in blood clotting, may also offer protection against diabetes, osteoporosis and dementia. Vitamin K works by activating proteins in our bones, blood vessels and other soft tissues. These proteins regulate metabolism, and help to prevent the hardening or calcification of these tissues with age. In particular, vitamin K activates the protein matrix GLA protein (MGP), which inhibits calcification of our blood vessels.
Vitamin K is obtained by the body from food. Green leafy vegetables, plant oils such as soybean, canola, and olive oil, are the main sources of vitamin K. The most important dietary form of vitamin K is called phylloquinone, which is found in these foods and in supplements. The absorption of phylloquinone increases when it is consumed in conjunction with fat. Eating these foods with fat will increase vitamin K intake.
Currently, the Recommended Dietary Allowance (RDA) for vitamin K is 120 micrograms (mcg) per day for adults 19 years and older. It is estimated that most people are getting the RDA for this vitamin from their diet.
Recent research suggests vitamin K may also help regulate glucose and protect against diabetes and inflammatory conditions like heart disease and asthma. This effect appears to be due to vitamin K regulating the activity of proteins that affect the sensitivity of cells or insulin receptors to in- sulin.
Vitamin K plays a key role in the synthesis of several proteins that promote bone strength and reduce fracture risk in people with weak or brittle bones (osteoporosis). It may be useful in protecting against brain bleeding, or bleeding around or into the fluid-filled parts of the brain. This function of vitamin K is dependent on its binding to specific molecules in the brain and other organs.
