People have long recognized that vitamins are essential for maintaining health, and people have realized that food has the ability to heal. The ancient Egyptians knew that feeding a patient’s liver would help cure night blindness, a disease caused by vitamin A deficiency. In 1749, Scottish surgeon James Lind discovered that citrus foods helped prevent scurvy in sailors. Scurvy can cause poor wound healing, bleeding gums, severe pain and even death. But sometimes medical discoveries are ignored. In the early 20th century, when scurvy disrupted two expeditions to the Antarctic, popular medical theory believed that scurvy was caused by "contaminated" canned food. In fact, scurvy is caused by vitamin C deficiency.
Essential nutrients for good healthIn order to be healthy and functioning properly, we need seven essential nutrients. The human body cannot produce these essential nutrients by itself. They must usually be ingested and absorbed from our food. The basic nutrients are carbohydrates, protein, fat, fiber, vitamins, minerals and water. Oxygen and sunlight are also essential for the maintenance of human life, but they are not usually classified as nutrients. Carbohydrates are converted into sugar for energy. Protein is composed of amino acids, which help to strengthen muscle mass. Fat, also called lipid, is used by the body for energy and exercise. Vitamins are necessary to sustain life and fight disease and even death. These minerals are inorganic non-living elements found in all cells of the human body. They regulate body fluids, promote growth, and help tissues. Of course, water is essential for digesting food and moving waste. Two thirds of the human body is water. Water is the main component of blood and helps human tissues absorb nutrients. People survive for weeks or even months without food, but they cannot survive for days without water.
What is vitaminVitamins are organic, lively compounds, vital to life and health. When it comes to vitamins, they are highly essential for the normal growth and development of the human body. From the day of conception to the entire life, vitamins support the chemical reactions that produce skin, bones and muscles. On the actual seance, vitamins are one of the essential nutrients for the healthy maintenance of the cells, tissues and organs that make up the human body. Vitamins enable the body to utilize the chemical energy provided by carbohydrates, fats and proteins. And process food. Small amounts of vitamins are necessary for metabolism, tissue building and regulating body processes. Science classifies 12 vitamins and approximately the same amount of minerals as "essential nutrients."
Vitamins are water-soluble or fat-soluble. Water-soluble vitamins (such as vitamin C and B complex) are easily destroyed by cooking, air and light. Fat-soluble vitamins, such as vitamins A, D, E, and K, are soluble in fat and can be stored in the body which means they are not in anyway easily destroyed by cooking, air and light.
In most cases, we get vitamins from the food we eat. A balanced diet is the primary source of vitamins needed for human health. But there are other sources of vitamins. For example, there are microorganisms in the intestines, also known as "gut flora", which can produce vitamin K and biotin. One form of vitamin D is synthesized in the skin under the natural ultraviolet wavelengths of sunlight. The human body can make some vitamins from the food it eats. For example, vitamin A is produced from β-carotene. In another example, niacin is produced from the amino acid tryptophan.
Why do we need vitaminsWe know that vitamin deficiency can lead to poor health and cause disease. Vitamin deficiencies and mineral deficiencies can lead to goiter, scurvy, osteoporosis, impaired immune system, abnormal cell metabolism, certain forms of cancer, symptoms of premature aging, and poor mental health. Many diseases are caused by chronic or chronic lack of vitamins. Defects in the metabolic conversion of vitamins may also cause diseases. Sometimes, when excess fat-soluble vitamins accumulate in the body, we may also contain too much vitamins. This is called hypervitaminosis.
What are vitamin supplementsIdeally, a balanced diet containing a variety of fresh, unprocessed foods is a reliable source of essential vitamins. But the modern diet is inadequate in many ways. Your diet may be insufficient. Because modern agricultural technology has exhausted the soil of minerals and vitamins. Vitamin supplements provide essential nutrients every day. It is also recommended that dietary supplements be used for specific health conditions.
Do I need vitamin supplements?Our modern diet is not balanced and cannot provide us with all the vitamins our body needs to stay healthy. Many doctors and nutritionists believe that it is wise for all adults to take vitamin supplements. The Journal of the American Medical Association recommends vitamin supplements. Needless to say, we know nothing about nutrition. Researchers in the field of nutrition are still discovering new discoveries about substances that can build and support a healthy body and fight disease. But we use vitamin supplements as insurance.
What's in vitamin supplements?In order to maintain good health, a typical basic multivitamin multimineral supplement contains the following vitamins:
Vitamin A (retinyl acetate and β-carotene)
Vitamin C (ascorbic acid)
Vitamin D (Cholesterol Calciferol)
Vitamin E (such as d-α tocopheryl succinate)
Thiamin (vitamin B-1) (as Thiamin hydrochloride)
Riboflavin (Vitamin B-2)
Vitamin B-6 (pyridol hydrochloride)
Vitamin B-12 (cyanocobalamin)
Pantothenic acid (calculated as d-calcium pantothenate)
Most multi-vitamin multi-mineral supplements also include the minerals calcium, iron, magnesium and zinc. The content of vitamin supplements is measured in units of IU or milligrams or micrograms of mcg. A microgram is one thousandth of a milligram. The label on the bottle also shows the content of each vitamin (as a percentage of the recommended daily value).
What is a custom proprietary vitamin supplement?Many manufacturers create customized vitamin supplement products by adding other nutrients that are known to help maintain health. You may find some of these supplements: calcium, iron, phosphorus, iodine. Magnesium, zinc, selenium, copper, manganese, sodium, potassium, boron, PABA (para-aminobenzoic acid), choline bitartrate, inositol, alfalfa, L-lysine, DL-methionine, L-leucine, L-cystine, L-isoleucine, L-phenylalanine, L-arginine, L-histidine, L-threonine, L-valine, wheat germ, papain, Chlorophyll, Citrus Bioflavonoids, Peppermint, Ginkgo Biloba, Coenzyme Q-10, Large Leaf Flavonoids, Deodorant Garlic, Echinacea, Spirulina, Chlorella, Klamath Lake Spirulina, Grape Seed Extract, Watercress, Parsley, kelp and soy lecithin.
These other ingredients are known to have nutritional value in maintaining health, but they have not been as well studied as the basic "essential" vitamins. Proprietary vitamin supplement combinations are more expensive. Sometimes there are too many other ingredients and you have to take multiple capsules to meet the minimum daily requirement.
Can you take too much vitaminIf you want to take vitamin supplements to keep your body healthy, you should consider some precautions. People who are allergic to milk, wheat and soy should avoid vitamin supplements containing these ingredients. If you are pregnant, nursing, taking any medications or planning any medical procedures, please inform your doctor of the supplements you are using. If you suffer from diabetes or hypoglycemia, please avoid taking chromium, because chromium affects your insulin and blood sugar. Long-term high intake of certain vitamins will exceed the recommended daily intake, which may cause nervousness, anxiety and rapid heartbeat. After all, this is an artificial compound, not a food-derived supplement.
In the United States, vitamin supplements are regulated as foods, not drugs. The US Food and Drug Administration (FDA) does not allow manufacturers to claim that the supplement can prevent, treat or cure any disease.

- Wheat germ oil and liver are good sources of vitamin E. Vitamin E is also called tocopherol. Vitamin E deficiency is very rare. Vitamin E is a powerful antioxidant that helps fight free radicals that damage cells in the body. Studies have shown that oxidative stress caused by free radicals may lead to premature cell aging. Vitamin D maintains good cardiovascular health, immune system and prostate health.
- The liver is a good source of vitamin B12. Vitamin B12 is also called cyanocobalamin. Vitamin B12 deficiency can cause megaloblastic anemia. Vitamin B-12 is a naturally occurring B-complex vitamin that can promote the health of the circulatory system and nervous system. It supports energy metabolism by cooperating with enzymes (such as amino acids) involved in nutrient breakdown. It is involved in the synthesis and renewal of DNA.
- Alfalfa is a good source of vitamin K. Vitamin K is also called benzoquinone. Vitamin K helps blood clotting, and the lack of vitamin K can cause blood to ooze.
- The liver is a good source of vitamin B5. Vitamin B5 is also called pantothenic acid. A deficiency of vitamin B5 can cause paresthesias. B5 supports the function of the adrenal glands.
- A good source of vitamin B7 in the liver Vitamin B7 is also called biotin. Vitamin B7 deficiency can cause dermatitis and enteritis. Biotin is essential for the metabolism of protein and carbohydrates and the production of hormones and cholesterol.
- Rice bran is a good source of vitamin B6. Vitamin B6 is called pyridine alcohol. Vitamin B6 deficiency can cause anemia.
