Folic acid is a synthetic derivative of folate and is acquired by dietary supplementation. [25] Multi-vitamin dietary supplements contain folic acid as well as other B vitamins. Non-prescription folic acid is available as a dietary supplement in some countries, and some countries require the fortification of wheat flour, corn meal or rice with ...
Folic acid supplements have little established role in cancer chemotherapy. [60] [61] The supplement of folinic acid in people undergoing methotrexate treatment is to give less rapidly dividing cells enough folate to maintain normal cell functions. The amount of folate given is quickly depleted by rapidly dividing (cancer) cells, so this does ...
Sometimes referred to as "food folates", these vitamers are characterized as pteroylpolyglutamates and contain between one and six additional glutamate molecules compared to folic acid. [3] Folic acid, chemically described as pteroylmonoglutamic acid, is another vitamer of vitamin B 9. Though rarely found in minimally processed foods, it is the ...
The study found a significant effect on heart health in a low-salt diet, and a small effect due to omega-3 and folic acid supplements. [43] This analysis supports the results of two early 2018 studies that found no conclusive benefits from multivitamins for healthy adults.
Folinic acid should be distinguished from folic acid (vitamin B 9). However, folinic acid is a vitamer for folic acid and has the full vitamin activity of this vitamin. Levofolinic acid and its salts are the 2S-form of the molecule. They are the only forms of the molecule that are known to be biologically active.
Fortification is present in common food items in two different ways: adding back and addition. Flour loses nutritional value due to the way grains are processed; enriched flour has iron, folic acid, niacin, riboflavin, and thiamine added back to it. Conversely, other fortified foods have micronutrients added to them that don't naturally occur ...
The greenhouse effect occurs when greenhouse gases in a planet's atmosphere insulate the planet from losing heat to space, raising its surface temperature. Surface heating can happen from an internal heat source (as in the case of Jupiter ) or come from an external source, such as its host star .
The cause of tropical sprue is not known. [2] It may be caused by persistent bacterial, viral, amoebal, or parasitic infections. [5] Folic acid deficiency, effects of malabsorbed fat on intestinal motility, and persistent small intestinal bacterial overgrowth may combine to cause the disorder. [6]
