Niacin has is not only needed by the body for healthy skin caring for the nervous system an more but has also been prescribed for its effectiveness at lowering LDL and raising HDL cholesterol levels (Niacin acts in the breakdown of all major foods). With so many sources available for niacin the question arises whether a natural source or chemically manufactured one better for the body. There has been much debate to answer this question; however, to receive the most from your vitamin supplement the healthier choice is the natural choice.
It has been shown to be more economical to produce vitamin supplements from chemical sources yet as Dr. Jenkins stated in one study "there are no natural food components in most USP (United States Pharmacopoeia) vitamin formulas (Diet Factors Affecting Nutrient Absorption and Metabolism)". The method that the body employs to receive nutrients is partially dependant on their interaction with each other and the natural sources provide for this interaction with greater ease. One study provided that "niacinamide is 3.94 times more absorbed in the blood than USP niacinamide and 1.7 times more retained in the liver than isolated USP niacinamide (Bose)". As a secondary to natural vitamins the body receives co-factors such as, for example, "carrot powder contains bioflavonoid like beta carotene which is a precursor to Vitamin A" (Agrawal). The downside to synthesized vitamins is that do not contain the antioxidants found in natural vitamins (Agrawal).

Vitamin E is an organic chemical (meaning a complex compound containing the element carbon), but if you are referring to the "food" sense of those words it may be either organic or nonorganic depending on its source and how it was processed. Note: in chemistry the terminology is organic and inorganic while in "foods" the terminology is organic and nonorganic. The terminologies are completely unrelated.

Calvin cycle is mostly used for the CO2 fixation by the aototrophic bacteria as carbon source.
Seaweed collects and concentrates many minerals from the ocean making it a good source of nutrients such as iodine and calcium. It is also high in fiber, low in fat, and vitamin rich.
the polysaccharides in the potato (i.e. long chain starches) can be broken down by cooking into short chain starches that can be digested by enzymes in the human gut to glucose, which provides nutritional valuethe polysaccharides in in wood (e.g. cellulose, pectin) cannot be broken down by cooking or by enzymes in the human gut, so it provides no nutritional value

Cellulose does have nutritional value. It is a major source of the needed fiber in our diet.
Multivitamin supplements are sold at drugstores, nutrition stores, but are more reasonably priced a large discount stores such as Walmart. GNC is also a good source, though a little more expensive.
good source of vitamin c
Out pellets are regurgitated food. It is a good nutritional source for animal feed.
An alternative label source suggested was to scan the original product packaging for nutritional information.
Any medium must supply certain basic nutritional requirements that allow cells to grow. These include a carbon source, an energy source, nitrogen, minerals, vitamins, and water.
Well, the source of Hazelnuts are, but it's got alot of sugar and milk chocolate in it.
Host. Host.
The organism from which a parasite obtains nutritional needs is called a host. The host is a food source and a home for the parasite.
The primary function of disaccharides is as a nutritional source of monosaccharides. Many of the sugars found in foodstuffs are disaccharides.
Not really. Look into a nutritional database to find out:http://www.nutritiondata.com/
