An essential nutrient is a nutrient required for normal body functioning that either cannot be synthesized by the body at all, or cannot be synthesized in amounts adequate for good health (e.g. niacin, choline), and thus must be obtained from a dietary source. Some categories of essential nutrients include vitamins, dietary minerals, essential fatty acids, and essential amino acids. Different species have very different essential nutrients. For example, most mammals synthesize their own ascorbic acid, and it is therefore not considered an essential nutrient for such species. It is, however, an essential nutrient for human beings, who require external sources of ascorbic acid (known as Vitamin C in the context of nutrition). Many essential nutrients are toxic in large doses (see hypervitaminosis or the nutrient pages themselves below). Some can be taken in amounts larger than required in a typical diet, with no apparent ill effects. Linus Pauling said of vitamin B3, (either niacin or niacinamide), "What astonished me was the very low toxicity of a substance that has such very great physiological power. A little pinch, 5&_160;mg, every day, is enough to keep a person from dying of pellagra, but it is so lacking in toxicity that ten thousand times as much can [sometimes] be taken without harm."[1] The body's requirements vary widely. At one extreme a 70&_160;kg human contains 1.0&_160;kg of calcium but only 3&_160;mg of cobalt.

There has been some debate over the years about how much of each of the specific omega-3s were necessary for human health. Currently, the USRDA says that an “acceptable” intake is 1100mg of total omega-3s for women and 1600mg for men.

6. changing ph levels in a hydroponics system
October 12, 2009
Adjusting pH Levels in a Hydroponics SystemInstructions for adjusting pH levels:pH control is essential for stimulating vigorous plant growth. Nutrient solution pH that is too high (basic) or too low (acidic) cannot be properly absorbed by plants. Incorrect nutrient solution pH can slow growth, and can also lead to sickly plants and low yields. The pH scale measures acidity or alkalinity on a scale of 0 to 14. Below seven the pH is acidic. Above seven the pH is alkaline. 7.0 is neutral. The best pH for plant growth is generally in the range of 5.5 to 6.5; which is slightly acidic. There are se... (read more)

8. Why You Need a Fish Oil Vitamin
October 02, 2009
Did you know the fish oil vitamin, as some people call it, is actually a different kind of nutrient, although the definitions are very similar? Vitamins are organic compounds required in tiny amounts by an organism.
The compounds cannot be synthesized by the organisms, so they must be obtained from the diet. This definition leaves a lot of gray area that can be downright confusing to the average person. Sometimes, it is easier to just refer to them all as vitamins, but the term is not generally used to refer to essential fatty acids.
