Top vitamin questions1. Why do vitamins make my urine yellow?
The bright yellow color in urine occurs mostly from the B vitamin Riboflavin, B2. Over 95% of the B supplements sold today are synthetic. The body treats them as toxic and the kidneys have to excrete them as quickly as possible, thus producing yellow urine. In contrast, a whole-food B complexe provides all the benefits without the toxic side effects.
2. When do I take my vitamins?
Minerals can be taken any time of the day, with or without food. Water-soluble vitamins are better taken with food and earlier in the day. i.e., B complex can contribute to energy and may keep you awake at night if taken later in the day. The fat-soluble vitamins; A, D, E, and K have to be taken with meals that contain some fat. The fat-solubles need to be carried across the intestinal wall by dietary fat to be metabolized.
3. What type of Calcium should I take?
Knowing which ones are right for you can be confusing.
There are over 75 forms of calcium in nature. About 7 or 8 are available for purchase at your local stores. Calcium is considered to be absorbed mainly in its ionized form; calcium lactate, citrate, fulvate. The most commonly sold form of calcium available in stores is calcium carbonate. It is cheap to produce, unfortunately it has the lowest absorption ability of all calcium forms and consistantly can be contaminated with heavy metals.
4. What about vitamin D?
Sunlight is your ideal source of vitamin D. UV-B sunlight produces vitamin D on the skin. Unfortunately, we are "cave-dwellers" and don't receive adequate sunlight to produce optimal vitamin D levels. The 2nd-best answer is vitamin D3, (cholecalcifero). Vitamin D3 can be three times as effective as vitamin D2 in raising serum vitamin D and maintaining those levels in the body.
5. Who needs Fatty Acids?
How much, in what ratio, for how long?
Essential Fatty Acids (EFAs) have to be provided in the diet, hence the term "essential" The are 2 essential fatty acids: linoleic acid and linolenic acid.
