The table below shows the prices for letters over 1 ounce (round up the weight, e.g. if it is 2.1 ounces, use 3 ounce price). If your letter is more than 3.5 ounces, OR is larger than the maximum size of a regular envelope (11 1/2 x 6 1/8), then you would use large envelope pricing.
Overview. Vitamin B12, also called cobalamin, is one of 8 B vitamins. All B vitamins help the body convert food (carbohydrates) into fuel (glucose), which is used to produce energy.These B vitamins, often referred to as B complex vitamins, also help the body use fats and protein.B complex vitamins are needed for healthy skin, hair, eyes, and liver.ll B vitamins are water soluble, meaning that the body does not store them. Vitamin B12 is an especially important vitamin for maintaining healthy nerve cells, and it helps in the production of DNA and RNA, the body's genetic material.
2. A general characteristic of the water-soluble vitamins is that they must be consumed frequently. 3. A general characteristic of the fat-soluble vitamins is that excesses are eliminated from the kidneys so they are unlikely to create a problem of toxicity. 4.An explanation why B vitamin deficiencies lead to lack of energy is that many of them function as coenzymes needed for energy metabolism.5. general characteristic of the fat-soluble vitamins is that excesses are eliminated from the kidneys so they are unlikely to create a problem of toxicity. 4.
