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.
Fat, in addition, plays a vital role in the digestion of vitamins. Vitamins A, D, E, and K are fat soluble vitamins, meaning they need fat in order to be absorbed into the body. 3. Carbohydrates. Carbohydrates are the main energy source of the body. They are chains of small, simple sugars that are broken down and enter the body as glucose. Glucose is essential for the body, as it is the preferred source of energy in our brain, heart and central nervous system. For this reason, your diet should consist of at least 45 to 65 percent carbohydrates. Carbohydrates are found in many foods. However, you should stay away from sweet foods with excess sugar.
