Here is a read on b-12 and other stuff in "horse" matters....about b-12
PHOSPHORUS FOR MUSCLE ENERGY PRODUCTION
All Species
A high level of athletic performance requires efficient utilization of large amounts of energy to produce muscular contraction. The main nutrients from which cells extract energy are oxygen and the foodstuffs - carbohydrates, fats and proteins. Inside cells the foodstuffs react chemically with oxygen under the influence of various enzymes and energy is released. This energy is used to form ATP.
ATP is the ultimate energy source used by working muscles. ATP contains three phosphate molecules. During exercise ATP is converted to ADP which releases large amounts of energy to fuel muscle contraction. In this process one of the phosphate molecules is utilised. In order for muscle contraction and exercise to continue, ATP stores must by immediately replenished. High-energy phosphates stored in the muscles as creatine phosphate provide energy to quickly replenish these ATP supplies.
Foliphos contains Butafosfan, a highly available form of phosphorus. Regular injections of Foliphos during training provide a ready source of phosphorus that can be incorporated into high-energy phosphate complexes in the body tissues, particularly muscles.
FOLIC ACID AND VITAMIN B12 FOR RED BLOOD CELL PRODUCTION
Two B-Complex vitamins, Folic Acid and Vitamin B12 in combination, are essential for red blood cell production in the bone marrow. Red blood cells carry oxygen to body tissues where it is used in chemical reactions that convert food into energy to fuel cell functioning. Oxygen is essential for the process of "oxidative phosphorylation" by which 90% of the ATP within the body is produced. Remember that ATP is the phosphorus-containing molecule that powers muscle cells during exercise.
A low red blood cell count, or anaemia, decreases the oxygen carrying capacity of the blood and leads to loss of stamina, fatigue and poor performance. A deficiency of either folic acid or Vitamin B12 causes macrocytic (large cell) anaemia.
