Atro-phex Folic acid is a type of B vitamin that’s key for cell growth and metabolism. Studies show that many people in the U.S. don’t get enough folic acid.Don’t be confused by the different terms folate and folic acid. They have the same effects. Folate is the natural substance in whole foods. Folic acid is the synthetic version in supplements and fortified products. Phenylethylamine‚ or PEA‚ is a neuromodulator‚ which is responsible for the transmission of norepinephrine and dopamine. This chemical

What are anabolic-androgenic steroids (AAS) in specific Oxandrolone and how do they physiologically affect an athlete. Only a small percentage of people can make it to the level of being classified a professional athlete. The excessive psychological and physiological demands are not easy to live up to as strains‚ pressure and requirements are constantly placed on the individual. Injuries are an athlete’s worst nightmare‚ they cause set backs and can ruin an athletes form

Anemia (ah-NEE-mee-ah) is a medical condition that occurs when a person does not have enough red blood cells. Red blood cells are important because they contain hemoglobin‚ a protein that carries oxygen from the lungs to the body’s muscles and organs. The body requires oxygen for energy. Therefore‚ when you are anemic‚ you may feel tired mentally and physically. Symptoms of anemia include:7‚8‚9‚10 · Fatigue · Weakness · Shortness of breath · Dizziness or fainting · Pale skin‚ including decreased
