Pure Vegan Homocysteine Control Spray is a unique, orally administered, fast-acting formula that may support the cardiovascular system by maintaining normal homocysteine levels. Homocysteine is a toxic amino acid formed in the body when other amino acids in your blood are broken down by normal body processes. High blood levels of homocysteine have been linked to a higher risk of heart and vessel disease, and are considered even more of a threat to heart health than high cholesterol. In addition, high levels of homocysteine combined with excessive serum cholesterol can damage the cardiovascular system. Recent studies have shown that elevated homocysteine levels may be an independent risk factor for the development of heart disease, brain disease and stress. Homocysteine also damages cells that line the veins or arteries and stimulates the development of scar tissue in the damaged area.
