Homocysteine is an amino acid. Amino acids are the building blocks of proteins. When proteins break down, elevated levels of amino acids like homocysteine may be found in the bloodstream. Having elevated levels of homocysteine in the blood (hyperhomocysteinemia) is associated with atherosclerosis and blood clots. It is not possible to get homocysteine from the diet. It must be made from methionine, another amino acid that is found in meat, fish, and dairy products.
People take blood thinners to increase the amount of time it takes blood to form a clot. They don't actually thin the blood. Thick blood would be blood that clots too fast. Oftentimes heart patients have to take blood thinners (anticoagulants such as coumarin) because they already have a tendancy to clot too quickly.
