Due to the extreme complexity of stacking with proper consideration to demographics such as age, requirements, and gender, we have released a far more encompassing fit - The Supplement Guides
With FREE lifetime updates and authored by over a dozen researchers, it is the clearest guide to supplementation there is.
Supplements that modify levels of circulating lipoproteins in the blood (more commonly referred to as cholesterol). At least in regards to the risk for heart disease, you would want a reduction in LDL cholesterol and an increase in HDL cholesterol (no form of cholesterol is bad, but a relative increase in LDL to HDL is pretty common and increases the risk for problems).These supplements are those focused on cholesterol per se. There may be supplements that benefit heart health that are not related to cholesterol levels directly, and these would either be those that reduce atherosclerosis or reduce blood pressure (the page on circulation is a related topic).
Garlic can either be supplemented (in which the above dosage seems to be used in most studies on cholesterol) or it can be eaten directly where one would eat 0.5-1 cloves of garlic two to three times a day.
Garlic seems to reliably reduce both blood pressure as well as improve cholesterol, with a reduction in total cholesterol and LDL cholesterol both in the range of 10-15% and an increase in HDL cholesterol of around 10-15% with daily usage of garlic.
