which all vitamins and minerals does a garlic contain
Additionally, garlic is an excellent source of manganese and vitamin B6. It is also a very good source of vitamin C and copper. In addition, garlic is a good source of selenium, phosphorus, vitamin B1, and calcium. The cardioprotective benefits of garlic may partly rest on the production of hydrogen sulfide (H2S) gas. 2  Our red blood cells can take sulfur-containing molecules in garlic (called polysulfides) and use them to produce H2S. 3  This H2S in turn can help our blood vessels expand and keep our blood pressure in check.
