1.    Garlic

According to Livestrong, garlic may improve blood flow, and research backs this up. An older study found that healthy volunteers who took garlic supplements for a week exhibited improved blood flow to the calf muscles. It is thought that whole garlic can produce the same effects.

2.    Oranges

We all know that oranges are chock-full of vitamin C. But did you know that vitamin C can be good for blood circulation? Experts say that cholesterol can slow down and even block blood flow. However, the vitamin C found in oranges can help to prevent this issue.

According to the George Mateljan Foundation, vitamin C is an antioxidant, which can destroy free radicals. This is important because once free radicals are oxidized, cholesterol can bond with the walls of your arteries. Consequently, plaque builds up, which can slow or block the flow of your blood. In neutralizing free radicals, vitamin C can help to prevent this process, which may improve circulation.

3.    Olive Oil

It’s no secret that olive oil and heart health are said to be a team. But just why is this?

According to the Mayo Clinic, olive oil’s main fat is a heart-healthy type of fat called monounsaturated fatty acids (MUFAs). These (along with polyunsaturated fats) are the fats that you want to eat on a regular basis.

Generally, MUFAs can help to reduce the risk of heart disease because they may lower cholesterol levels and can regulate blood clotting. These factors combined ultimately may improve blood flow.
