How Spirulina Promotes Heart Health

Several research studies show that spirulina can lower one’s LDL (bad cholesterol levels) and improve heart health, which is important because if a person has high cholesterol it can lead to a higher chance of heart disease. This is because high cholesterol blocks off the arteries and causes the heart to pump harder (1).

In one study, patients found a 33.5% decrease in total plasma cholesterol after consuming 4 grams of spirulina every day for three months (2). A decrease in total plasma cholesterol means there is a decrease in LDL.

Spirulina may also help lower blood pressure. There have been numerous studies done to prove this as well. In one clinical study published in a 2016 Pub med journal they concluded that consuming spirulina lowers the concentration of fats in the blood and also reduces systolic and diastolic blood pressure” (3).
