Is Spirulina Good for Cholesterol?


Is Spirulina Good for Cholesterol?


Does spirulina help in lowering cholesterol?

Spirulina supplementation is a good way to maintain cardiovascular health and avoid serious cardiovascular diseases.

Is spirulina good for high triglycerides? Does spirulina lower LDL?

Spirulina helps lower LDL cholesterol (bad cholesterol) levels and triglyceride levels in the body. In 2014, a trial was conducted, which showed spirulina’s potential to help lower cholesterol levels.

The said spirulina cholesterol study involved 52 participants aged 37 to 61. Their full lipid profiles were measured before undergoing the trial and after the study period. The participants were asked to consume a gram of spirulina daily for 12 weeks or 3 months.

But how much does spirulina lower cholesterol? According to the study, spirulina supplementation has helped reduce triglyceride levels by 16.3%. It also helped in lowering LDL cholesterol by 10.1%.

Apart from helping lower LDL cholesterol, studies have found that spirulina helps increase HDL cholesterol levels.


Other Cardiovascular Benefits of Spirulina


The cardiovascular benefits of spirulina don’t end when it lowers total cholesterol and LDL cholesterol levels. Here are some positive effects spirulina supplementation may have on your cardiovascular system.


1. Spirulina Helps Minimize Lipid Peroxidation


What effects does spirulina have on cholesterol?

LDL cholesterol is a fatty structure, and as it is such, it is prone to causing oxidative damage in the body. If this damage happens to blood lipids like bad cholesterol, it can cause multiple diseases and health issues. It’s a scenario called lipid peroxidation. This damage is also known as a stage connected to developing heart disease.

Studies have found that spirulina, besides its cholesterol-lowering effect, can help minimize lipid peroxidation. This is all thanks to the antioxidant content spirulina has. In fact, spirulina may even help reduce fatty structure damage incurred from exercise, along with reducing inflammation and the damage your muscles may suffer.


2. Spirulina Helps Lower Blood Pressure


Yes, apart from the fact that spirulina lowers cholesterol, another one of the many positive effects of spirulina is lowering blood pressure.

Being hypertensive or having high blood pressure is one of many risk factors for multiple health issues, especially cardiovascular disease and kidney disease.

Luckily, spirulina supplements may help with this. One research review analyzed and compared five different human clinical trials and studies looking into this. Most of the said studies observed the effects of spirulina supplementation when taken in daily doses of 1 to 8 grams.

In the said review, the researchers concluded that spirulina consumption significantly improved systolic blood pressure and diastolic blood pressure.

But how does spirulina do this?

One spirulina property that aids in lowering blood pressure is that it also helps up the production of nitric oxide in the body. Nitric acid helps reduce arterial stiffness, contributing to reducing blood pressure.


3. Spirulina Helps Reduce Blood Glucose Levels


Uncontrolled high blood sugar levels due to diabetes, insulin resistance, and a high fructose diet may negatively affect the cardiovascular system. Such conditions may contribute to damaging the blood vessels throughout the circulatory system and the nerves that control your heart.

Luckily, microalgae spirulina supplements can help lower blood sugar levels.

Several studies on this superfood have observed that it can contribute to managing blood glucose levels. According to a 2018 review, spirulina may help lower fasting blood glucose levels significantly.

Meanwhile, another study observed 25 participants with type 2 diabetes mellitus. The study found that spirulina supplementation helped improve their symptoms.


Other Health Benefits of Spirulina


Apart from supporting and maintaining your cardiovascular system, there are still many health benefits this superfood can provide. Here are some of them:

  • Spirulina has anti-inflammatory properties. Studies have found that taking a spirulina supplement helps reduce our bodies’ inflammatory response, which also works great in easing symptoms of allergic rhinitis.
  • Spirulina helps boost the immune system as it can help boost white blood cell and antibody production.
  • Spirulina helps reduce muscle fatigue after exercise and improves overall fitness. It also helps reduce body weight.
  • Spirulina has potent antioxidant properties that can help fight the damage from oxidative stress.
  • Spirulina is rich in iron, which can help those with iron deficiency anemia.
