Choosing the Best Spirulina Supplement

Choosing the Best Spirulina Supplement

Over the last decade we have seen a huge shift within the supplement industry, resulting in the increased investment into all natural and organic health products, thus shifting away from our more traditional pharmaceutical type compounds.

Many of these natural remedies have been shown to boost health in a very big way, while also providing the body with a variety of key essential nutrients that the human body needs to function at a high level every single day.

One of these natural health boosters that has been receiving a lot of positive attention within the health industry of late is spirulina – an extremely nutrient dense product that is being touted as the next big superfood.

But what is it? And more importantly, does it really work?

What Is Spirulina?

Spirulina is actually one of the oldest life forms found on earth – it is a specific type of blue-green algae that has been consumed for centuries in ancient African and Aztec culture, where it was suggested to promote health and longevity.

Despite being consumed by ancient civilisations for the better part of a millennia, it has only recently regained its popularity in western culture due to the suggestion that it may have the capacity to be grown in space. Thus, it may offer astronauts with a highly nutritious food that can be obtained easily and effectively.

And when I say highly nutritious, it’s important to note that I mean highly nutritious.

In fact, gram for gram, spirulina might genuinely be the most nutritious food on the planet. Within this, it is full to the brim with a multitude of essential vitamins and minerals, provides a solid portion of protein, and is overflowing with potent antioxidants – and it is through the combination of these factors is where spirulina derives its health benefits.

What Are the Health Benefits of Spirulina?

Considering the extremely potent health properties of spirulina, it has garnered a lot of attention within the health industry of late. With this has come an abundance of research looking into both its benefits and its effectiveness. Considering this, we wanted to take an objective look at the research to determine where its best use lies.

Does Spirulina Help Reduce Inflammation?

Every single day the body is exposed to various types of stress. This can come from chemicals in our food and water, lifestyle and work-related stress, and even from environmental mutagens, such as heavy metals and UV rays.

This stress leads to an inflammatory response, which when prolonged, can cause cell damage and an associated decline in health and function. Interestingly, many of the antioxidants found within spirulina have been shown to reduce inflammation and cause subsequent increases in health and function as a result [1].

Can Spirulina Lower Blood Cholesterol and Blood Pressure?

The regular consumption of spirulina has been shown to cause a reduction in the levels of LDL (or bad) cholesterol found within the blood, while also lowering the levels of blood triglycerides significantly. This has come with associated reductions in blood pressure and improvements in cardiovascular health [2].

As both of these are considered key risk factors for cardiovascular disease, diabetes, and metabolic syndrome, spirulina is also highly likely to have a preventative effect on these diseases.

Does Spirulina Help Protect Against Cancer?

As previously mentioned, spirulina contains a variety of antioxidant compounds, many of which interact with the body at a cellular level to enhance health. Amazingly, there is an abundance of recent research to suggest that these compounds may also exhibit anti-cancer properties.

The supplementation of spirulina in animal studies has been shown to reduce cancer occurrence and cancer size [3], while there is some human evidence to suggest that it may also stop the spread of oral cancers when taken regularly [4].

While the research is only in its early stages, it does suggest that spirulina may provide a good addition to traditional cancer treatments.

Does Spirulina Boost Immune System Function?

And finally, many of the essential nutrients found within spirulina play important roles within the maintenance of normal immune system function. With this in mind, the daily consumption of spirulina can ensure that all of these nutrients are readily available for use within the human body.

If you combine this with the reduction in inflammation that it causes, we see huge improvements in immune system health and an associated reduction in risk of illness and disease [5].
