What to know before you buy a spirulina supplement

What is spirulina?

Spirulina is a cyanobacterium that’s cultivated worldwide for human and animal consumption. Most commercially-available spirulina is grown in California, Mexico and parts of Africa. Spirulina has a long history of human consumption that dates back to the Aztecs. Spirulina is a popular ingredient in healthy food and shakes thanks to its nutritional content.

Spirulina health benefits

According to the National Institutes of Health, spirulina has hypoglycemic, antihypertensive and hypolipidemic properties, meaning it may naturally stimulate insulin production, reduce blood pressure and help with cholesterol. Additionally, spirulina has a high protein content, making it an ideal protein source for many vegans. Spirulina is generally nutritious, as it’s high in minerals, essential fatty acids and vitamins such as vitamin B12. Users of spirulina often feel the supplement gives them an energy boost and healthier skin.

Types of spirulina supplements

The two most popular types of spirulina supplements are spirulina tablets and spirulina powder. Spirulina powder is the preferred form of spirulina for people that want to add it to their drinks or food. Spirulina tablets are the easiest way to add spirulina to your diet, although they typically don’t have as much protein in a single serving. Most spirulina tablets and powders are vegan-friendly unless they’re made with gelatin.

What to look for in a quality spirulina supplement

No added ingredients

Not all added ingredients are harmful, but supplements with fewer ingredients tend to have a higher spirulina content. Additionally, avoiding added ingredients will help ensure that your supplement is vegan-friendly and generally healthier. 

Dark-green color

When buying spirulina, it’s a good idea to get a dark green supplement. In some cases, spirulina is actually blue. Much like green spirulina, if you opt for the blue variety, you’ll want to get a dark blue supplement.

Easy to consume

When buying spirulina, it’s ideal that you buy a brand that others find easy to digest. Some spirulina may not taste great, so you can avoid the unpleasant flavor by using spirulina tablets. Still, many spirulina powders taste pleasant, especially when blended in a smoothie. If you decide to buy spirulina tablets instead of powder, you’ll want to get tablets that are easy to swallow.

In some cases, you may find spirulina challenging to consume, not because of its taste but because of its smell. Still, many spirulina supplements have a neutral smell that users don’t mind.

How much you can expect to spend on spirulina supplements

Bottles of 500 or more spirulina tablets tend to cost around $15-$25. Powdered spirulina costs about $20-$30 for a pound of powder.
