What Is Spirulina?

What Is Spirulina?

Spirulina is known as blue-green microalgae that is processed as a dietary supplement. It contains 70% more protein than soybeans, chicken, and beef. It also has high levels of vitamins, iron, Gamma Linolenic Acid, protein, calcium, and beta-carotene.

Some people take spirulina in the form of pills while others take it in powder form by putting it in their drinks or meals.

What Is Spirulina Powder Good For?

There are numerous health benefits that spirulina brings. Spirulina powder benefits include combatting fatigue, viral infections, cancer, and high cholesterol. It is also believed to improve the immune system as well as our kidney and liver.

However, it should be noted that studies continue to research on the benefits of spirulina powder since there is only little scientific evidence to prove such claims.

What Is The Best Spirulina Powder Brand?

There is no single best spirulina powder brand in the market. It all depends on the ingredients that the brand uses and your preference for its taste and smell. But if we were to base it on Amazon’s Choice list, the first brand on the list is BN Labs.

Spirulina Powder Buying Guide

Choosing the best spirulina powder in the market can be tricky. You might just get the wrong kind if you don’t know what you’re looking for. Every brand out there will try to claim they’re the purest and organic spirulina powder. But with this guide, we’ll help you spot the ones that are safe to buy.


If you buy spirulina powder, the first thing you have to check is the ingredients. The only words you need to see are organic spirulina powder. You may also come across words such as spirulina platensis or arthrospira platensis. Other than that, there shouldn’t be any ingredients on the label.

By just reading those simple words, you can be assured that what the brand is using is purely spirulina and nothing else. If you see other ingredients on that list then it’s not 100% pure.


You might see a few certifications on the label of the spirulina powder brand you like such as Clean Certification or Raw Certification. This ensures that the spirulina processed was done in the cleanest environment possible. Some brands will also carry halal certification for those who practice this.


Spirulina will have a mild odor. It will not affect the taste but the odor will be akin to that of a fishy smell. It should be noted that this is normal. However, when you detect a strong odor, it’s best to switch to some other brands that smell milder. Sometimes, a strong odor can mean a damaged product.


Spirulina powder is usually packaged in bottles or re-sealable pouches. Both are fine, but it should be noted that some re-sealable packages don’t zip close too well. If the brand carries a bottled one, it would be best to buy this instead of the pouch.

Expiry Date

As a rule of thumb, always check on the expiry date of the products you’re about to buy. Spirulina powder expires so do read the label and see what the expiry date is before buying.

Extra Details

Spirulina is already healthy, to begin with. But it could even be healthier. For instance, if a brand doesn’t use any animal fertilizer, then spirulina would be considered vegan-friendly. You should also check whether it’s non-GMO, soy-free, and gluten-free.
