The 10 Best Spirulina Supplements

Spirulina, a type of blue algae, is considered a superfood by many people. It belongs to the family of highly photosynthetic cyanobacteria. Spirulina is much sought-after for its unique nutritional content of proteins, vitamins, minerals, chlorophyll and other phytonutrients that can benefit the human body immensely.

Spirulina is naturally found near alkaline lakes especially close to volcanoes that are rich in minerals. Nowadays, it is specifically grown in countries such as Japan, Taiwan, China, India, Hawaii, and Africa.

Why Use Spirulina Supplements?

Spirulina has a rich protein content of 50 – 70 percent and contains a total of 19 amino acids. Besides, it is a great source of Vitamin A, B vitamins and has an exceptionally high content of iron and other minerals which would be difficult to obtain through our daily diet. So the most ideal way to get the best benefits of spirulina is through good supplements.

Just one tablespoon of  spirulina powder has 4 grams of protein, 11 % of RDA (Recommended Dietary Allowance) of thiamine, 15% of riboflavin RDA, and 15% of niacin RDA. This also offers you 21% of your RDA for copper and 11% of RDA for iron. With just 20 calories, this also offers you 1.7 grams of digestible carbs.

Spirulina supplements are available as capsules, tablets and powder forms. The powder forms have an ‘earthy’ taste that can be masked by mixing in water, juices, smoothies or even food preparations to make it nutrient-rich and easy to consume. Using quality brands with relevant certifications will ensure that the spirulina you consume is safe and free from contaminants and allergens.

There are many top-ranking spirulina supplements available online. We have given you a selection of the best 10 spirulina supplements that may provide the best benefits and value for money. Explore each supplement and select the one that is most suitable for you.

Things to Consider When Buying a Spirulina Supplement 

Spirulina supplements are available in the form of capsules, tablets, and powders. Many brands manufacture and distribute spirulina supplements.

Listed below are some guidelines that you can use to select a product that comes with the right quality and is free of contaminants to be of great benefit to your health.

  • The spirulina powder in the product should be dry and loose. If it is sticky or moist to the touch then it may not be of the right quality
  • Pure spirulina has a deep, dark green color. So if the powder is of a lighter shade or has traces or white, chances are that its not 100% pure spirulina
  • Fresh spirulina is odorless and dry spirulina has a light smell-of-ocean. It should not have a fishy, highly bitter or salty taste.
  • The product label should specify the nutritional content. 
  • If the price is dead cheap or comes at a massive discount, just don’t go for it as you may be compromising your health.
  • If the product does not specify the location from where spirulina is sourced, it may be of cheap or wild quality that may contain contaminants
  • Research the company’s website for information on certifications, methods, processes used as well as their customer service policy to ensure the right quality and after-support
  • Organic does not always mean pure. Location, method of growing, harvesting and quality processing is what matters
  • It’s always a great idea to check for third-party certifications for any supplement you buy as they guarantee purity and quality.

The Final Note

We do not always get the right nutrition that our body requires to maintain good health and proper functioning of our body. To bridge the nutritional gaps in our diet, adding spirulina supplements to our daily diet is a smart option. Spirulina is considered as a superfood owing to its nutritional content.

But it is of vital importance to research the various supplements available, to select one that can benefit you with essential nutrients and at the same time is free from contaminants, artificial ingredients, chemicals and allergens for assuring safety in consumption.
