How We Ranked These Products

When looking at Spirulina supplements, there are a few factors that should be considered to determine which of the options on the market might be the right choice for you. While analyzing different supplements that contain Spirulina as the main active ingredient, we used specific criteria to filter through these products. In the end, we provided you with five of the best ones to consider. Below, you will find the criteria that we used to filter out the products that may not be worth the money.

Spirulina Dosage

The dosage of the supplement, based on each serving, is a factor that will tell you how effective the product may be. When the dosage is too low, you will not obtain enough of the nutrients, as well as natural chemicals, to experience the benefits behind the Spirulina plant. When the dose of Spirulina is too strong, however, there are some drawbacks that could be experienced. People with an existing autoimmune condition, for example, may find that symptoms become worse, as NK cells in the immune system will become stronger with the use of a Spirulina supplement.

We generally aimed to include Spirulina products that contained a dose per serving ranging from 400mg up to about three grams.

Laboratory Testing And Product Certifications

When it comes to Spirulina, it is critical to understand that these plants are often polluted by microcystins, bacteria, heavy metals, and other particles that can be harmful to the human body. For this reason, laboratory testing and product certifications were two other parameters that we focused on when looking at the supplements that are available. Certifications should be provided that proves the Spirulina is organically grown and that tests were conducted to determine if any type of contaminants are present in the supplement. This way, you can be assured that the supplement you might start taking will not expose you to such toxins.

Product Pricing

The price paid for a Spirulina supplement is also something that we took into account. There is no reason to pay a premium price for a basic supplement, but some of these products do come with more certifications and higher doses – in these cases, it might be worth paying a little more to ensure you receive a purer and safer product.

We considered the price per pill, as well as per serving. We also took into account the number of servings that are contained in a bottle of Spirulina supplements and compared the prices of these products based on the data collected.

Wrapping Up

Spirulina is a plant that is rich in antioxidants and may provide several benefits to the human body. The plant is offered in a variety of forms as a supplement, but finding one that suits your needs can be a challenge. We shared our findings of the top supplements with Spirulina in this post, which concluded after a lot of research.
