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.

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.
