One of the concerns with internationally produced spirulina is the chance of unwanted bacteria or radiation contaminating the spirulina. Zhou’s non-GMO spirulina powder solves this issue by producing their spirulina in a remote location in California, in a closed-loop filtration system made to reduce any chance of contamination. Made with the blue-green variety of this powerful algae, this spirulina powder is vegetarian-friendly, as well as gluten and allergen free, meaning you can add it to your diet with confidence. Boasting the same nutritional content as seven servings of fruits and vegetables, this powder offers the health benefits you crave without any of the hassle.
Countless customers boast about the energy-boosting effects of this spirulina powder, though they do note the taste is a bit strong at first and recommend cutting it with natural ingredients like bananas and peanut butter in a smoothie. They also note this powder is much darker than some of the others on the market, which may seem disconcerting at first, but the health benefits are well worth both the taste and appearance of this immune-boosting beverage. The one downside to this product is it does only once in 6-ounce containers, but that is made up for by the quality of the spirulina powder itself. After all, some of the best things in life come in small packages, including Non-GMO Spirulina Powder from Zhou.
- PREMIUM SPIRULINA. Sourced from a remote spirulina farm in Southeastern California, clean air and mineral-rich water yield premium spirulina. A closed-loop water and nutrient recycling process is used during production to care for you and the environment.

- BETTER THAN CHLORELLA. This blue green algae contains the highest concentration of protein of any plant, herb, or animal on a gram per gram basis. It contains more essential amino acids, iron, protein, B vitamins, and vitamins C, D, and E than chlorella.
- POTENTIAL HEALTH BENEFITS. Just 2 servings a day of our Spirulina Powder equals as much as 7+ servings of fruits and vegetables in terms of antioxidant content. This powerhouse superfood helps support overall wellness and bodily function.
- WHAT SETS US APART? At Zhou, we use only the highest-quality ingredients in an FDA certified facility following GMP (good manufacturing practices). Plus, we test everything at our lab in Utah, so you can be confident that you’re fueling your body with the very best.

- SUPER VALUE: Our 100% Pure Organic Spirulina comes in a 2.2 pound (1 KG) container. Ounce for ounce, we offer the least expensive Organic Spirulina Powder available on Amazon. With a standard serving size of one level teaspoon, each container provides 303 servings.

- MESS-FREE CONTAINER: Our Organic Spirulina Powder is packaged in an air-tight, mess-free container. The container is easy to open and close, and the powder can be cleanly accessed through the wide top opening.

Spirulina Supplement Purchase Guide
While spirulina has been proven using evidence-based methods to help with a wide range of maladies and nutritional deficits, it is always a good idea to talk to your doctor before beginning a new supplement. With all that aside, it can be hard to know what you’re looking for when shopping for spirulina powder, which is why we’ve pulled together a helpful guide below.
Organic vs. Non-Organic
While in most cases organic is always the way to go, as it guarantees that the product has been grown with both consumer and environment health in mind, as well as with limited pesticides and fertilizers, in the case of spirulina many times non-organic blends offer similar, if not better benefits when compared with their organic counterparts.
This all depends on the process used to grow the spirulina. Certain fertilizers used by organic producers are high in heavy metals, which can contaminate the end product, and if not grown correctly spirulina can contain bad bacteria, which is why it’s important to do your research to find out the individual practices of your spirulina powder provider.
Flavor vs. Unflavored
Many people find that spirulina has a fishy flavor, similar to seaweed. While this isn’t an issue for many consumers, some find the taste off putting and have compared it to smelling like an aquarium. It’s best to look for spirulina powders that are pure as far as production goes, but added flavors do not necessarily decrease the nutritional benefits of spirulina. Just make sure to keep in mind that some flavor additives increase total calories per serving, and can add unwanted carbs in the form of sugars.
Spirulina Powder Serving Size
The recommended daily amount of spirulina is between 1 to 3 grams. However, it’s best to follow the instructions provided by the product manufacturer, as well as your doctor, before beginning this product.
Questions About Spirulina Powder
How Long Has Spirulina Been Used as a Supplement?
Some records list the Aztecs and other Mesoamericans as the first people to take advantage of the health benefits provided by spirulina, first documented around the 16th century. They called it “Tecuitlatl,” and used it to make cakes for consumption. It moved back into the main market in the 1970s, and gained popularity for a time as a food that could potentially be grown in space.
Is Spirulina Dangerous?
On its own, spirulina is not dangerous. However, it can become dangerous, much like any other food, if grown in the wrong conditions. Bacteria and other toxins can contaminate poorly grown spirulina, and put you at risk for nausea, vomiting, liver damage, and more. That is why making sure you know where you spirulina is produced is crucial to choosing any supplemental powder.
