Spirulina is a superfood that you can effortlessly add to smoothies, juices, or even salads and soups for a nutrient-packed boost. But despite how many spirulina powders are on store shelves, they aren’t all created equal. “When looking for spirulina, and this goes for all powders/supplements, I try to look for brands that have minimal ingredients, or only one ingredient,” registered dietitian and functional medicine nutritionist Nathalie Rhone, MS, RDN, CDN, and founder of Nutrition By Nathalie, tells Bustle. The best spirulina powders contain no fillers, are transparent about where they are sourced, and are non-irradiated, which means they haven’t been exposed to radiation.

There are two main types of spirulina: green and blue. Both contain protein, B vitamins, and phycocyanin, an anti-inflammatory phytochemical. But, whereas green spirulina is a whole cell algae that has a fishy scent and taste, blue spirulina is an extract with a more neutral smell and taste that isn’t quite as nutrient-dense. Regardless of which you prefer, Rhone says it’s important that your spirulina powder has a deep matte color. “If your spirulina has a shiny appearance it was likely treated with a coating,” Rhone says. Reading labels and avoiding fillers is also important. “Harmful ingredients and fillers look something like high fructose corn syrup; oils like corn, cottonseed, canola; artificial food coloring, flavors, sweeteners; natural flavors; sodium nitrate/nitrite; BHA; MSG; and caramel coloring.”

Unless it is grown in safe conditions, some spirulina can become contaminated with toxic metals and harmful bacteria. In addition to keeping ingredients clean and simple, a quality spirulina brand is clear about where it sources its algae and is free from contamination from pesticides, herbicides, and radiation — look for a spirulina that is labeled “non-irradiated” to be sure.

“Another thing to keep in mind is that like other dietary supplements sold in the U.S., there is no active regulation of spirulina,” Rhone says. “If you aren’t sure about a product reach out to a registered dietitian who can help you find a product that’s properly manufactured, contains the listed ingredients, and does not contain harmful levels of contaminants.”

Below you’ll find five of the best spirulina powder options for your budget and taste buds — just remember to always check with your doctor before starting a new supplement.

A helpful review: “What's not to love about Doublewood? Clean, quality, supplements at a reasonable price. This spirulina is at least as good as the blue-green I've used before but with a dare I say pleasant flavor? Kind of a nutty flavor? Big energy and clarity boost. Good stuff!”

Helpful Review: “I LOVE this product! I had to subscribe monthly. I used to love sour apple candy when I was younger and now this flavor is in a healthy supplement form?!?! LOVE this! You gotta try it if you already take Super Greens supplements in other brands, which I have. I'm not a fan of chocolate greens and the normal greens are hard to take down, and this GREEN APPLE flavor is the best by far! So glad I found this brand!!!!”
