What is Spirulina Powder?

Spirulina powder is from a type of blue-green microalgae (spirulina) that is one of the oldest forms of life on the planet and is often considered a superfood. Spirulina grows abundantly in tropical, fresh water, alkaline lakes often found near volcanoes. It was used by the Aztecs for food, and NASA even investigated using it as a food source for astronauts due to its extremely high nutrient profile.

Spirulina Powder Benefits

Spirulina powder is one of the most nutrient-dense foods on the planet and is loaded with vitamins and minerals such as beta-carotene, vitamin B12, iron, magnesium, and more. It contains 19 of the 22 amino acids the body needs and is nearly 70% protein by weight — more than beef. Spirulina powder is rich in antioxidants and has natural anti-inflammatory properties. It also supports cardiovascular function and is heart healthy.

The best spirulina powder feature is its versatility. It can be mixed taken with water, mixed into your favorite beverage, or backed or cooked into your favorite foods.

I recommend this product
Affordable and quality product

I feed spirulina to my horse at a rate of 4TBS a day, and had a hard time finding a large volume at an affordable price. BulkSupplements solved both those problems. It's good quality and doesn't have a super fishy odor like some other spirulina options.

I use this for my older dog and she loves it

Closure mechanism lame. All products.

Products fine. Closure mechanism lacking. Makes storing problematic and requires extra effort. Competitive products are able to use workable closure. Is your margin is so tight you can't that an upgraded closure mechanism (perhaps with tab piece? - above and beyond).

Decent quality product, good service

Shipping was fast, quality is okay, yet it would be useful to mention the origin, since spirulina grows in many different places in the world, and quality varies greatly depending on origin.

Purchased for a friend

I have a friend who would come over and fix himself a smoothie. I decided to buy him a bag for home. He enjoys it.

Great product for value and quality.

This product is amazing! I have included 2-3 tsp into my protein shake each morning. I like how it blends without any harsh taste and gives me additional nutrients.
