Wondering about the KOS Spirulina Powder?? Then you have come to the right place! I’m a vegan, plant-based registered dietitian and I love to share with you vegan reviews of food and other related products…like this KOS Spirulina!

First of all, let’s talk about it..what is spirulina powder?? Spirulina is a type of blue-green algae that is consumed as a dietary supplement that has many potential benefits. Some of those benefits of spirulina include:

  • Spirulina can potentially lower triglyceride levels
  • Spirulina may reduce allergy syptoms
  • The blue-green algae may help cholesterol levels
  • Spirulina may help with blood sugar levels
  • Spirulina may help increase overall athletic endurance and muscle strength

Taste Experience

So how does the KOS Spirulina Powder taste?! Honestly, it tastes pretty earthy and grass like on it’s own and I wouldn’t consume it on it’s own. Most people add spirulina to smoothies – which is exactly what I do too. Some others add it into homemade granola or granola bars or energy bites, but honestly I think the taste is a bit too strong for all of that.

Spirulina does taste a bit ocean-y as it is a blue green algae, but it’s not near as strong of a taste as seaweed or other ocean plants. So if you are a vegan that doesn’t like anything even remotely fishy tasting (like me), then you will be just fine with the KOS spirulina powder.

In many protein powder smoothies, if you add too much KOS Spirulina, it will get powdery and chalky tasting but I think by using 1/2 to 1 scoop of the measured scoop provided, it prevents that. I’ve tried adding two scoops when making a double batch smoothie and it was too over powering – so stick to just one.

Spirulina is an acquired taste for many, similar to wheat grass but if you like earthy, plant like tastes, you’ll be more apt to like it. This KOS spirulina is also the finest high quality I’ve come across in the spirulina product realm – most are gritty and have a larger texture.


The KOS Spirulina doesn’t have a nutrition label as it’s considered a supplement but it’s a natural source of many B vitamins, Vitamin A, and even protein! Yep, in one tablespoon (that’s nothing!) there is 4 grams of protein, and 11% of both iron and thiamine. There’s 15% of riboflavin and 4% niacin (both B vitamins) in that same tablespoon serving.  Spirulina is naturally nutrient dense and the KOS Spirulina is a great nutrition boost to your day!

One tablespoon of KOS Spirulina is loaded with nutrients!
