This product is made from a single ingredient; spirulina, which is a good source of vitamin A and vitamin B 12. It is also full of naturally occurring GLA (gamma linolenic acid), chlorophyll, amino acids, cell salts, fatty acid and trace elements.

The proven benefits of spirulina include:

  • Helps to protect against oxidative damage thanks to an active compound called phycocyanin, which helps to fight against free radicals [1].
  • Has been shown to lower LDL (bad) cholesterol levels and triglycerides that have been linked to an increased risk of heart disease [2].
  • May have anti-cancer properties, with research on animals showing that spirulina could reduce the occurrence of cancer and the size of any tumors that do appear [3].
  • Shown to reduce blood pressure, which is one of the main causes of heart attacks, strokes and chronic kidney disease [4].
  • Can be used to treat anemia, with research showing that this ingredient could increase the haemoglobin content of your red blood cells, with an improved immune function [5].
  • May improve muscle strength and endurance with research finding that this ingredient could increase the time it took for people to become fatigued [6].
  • Shown to outperform the popular diabetes drug Metformin at lowering blood sugar levels [7].

Potential Side Effects

Side Effects

Spirulina is generally considered safe to use, although some users do experience nausea, insomnia and headaches.

There are a few more severe side effects you should be made aware of:

  • Spirulina that has been harvested in the wild may contain heavy metals, bacteria and harmful particles known as microcystins. These could be harmful to your body [8].
  • Even though it has been shown to boost your immunity, spirulina may worsen autoimmune diseases such as lupus, multiple sclerosis and rheumatoid arthritis [9]. These are all diseases in which your immune system attacks your body.
  • It is an anticoagulant, which means that it can thin your blood and stop any cuts from clotting [10].
  • Those who have other allergies are more likely to be allergic to this particular ingredient. In some cases the reactions can be fatal [11].

If you do encounter any side effects you may wish to discontinue use. You may also want to speak to a doctor.

There is little risk of encountering any allergens as this product is not manufactured with yeast, wheat, gluten, soy, milk, egg, fish, shellfish or tree nut ingredients.

User Reviews

The user reviews for this product are quite mixed. Those that did were impressed with both the nutritional content and the price that this is being offered at.

“I like to use spirulina because of its nutritional value. I may not be a lab technician or nutritionist, but I feel great after taking my dose. Buying a 4 pound container of Now Foods spirulina is a bit too much for me so I opt for a 1lb option instead. Quite cost-effective, too!

“High quality, low price. That’s how you want it. With Now Foods, this wish came true. I’ve heard complaints about the taste, but I don’t mind it personally. There’s no hint of fishiness, but fresh mowed grass instead, which is not all that bad. Kudos!”


- Sinbadsmom

The negative comments were mostly regarding the taste and smell of the supplement.

“I'm very disappointed. The taste is awful, the smell is unpleasant, I feel like I’m owning a cattle ranch. If I wanted one, I could just go down the road where I live and find one. No, thanks!”


- L.M.L. Wilson

“I love spirulina products. I can eat pretty much anything, but this was a challenge. Why? I guess it depends on where you buy your supplements. The ones I got came from China and they don’t seem to uphold the same safety standards as the US. I have been a big fan of Now Foods but I will be more cautious when making my purchase.”

How To Take Now Organic Spirulina?

For best results you should mix 1 level teaspoon of Now Organic Spirulina with either water, fruit or a vegetable juice.

Is Now Foods Organic Spirulina Suitable For Vegans?

Yes, Now Foods powder is suitable for vegans. There are no animal-based ingredients to be found in this supplement.

Can Now Organic Spirulina Powder Be Used As A Meal Replacement?

You should not use Now Foods powder as a meal replacement.

While it contains many different vitamins and minerals, a supplement like this cannot replace a healthy meal.

Where Is Now Foods Spirulina Grown?

It is not clear where Now Foods Spirulina is grown.

According to the manufacturer it does not matter where its ingredients come from as they are rigorously checked before they are used in the various supplements that Now Foods manufacture.

Should You Buy Now Organic Spirulina Powder?

There are certainly some perks to buying this supplement from Now Foods. For instance, it can increase the number of certain nutrients, and will certainly improve your overall health. It is also quite affordable too.

Unfortunately, there are a few issues that prevent us from recommending it to you.

A major issue is the taste, which will take some getting used to, although it might be okay if you add to any smoothies that you make.

There is also very little protein in each serving, and virtually no fiber. This means it is unsuitable for use as a meal substitute.

Our suggestion would be to look at Organifi Green Juice.

It is a much better option, with more vitamins and minerals as well as trace elements available. It may be a bit costly compared to Now Foods, but it tastes delicious and there’s a money-back guarantee available, which is always a tell-tale sign that the company has faith in both its supplements and users.
