Where is spirulina grown?

 Wild spirulina grows in the alkaline lakes of Mexico and on the African continent, although it is commercially grown and harvested all over the world now. Spirulina grows in warm, fresh water-bodies where there is abundant sunlight. It can also be grown in an artificial setting.

Is spirlina good for you?

 Spirulina is one of nature’s near-perfect foods. Many studies have shown that spirulina is a very healthy nutritional supplement. It helps your immune system, provides a boost of energy almost immediately, and is a natural detoxifier as it helps cleanse your body of toxins and impurities.

What are the health benefits of spirulina?

Spirulina is a healthy super food. It’s a good source of protein, vitamins, minerals, and essential fatty acids, especially rich in beta-carotene and vitamin K. It’s an immune system booster, gives you more energy, and it’s a natural detoxifier. Check out our top 10 health benefits of spirulina to learn more.

What kind of spirulina should I buy?

We primarily recommend buying spirulina in powder form because you can mix it with other foods to cover up the less-than-wonderful taste. But you can also buy it in tablet form if you’d rather take a couple tablets every day. Both are great options.

Should I only buy organic spirulina?

It is always a good idea to eat natural, organic food whenever possible. However, don’t be scared of inorganic spirulina without exploring the details. In fresh water ponds, spirulina is naturally grown among inorganic fertilizer from nature with phosphorus, nitrogen, and natrium. Take the time to research the brand of spirulina you buy or pick from our favorite spirulina brands.

Is spirulina safe?

The short answer is yes. The longer answer is that studies on humans and animals have shown no toxic side effects directly due to spirulina. There have been no negative side-effects found in studies on animals. Spirulina may not be safe if it is contaminated with other toxic blue-green algae. Because it is a dietary supplement in the US, there is active regulation of spirulina, but it is considered safe, as long as it’s not contaminated with other toxins. Each brand of spirulina will give you details on the safety of its products, but there is generally no need for concern!

Can pregnant women consume spirulina?

Yes! Many women even increase dosage during pregnancy.

Disclaimer: of course you should talk to your doctor if you have specific questions or concerns.

Should kids consume spirulina?

Yes, again! Just as pregnant women can eat spirulina, so can children.

Is spirulina vegan?

 Yes! Spirulina powders and tablets are a vegetarian/vegan superfood! Check the label if you are concerned that non-vegan ingredients are being added.

Where can I buy spirulina?

You can buy spirulina powder and tablets at health food stores and some grocery stores. You also research and buy spirulina on Amazon (our preferred way because of course who doesn’t love 2-day shipping).
