The Benefits and Side Effects of Spirulina

Blue-green algae, chlorella, and spirulina are all advertised as being beneficial, but they could be harmful because they are often contaminated with algal toxins.

Thanks for watching. I hope you’ll join in the evidence-based nutrition revolution!

Been using Healthy Origins Spirulina daily for about 18 years. The ONLY colds i get is when i forget to order more and run out. Also helps considerably for inflammation, i can tell when i do t take it. Theres always been the contamination thing but dont buy it from a back alley.

I used to take spirulina and I gave it to my dog. But soon quit because I just didn't feel right about it somehow. After hearing you on the matter I'm pretty happy I went with my sixth sense.

Luckily i've always been too cheap to buy any Spirulina in the first place, so not affected by this. Thank goodness!

Interestingly there's a new product I noticed at Walmart by Kencko. They have an interesting product line that has promise it appears but they use spirulina and some of them. I reported the potential problems to them a few weeks ago. We've been going back and forth since and they said they do third party testing. I shared with them over the weekend your old video on this topic and how they need to test every batch. I wish you would have said that in this video too. I had just shared your old video with them so I shared this one with them again today!

Been using both chlorella and spirulina nearly every day for more than 40 years. Far less energy when I don't use it. Just my personal experience, I guess. Your kilometers may vary.

You didn’t mention the positive effects on sinus congestion. I have lived for 20 years with a chronic sinus infection and nothing helped till I started using spirulina. I have been using it for 3 mos and I haven’t felt better. Sad to hear this. 😢

I've always used wheat grass powder, so never felt the need for spirulina.

I never heard of Spirulina before ! Great video ⭐

Years ago i tried a chlorella supplement & all my joints seemed to grow very angry, where i was just fine before starting it. I thought it might be some coinkidink, so i stopped taking it for a little while (btw: as soon as i stopped, my joints returned to normal). Once i re-introduced it, the same thing happened! Binned that bottle. Maybe contaminants?

Edit: interestingly, spirulina in smoothies was yummy & just fine for me...no angry joints or other adverse reactions.

It does give you energy however I notice that it makes me cold in the winter. it is tropical food. Chlorella however is natural to colder climates.

Thank you so much for sharing! So important.

You mention that many algae products are contaminated with various things, what does this mean for algae-based omega 3 supplements?

[kristijangalekovic]

I'm taking it as the iron suplement. What to take instead?

[kiwilander]

So, no control group tests for location? One can't assume the same toxins exist in different countries

Spirulina has been making me feel on top of the world! I only take the Pure ones, not the contaminated one!

[Phoenixrises]

Gutted as just bought a full years worth of these and chlorella, before your other video came out!!!

Invested because of how good they are both supposed to be, but now, not taking the risk!!!

[emergentform]

Wow there's an eye-opener. Hooray Dr. Greger!

[KevinLuna]

Have you tested Purium's Spirulina?
