Spirulina has numerous positive effects on exercise performance, cholesterol and glucose blood levels, and seasonal allergies. Spirulina is an all-natural food. Spirulina has a high protein and vitamin content, which makes it an excellent dietary supplement for people on vegetarian or vegan diets. Research suggests that spirulina has antioxidant and inflammation-fighting properties, as well as the ability to help regulate the immune system. By inhibiting NADPH oxidase, spirulina provides potent anti-oxidative and anti-inflammatory effects.

The neurological effects of spirulina need more human evidence. Based on animal evidence, spirulina appears to be a promising anti-oxidant and supplement for metabolic issues. Make sure you only take supplements that work. The nervous system and brain benefits of Spirulina include prevention of memory loss associated with age, fighting oxidative stress symptoms, promoting mental clarity and alertness, relieving depression and anxiety and promoting a balanced mood. Side effects of Spirulina are rare and usually occur when an underlying condition is present.

For both chlorella and spirulina, some of the most common side effects you hear about are diarrhea/constipation, flatulence, green discoloration of the stools, stomach cramping, and nausea. These are even more likely with a higher dosage or when you first include them in your diet. While it’s rare for spirulina to be toxic to humans, a June 2015 study in the Harmful Algae Journal found that spirulina can contain arsenic species and cyanotoxins like cylindrospermopsin and anatoxin-a. This study found that spirulina side effects included fatigue, dermatitis, nausea, dizziness and headache due to the presence of these toxins.

If you hate the groggy feeling that comes after taking Benadryl or other antihistamines, spirulina also can help you deal with your allergies without any major side effects. One recent study found that small doses of spirulina taken on a daily basis helped reduced the frequency of rhinitis amongst people who suffer from this type of allergy. Side effects and potential dangers of spirulina increase when products are contaminated. Contaminated spirulina can cause liver damage, stomach pain, nausea, vomiting, weakness, thirst, rapid heartbeat, shock and even death.

Pregnant and breastfeeding women should be especially cautious. Spirulina is a type of blue-green algae that’s highly nutrient-dense. This supplement is high in protein, B vitamins, magnesium, and beta-carotene.

It’s also a vegan-friendly source of omega-3 fatty acids and the essential amino acids that make proteins. Spirulina, being a natural source of antioxidants, is ideal for such people to recover from muscle fatigue and improve the overall strength and endurance of the body. 7. Controls Blood Sugar.

A study on rats suggests that phycocyanin from Spirulina helps reduce blood sugar levels in animals.

  • hi Peggy…I have not yet taken spirulina but heard that “Pacifica Spirulina ” by the same company is really the only Hawaiian one? is that true? is there a difference from the one you recommend? thanks a bunch! the outside labels are the same except one says Pacifica…

  • Looking at these 4 S&C tabs bulking out my ONNIT Total Primate Care pack, listening to this explanation. Thinking…. sceptical hippo. Seems like a mouthful of any given salad could replace these things.

  • Thanks for this video, why is another Dr on you tube saying it’s a dangerous neuro toxin? Bit confused and worried as I’ve been taking it..

  • I have taken Spirulina since I was 17, now 58. I started taking it in Martial Arts, as it was supposed to improve stamina. I have Crohn’s and had a resection, removal of 18 in. of the small intestine when I was 14. I do not take Rx’s of any kind. For whatever reason, I quit taking all supplements and started having more and severe Crohn’s attacks. I had not smoked pot in years when a Doctor of internal medicine recommended I do so. Now that I live in Nevada I smoke Cannabis, albeit not like when I was a kid and not for the high. I have also restarted Spirulina. I have not had a single Crohn’s attack in months. My stools are actually formed. Not sure if it is the Spirulina, Cannabis, or a combination of the two. It worked for me when Doctors had me on experimental drugs back in the ’70s that DID NOT. My parents had me at the Mayo and John Hopkins, Mayo did my surgery. I know Big Pharma would not make the money but I would like to see real research, as to why this works for me.

  • this video sucks…..bad info people…I can’t believe how many of you think that this is good information…I guess you all believe what your doc tells you…

  • Thank you so much for your video! I am usually anemic but also tend to have low blood pressure. I heard of spirulina decreasing blood pressure, would it still be beneficial to someone usually has low blood pressure? Thank you

  • he will be supporting natural remedies and not drugs when sales for natural remedies become equal or greater than what drug company’s make. sad this Dr will have to switch and start chasing the other Big Farma

  • Did he really just say that?!?!? ������ Like, for real??? ��‍♀️ I am shocked, yet I am not, because BIG PHARMA doesn’t make $$$$$ when people don’t purchase THEIR products/DRUGS, which I am certain costs, by far, MORE than buying a $26 bag of organic spirilina!!! You will be smarter for eating smarties?!?!? ������ That is ABSOLUTELY RIDICULOUS!!! YOU WILL BE SMARTER, IF YOU DO YOUR OWN RESEARCH AND DON’T BUY WHAT BIG PHARMA WANTS TO SELL YOU BY TRYING TO SHOVE THEIR GARBAGE DOWN OUR THROATS!!! ����‍♀️����‍♀️��

  • How can you compare Spirulina to Antihistamines which shut down the immune system to prevent the release of histamine. When you make videos like these you have a responsibility to viewers and comparing them price wise is very misleading.

  • First check you T4 levels thioryd before taking it. Coused me to have hypotheroid meaning that now my glans doesnt produce thiroxyne and can cause to gain weight. There is spirulina without iodine for these cases. Other from that its a great help to many things

  • Hello guys we are a company in west africa that can provide the purest spirulina,so whoever wants it in any quantity we can provide. The shipping also wont be a problem


  • Whey protein is so unhealthy though.

    Work out how much the spiralina ends up costing per serve & then it seems more worth it
    Sucks that it costs that much though
    But you can’t put a price on health
    Alternatively eat things like peanut butter & lentils for protein

    Dairy is never preferable over a plant

  • Bought Hawaiian spirilina (the same brand you sell on your website) but it makes me very thirsty… So not sure what to do… Keep taking or stop

  • recently i started taking spirulina, 2 tablets in the morning when i wake up and 2 in the night before i sleep, ever since i’ve began to have really bad stomach pains, i’m lactose intolerant so it’s nothing new to me, however the pain has become noticeably more painful and frequent. however i also take 2 magnesium tablets and 1 vitamin c tablet at the same time, however that’s never been too much of an issue for me. i take gnc spirulina, grown in the US, can you help me by telling me if i’m doing anything wrong?

  • I just bought some hemp powder and I watched your video on it and I bought some of this to Spirulina powder Will it hurt to put both them in the same smoothie? because they both have a lot of protein same benefits?

  • I want to consume chlorella or spirulana but I have my doubts since coral reefs are dying in certain parts of the world and also there’s a lot of toxins in the oceans from oil spills and other stuff.

  • Antihistamines are seriously damaging to your liver so I think I’d rather take spirulina. Steroids which I’m taking now for my sinusitis are also seriously damaging to the body, and spirulina means I don’t have to take it. I think you should seriously have any medical qualification given removed, because you don’t know what you’re talking about and I’m concerned there’s an alterior motive to this, like big pharma, this smells dodgy, please get him off youtube.

  • I wanted to ask something about chlorella but couldn’t find a video by Dr Axe referring to that. In any case here is my question: Will chlorella help with post viral fatigue? I am experiencing these usual symptoms after a flu and from what I know it’s chemicals and other things that cause this feeling of fatigue to force your body to rest more, so I made this guess that maybe chlorella could flush out the toxins and the chemicals that cause these awful feeling after viral infections? Please let me know if it’s safe to use and if I would be helped to feel better!

  • I purchased spirulina in local store that sold approved by FDA
    I have a history of hyperthyroid and after 10 years it was became hypothyroid my metabolism is to fast blood test of TSH is not normal i take eltroxin branded of LEVOTHYROXIN 100mc/g and 150 mc/g
    Almost 5years maintaining of this medicine i search in you tube and online shop about spirulina ang serpintina

  • Hi, thank you for this video I’ve noticed lots of people take spirulina. Everyone seems to say how good it is..on the flip side why is there a video on here saying it contains potent neurotoxins that scares me and makes me not want to consume it.. could you enlighten me of the facts?

  • The doctor didn’t do much research on this topic. Spirulina is not just for allergies. It provide numerous positive health effects, which are backed by scientific studies. Basically, it exhibits powerful anti-oxidant and anti-inflammatory properties that can mitigate a variety of medical conditions. It contains a significant amount of zeaxanthin, a carotenoid that can protect the eyes and other organ systems. At least one report also states it contains a good amount of ergothioneine, an anti-oxidant that the body preferentially accumulates in many tissues. Also, the doctor misrepresents its cost you can get a multi-month supply in organic quality far cheaper than that overpriced $26 packet he shows on video. IMO, it is one of the most cost-effective “superfoods” that you can buy. Unfortunately, it doesn’t taste than great, which limits its acceptance.
