Hi, just wondering if anyone can help me. I began using spirulina a week ago and already I feel energized and better able to cope with life..i haven't had a cold sore for years but yesterday had a outbreak..after some research I found spirulina has high arginine which causes herpes outbreaks yet some people swear by it as a prevention because it boosts the immune system..i really don't want to stop having it because I love the results but not the cold sores..could this be the cause?

Hello there!!!

I've been taking spirulina in capsules for couple of weeks... started from one a day now I am up to 3... First week I did not feel anything different...but last 4-5 days I have very bad headaches and have no energy... not sure if I have to just keep going and it will go away...

But I do not want to take one pill .. and then take another to get rid of side effects of previous pill..

How long you supposed to feel side effects till your body adjust to it? I know everyone is different but I am close to giving it up!!

Thank you )

I just started taking spirulina (Now brand, certified GMO free) about a week ago, recommended dose on label is 6 tablets, on the 4th day of taking it I got flu like symptoms including vomiting for 3 days, I stopped the supplement during that time, not sure if this was from the spirulina or not, now I am afraid to take it again. This was the worst sickness I have had ever, whether it was the flu or reaction to the spirulina. It gave me a strange, uncomfortable feeling in my stomach and as a result I could not sleep.

I consume Elken Spirulina few days ago. I took 7tablets daily. I noticed that I got a sore throat after taking the pills. I think it is the side effect. Should I reduce the amount of the pills?

Add me to the list of those negatively affected by Spirulina. Here's how we 'accidentally' figured it out.

A while back I tired of doing spirulina powder. I just couldn't do it anymore. So I tried Pacifica pills. The first time I took the pills I felt uneasy after an hour or so and proceeded to vomit more violently than I have in my life (39 yrs old). A firehose out the other end and I was miserable for a day. I vowed off spirulina.

My wife made me a smoothie this morning and I went to work as normal. An hour later I clearly remembered the same feeling happening. I was deja vu back in the bathroom at work violently vomiting and having diarrhea . I texted my wife to ask what she put in the smoothie and sure enough she put in a green powder mix that had spirulina as an ingredient. So if anyone wants to play a bad joke on me, they can slip me my smoothie with spirulina. It's just strange that it happened after I switched from the full powder.

I've had a bad relation to spirulina as well. I took it in powder form (1/8 teaspoon) and have had severe headache, vomiting and diarrhea for hours after. This has happened again after a break of not taking it so I am sure spirulina is the cause.

I also had a bad reaction to spirulina pacifica. I took the pure Hawaiian powder type from a natural health food store.

I vomited 2 hours after putting 1 tsp in my green juice drink. I vomited for a whole hour along with diarrhea. I know its the spirulina because the same thing happened a week ago. I didn't think it was the spirulina because my husband had the same drink and he was fine. I must be allergic to it if that is possible. I will never take that stuff again.

Warning

WARNING!! To all those who have had vomitting, etc after ingesting chlorophyll based supplements. This is an allergic reaction! Don't kid yourself into thinking this is detox like I did or let anyone else tell you otherwise. Vomiting, cramps and diarreha are the reactions of the mast cells in the digestive tract. After being rushed to Emergency two nights ago after I again ingested a form of chlorophyll, the medical team warned me that the next time may kill me. Thank god my sister is a physician and insisted my husband to take me after he called her. I thought a food allergy was when you have a anaphalactic reaction but they explained how it all works. See WebMD's page on allergies for a brief but good summary.
