Good question. I take a teaspoon on a daily basis with a morning shake. I've never noticed any negative side effects, but I've never noticed any positive ones either.

According to nutritiondata.com, spirulina has some of the highest thiamine content of all foods per 100-gram serving. Along with magnesium and manganese (found in agar seaweed), thiamine seems to be one of the nutrients that always comes up short of the RDA on a paleo/carb restricted diet. Since the competition at that level is mostly nuts high in omega-6, spirulina would be a far healthier choice.

I just ran across an article on runningtimes.com (http://runningtimes.com/Article.aspx?ArticleID=19368) comparing spirulina to chia seeds for performance. It stated an improvement with spirulina. I hadn't heard of it before. I found some at GNC that wasn't too expensive and didn't have any additives. I've been trying about 2000mg a day (1k in the morning and 1k at night) and it's hard to say, but I seem to have more energy on my running workouts. I also noticed that I seem to stay satiated longer regardless of what I eat. Just my anecdotal experience. I only started using it for athletic improvement. I already take Omega-3 supplements as well as chia seeds daily for dietary supplementation.

I'm lactose intolerant and a graduate student, and I supplement with spirulina. I've been using it for the past couple of months and I have nothing bad to say about it.

I also find that I'm satiated longer after consumption, although I don't believe the spirulina to be the primary factor in this.

Good to know about the thiamine as I'm not a heavy consumer of nuts.
