Does anyone have any experience or insight on this supplement?
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.
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'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.
