The attached pic was taken in Nov. 2019 when I was 68. I only use it in smoothies, so if I am not drinking smoothies for awhile, I don't always use it. But I have been using it CONSISTENTLY, as in pretty much everyday, for awhile now. PROS: ENERGY - THIS is the BIGGEST pro for me. From the first time I had spirulina in a smoothie, I was amazed. I didn't expect to feel the boost of energy it gave me. And not like the kind from caffeine. Sustained energy. OTHER BENEFITS: Feel it makes my skin look better, I just FEEL better, I feel it helps with aches and pains and just makes me feel and be healthier. FLAVOR - OK, it's not what you would call tasty on it's own. I LIKE the taste IN MY SMOOTHIE, but not something like wheatgrass I could do shots of. BUT I mix in with choc PlantFusion protein powder, almond milk, wild blueberries and about a tsp of this and I am FINE with the taste. QUALITY - I haven't found a better quality spirulina. My advice? RESEARCH yourself and see if you find something you think is more pure or better quality. Check where it comes from, what kind of checks are done on it and go with what you feel is best. After well over a decade, best I have found, but if you find something better, please comment and let me know! QUANTITY FOR PRICE - for the amount you get, the quality, I am HAPPY with the price. I just buy this for myself and just use about a teaspoon. I often get the smaller jar, just because, even though larger more cost effective, I like opening fresh product about every six weeks. AND FYI, read the exp date! WHERE TO GET IT: I STRONGLY suggest getting it SOLD BY NUTREX AND SHIPPED BY AMAZON OR SOLD AND SHIPPED BY AMAZON. SOME vendors are better than others and I always am happy with buying it this way. SO FIVE STARS! Read more
