Spirulina, aka blue-green algae, is bursting with vitamins and minerals and makes a great nutrient rich substitute for protein powders. Spirulina is easily digested, due to its lack of cellulose cell walls, which means its nutrients are more bio-available. If you're looking to keep your immune system healthy, Vimergy's USA Grown Spirulina is the perfect addition to add to your daily regimen. Now available in capsules for when you're at work, traveling, or on the run! Plus contains no additives or fillers. 100% Pure.
