NOW Spirulina supplements are a great idea - a natural green superfood concentrated with dozens of different nutrients. NOW offers very clean specially-cultivated spirulina in tablet, capsules and powder form, each of which is full of vitamins, minerals and other phytonutrients. But even the highest-quality spirulina is still an an algae, after all, and its dense concentration of nutrients gives it a correspondingly strong taste. So if you haven't used spirulina in the past, NOW Spirulina tablets or Vcaps are a better way to get all of its energizing and alkalizing benefits compared to using a powder. To really feel the effects of spirulina, do what NOW suggests and use 6 tablets per serving taken with food. Experienced spirulina users use the powder form, which we think tastes bets mixed into apple or white grape juice rather than acidic or tart juices. Most people experience increased mental and physical energy even after using spirulina (any form) for a only short period of time.
