Liz,
While I do not take the Spirulina in capsule form, I have for 20+ years taken it daily in powdered form as part of both my morning smoothie and afternoon green drink. Blending provides enough drink for consumption over a couple days duration, so within in each glass which is consumed there averages just under a half tea spoon of Spirulina. My family and I are in the camp which views Spirulina as one of the true super foods and highly recommend it.
We purchase Pure Hawaiian Spirulina Pacific. Last acquired was through Amazon a couple months back at $23.79.
Regards,
Larry
