I purchased recently from Faridabad. Batch Number SPC-9001, Mfg Date 01/2009, Best Before 12/2011
I opened the capsule, it is transparent and has dark green powder inside it. Hope its genuine. I think the one that you got might be from a scruplous source who can't care less about the public health and also the authorities are responsible for this.
Gagandeep, I think that eating algae would be classified as non-vegetarian, if you think in that sense. Thus, the Red sign is appropriate.
Nathan, I would like to know, since you have been taking spirulina for many years, what positive/negative results do you feel with its consumption?
