What The Differences Mean
NOW’s title and Supplement Facts support 1,000 mg spirulina per tablet, while a separate retailer potency field says 100 mg. Pines lists 500 mg in the title but no total barley-grass amount in its Facts table. Both discrepancies remain visible; neither product is treated as a replacement for vegetables or a detox treatment.
