A Japanese patent states a small dosage of phycocyanin daily
maintains or accelerates normal control cell functions that prevents
generation of malignancy such as cancer or inhibits its growth or
recurrence.22 The patent recommends a phycocyanin dosage in a
range of 0.25 to 2.5 grams per day. Spirulina from Earthrise Farms,
California and Siam Algae, Thailand have a high 15% phycocyanin
content. This means the patent recommended adult dosage would be
filled by consuming 1.7 to 17 grams per day, making about ten grams
a day a useful level.
