Abstract

When a tablet is formed from blue-green algae powder alone, there are problems such as a deteriorated tableting ratio due to breaking, cracking, and the like and collapse due to moisture absorption and the like. During the formation of a tablet, an excipient such as a sucrose fatty acid ester and dextrin, and a binder need to be added, but the tablet recently does not satisfy a preference of consumers who would like to avoid the additives. The inventors of the present invention have done intensive study to solve the problems, and as a result, found that a formulation with blue-green algae powder and α-linolenic acid improves the tableting ratio of a blue-green algae-containing tablet, and completed the present invention.
