ABSTRACT:
A stable concentrated dietary supplement containing fucoxanthin as the main active component. The dietary supplement is made by a process including grinding crude freeze-dried flakes of wakame seaweed (Undaria pinnatifida) with desirable characteristics into a powder, extracting the active fucoxanthin from the powder with use of an aliphatic or aromatic organic solvent, then filtering and distilling the extract to form a thick syrupy fucoxanthin-containing mass having a solids content of from about 10-99% by wt. The mass is then purified by dissolving it in an organic non-polar solvent having a Polarity Index of <6, wherein the resultant solution is filtered to remove any solid material therefrom and the remaining liquid is then concentrated to a dried mass by removing substantially all of the solvent, which mass is thereafter ground and sifted to obtain a plurality of particles measuring approximately 60-100 mesh in size. The supplement contains at least about 10% by weight of fucoxanthin, less than about 1 ppm iodine and less than about 1 ppm arsenic, and the fucoxanthin contained in the supplement remains substantially stable for at least about 2 years. The particles by themselves, or in admixture with other components well known in the relevant art, comprise a supplement that may be constituted in a form selected from, for example, tablets, capsules, powders and granules.
