In a new study, Fuji Health’s (Burlington, NJ) brand of natural astaxanthin extract (AstaREAL) derived from Haematococcus microalgae was detected in the iris/ciliary body of New Zealand albino rabbit eyes 24 hours after ingestion, the company announced on January 6.

In a new study, Fuji Health’s (Burlington, NJ) brand of natural astaxanthin extract (AstaREAL) derived from Haematococcus microalgae was detected in the iris/ciliary body of New Zealand albino rabbit eyes 24 hours after ingestion, the company announced on January 6.

Astaxanthin has been reported to have benefits in the eye such as the alleviation of eye fatigue in visual display terminal (VDT) workers after oral supplementation. However, up to now there has been no intraocular kinetic information available.

Researchers at Kanazawa Medical University (Ishikawa, Japan) and Fuji investigated the ocular and blood serum levels of astaxanthin in 24 NZW albino rabbits. After administering a 100 mg/kg single oral dose, astaxanthin was determined by extraction followed by HPLC analysis over a period of 168 hours.

Further human study is necessary.
