Researchers have shown that the carotenoid phytoene increases the lifespan of the nematode Caenorhabditis elegans and can slow the onset of paralysis associated with the formation of amyloid plaques in a model of Alzheimer's disease.
Specifically, increases in longevity of between 10% and 18.6% and decreases in the proteotoxic effect of plaques of between 30% and 40% were observed.
The studies tested pure phytoene and extracts rich in this carotenoid obtained from microalgae.
According to Dr. Paula Mapelli Brahm, "These are very exciting preliminary results, so we are looking for funding to continue this line of research and to find out by what mechanisms these effects are produced."
Caenorhabditis elegans is a widely used animal model in biomedicine. In fact, it has been instrumental in important discoveries that have been recognized with the Nobel Prize, such as programmed cell death, RNA interference and applications of the GFP protein.
Professor Antonio Jesús Meléndez Martínez's team has spent 15 years studying phytoene, which is found in foods such as tomatoes, carrots, apricots, red peppers, oranges, mandarins and passion fruit, among others. It is a compound that is efficiently absorbed and found in many tissues, including the skin, where studies indicate that it can protect against ultraviolet radiation.

When I read the news of this to my nematode Caenorhabditis elegans, they were overjoyed.

Looks like the tablets are inexpensive: $0.04 ea in the 600 tablet container.

If it’s only one nematode, you should have said “it,” not “they.”
