AstaReal wins NutraIngredients-Asia Award for first clinical trial on children’s digital eye health
The recognition comes for conducting the world’s first clinical trial on digital eye health in children, with the study published in Advances in Therapy.
The trial demonstrated that astaxanthin supplementation can effectively reduce both chronic and acute digital eye strain whilst enhancing objective measures of visual performance.
In the clinical study, school-aged children received a daily dose of 4 mg of astaxanthin (AstaReal) for 84 days.
The findings indicate a significant improvement in chronic digital eye strain in the astaxanthin group compared with placebo, demonstrating a 20% greater reduction in the CVS (Computer Vision Syndrome) symptoms score by the end of the study.
The results also showed a 27% improvement in visual fatigue (acute digital eye strain) as well as improved stereopsis and pupillary light reflexes after the trial period.

Yeah, they pulled out a small change in one of the parameters. And the placebo group also seemed to get better over time too.
I thought lutein and zeaxanthin were the go-to for eye health, eye strain etc. Though Astaxanthin is a powerful antioxidant, so I guess it’s plausible to be helpful here.
Exactly correct. Lutein and zeaxanthin (and mesozeaxanthin) are most absorbed by tissues in the eye and most biologically significant. Astaxanthin is absorbed too, but to a much smaller extent, and doesn’t seem to do anything beyond what the former accomplish. I posted a ton of papers in various threads on all these carrotenoids and the eye.
I’ve read the 2019 safety review paper. While the maximum safe dose for natural astaxanthin seems quite high, I’m unsure about the safety of synthetic astaxanthin.
I know of people taking synthetic astaxanthin, such as Siim Land has been taking 24mg of synthetic astaxanthin daily for a year. Does anyone else have experience with synthetic astaxanthin?
I’m currently taking 3 ZanthoSyn capsules daily, which is 12mg * 3 = 36mg of synthetic astaxanthin. My liver enzyme levels are normal, but compared to the dosage for ITP, it seems insufficient. I plan to increase it to 12mg * 4 = 48mg. What are your thoughts, or are there any research papers I could refer to? Thank you.
I only did it for a week or two - then (because everything the Asta powder touched seemed to stain red, and I was concerned about my teeth) I stopped. I haven’t had time to devise a solution (e.g. encapsulation, etc.). It’s the Dutch company I sourced from. Synthetic. See this discussion: Astaxanthin, Natural vs. Synthetic - Your Thoughts?
