Lutein reduces inflammation in TAO

Hei X, Lin B, Wu P, Li X, Mao Z, et al. Lutein targeting orbital fibroblasts attenuates fibrotic and inflammatory effects in thyroid-associated ophthalmopathy. Exp Eye Res. 2023;232:109515. doi:10.1016/j.exer.2023.109515

We investigated how lutein might help with thyroid-associated ophthalmopathy (TAO), a condition marked by inflammation and fibrosis. In our in vitro study, lutein was applied to orbital fibroblasts before introducing fibrotic and inflammatory triggers.

We observed that lutein reduced important markers related to fibrosis and inflammation, such as ACTA2 and IL-6, while also curtailing cell migration. The research highlights lutein's possible therapeutic role due to its ability to inhibit harmful processes seen in TAO, suggesting it could be a promising treatment option.

This worked! I went to America for a while and had to drive. I discovered this supplement on iHerb, ordered it, and started taking it. Within a week, I was able to drive without discomfort, which was really helpful. Recommended.

Bone Pain details

My eyes no longer hurt when I work on computers. I had begun experiencing pain whenever I looked at the screen for too long, which worsened over time. Since I discovered lutein, that pain has completely disappeared, and I find it indispensable. I also recommend it for computer workers suffering from eye discomfort.

Carotenoids linked to heart health

Chen M, Cai S, Jia Q, Suo Y, Tang Y, et al. Inverse Relationship Between Serum Carotenoid Levels and Cardiovascular-Kidney-Metabolic Syndrome Among the General Adult Population. J Diabetes. 2025;17:e70046. doi:10.1111/1753-0407.70046

We explored the relationship between serum levels of carotenoids, like lutein, and cardiovascular-kidney-metabolic syndrome in over 1,600 U.S. adults. Through extensive analysis, we found that higher lutein levels corresponded with a lower likelihood of advanced CKM syndrome. Other carotenoids also showed similar protective effects, but β-cryptoxanthin did not demonstrate any significant benefit. This suggests that increasing intake of carotenoids, especially lutein, may be a smart choice for heart health.

Eases visual fatigue

I spend the entire day at the computer, but since I began consuming this, I can see clearly even in the afternoon when I'm weary, and I have noticed that my fatigue and dry eyes have improved.

We investigated the relationship between carotenoid levels in the blood and the prevalence of severe headaches or migraines among US adults. Using data from over 8,900 participants in the NHANES survey, we found a noteworthy inverse association between levels of lutein, zeaxanthin, and several other carotenoids with the incidence of migraines.

While these findings suggest that carotenoids might offer some protective benefits, further research is needed to confirm these results and understand how they work.

Lutein shows promise for heart health

Abdelmonem M, Ibrahim SM, Essam RM, Amin HAA, Abd-Elmawla MA. Lutein exerts its cardioprotective effect against the experimental model of isoprenaline-induced myocardial infarction via MIAT/miR-200a/Nrf2/TXINP pathway. J Biochem Mol Toxicol. 2021;35:e22899. doi:10.1002/jbt.22899

We examined the potential of lutein to protect against heart damage caused by myocardial infarction, using a model induced by isoprenaline. The study showed that pretreating rats with lutein significantly reduced heart injury markers and improved heart function compared to untreated individuals.

Notably, lutein not only decreased damaged heart cells but also positively influenced several protective pathways at the molecular level. However, while the results are promising, they indicate that further research is necessary to fully understand lutein's role in heart health.

Lutein is excellent! The quality is commendable, and I will repurchase if necessary. It enhances "dark adaptability," filters blue light, and improves "visual adaptability" and "recognition function." It also aids in preventing "macular degeneration," lowers the risk of "cataracts," alleviates "visual fatigue," and protects the "crystals" of the eyes. Furthermore, it aids in preventing the "sequelae of high myopia," reduces the incidence of "glaucoma," improves "brain health and cognitive function," and helps prevent "cardiovascular" and "metabolic diseases."
