Upcoming Speaking Engagements
2026 Mexican Congress on Ophthalmology (Monterrey, Mexico)
"Natural compounds to reduce oxidation and resolve inflammation"
06/02/26
Description:
Chronic inflammation and oxidative stress are central contributors to many ocular and systemic diseases, yet they are often misunderstood. In this talk, Jim Stringham, PhD, will define and differentiate these two processes, explain their underlying causes, discuss the conditions they influence, and explain how key, powerful antioxidant nutrients can significantly reduce oxidation and inflammation. The session will summarize the relevant nutrition science that supports a preventative approach to health, and outline practical approaches for addressing chronic inflammation to support long-term health and disease prevention.
2026 International Symposium on Carotenoids (Palma, Spain)

"Effects of Macular Carotenoid Supplementation in Impact Athletes"
Description:
Introduction and Objective: This randomized, placebo-controlled nutritional intervention study examined visual structure and function, and blood biomarkers associated with neurodegeneration throughout a season of repetitive head impacts (RHIs) in rugby athletes. Athletes in the treatment group were supplemented with 22 mg of macular carotenoids (MCs) and 300 mg of omega-3 fatty acids.
Methods: Optical coherence tomography was employed to assess visual structure. Bioavailability of the supplement was assessed via skin carotenoid concentration (SC). Contrast sensitivity (CS) and critical flicker-fusion frequency (CFF) were used to measure visual function. Blood levels of NF-L, GFAP, and UCH-L were analyzed to determine changes incurred from RHIs.
Results:Thirty-one rugby players (15M/16F; 19±1.4 years) were randomly assigned to supplement (SG; n = 15) or placebo (PG; n = 16) groups. In both groups, left eye ganglion cell complex inferior region was significantly thinner post-season (SG: 102.1±4.4 vs 102.9±4.7 μm; p = 0.002; PG: 101.4±5.3 vs 102.6±5.0 μm, p < 0.001). Versus the PG, the SG had a higher SC score at post-season (409.2±76.3 vs 323.4±61.3; p = 0.04). CFF approached significant increase in the SG versus PG (27.6±1.8 vs 25.7±2.2 Hz, p = 0.08); there were no differences found between groups in CS. NF-L was elevated post-season in the PG (10.05 vs 7.21 pg/mL; p = 0.003) but not the SG (7.07 vs 7.78 pg/mL; p = 0.40). The changes in GFAP were similar, approaching significance in the PG (p = 0.12) but not the SG (p = 0.97). Change in UCH-L1 was not different between groups.
Conclusions: One season of collegiate rugby resulted in retinal thinning and increased concentrations of NF-L and GFAP in the PG versus SG. Supplementation with MPCs and omega-3s may be useful in limiting the inflammatory cascade associated with RHIs.
