When vitamin C levels are low, correcting them makes sense. But in this study, we found no evidence that each person needs a personalized vitamin C supplementation.

Happy to share our publication in FRBM. We used aggregated sets of n-of-1 trials to study individual oxidative stress & inflammation responses to vit C supplementation. Huge thanks to @lorenzololli.bsky.social @gregatki.bsky.social @mg-nikolaidis.bsky.social www.sciencedirect.com/science/arti...

🚨LEAD FEATURE ARTICLE🚨 November 2025✨ We are very excited to announce our lead feature article for the November 2025 by Lolli et al titled ‘Understanding Treatment Response Heterogeneity Using Crossover Randomized Controlled Trials: A Primer for Exercise and Nutrition Scientists’.

It was a rewarding labour of love to work on this paper with a fantastic team of authors, “Understanding Treatment Response Heterogeneity Using Crossover Randomized Controlled Trials: A Primer for Exercise and Nutrition Scientists”. @hk-ijsnem.bsky.social journals.humankinetics.com/view/journal...

Your intuitions about individual responses to training are probably wrong 😉 👇🧵 1/11

This is a very interesting study comparing physiological variables between two phases of the menstrual cycle across two whole cycles. The design resembles a replicate crossover trial which enables proper study of individual responses. physoc.onlinelibrary.wiley.com/doi/10.1113/...

I'm grateful to the SFRR-E for the ECR Fellowship (@sfrre-ecr.bsky.social) which made the RedoxOne project a reality. Otherwise, it would still be an idea saved in the “future studies” word file! #redox #antioxidants #exercise #nutrition #Nof1 #interindividual_variability #galway

Vitamin C+E supplementation blunts molecular adaptations to sprint interval training but not performance gains. Since performance wasn’t impaired, I wonder whether, and to what extent, the blunted molecular responses can truly be considered detrimental physoc.onlinelibrary.wiley.com/doi/10.1113/...

Hats off to them for publishing that paper without mentioning n-of-1 trials or person-by-treatment interactions 😬. We've this paper currently under review. It's frustratingly long-winded, but that's the complex nature of the precision nutrition beast I suppose, osf.io/preprints/os...

James Imlay turns redox chaos into clockwork: his new paper shows how membrane permeability sets the tempo of oxidative stress, with straight-up back-of-the-envelope math in the appendix. Fundamental, elegant, causal. onlinelibrary.wiley.com/doi/10.1111/...

📢 Exciting Webinar Alert! Join us tomorrow, April 1st, at 15:00 CET for an unmissable webinar on chaperones in redox biology, hosted by @sfrre-ecr.bsky.social! We’re thrilled to welcome two fantastic speakers: @ulrichlab.bsky.social and @rsutandy.bsky.social. See you there!

Good to see this paper finally published in EJON, after a strange prior experience with another journal, "Inter-individual differences in the blood pressure lowering effects of dietary nitrate: a randomised double-blind placebo-controlled replicate crossover trial" link.springer.com/article/10.1...

Study shows that chronic antioxidant supplementation (VitC+VitE) blunted molecular adaptations to training, yet, no impact on any measure of exercise performance—considering that "antioxidant" is a vague term and that VitC+VitE may not always act as such. www.biorxiv.org/content/10.1...

Great redox researcher to follow and excellent review in the redox biosensors field!

Important study highlighting plausible molecular links between redox metabolism and exercise performance—an area notoriously difficult to dissect. The findings challenge assumptions that G6PD deficiency decreases exercise performance. A human replication study would be invaluable.

G6PD deficiency affects 6% of humankind, predisposing RBCs to hemolysis after oxidant stress. Unexpectedly, humanized G6PD deficient mice do not hemolyze after oxidant stress post exercise, and tolerate exercise better! On the cover of @bloodadvances.bsky.social ashpublications.org/bloodadvance...

99% of the circulating cells, 84% of the cells in the body are RBCs. These 25 trillion cells shed 1 vesicle/h (more under stress). With >250 transporters and receptors, RBCs pick up/release metabolites, at times even against gradient, throughout the body. Yet, they are not part of 👇 conversation

Free radicals and antioxidants: appealing to magic Our short paper argues that molecules cannot be classified as good or evil. Limited evidence supporting the consumption of antioxidants or superfoods and such interventions risk disrupting fundamental redox processes. www.cell.com/trends/endoc...
