When a doctor recommends without certainty.
Bertrand M., 45, GP at a Lyon 3ᵉ practice, 15 years of experience. Bought ELITE 9K in April 2026 after reading the HYX 7-study corpus.
Bertrand has 3 long-COVID patients (chronic fatigue, brain fog, exertional dyspnoea) who respond to no conventional therapy. In May, he offers them an informal 8-week trial with ELITE 9K: « I promise you nothing, but Ohsawa 2007 documents a cerebral antioxidant effect. Let's try. »
Bertrand's methodical follow-up: patient symptom journal + Chalder fatigue scale + Effort Fatigue Scale (EFS) at T0 / T+4 wk / T+8 wk. Not randomised, not placebo. Pragmatic.
Returns at T+8 wk (August 2026): 2/3 patients report subjective improvement (Chalder −18% and −22%). The 3rd patient: no change. Bertrand: « Not proof, but a signal that warrants an RCT. I'll continue to suggest this to my treatment-resistant long-COVID patients. »
3 patients 8-week follow-up · 2/3 Subjective improvement · −20% Mean Chalder score
« When a doctor honestly documents 'not proof, but a signal', that's what we ask of medicine. »
