Question explored with the scientific record
Conversation so far
- 1 tests alpha-lipoic acid plus creatine against creatine alone and creatine plus sucrose. It found that the lipoic acid combo boosted muscle creatine stores more than either of the other two. so how can i get an intake of th elipoic acid combo in everyday life + a private exchange
- 2 how can i make a creatine-plus-sucrose combo...in a drink or other wource + a private exchange
- 3 did it help long covid patients

Ostojic et al., 6-month trial (Food Science & Nutrition): https://pmc.ncbi.nlm.nih.gov/articles/PMC10630839/ creatine helped long covid
The short version: one small trial says creatine helped, but the evidence is too thin to trust.
The Ostojic trial [1] is the only record that directly tests creatine for long COVID. It gave 12 adults with post-viral fatigue syndrome 4 grams of creatine monohydrate daily for six months and reported improvements in fatigue, exercise tolerance, and several symptoms. But the sample is tiny — 12 people — and the trial was published in a journal called Food Science & Nutrition, not a top medical journal. There is no funding disclosure in the evidence record, so we do not know who paid for it. The same research group also published a second study [1] that measured creatine levels in the muscle and brain of 19 long COVID patients and found they were low, which is a plausible mechanism but not a treatment trial.
The rest of the evidence covers creatine in healthy soldiers [3], older adults [6], and athletes [4]. None of it tests long COVID. The 1999 study [4] even found that creatine loading raised muscle creatine levels but did not improve sprint performance — a reminder that a biochemical change (higher tissue creatine) does not automatically translate to a clinical benefit.
| Study | N | What it tested | Key finding |
|---|---|---|---|
| Ostojic 2025 [1] | 12 | Creatine 4 g/day vs placebo, 6 months | Improved fatigue, exercise tolerance, symptoms |
| Ostojic 2025 [1] | 19 | Creatine levels measured in muscle/brain | Levels low in long COVID, correlated with myalgia |
| 1999 study [4] | 14 | Creatine loading, 5 days | Muscle creatine rose, but no performance gain |
My call: one small trial with no disclosed funding source is not enough to recommend creatine for long COVID. The mechanism is plausible but unproven. Confidence: low.

Creatine supplementation increases muscle total creatine but not maximal intermittent exercise performance
Creatine loading increases muscle total creatine and creatine phosphate but does not enhance maximal intermittent sprint performance, with observed performance gains in both groups likely due to placebo effects rather than the supplementation.
