How to read XP
Each score is for this supplement and that specific goal, not a general rating.
XP combines how reliable the research is with how much difference it usually makes. Higher means stronger evidence for that supplement and that goal.

Your journey
Headaches / Migraines comes first (week 4 → month 3); Fertility (Men) takes longest (month 3 → month 6). An estimate from the studies' timelines, not a promise: everyone responds differently.
From the first noticeable effect to roughly full strength. Colour follows the XP tier of each benefit.
Make it a habit
These gains come from steady use, not a single dose. Keep CoQ10 in your routine for about month 6 before you judge it.

- Promising but not provenEarly results look encouraging, but the trials are small — treat this as a modest, unproven option rather than a reliable fix.
Check with a doctor first if you take warfarin (CoQ10 may reduce its effect) or statins (it's sometimes used to offset statin-related muscle aches, but check first).
General information, not medical advice. If you are pregnant, take medication or have a health condition, check with a doctor or pharmacist first.
