Understanding supplements.
How do I evaluate what I'm actually buying — in an aisle with one withdrawn scandal?
The migraine supplement aisle is paradox country: it contains three genuinely trialed nutrients (magnesium, riboflavin, CoQ10) — and it contains butterbur, the herb that was genuinely effective, then withdrawn from professional recommendations over pyrrolizidine-alkaloid liver toxicity and contamination that could not be guaranteed out of the supply. That history sets the evaluation standard here: trial evidence, dose transparency, and safety record — in that order, with no nostalgia.
Capsules
Standard for all three nutrients
Softgels
CoQ10 — take with fat
Powders
Magnesium — dose math matters
Gummies
Dose-capped — a red flag here
Oxide / Citrate (Trial Forms)
The salts the 600 mg trials used — cheap and elemental-dense, with citrate absorbing reasonably and oxide poorly; both tax the gut at high dose, and loose stools are the built-in ceiling.
Glycinate (Tolerability Form)
Chelated and gentle — the practical choice for reaching high daily elemental doses without GI revolt. The trade is capsule math: at ~100–200 mg elemental per capsule, the studied range means 3–6 capsules daily. Count elemental mg, not compound weight.
Choosing the Right Form & Dose
Label literacy in the migraine aisle has three specific jobs:
- Elemental magnesium math: count mg of elemental magnesium across the day's capsules — the trials dosed ~600 mg elemental, and labels often print compound weight to look bigger.
- Riboflavin: the one-capsule season: 400 mg daily for a full 3 months before judging — the cheapest, most-forgotten discipline in the category.
- CoQ10 with fat, three times or 300 mg once: whichever pattern you'll actually sustain, with the warfarin conversation first if it applies.
- The standing rule: check every 'migraine formula' for butterbur by every name (Petasites) — and walk away from blends that stack it or hide it.
Red Flags to Watch For
The migraine aisle contains the supplement industry's clearest withdrawal story:
- Butterbur / Petasites hybridus — genuinely effective in trials, then withdrawn from professional recommendations over pyrrolizidine alkaloid contamination causing liver toxicity and carcinogenic risk. 'PA-free' claims are not a supply chain you can verify. Avoid entirely.
- 'Migraine relief' proprietary blends stacking feverfew, butterbur, magnesium, and B2 at sub-therapeutic doses — each ingredient below its studied level, borrowing every study collectively.
- Feverfew standalone — older evidence base, inconsistent trials, quality issues; not the scandal butterbur is, but not the evidence the three nutrients above carry either.
- High-dose 'energy' CoQ10 marketing that borrows migraine trials to sell 400 mg+ heart-health doses — the migraine trial pattern was 300 mg/day, and dose is part of the claim.
