Use a six-column mental spreadsheet
For each product, record: intended outcome, active ingredients, amount per serving, extract/standardization details, evidence level, and commercial terms. This prevents a dramatic landing page from substituting for a meaningful comparison.
Evidence levels
Mechanism asks whether a compound plausibly interacts with a pathway. Ingredient human evidence asks what happened in trials of a specific ingredient. Finished-product evidence asks whether the actual combination was studied. These levels should never be silently merged.
Do not reward ingredient count
Eleven ingredients are not automatically better than seven. A smaller formula can be easier to evaluate; a larger one can provide more pathways but also more interaction and attribution complexity. Dose, extract quality and evidence matter more than count alone.
Commercial comparison
Compare total cart price, servings per bottle, shipping, return conditions, one-time purchase versus subscription, and whether a guarantee requires returns. See the HorseWood package snapshot for an example.
