Shortlists, and the reasoning.
How to narrow a category down yourself: define the job, match the doses, then compare the cost of a labelled serving. These are methods, not rankings.
Ashwagandha: Which brand is the best to buy in 2026?
The best ashwagandha is the one that matches the trials: a named root extract, 300 to 600 mg a day, with nothing hidden. We read six US labels. NOW’s 600 mg KSM-66 is our pick at about 37 cents a day; Jarrow’s 300 mg capsules suit a split dose; NOW’s 450 mg extract is the budget choice. Gummies cost four times as much a day and add sugar and vitamin D.
Editorial guideI tried 9 protein powders: here are the best 2
Nine protein powders, nine lab reports. Every one passed Labdoor’s tests, but only six had no heavy metals detected at all. Of those, NOW Sports Whey Protein Isolate delivered its label to the gram with the highest share of protein in every scoop, and Naked Egg beat its label as a dairy-free egg-white protein. Here is how all nine ranked, and why.
Editorial guideHow to build a supplement shortlist
A practical selection method: purpose, disclosed amounts, evidence and total cost.
Editorial guideThe best GLP-1 supplements for weight loss in 2026, ranked
Every GLP-1 supplement we have reviewed in full, ranked by the same five criteria as our reviews. One has randomised trials measuring both GLP-1 and weight on its own extract — and even that one does roughly a quarter of what the drugs do.
Why there is no number one
A ranking has to assume everyone wants the same thing. In supplements that assumption breaks immediately: a fibre powder, a relaxation formula and a vitamin D softgel are not competing for one crown, and the right choice depends on a gap you are trying to close rather than on a score somebody else assigned.
So these guides teach the selection instead of performing it. Define the job in one sentence, list the candidates with their disclosed amounts, check whether the research used that form and dose, then compare what a labelled serving actually costs. The shortlist you end up with is yours, and you can redo it when a formula changes.
Where a shortlist usually goes wrong
- Comparing bottle prices when one product needs three capsules a serving and another needs one.
- Treating a proprietary blend as a single ingredient, when it hides how much of anything is in there.
- Accepting a study as support without checking it used the same form, dose and population.
- Reading a certification badge as a batch test result, when it may be neither recent nor specific to the bottle.
Start from a category
Every label overview sits in one of three categories, each with a guide covering the ingredients that come up most often and the questions worth asking about them.
