Our method
How a product earns its spot.
The stack is a short list on purpose. A product has to pass all three filters before we feature it.
Research-driven brands
We pick brands that invest in research and stand behind their formulas with published studies. We link the research so you can read it yourself.
Trusted quality
Third-party certifications and clear labels, so you know what you are getting.
Value for everyday use
Products people keep at home and use consistently. Fair price per serving, simple to take, easy to trust.
1. Research-driven brands
We feature brands that invest in research and stand behind their formulas with published studies. On each product page we summarize the research on the main ingredients, from position stands by groups like the International Society of Sports Nutrition to meta-analyses and randomized trials in people, and tag it by evidence strength: strong, mixed, limited or everyday nutrient. We link every study we cite so you can read it yourself.
2. Trusted quality
Supplements are not approved by the FDA before they are sold. We look for products that carry third-party certifications, such as NSF Certified for Sport or Informed Choice, as listed by the brand, and clear labels that show every ingredient and amount, with no proprietary blends. When information comes from the brand, we say so.
3. Value for everyday use
The stack is built from products you would keep at home. We look at price per serving, how easy it is to take, and what customers commonly report in public reviews.
What we don't do
- We don't rank or pit products against each other. We showcase the ones that earned a spot.
- We don't say a supplement treats, cures or prevents any disease.
- We don't accept payment to feature a product.
- We don't lab-test products or verify labels ourselves. We rely on published research, third-party certifiers and information from the brand.
- We disclose limitations. If part of a formula has limited evidence, the product page says so.
Every week, the stack grows
A new product joins every week. If new research changes the picture on a product already in the stack, we update its page and note the date.
