How our curation process works
1
Search
Superpower has a dedicated research team that searches the world for the most scientifically rigorous, highest quality, purest, and trustworthy products.
Each year, we review over 10,000 products to carefully select and curate the top 1%.
Our research team uses a combination of qualitative and quantitative algorithms to score brands. We set a high benchmark: only those brands that score a 90% or above meet our standards.
In a world with more options than ever, we’re committed to being the one place you can trust.

Evaluate
Each product then undergoes a comprehensive vetting process over a six-week period. This extensive time window allows us to delve into the details of each standard. Brands are ultimately signed off on by our review committee of leading doctors, scientists, and pharmacologists.
We evaluate products across 11 factors, here are a few of our most important:
2.1 Evaluate
Scientific Rigor
Products should have substantial evidence from peer-reviewed studies. We scrutinize the science to ensure the product is safe and effective. We review how long the supporting science has been around, the strength of the scientific advisory board (SAB) behind it, and the quality of the publishing scientific journal.
This also includes assessing the years of data; the number of supported peer-reviewed articles with large sample sizes and proper randomization (double-blind, placebo-controlled); meta-analyses where present; strong support from scientific experts; and whether studies were done primarily on humans vs animals vs in vitro.

2.2 Evaluate
Ingredient Quality
Supplements and wellness products are not regulated by the FDA, so we’ve created our own criteria for what’s considered safe versus not with a NO list to avoid supplements with toxic chemicals, microplastics, preservatives, flavors, colors and other provably harmful ingredients.
We do the same for personal care and clean home products and so far have banned 500+ harmful ingredients from parabens, phthalates and oxybenzones – so that you know anything on the Superpower marketplace is a product you can trust.
Finally, we look at independent quality testing for purity, strength, identity, and disintegration from the most reputable sources on the internet including:
Our sourcesView our list of sources
These sources are valuable for evaluating the safety and non-toxicity of products, providing consumers with reliable information to make informed choices.
EWG is known for providing tools and resources to make better choices regarding toxic-free, safe products in various categories, including household and consumer products.
This database features over 2000 curated non-toxic products vetted by third-party unbiased organizations like Environmental Working Group, Think Dirty, MadeSafe, GreenGuard, ConsumerLab, NSF, and more.
This app allows users to check for chemicals in products by entering the product name or scanning the barcode. It provides a toxicity rating and suggests safe and cleaner alternatives.
ConsumerLab is known for its comprehensive set of test results, including dosage, phytonutrient levels, and contaminant levels in various products.
2.3 Evaluate
Manufacturing Standards & Sourcing
Manufacturing and sourcing standards are key to understanding product quality.
For supplements, we screen for designations such as CLIA, GMP, NSF, and FDA, which together help inform the quality of the manufacturing and sourcing process.
For food products, our screening extends to examining the quality of the ingredients and methods used in production, such as whether the food is grass-fed, processed vegetable oil free, and organic.
Beyond the products themselves, our holistic evaluation looks across the entire supply chain. We perform company background checks and ensure there are not concerns with products or their supply chains.
2.4 Evaluate
Price & Value
We have a deep commitment to balancing affordability with quality, and price with performance, ensuring that members receive excellent value in every product they order.
We measure product efficacy not just in numbers but also through the satisfaction of the broader customer universe, aiming for brands that have a substantial collection of genuine, positive customer reviews
2.5 Evaluate
Mission Alignment
The brand’s mission must supports or mirrors Superpower’s mission to bring preventative care to all and increase human lifespan and healthspan by preventing chronic disease through the pillars of environment, sleep, mental health, physical health, and nutrition.
