The science of health demands a new standard

With more health products than ever before, it has never been harder to know what information to trust, which products to choose, and what solutions you really need.

Our mission is to change this by creating the most trusted place to discover curated, quality-assessed health & wellness products from around the world.

Scientific rigor is our guiding principle. Before it goes in your body, it goes through us.

How our curation process works

2

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.

Systematic Reviews & Meta-analysis Randomized Controlled Double Blind Studies Cohort Studies Case Series Case Reports Ideas, Editorials, Opinions Animal Research In Vitro (test tube) Research
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.

500+

Banned 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:

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.

3

Monitor

Once a product is accepted into the Superpower marketplace, it's not the end of our due diligence.

We reassess products every six months to ensure continued compliance with our brand standards and the latest research.

Ensuring lifelong quality through regular monitoring and re-evaluation.

About Infrared Black Sauna

Benefits

  • Boosts Metabolism: Far Infrared Energy pulsates the water molecules in the body, and breaks down the water molecule clusters. This improves capillary function, allowing the water molecules to easily enter, revitalize, and regenerate the body's cells.
  • Burns Calories: The RELAX Far Infrared Sauna can product 2 to 3 times the sweat of other FIR Saunas. Using the Relax sauna for 15 minutes could easily burn about 600 calories, the equivalent of running 4-6 miles, or doing a 45 minute cardiovascular workout.
  • Reverses the Aging Process: Americans are used to sitting for extended periods, often over-eat, usually do not exercise regularly, and are often susceptible to chronic diseases and aging. The FIR Sauna can raise the metabolic rate, enhance beauty, and reverse the aging process.
  • Enhances Detoxification: The Relax FIR Sauna can open up the pores in the body and release the toxins hat are building up inside. It can clean up the body and reduce the workload of the body in removing toxins.

Suggested Use

Experience rejuvenating heat therapy with the "Black" Relax Sauna by simply setting it up in your preferred space. Sit comfortably in the included chair, set the reflective silver interior aglow, and enjoy a 17-minute session, efficiently promoting relaxation and muscle recovery. Compact and stylish, this portable sauna offers a convenient and effective way to incorporate heat therapy into your daily routine.

Supporting Research

Does the Relax Sauna have harmful EMFs?

Relax Sauna is one of the few companies which has done certified, independent testing on their sauna and publicly published the results.



In the test, the maximum level of EMF recorded was 46.510 mG at 2 centimeters from the heater, which is much closer than your body is during use. The American Conference of Governmental Industrial Hygienists (ACGIH) standards for occupational exposure to EMF is 10,000 mG(milligauss). Most saunas use large panels to generate the infrared. These panels have many wires of electric current and surround the body, thus creating a magnetic field around the body. Relax Saunas have two far infrared radiators down below the feet. The electric current does not go near the body and thus EMF levels are low near the body and head when using. Harmful levels of EMF are generally only seen near power lines and industrial equipment which uses far more power than a home device.

How do I clean the sauna?

Maintenance is easy.

  • Always use a towel to cover any area your body touches to soak up sweat.
  • Use a slightly damp cloth and mild soap to wipe the interior of the sauna.
  • The foot pad between the two radiators can be removed and washed if necessary.
  • You can also let the sauna run for 5 minutes empty to "self-clean".
  • If dust builds up inside the radiator, you can use a vacuum cleaner to remove any dust.
