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

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.

500+

Banned ingredients

View list

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

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

About Vitamin C

Benefits
  • Immune Support Staple: A quintessential vitamin for immune and detox support. Our liposomal delivery bypasses the typical absorption constraints in the gut, delivering this nutrient directly to the cells for rapid uptake.
  • Unsurpassed Absorption: Vitamin C capsules often have poor bioavailability that limits absorption and the benefits. Liposomal technology delivers more to the cells to support immunity, collagen production, and antioxidant protection.
  • Buffered + Non-GMO: Buffered vitamin C is generally better tolerated by those with gastrointestinal sensitivity.† This product is tested Non-GMO.
  • Not All Liposomal C Formulas are Equal: Beware of opaque, large particle ‘liposomal’ vitamin C formulas. Our exclusive technology and ‘clear’ formulations enhance cellular access with smaller liposomes for more efficient delivery.

Suggested Use

Take 1 teaspoon by mouth. Hold in mouth 30 seconds before swallowing. Repeat to the desired dosage or as directed by a healthcare professional. Take an empty stomach, at least 10 minutes before meals. If pregnant, breastfeeding, or planning to become pregnant, consult your physician before use. Use within 60 days of opening.
