Frequently Asked Questions.
How are the products selected?
Our main focus here at Healf is to make sure you are getting access to the best global wellbeing brands that align with our core values, where we believe wellbeing is characterized by The Four Pillars - EAT, MOVE, MIND, SLEEP. We hand select products all over the world and put them through our strict three step curation process which entails discovery, expert validation, and our community testing. In order to protect our community we always quality check all ingredients of the products we select, and do not feature products with any ingredients we mention on our Healf Banned Ingredient List.
Do you have resources or articles on maintaining a healthy lifestyle?
Our team of in-house experts stay up to date with the latest research on wellbeing. They constantly evaluate health trends and make sure to filter real vs. faux and deeply understand that there truly is no ‘one size fits all’ approach to your wellbeing. You can check the Healf journal here and make sure to subscribe to our mailing list for more content.
Can I find more information about the ingredients used?
We love people who check ingredients. You’ll find detailed information about the ingredients in every product page and if you find something you’d like to flag with us or have more questions, drop us a message.
Three step
curation process
The Healf stamp of approval: Here at Healf every product goes through a rigorous Three Step Curation Process, so you know you are only getting the best.
Healf's discovery process leverages a global scouting network of health professionals and AI-powered trend analysis to unearth the finest health products worldwide, ensuring you have access to a constant stream to the most innovative and highest quality products.
Every product undergoes examination by a panel of industry specialists, including dieticians, personal trainers, psychologists, and sleep experts, reviewing each item to ensure it meets our rigorous standards for health.
Our community stands at the backbone of our business. We have a group of customers that rigorously test and review each product for its real impact on well-being; if it doesn't make a noticeable difference for most, it won't make our website.
