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?
