I used to buy supplements based on reviews and recommendations without really knowing whether I was getting what I paid for.

The Verifier Lab Insider programme has completely changed that.

I love being able to see independent lab results for products I actually recognise, and having a say in what gets tested next makes it even better. For £60 a year, it’s given me far more confidence about which supplements I buy and which ones I avoid

Love this concept!

I've always had doubts about Zooki Liposomal Vit C given the bad press they've had in the past re lipsomal status - however I love the flavor, and it's pretty cheap for lipsomal Vit C.

So I submitted it to the leaderboard when I joined and it endedup getting into the top 3 in 2 weeks (must have been other members wanting to see this tested too!). Results were posted on the platform the following week or so.

Skimming through some of their earlier test results on other brands was also eye-opening! I was able to warn my Mum about a product she takes regularly, that didn't have hardly any of the ingredient in it that it said it did.

Well worth it for £6.99 a month.
