Why Celark?
We ask lots of difficult questions and tell you the truth.
Just like you, we want to know exactly what’s in every ingredient we use. It takes us forever to launch new products because we spend so much time annoying our suppliers. We share all of this information with you, so you can decide.
We’re the David of the Goliath supplement industry.
You’re the most important person at the end of the day.
What customers say

IFOS Certified again and again
And again. Every single batch of our omega-3 supplements is tested by the International Fish Oil Standards – the most rigorous benchmark for purity and freshness. And that’s on top of the two rounds of tests we do ourselves because we’re perfectionists. A good thing to be in this business. You’ll find all the results on our product pages.

Doom scrolling symptoms? Stop here.
Researching supplement, let alone your symptoms, is overwhelming and confusing. Why can’t the label just say x cures y? Legislation is why (some of it fair, some of it bizarre and loaded in favour of big pharma). So we’ve curated advice and insights on our constantly updating expert hub, plus real-life stories and gnarly conversations about our complex bodies, minds and health on our blog, The Supplement.
