Why We Built This

The functional beverage space is exploding — and it's full of noise. Marketing claims, influencer partnerships, and underdosed products make it nearly impossible to know what actually works. We built The Functional Sip to cut through all of it.

Our Review Process

Every product we review is purchased or received for testing. We evaluate each drink across five dimensions: taste, effects, ingredient quality, value for money, and how it compares to alternatives in its category. Our scores are final and never adjusted based on brand relationships or affiliate arrangements.

We buy or independently receive all products
Scores are never influenced by affiliate deals
We disclose all affiliate relationships clearly
We update reviews when formulations change
We cover the full range — not just premium brands
We test effects over multiple sessions, not just once
