Why TikTok Is Drinking Green Water for Weight Loss

The Trend: Remember chlorophyll from science class? You know, the pigment that makes plants green? TikTok has now decided it belongs in your water bottle. Proponents are buying chlorophyllin, a water-soluble version of chlorophyll made with copper and sodium, so your body can absorb it more easily. People stir a few drops into their water and credit it with clearer skin and easier weight loss.

What People Are Saying: The research doesn’t really align with those claims. No published human study has tested whether drinking chlorophyll water clears up your skin or helps you lose weight. The relevant skin research that does exist looked at topically applied products instead of ingested ones. It’s also hard to tell whether any anecdotal weight loss comes from the drops themselves or from simply drinking more water.

What to Know: Chlorophyllin appears safe for short-term use, and the main reported side effects are an upset stomach and green poop. Staying hydrated on its own can help your skin and keep you feeling fuller, so experts suspect any glow-up likely comes from all that extra water. Want chlorophyll anyway? You get it every time you eat spinach or broccoli, along with fiber the drops can’t offer.
