Buying Guide

Check calorie and sugar content

Choose zero-calorie or sugar-free enhancers if you want flavor without added sugars; product labels and ingredient lists indicate sweeteners used

Compare flavor options and variety packs

Single-flavor bottles may suit a favorite taste, while variety packs provide multiple flavors for more flexibility

Look at serving size and bottle count

Consider pack sizes and stated servings per bottle to estimate how long a supply will last for your household

Note added functional ingredients

Some enhancers include caffeine or other additives—check labels if you want an energy boost or prefer no stimulants

Evaluate concentration and mixability

Denser concentrates require fewer drops per glass; check user reviews for clarity on potency and how well the flavor blends with still or sparkling water
