Top 5 Functional Drinks for Energy, Focus, and Gut Health

Share |

“Functional” beverages are trending for a reason: they’re built to do more than quench thirst. If your goals include sharper focus, steadier energy, or a happier gut, the right drink can help.

Below are five options favoured by wellness pros and supported by research.

1) Yerba Mate

2) Apple Cider Vinegar (ACV) Tonic

Why it helps

  • Provides iron, magnesium, and B12 to support energy metabolism
  • May support detox pathways and immune function
  • High in prebiotic fiber when paired with leafy greens

How it feels: Spirulina’s flavor is bold; citrus and banana balance it nicely. A strong pick for mornings or post-workout.
