WHY IT'S KETO-FRIENDLY

  • Essentially zero net carbs; sweetened versions use non-nutritive sweeteners
  • Tea polyphenols remain from the brewing process
  • Caffeine and/or L-theanine can support alertness without carbs
  • Cold, hydrating option that replaces sugar-laden beverages
  • Easy to batch-brew for convenient, on-hand drinks
  • Generally minimal impact on blood sugar or ketosis when unsweetened

HEALTH BENEFITS

  • Rich in tea antioxidants (catechins/theaflavins) that may support metabolic health
  • Caffeine + L-theanine combo can aid focus and mood
  • Hydration without caloric or carb load
  • May support heart health markers when part of a balanced diet
  • Unsweetened versions avoid glucose/insulin spikes
  • A superior alternative to regular sweetened iced tea

PREPARATION SUGGESTIONS

FRESH BREWED

Brew strong black or green tea, chill, and sweeten to taste with stevia or allulose—or enjoy unsweetened for a clean zero-carb option.

LEMON LIFT

Add a squeeze of fresh lemon or a slice of lime for brightness and a little vitamin C without meaningful carbs.

HERBAL COOL

Cold-steep with peppermint tea bags for a naturally cooling, caffeine-optional twist.

OVER ICE

Serve over plenty of ice with a lemon wheel; keep garnishes keto-friendly (citrus peel, herbs).

AFTERNOON FOCUS

Use a mid-afternoon glass for gentle alertness; choose decaf if you’re caffeine-sensitive.

KETO COCKTAIL

Combine with vodka, rum, or whiskey and a splash of diet lemonade for a low-carb highball.
