WHY IT'S KETO-FRIENDLY

  • No net carbs: absorbed but minimally metabolized, so it doesn’t spike glucose/insulin
  • Sugar-like function and texture: excellent 1:1-ish swap in many recipes
  • Very low calorie (~0.4 kcal/g) supports weight management
  • No impact on ketosis when used in reasonable amounts

HEALTH BENEFITS

  • Does not raise blood glucose or insulin—helps maintain ketosis
  • May modestly aid insulin sensitivity and post-meal glucose control
  • Low-calorie sugar alternative that can reduce overall sugar intake
  • Often well tolerated in small–moderate amounts

PREPARATION SUGGESTIONS

KETO BAKING SUBSTITUTE

Use as a near 1:1 sugar replacement in cakes, cookies, and muffins; it browns and caramelizes similarly.

SWEETEN BEVERAGES

Dissolves in hot or cold drinks—perfect for black-coffee or green-tea.

SAUCES AND SYRUPS

Simmer with water (and a pinch of xanthan gum if desired) for glossy, sugar-free syrups and glazes.

HOMEMADE ICE CREAM

Prevents iciness and keeps keto ice cream scoopable compared with many other sweeteners.
