CARB COUNTS BY SERVING SIZE
| Serving | Net Carbs | Total Carbs | Calories | Notes |
|---|---|---|---|---|
| 1/4 tsp (≈1g) | ~0g | ~0.8g | ~3 | Often enough to thicken a smoothie or stabilize a cold sauce. |
| 1/2 tsp (≈2g) | ~0g | ~1.5g | ~7 | Good starting point; increases thickness quickly. |
| 1 tsp (≈3g) | ~0g | ~2.3g | ~10 | For thicker cold recipes; may be too much for sensitive stomachs. |
| 1 Tbsp (≈9g) | ~0g | ~7.0g | ~30 | Very large amount—more likely to cause GI and texture issues. |
WHY IT'S KETO-FRIENDLY
- Net carbs are effectively zero because the carbs are fiber
- Thickens without cornstarch or flour—useful for low-carb cooking
- Works especially well in cold recipes where you want creamy texture
- Used in tiny amounts, so it’s easy to fit into keto macros
- Can improve texture in keto ice cream and shakes
HOW TO USE IT ON KETO
- Use a tiny amount—start with 1/8 tsp and increase if needed.
- Blend it in to avoid clumps; guar gum can clump when added all at once.
- Great for cold recipes: smoothies, keto ice cream, and chilled sauces.
- For hot sauces and gravies, some people prefer Xanthan Gum—test both.
- If you get GI symptoms, reduce the dose or switch to Gelatin (Unflavored)/Psyllium Husk.
PREPARATION SUGGESTIONS
THICKER SMOOTHIE
Add a pinch of guar gum while blending a smoothie for a thicker, milkshake-like texture.
KETO ICE CREAM
Use a very small amount in homemade ice cream bases to reduce iciness and improve scoopability.
COLD KETO SAUCE
Whisk into yogurt-based sauces or dips for a thicker consistency without added starch.
PROTEIN SHAKE UPGRADE
Blend a Protein Shake with ice and a pinch of guar gum for a creamier texture.
CHILLED CHOCOLATE PUDDING
Combine cocoa, sweetener, milk/cream, and a tiny amount of guar gum; chill until thick.

What can I use instead of guar gum on keto?
Depending on the recipe: Xanthan Gum, Gelatin (Unflavored), Psyllium Husk, or chia seeds. Avoid cornstarch if you’re strict keto.
