How Many Calories in Sriracha? Nutrition Facts & Macros

Sriracha contains 93 kcal per 100 g, but you rarely eat that much at once. One teaspoon (5 g) has only about 5 kcal, and one tablespoon (15 g) has about 14 kcal. The calories come mainly from sugar (15.1 g per 100 g) and a small amount of carbs from the peppers. Even generous use — 2-3 teaspoons per meal — adds only 10-15 kcal, making it one of the most calorie-efficient flavor boosters available.

Sriracha contains 15.1 g of sugar per 100 g — that sounds like a lot, but in a teaspoon (5 g) it is only 0.75 g of sugar. One tablespoon (15 g) has about 2.3 g. Sugar is the third ingredient and gives sriracha its characteristic sweet-heat balance. Compared to ketchup (21.27 g sugar per 100 g), sriracha has about 30% less sugar, and you typically use much less of it per serving.

In typical portions, sriracha is essentially neutral — 5 kcal per teaspoon with negligible macros. The capsaicin from red jalapenos has been linked to mild thermogenic effects, reduced appetite, and anti-inflammatory properties in research. Sriracha also provides 26.9 mg of vitamin C per 100 g. The main concern is sodium — 2120 mg per 100 g, though one teaspoon delivers about 106 mg (5% of the daily limit). As a flavor enhancer that adds nearly zero calories, it is a smart swap for higher-calorie sauces.

Yes, in moderation. Sriracha has 17 g net carbs per 100 g (19.2 g carbs minus 2.2 g fiber), but one teaspoon (5 g) has only 0.85 g net carbs — perfectly acceptable on keto. One tablespoon (15 g) has about 2.55 g net carbs, which is still manageable. For strict keto, limit to 1-2 teaspoons per meal. If you want a zero-carb alternative, Tabasco or other vinegar-based hot sauces have essentially 0 g carbs.

Sriracha has 93 kcal per 100 g while Tabasco has about 12 kcal. The biggest difference is sugar: sriracha has 15.1 g per 100 g versus virtually 0 g in Tabasco. Sriracha is thicker, sweeter, and garlicky with a slow-building heat, while Tabasco is thin, vinegary, and immediately sharp. For keto or low-carb, Tabasco is better (near-zero carbs). For flavor complexity, sriracha wins. Sodium is high in both — 2120 mg (sriracha) vs 1665 mg (Tabasco) per 100 g.

Sriracha contains 2120 mg of sodium per 100 g — one of the highest levels among common condiments. One teaspoon (5 g) has about 106 mg of sodium (5% of the 2300 mg daily limit). One tablespoon (15 g) has about 318 mg (14% of the daily limit). If you use sriracha on multiple meals per day, the sodium adds up quickly. People monitoring blood pressure should use it sparingly or look for reduced-sodium versions.
