Garlic may be small, but it is surprisingly dense in nutrients. This calculator converts any amount of raw garlic into calories, protein, carbohydrates, fiber, sugar, fat, and several key micronutrients using USDA reference data. It is designed for anyone tracking macros, following a lower-carb or keto eating pattern, or simply curious about what a few cloves add to a meal.
Start by entering an amount and choosing a unit — grams, ounces, whole cloves, or teaspoons of minced garlic. The preset chips give you one clove, two cloves, 10 g, 50 g, or 100 g instantly. Optional checkboxes add micronutrient values and show each nutrient as a percentage of the Daily Value, which is useful for diet planning and comparing foods.
The tool models fresh, raw garlic only. Garlic powder, cooked garlic, and jarred minced garlic have different water contents and nutrient densities, so use those product labels if you need a precise count.
🧄 Garlic Nutrition Calculator
Estimate calories, macros, and micronutrients for fresh raw garlic.
Quick Start
This calculator turns any serving size of raw garlic into practical nutrition numbers. It is handy when you are logging a meal, scaling a recipe, or checking whether your stir-fry adds meaningful amounts of vitamin C or manganese. The workflow takes only a few seconds.
- Enter the amount you plan to eat in the number field, then choose a unit: grams, ounces, whole cloves, or teaspoons of minced garlic.
- Use the preset chips to quickly set a common serving such as one clove, two cloves, 10 g, 50 g, or 100 g.
- Keep the micronutrients checkbox on to see vitamin C, calcium, iron, potassium, manganese, and sodium.
- Turn on Show % Daily Value if you want each micronutrient expressed against a 2,000-calorie reference diet.
- Press Calculate Nutrition. The result card updates instantly with calories, macros, net carbs, and optional micronutrients.
All values are for fresh raw garlic with the papery skin removed. If you weigh a full bulb, subtract the skin and base before logging.
Nutrition Data & Formula Explained
The calculator uses the raw garlic profile published in USDA FoodData Central. Raw garlic is unusually nutrient-dense by weight because cloves contain less water than many other vegetables. The scaling formula is straightforward:
(nutrient per 100 g × grams in your serving) ÷ 100
For whole cloves, the calculator assumes 4 g per average raw clove. For teaspoons of minced garlic, it assumes 2.8 g. Clove size varies widely — some peeled cloves weigh 6 to 8 g — so for precise logging, use the gram option with a kitchen scale.

Worked Examples
Example 1: one average clove (4 g)
Calories: (149 × 4) ÷ 100 = 5.96 kcal
Total carbs: 1.32 g; net carbs: 1.24 g; protein: 0.25 g; vitamin C: 1.25 mg.
Example 2: 28 g (about 1 oz, or 7 small cloves)
Calories: 41.7 kcal
Protein: 1.78 g; carbs: 9.26 g; fiber: 0.59 g; net carbs: 8.67 g; potassium: 112 mg.
Example 3: 100 g (about 25 average cloves)
Calories: 149 kcal
Protein: 6.36 g; carbs: 33.06 g; fiber: 2.1 g; vitamin C: 31.2 mg; manganese: 1.67 mg (about 73% DV).
Tips, Accuracy & Common Mistakes
- Use raw garlic, not cooked. Cooking evaporates water, so 100 g of cooked garlic has a different per-gram nutrient density than 100 g of raw cloves.
- Garlic powder, jarred minced garlic, and garlic salt are not the same as fresh cloves. This calculator applies only to fresh raw garlic.
- Weigh the edible portion. A full bulb includes dry skin, which should not be counted. For whole cloves, use the clove unit only for rough estimates.
- For keto and low-carb users, focus on net carbs. Garlic is low-carb only because servings are small; 100 g has about 33 g of total carbs.
- Health compounds such as allicin do not contribute calories or macros. This tool reports measurable nutrients, not phytochemical content.
- Daily Value percentages are based on FDA reference values for adults eating a 2,000-calorie diet. Your individual targets may be higher or lower.

Frequently Asked Questions
Is garlic keto-friendly? A single average clove contains about 1.3 g of total carbs and 1.2 g of net carbs. Used as a seasoning, garlic fits easily into most keto and low-carb plans. The real carb load usually comes from the sauces or sides around it, not from the garlic itself.
Does cooking garlic change its nutrition? Calories and carbohydrates remain broadly similar once water loss is accounted for, but vitamin C degrades with heat and some sulfur compounds change. This calculator models raw garlic only.
Can I use this calculator for garlic powder? No. Garlic powder is concentrated, has much less water, and supplies roughly 330 kcal per 100 g. Check the label on your spice jar for accurate values.
Why is manganese so high in garlic? Garlic is one of the richest common seasoning sources of manganese. A 100 g serving provides more than 70% of the daily value, though a typical clove supplies only about 1.7 mg.
Should I count the weight of a whole bulb? No. A typical bulb includes dry skin and sometimes a stem. Weigh just the peeled cloves you actually eat.
