Although caviar isn't a typical everyday meal, it's considered a luxurious seafood delicacy. We'll go through the nutritional values and essential micronutrients of caviar.

What is Caviar?

Caviar is the roe or eggs of various species of sturgeon fish. Osetra, Beluga, Kaluga, Sevruga, and Sterlet are the most common species. Although female fish lay eggs, only sturgeon eggs are considered caviar. Other fish eggs, such as salmon, trout, and flying fish, are known as "roe": they are a popular and less expensive alternative to caviar. 

In this article, we will solely focus on the nutritional composition of caviar. To learn more about the history of caviar, its varieties, as well as the proper way to prepare, eat, and store it, check out our article on the topic – Caviar: Varieties, Consumption, Storage, and Taste


This section of the article will discuss uses in different diets and nutrition of black and red granular caviar (vitamins, minerals, micronutrients).

Caviar has a rich nutritional profile, even if consumed in small amounts.

The serving size is usually one tablespoon or approximately 16 grams.

Caviar consists of 48% water, 25% protein, and 18% fats, as depicted in the macronutrient composition chart below.

100g of caviar provides 264 calories, and one average serving (16g) of caviar provides only 42 calories.

Hence, caviar contains moderate to low calories. Since caviar is packed with rich nutrients, it is a great choice for weight loss diets. Learn more about how caviar fits into popular weight loss diets in our article. 


Caviar contains only a few grams of carbs4g per 100-gram serving, and all the carbs are net carbs. To learn more about how caviar fits into the keto diet, check our article – Caviar and Keto Diet - Is It Keto-Friendly.     


Proteins are responsible for nutrient processing, aiding in the proper movement of body parts, providing immune protection, and assisting in the regulation of hormone synthesis.

Caviar is rich in high-quality protein. It provides 4g of protein per serving and 24.6 g per 100g accordingly.

Caviar falls in the range of the top 13% of foods as a source of protein.

Caviar is relatively high in all 9 essential amino acids – tryptophan, threonine, isoleucine, phenylalanine, valine, histidine, lysine, leucine, and methionine. It also contains other amino acids, such as arginine, cystine, tyrosine, glutamic acid, serine, alanine, glycine, proline, and aspartic acid. 

Caviar also contains a high concentration of protein fractions such as vitellin and phosvitin. Small proteins, possibly lysozyme or phosvitin, are also present in salmon roe.

Caviar has a high amount of good fats. It falls in the range of the top 18% of foods as a source of fats, containing 25.6g per 100g; this is two times higher than the fat content of broccoli.

Of these fats, 4.06g is saturated, 4.6g is monounsaturated, and 7.4g is polyunsaturated.

Moreover, caviar is rich in omega-3 fatty acids along with large amounts of eicosapentaenoic acid and docosahexaenoic acid, which can help to support the nervous system, immune system, and circulatory system health.

Caviar contains no trans fats.

Caviar contains a high level of cholesterol. It falls in the range of the top 5% of foods as a source of cholesterol.

One serving of caviar can cover 30% of your daily cholesterol need.

There are two types of cholesterol: high-density lipoproteins (HDL) and low-density lipoproteins (LDL). HDL is considered to be healthy, whereas LDL is considered to be unhealthy. Caviars’ cholesterol is LDL, but the omega-3 fatty acids can significantly reduce triglycerides and raise HDL levels – “the good” cholesterol. Please also note if you have any cardiovascular issues, it is recommended to consume caviar in moderation to control the cholesterol intake.

Organic Acids

Caviar contains high concentrations of organic acids such as citric, lactic, and acetic acids. Organic acids can stimulate pancreatic enzyme secretion, reduce gastric pH, inhibit pathogens, and serve as an energy source during GI-tract intermediary metabolism (1).


Caviar is an excellent source of vitamins, especially B-complex vitamins and Vitamin D. Pyridoxine (B6), riboflavin (B2), cyanocobalamin (B12), and pantothenic acid (B5) are the predominant vitamins in caviar.

All B-complex vitamins aid the body's energy production by converting carbohydrates into glucose.

Caviar falls in the top 14% of foods as a source of Vitamin B12. 

One serving of caviar (16 grams) packs more than double your daily requirement of Vitamin B12.

One serving of caviar can also cover 20% of your daily Vitamin B5 need. Caviar is an excellent source of Vitamin B2, providing about 0.62mg per 100 g. It falls in the range of the top 13% of foods as a source of Vitamin B2.

Caviar also provides Vitamin A, Vitamin E, Vitamin B1 (Thiamine), and folate in moderate amounts. It is lowest in Vitamin B3 (niacin) and Vitamin C, and it completely lacks Vitamin C.

Caviar has a rich mineral profile. It contains high amounts of magnesium (300mg per 100g), phosphorus (275mg per 100g), calcium (275mg per 100g), selenium (65.5µg), iron (11.88mg per 100g), and choline (491mg per 100g).

Caviar falls in the range of the top 5% and 9% of foods as a source of iron, magnesium, and calcium.

Caviar contains 2.2 times more calcium than milk and 4.6 times more iron than beef per 100-gram serving, although caviar is usually consumed in smaller amounts.

One serving of caviar can cover 30% of your daily iron need.

Caviar also provides moderate amounts of manganese and copper.

It is important to note that caviar contains high amounts of sodium, more than 97% of foods. One serving (16 grams) of caviar contains 240mg of sodium. Too much sodium intake can cause stroke, heart failure, osteoporosis, stomach cancer, and kidney disease. So, it is better to consume caviar in moderation.

Glycemic Index

Based on the low level of carbohydrates, caviar can be considered a 0 glycemic index. You can also visit our Glycemic index chart page for glycemic index values of 600+ pages.


Caviars are acidic. The pH value of caviar falls in the range of 4.8 to 5. The acidity of caviar can also be measured by looking at its potential renal acid load or PRAL value. Caviar has a PRAL value of 10.1, making it an acid-producing food.

Purines in Caviar

Purines are natural substances that, when metabolized, form uric acids. Eating foods high in purines may cause uric acid to accumulate in the body, putting the individual at risk for various illnesses, including gout

Kaneko et al. determined that caviar contains 94.7 mg of purines per 100-gram serving, classifying it within the low to moderate range of purine content (2).

Wild-Caught vs. Farmed Sturgeon Caviar: A Nutritional Comparison

In a study by Wirth et al., the authors compared the nutritional compositions of caviar sourced from 22 wald-caught and 2 farmed sturgeon specimens (3). The authors found that caviar obtained from farmed sturgeon had lower protein and lipid levels than caviar obtained from wild-caught surgeons. 

Caviar samples from farmed sturgeons also had higher levels of linoleic acid and lower levels of arachidonic acid; however, the proportion of n-3/n-6 PUFAs (polyunsaturated fatty acids) was similar in wild-caught and farmed sturgeon caviar. Moreover, one of the samples from the farmed sturgeons was found to have the lowest concentration of DDT

A different study found that although differences existed between the caviar sourced from farmed and wild-caught sturgeons, they did not significantly impact the overall quality of the caviar (4). The authors concluded that caviar from farmed sturgeon may be a more sustainable source

Comparison to Similar Foods

We compared caviar to other foods in our database and highlighted which one contains more macronutrients.

Compared with roe, caviar is higher in Vitamin B12, iron, magnesium, Vitamin B5, selenium, and calcium.

When it comes to truffles, caviar provides more iron, Vitamin B5, magnesium, and selenium.

Health checks

Low in Cholesterol
limit break
 ⓘ Dietary cholesterol is not associated with an increased risk of coronary heart disease in healthy individuals. However, dietary cholesterol is common in foods that are high in harmful saturated fats.
No Trans Fats
 ⓘ Trans fat consumption increases the risk of cardiovascular disease and mortality by negatively affecting blood lipid levels.
Low in Saturated Fats
 ⓘ Saturated fat intake can raise total cholesterol and LDL (low-density lipoprotein) levels, leading to an increased risk of atherosclerosis. Dietary guidelines recommend limiting saturated fats to under 10% of calories a day.
Low in Sodium
limit break
 ⓘ Increased sodium consumption leads to elevated blood pressure.
Low in Sugars
 ⓘ While the consumption of moderate amounts of added sugars is not detrimental to health, an excessive intake can increase the risk of obesity, and therefore, diabetes.
