Tobiko (Flying Fish Roe): Nutrition, Benefits, Colors & Safety

Q: What is tobiko made of?

Tobiko is flying fish roe cured with salt.[11][12] Some versions add flavor and color, such as wasabi flavor, sorbitol, sugar and FD&C dyes, so the ingredient list tells you what you're getting.[26][27]

What tobiko is, what a tablespoon of these tiny flying fish eggs gives you, what the human research on fish roe shows, what the colors on the label mean, and who should skip it raw.

Tobiko at a glance

Tobiko is the roe of flying fish: tiny, crisp, golden-orange eggs, cured with salt and spooned over sushi. A tablespoon of fish roe has about 21 calories and 63% of the daily value for vitamin B12, plus about 0.35 grams of the omega-3s EPA and DHA.1 2

Best use: a spoonful over fish, a rice bowl or scrambled eggs
Research: in a placebo-controlled trial of 33 adults, herring roe powder raised HDL cholesterol, and in a placebo-controlled trial of 64 adults, roe-oil capsules eased psoriasis3 4
Choose: color from real ingredients such as wasabi, beet or yuzu, with no FD&C dyes or MSG-type flavor enhancers
Who should skip it: because it's eaten raw, skip it during pregnancy, for young children and with a weakened immune system5
Plan: fish-first eating in the free Anti-Inflammatory Reset

Tobiko is the roe of flying fish, the tiny orange eggs pressed onto the outside of sushi rolls and spooned over salmon nigiri. Each egg pops when you bite down, with a little crunch and a clean, salty finish.

On my show, I've pointed out that people in Japanese and other Asian food cultures ate fish roe because it was one of the most nutrient-dense, healing foods they could eat.6 In Heal Your Cells, which I wrote with Dr. Will Cole, fish roe is on our list of foods rich in phospholipids, alongside egg yolks, organ meats, salmon and full-fat fermented dairy.7

You eat tobiko by the spoonful, so it works best as an occasional, bright finish on a plate built around fish. Choose true flying fish roe colored with real food and keep it cold.

Oftentimes we see some of these foods, whether it be an organ meat or something like fish roe, and essentially it's like a vitamin. These are incredible superfoods.Dr. Josh Axe, DC, DNM, CNSFrom Cellular Health EXPERT: How to Build Bulletproof Cells for Energy, Detox & Longevity, The Dr. Josh Axe Show (2025), at 13:06

Did you know?

The name is Japanese. Tobi- comes from tobu, "to fly," as in tobiuo, flying fish, and ko means "child."9
By weight, fish roe carries more than four times the daily value of vitamin B12: 10 micrograms in 100 grams.1 2
In the ripe roe of seven North Atlantic fish, omega-3 fats often made up about half of all the fat in the eggs.10

What is tobiko?

Quick answer

Tobiko is the salt-cured roe of flying fish, a classic garnish in Japanese sushi. True tobiko comes from flying fish of the genera Cheilopogon and Hirundichthys, and its eggs are 2 millimeters across or smaller, crisp and naturally golden orange.11 9

Tobiko is cured rather than cooked. Like other roe products, the eggs are graded and sorted, then salted or brined and cured, and most are sold refrigerated or frozen.12

Flying fish roe is in short supply, so capelin roe is sometimes sold in its place.11 In a DNA survey of 61 sushi samples from 18 Italian cities, 16 of them roe, most tobiko samples were true flying fish roe, while 20% to 33% of them, depending on the region, turned out to be capelin, the fish masago comes from.11 When you buy tobiko, look for flying fish roe at the top of the ingredient list.

Tobiko nutrition facts

Quick answer

One tablespoon of fish roe (15 grams) has about 21 calories and 3.3 grams of protein, with 63% of the daily value for vitamin B12 and about 0.35 grams of the omega-3s EPA and DHA. It also gives you 11% of the daily value for selenium and 9% each for choline and vitamin D.1 2

Calculated from USDA FoodData Central FDC ID 175132, fish roe (mixed species), raw, at 15 grams; USDA has no separate record for tobiko, and its selenium and choline values are estimated from similar foods. % Daily Value uses FDA reference values.1 2

What is tobiko good for?

Quick answer

Tobiko is best for adding vitamin B12 and omega-3s carried in phospholipids to a meal in a single spoonful.1 16 In human studies of other fish roe, herring roe powder raised HDL cholesterol in a placebo-controlled trial of 33 adults, roe oil raised blood omega-3s more than fish oil over 12 hours in a trial in which 32 adults each tried both, and roe-oil capsules eased psoriasis in a placebo-controlled trial of 64 adults.3 17 4

Where the research stands

No study has fed tobiko itself to people yet; the human research on fish roe comes from herring and cod roe. It includes one whole-food trial of herring roe powder (33 adults, 8 weeks), a 16-person trial of a cod roe spread and trials of roe-oil capsules at supplement doses (21 to 64 people, 2 to 26 weeks), and all three roe-oil trials had funding or authors from a Norwegian roe-oil maker.3 18 17 19 4 Tobiko's own fats have been measured directly, and its phospholipids are especially rich in DHA.16

How tobiko works in your body

Much of tobiko's value lies in how roe packages its omega-3s: inside phospholipids, the fats your cell membranes are built from.7 This is how those fats travel from the spoon to your cells:

1Packed in phospholipids

In roe from herring, cod and three other North Atlantic fish, phospholipids make up 62% to 77% of the fat, and in a Japanese analysis, tobiko's phospholipids carried a higher share of DHA than those of salmon, pollock or herring roe.10 16

2Absorbed in phospholipid form

In rats, roe phospholipid and fish oil delivered similar total DHA, but more of the roe's DHA arrived in phospholipid form in the lymph, the route fats take from the gut.22

3Into your blood

In a trial in which 32 adults each tried both, herring roe oil raised blood EPA and DHA more over 12 hours than fish oil.17

4Across to the brain

Your brain can't make its own DHA; in mice, a transporter called Mfsd2a carries it across the blood-brain barrier in a phospholipid-derived form.21

5Built into every cell

On my show, I've described how EPA and DHA get built into the wall of every cell, so when inflammation starts, your body converts them into resolvins, molecules whose whole job is to actively end it and clean up the damage.23

Tobiko benefits, ranked by evidence

In order of how strong the research is, tobiko and other fish roe are best for vitamin B12 and other hard-to-get nutrients, omega-3s your body takes up readily, higher HDL cholesterol, psoriasis and inflammation support, and DHA for your brain.

Vitamin B12, selenium and choline in a spoonful

Strong evidenceComposition · USDA FoodData Central

One tablespoon of fish roe covers nearly two-thirds of a day's vitamin B12, with selenium, choline and vitamin D alongside, as the nutrition table above shows.1 2 See the top vitamin B12 foods for more ways to cover your B12.

Omega-3s your body takes up readily

Moderate evidenceHuman studyRandomized trial, each person tried both · 32 adults; randomized trial of two roe spreads, no roe-free group · 16 adults

A tablespoon of fish roe carries about 0.35 grams of EPA and DHA, and in roe, much of it comes packed in phospholipids, as the diagram above shows.1 10 Roe eaten as food raises these fats in your blood: in a Swedish trial that randomly assigned 16 adults to an ordinary or a fish-oil-enriched cod roe spread, with no roe-free group, the 8 who ate 25 grams of the ordinary spread every day for 3 weeks raised their blood EPA 51% and DHA 24%, while a marker of oxidative damage to fats rose 26% in that group.18

In a randomized U.S. trial of 32 adults with mildly high triglycerides, each person took herring roe oil for 2 weeks and ordinary fish oil for 2 weeks, at similar doses. Over the first 12 hours, roe oil raised EPA and DHA in the blood significantly more than fish oil did, and after 2 weeks, the two oils had raised them equally, roughly threefold.17

Study takeaway: phospholipid-rich roe oil raised blood omega-3s more than fish oil over the first 12 hours.

Higher HDL and healthier blood fats

Emerging evidenceHuman studyRandomized placebo-controlled trial · 33 adults; pilot with no comparison group · 21 adults

In a randomized Japanese trial of 33 adults aged 40 to 67, neither the people nor the researchers knew who got what. Seventeen ate 15 grams of freeze-dried herring roe powder a day, supplying 540 milligrams of DHA and 300 of EPA, and 16 ate a rice-powder placebo for 8 weeks. HDL cholesterol rose 4.41 mg/dL on the roe and fell 1.38 mg/dL on placebo, and free fatty acids in the blood fell on the roe while they held steady on placebo. LDL and triglycerides didn't differ between the groups, and total cholesterol rose 4.65 mg/dL on the roe, about the size of its HDL gain, and fell 9.44 mg/dL on placebo.3

In a 2-week pilot with no comparison group, 21 young adults taking capsules of herring roe phospholipids blended with fish oil (1,738 mg of DHA and 616 mg of EPA a day) lowered their triglycerides 21% and raised HDL 5.5%, and their blood sugar ran lower during a glucose tolerance test; most of the changes faded within 4 weeks of stopping.19 Seafood as a whole has a long record, and the American Heart Association recommends 1 to 2 seafood meals a week to lower the risk of heart failure, coronary heart disease, ischemic stroke and sudden cardiac death.24

Study takeaway: herring roe powder raised HDL cholesterol compared with placebo in 8 weeks.

Psoriasis and inflammation support

Emerging evidenceHuman studyRandomized placebo-controlled trial of roe-oil capsules · 64 adults, 61 finished

In a randomized Norwegian trial of 64 adults with mild-to-moderate psoriasis, neither the people nor the researchers knew who got what. Half took 10 capsules a day of herring roe oil, supplying 2.6 grams of EPA and DHA, and half took capsules of MCT oil, a coconut-oil fraction, for 26 weeks. Three people on roe oil stopped early, one of them because of gastritis. The psoriasis severity score (PASI) fell 1.8 points on roe oil and 0.6 points on placebo, and after adjusting for starting scores, roe oil came out 1.1 points ahead. In the 31 people whose scores started above 5.5, the gap was 2.4 points.4

On roe oil, 6 of the 16 inflammatory cytokines measured, including IL-6, fell significantly from where they started by week 26, though those changes and blood CRP didn't differ from placebo.4 A later analysis of the same trial found lower inflammation scores, calculated from routine blood counts, on roe oil at 26 weeks.25 The anti-inflammatory foods guide has more ways to cool inflammation with food.

Study takeaway: roe-oil capsules lowered psoriasis scores more than placebo over 26 weeks.

DHA for your brain

Preclinical evidenceAnimal studyRat and mouse studies

DHA reaches your brain through the Mfsd2a transporter in the diagram above.21 In rats, 4 weeks of DHA from roe phospholipid or from fish oil raised brain DHA equally, and when researchers tracked labeled DHA, the DHA eaten as a phospholipid put more of the label into the brain than the same DHA eaten as a triglyceride, the form in fish oil.20 See the brain foods guide for more ways to feed your brain.

Study takeaway: in rats, DHA eaten as a phospholipid carried more labeled DHA into the brain.

What do the tobiko colors mean?

Quick answer

Tobiko's natural color is golden orange; red, green, yellow and black tobiko get their color from something added.11 The color can come from a real ingredient or from FD&C dyes, and three U.S. tobiko labels in USDA's food database (black, green and wasabi) all name FD&C dyes, so the ingredient list tells you which kind you have.14 26 27

Color	Choose	Skip
Orange	The natural color of flying fish roe11	Added dyes
Red	Color from beet juice	Red 40
Green ("wasabi")	Real wasabi in the ingredients	Yellow 5 and Blue 1 with "wasabi flavor"27 26
Yellow ("yuzu")	Real yuzu	Yellow 5 and 6
Black	Orange, or a color from real food	Squid ink, and Red 40, Blue 1, Yellow 5 and 614

Put a package back on the shelf when it lists flavor enhancers or artificial colors, and tobiko is no exception.15 Blue 1, Red 40, and Yellow 5 and 6 are among the dyes I've flagged as linked to hyperactivity and behavioral problems in kids.28 Check where a "wasabi" tobiko gets its color, too. One U.S. wasabi tobiko is colored with FD&C Yellow 5 and Blue 1, flavored with wasabi flavor and blended with herring roe.27

Flavor enhancers turn up on roe labels too. One masago label lists MSG, another lists hydrolyzed soy protein,29 30 and free glutamate also hides under names like yeast extract and hydrolyzed protein, so read the whole ingredient list.15 Cleaner labels exist, too. One masago is colored only with annatto, a natural color from a seed.31

Skip black tobiko colored with squid ink, because squid doesn't have both fins and scales.28 Black color can also come from dyes, as on one U.S. black tobiko label that lists Red 40, Blue 1, and Yellow 5 and 6.14 Either way, choose another color.

Before you buy tobiko, check the label for these:

Flying fish roe first. Capelin roe at the top of the list means you're buying masago.
Color from food. Look for wasabi, beet juice, yuzu or annatto, and put back anything with FD&C dyes.
No flavor enhancers. Skip MSG, hydrolyzed protein and yeast extract.
No squid ink or crab extract. Neither comes from a fish with fins and scales.
Kept cold. Buy it frozen or refrigerated and follow the package date.

Tobiko vs. masago vs. ikura: what's the difference?

Tobiko, masago and ikura come from flying fish, capelin and salmon, and all three fish are on the Orthodox Union's kosher fish list, which covers fish with fins and scales.32 That's the standard I follow from The Biblio Diet, which calls for wild, ocean-caught fish with fins and scales.28 It goes back to Leviticus: "These shall ye eat of all that are in the waters: whatsoever hath fins and scales in the waters, in the seas, and in the rivers, them shall ye eat" (Leviticus 11:9).33

Roe	Fish	What's known about its fat	What U.S. labels show
Tobiko	Flying fish (Cheilopogon, Hirundichthys)11	Its phospholipids carried the highest DHA share of four Japanese roe products tested16	Roe and salt, often with added color or flavor, from wasabi flavor to FD&C dyes14 26 27
Masago	Capelin11	About half of capelin roe's fat is neutral fat rather than phospholipid10	Sugar on all three labels checked; dyes and MSG or hydrolyzed soy protein on two, crab extract on one, annatto on the third29 30 31
Ikura	Salmon	The richest in total fat, cholesterol and phospholipid of four Japanese roe products tested16	One label lists only salmon roe and salt34

Some masago is flavored with crab extract, and crab is a shellfish, so that masago doesn't meet the fins-and-scales standard.30 Whichever roe you choose, the same label rules apply: color from real food, and no dyes or flavor enhancers. For the full picture on fish, see the best fish to eat and the biblical diet.

How to eat tobiko

Tobiko is a finishing touch, so add it cold, right before you serve, a tablespoon or two at a time. The Dietary Guidelines, as FDA and EPA's fish advice lays out, call for at least 8 ounces of seafood a week for adults eating about 2,000 calories a day, and 8 to 12 ounces from lower-mercury choices during pregnancy and breastfeeding.35

My own body responds very well to wild-caught salmon; I could eat it three times a day. Fish oil capsules never worked as well for me, though I still think they're very helpful.23

Top a salmon rice bowl with a spoonful of orange tobiko, sliced avocado and cucumber.

Finish scrambled eggs by folding a teaspoon of tobiko into soft-scrambled pasture-raised eggs off the heat.

Spoon it onto cucumber rounds with a little mashed avocado for a quick bite.

Garnish baked salmon just before serving, for color and a little crunch.

Stir it into a seaweed salad with sesame seeds and a splash of rice vinegar.

Crown a sushi bowl, like this smoked salmon sushi bowl, with a spoonful on top.

Not sure how tobiko fits your week?

Ask Dr. Axe AI. Answers are grounded in this library, with sources shown.

Is tobiko safe to eat raw?

Quick answer

Yes, for most healthy adults, tobiko is a safe food to enjoy in small amounts, straight from the refrigerator. Skip raw roe, tobiko included, if you're pregnant, for young children and with a weakened immune system, which FDA notes is more common as people age; FDA advises those groups to avoid raw fish such as the kind found in sushi.5 36

Raw roe and who should skip it

Because tobiko is eaten raw, it carries the same caution as other raw seafood.37 5 Raw and smoked fish have been linked to listeriosis, which in pregnancy can lead to miscarriage or stillbirth, and FDA counts pregnant women, adults over 65 and people with weakened immune systems as high-risk groups.36 In Japanese retail testing, Listeria turned up in 5.7% to 12.1% of minced tuna and fish roe products, and in salmon roe kept at 50°F, it multiplied quickly within 2 days.38 Keep tobiko in the refrigerator or freezer, and put it back in the cold soon after you serve it.

FDA's Food Code requires fish served raw to be frozen first to kill parasites, which can sit deep in fish muscle, but it exempts fish eggs that have been removed from the skein, the tissue that holds the egg mass, and rinsed, because the parasite hazard isn't considered reasonably likely in them.39 The raw fish served alongside tobiko is a different matter. On my show, I've warned that sushi-grade fish often still carries parasites.40

Fish and roe allergy

Fish is one of the nine major food allergens under U.S. law, so if you're allergic to fish, skip tobiko.41 Roe can cause reactions on its own, too. In two documented cases in Finland, people reacted to roe, one of them with anaphylaxis, while eating fish without trouble.42 If you've ever reacted to fish or roe, don't assume another kind of roe is safe for you, and with a shellfish allergy, skip any masago that lists crab extract.30 Swelling of the lips or throat, wheezing or trouble breathing after eating roe needs emergency care right away: call 911. See food allergy symptoms for the other warning signs.

The bottom line

Should you eat tobiko?

Yes, as an occasional spoonful. Tobiko is the roe of flying fish, a fish with fins and scales, and a tablespoon of fish roe brings nearly two-thirds of a day's vitamin B12, plus omega-3s packed in the same fats your cell membranes are built from, for 21 calories. People in Japanese and other Asian food cultures ate fish roe as one of the most nutrient-dense foods they had,6 and human studies of herring roe and roe oil, from higher HDL cholesterol to calmer psoriasis, point the same way.

Choose tobiko made from flying fish roe and colored with real food such as wasabi, beet or yuzu, and leave dyed, flavor-enhanced and squid-ink versions on the shelf. Keep it cold, and check who should skip it raw first. The goal is more fish on your plate, not less,37 and a bright spoonful of tobiko on a plate of wild salmon is a delicious way to do it.

Tobiko: frequently asked questions

Is tobiko healthy?

Yes. A tablespoon of fish roe gives you 63% of the daily value for vitamin B12 and about 0.35 grams of the omega-3s EPA and DHA for 21 calories, and the healthiest tobiko is flying fish roe colored with real ingredients rather than dyes.1 2

What is tobiko made of?

Tobiko is flying fish roe cured with salt.11 12 Some versions add flavor and color, such as wasabi flavor, sorbitol, sugar and FD&C dyes, so the ingredient list tells you what you're getting.26 27

Is tobiko raw?

Yes. Tobiko is cured with salt rather than cooked, and like other roe products it's kept refrigerated or frozen until it's served.12

Is tobiko good for omega-3s?

Yes, for its size. A tablespoon of fish roe carries about 0.35 grams of EPA and DHA, and in a trial in which 32 adults each tried both, phospholipid-rich roe oil raised blood omega-3s more over 12 hours than fish oil.1 17

How many calories and how much protein are in tobiko?

About 21 calories and 3.3 grams of protein per tablespoon (15 grams), with 1 gram of fat, based on USDA's record for fish roe.1

Is tobiko high in cholesterol?

A tablespoon of fish roe has 56 milligrams of cholesterol, 19% of the daily value.1 2

What's the difference between tobiko and masago?

Tobiko is flying fish roe and masago is capelin roe, and both fish have fins and scales.32 Capelin roe is sometimes sold in place of tobiko, so look for flying fish roe on the label.11

What's the difference between tobiko and ikura?

Ikura is salmon roe. In a Japanese analysis of salted roe products, ikura had more total fat and cholesterol than tobiko, while tobiko's phospholipids carried a higher share of DHA.16

What is black tobiko?

Black tobiko is flying fish roe colored black, with FD&C dyes on one U.S. label (Red 40, Blue 1, and Yellow 5 and 6) or with squid ink.14 Skip both. Artificial colors are on the list of additives to put back on the shelf, and squid doesn't have both fins and scales, the standard I follow.15 28

What is wasabi tobiko?

Wasabi tobiko is flying fish roe flavored and colored green. Check the label, because one U.S. version is colored with FD&C Yellow 5 and Blue 1, flavored with wasabi flavor rather than wasabi, and blended with herring roe.27

What are red and yuzu tobiko?

Red tobiko is flying fish roe colored red, and yuzu tobiko is flavored with the citrus fruit yuzu. Choose versions colored with real ingredients, such as beet juice for red, and skip Red 40 and Yellow 5 and 6.

How much tobiko can you eat?

A tablespoon or two at a meal, as an occasional finish on a fish-forward plate. One tablespoon of fish roe already gives you 63% of a day's vitamin B12.1 2

Can you eat tobiko while pregnant?

Skip raw tobiko while you're pregnant. FDA advises pregnant women to avoid raw fish such as the kind found in sushi.5 Get your 8 to 12 ounces of fish a week from cooked, lower-mercury choices instead.35

Can children eat tobiko?

Skip raw tobiko for young children. FDA lists children among the groups who should avoid raw fish, so serve them cooked, lower-mercury fish instead.5 35

Does tobiko have mercury?

A tablespoon of tobiko is a small serving, and roe forms in an organ that carried less mercury than the meat in a French study: in hake, red mullet and sole, mercury ran higher in each fish's muscle and liver than in its gonads.43 Flying fish roe itself hasn't been well studied for mercury.

Is tobiko kosher?

Flying fish, the source of tobiko, is on the Orthodox Union's list of kosher fish, which covers fish with fins and scales.32 Colors and flavorings are added separately, so look for kosher certification on the package.
