Buldak Just Broke a World Record. Here’s What One Sachet Does in Your Stomach, in Milligrams
Samyang’s own labels put more sodium in the Original than in the 2X Spicy. Denmark’s food lab put 7.8 to 27.8 milligrams of capsaicin in a sachet. The experiments that give volunteers a stomach ache use half a milligram to five.
For most healthy people, the evidence points to discomfort, not damage. Human studies produce stomach burning, pressure and moderate pain with 0.5 to 5 mg of capsaicin; a 2x Spicy sachet measured 7.8 mg in a Danish lab and 16.8 mg in Samyang's Korean lab, and the 3x Spicy 25.9 to 27.8 mg, so an ache after a bowl is the expected response at that dose. Reviews of the stomach lining find capsaicin inhibits acid secretion and protected volunteers against aspirin injury; they name H. pylori and painkillers as the ulcer causes. The number a dietitian would circle is sodium: 1,630 mg in a bag of Original, 71 percent of the Daily Value, more than the 2X Spicy's 1,360 mg.
For one hour on October 1, people around the world set a phone against a glass, tore open a sauce sachet, hit record, ate and uploaded. At 9:27 p.m. Pacific, after the official review, a Guinness World Records judge confirmed that 335 videos had qualified, 85 more than the previous mark, and Buldak, the Korean noodle people film themselves eating, held a title for the most videos of people eating instant noodles uploaded to TikTok in one hour. Samyang Foods announced the record on October 5 with the Stokes Twins as the faces of the attempt, a count of more than 300 bowls, and the Original and the Carbonara named as the night’s hero flavors.
The other thing people do after a bowl of Buldak is ask Google about their stomach: pain, cramps, ulcers, the lining, the morning after. So we read the packet, Samyang’s own heat ratings, and the one government lab report that has measured the capsaicin in a sachet: Denmark’s, from 2024, when three varieties came off the shelves and two went back. Then the human studies, dose by dose, against what a packet carries.
The packet: Four labels, and the number a dietitian would circle
Samyang America prints a full Nutrition Facts panel for each flavor. The Original lists 560 calories, 18 grams of fat, 86 grams of carbohydrate and 1,630 milligrams of sodium, which the panel puts at 71 percent of the Daily Value; the FDA sets that value at less than 2,300 milligrams a day. The surprise is the order. The 2X Spicy carries less salt than the Original, 1,360 milligrams, and so do the Cheese and the Carbonara. The heat comes entirely from the sauce, listing red pepper, capsicum oleoresin and red pepper seed oil; the noodle block is wheat flour, starch and palm oil.
| Flavor (one bag) | Heat, of 5 | Calories | Sodium |
|---|---|---|---|
| Original, 140 g | 4 | 560 | 1,630 mg (71%) |
| 2X Spicy, 140 g | 5 | 550 | 1,360 mg (59%) |
| Cheese, 140 g | 3 | 550 | 1,440 mg (63%) |
| Carbonara, 130 g | 2 | 550 | 1,330 mg (58%) |
The heat: Scoville, and the milligrams behind it
Samyang’s own Scoville figures live in a 2017 release on its Korean site: 4,404 for the Original and 8,706 for the double-strength version, “by the company’s own measurement” (our translation). Scoville converts to capsaicin at 16.1 SHU per milligram of total capsaicin per kilogram, the German factor Denmark uses, which is how the Danish episode started. On June 11, 2024, the Danish Veterinary and Food Administration ordered the 3x Spicy, the 2x Spicy and the Hot Chicken Stew off the shelves after DTU’s National Food Institute converted a retailer’s Scoville claims (more than 13,000, more than 8,000 and 4,705) into more than 113, more than 69.6 and 42.4 milligrams per packet.
Then the agency measured the sachets. DTU’s July 11 assessment prints the results: 40 sachets of each product homogenised in a Danish lab gave 25.9 milligrams of total capsaicin for the 3x Spicy, 7.8 for the 2x Spicy and 6.3 for the Stew. Samyang’s Korean lab found 27.8, 16.8 and 11.1. Cooked the Korean way, with sauce left behind in sachet, pot and bowl, the averages fell to 19.1, 8.9 and 6.8. DTU’s line was 11.8 milligrams, the lowest content measured in a single extreme chili chip that had put German teenagers in hospital during a filmed challenge, and on July 15 the agency cleared the 2x Spicy and the Stew because they did “not contain such high levels of capsaicin as stated by retailers in the marketing” (our translation). The 3x stayed off. Nobody has measured the Original; if Samyang’s 4,404 describes the sauce as the lab readings do, a 31.8-gram sachet works out near 9 milligrams, our arithmetic on a stated assumption.
A Danish lab found 7.8 milligrams of capsaicin in a 2x Spicy sachet. The experiments that give healthy volunteers a stomach ache use half a milligram to five.
On the way down: What those milligrams do in a stomach
Capsaicin works on TRPV1, the heat sensor that a 2004 review describes as “expressed by primary afferent neurons innervating the gut” and gated by real heat and acid as well as chili. In a Leuven trial, 0.84 milligrams of capsaicin as diluted Tabasco, delivered by tube to ten healthy people, produced burning high in the abdomen within five minutes and made a balloon in the stomach uncomfortable at lower pressure. A 0.75-milligram capsule in Vienna “mainly induced sensations of pressure, heartburn and warmth.” In Singapore, 42 healthy volunteers swallowed a 0.5-milligram capsule every 15 minutes until they had moderate pain; 38 got there, at a median of two capsules, for a median of eight minutes, with “minimal adverse events.” A 2x packet carries 8 to 17 milligrams by the two labs. The ache people search for is what those studies produced at a tenth of the dose.
Speed is less settled: 400 micrograms of pure capsaicin quickened stomach emptying in ten volunteers, while 20 grams of chili powder in a meal slowed it in eight and sped whole-gut transit. Reflux has its own study: 11 people with heartburn ate the same breakfast with and without 5 milligrams of capsaicin, and acid exposure and emptying did not change, but heartburn peaked at 120 minutes instead of 247. In a 2020 Bangkok trial, 2 grams of chili gave reflux patients more abdominal burning than placebo, and healthy volunteers no more symptoms at all.
The ulcer question: What the reviews actually say
A 2006 review concludes that chili “is not the cause for ulcer formation but a ‘benefactor,’” because capsaicin “does not stimulate but inhibits acid secretion” and raises mucus and blood flow in the lining; the causes it names are Helicobacter pylori and anti-inflammatory painkillers. A Singapore experiment gave 18 healthy volunteers 20 grams of chili half an hour before 600 milligrams of aspirin and scoped them six hours later: median injury score 1.5 with chili, 4 without. The Hungarian group that has studied this longest reports, across 198 healthy subjects and 178 patients, that capsaicin “prevented the indomethacin- and ethanol-induced gastric mucosal damage.” Sensitivity varies: DTU’s memo cites a 1972 gastroscopy study in which 13 of 20 volunteers showed no change in the lining after a chili solution and seven showed irritation. What a packet does, on this evidence, is hurt, not ulcerate.
On the way out: The burn, the urgency and the tolerance
Our wings piece covered the trials that fed people chili and timed their guts: transit did not speed up, but after three days of 5 grams of chili the rectum reported urgency at 18 millimetres of mercury instead of 22. Leuven researchers put capsaicin at the exit directly, applying 0.01 and 0.1 percent solutions to the rectal lining of 25 healthy volunteers and 48 people with IBS, and recorded “a concentration-dependent increase of urge and pain perception” in both. Same receptor, other end. Tolerance is measurable: in a six-week trial, 16 people with diarrhea-type IBS took chili capsules before meals and finished with less burning after food and a first-sensation threshold of 16 millimetres of mercury, up from 8. The milk hack has a trial. At Penn State, 72 people swallowed 30 millilitres of spicy tomato juice and then 40 of a test drink: whole milk, skim milk and Kool-Aid cut the burn most, water least, and skim matched whole, which the authors read as protein mattering more than fat (the senior author discloses consulting fees from food companies). A loose morning that outlasts a day is a different question; we have set out what is known.
The challenge: A record, a regulator and a sachet
Samyang’s release describes the attempt plainly: for one official hour, fans filmed themselves eating noodles, uploaded to TikTok, and the videos went to Guinness World Records for review. The only regulator to draw a line is Denmark. DTU noted that eating chili as food is to some degree self-limiting, because the burn stops you, and that a challenge is different because the point is to ignore it; the Danish Poison Line logged 14 calls in the two weeks after the recall, with stomach or mouth pain and vomiting that lasted a few hours, brand unrecorded. The agency’s standing advice: it “generally recommends being careful about eating very strong chili products” (our translation). Symptoms that outlast a bowl by more than a day are a question for a clinician.
The facts to carry: a bag of Original is 1,630 milligrams of sodium, more than the 2X; a 2x sachet measured 7.8 to 16.8 milligrams of capsaicin in two labs, the 3x about 26 to 28; the stomach-ache studies use 0.5 to 5; and nothing in the reviews ties a packet to an ulcer. Samyang Foods, Samyang America, Buldak, Guinness World Records, the Stokes Twins, TikTok, the Danish Veterinary and Food Administration and DTU had no involvement in this article. It is educational, describes what the cited labels, agency documents and studies say, and is not medical advice.
