Ginger beer sits in an awkward spot between health food and soft drink. The ginger itself carries real, well-studied benefits for digestion, nausea, and inflammation, but most commercial ginger beers dilute those benefits with large amounts of sugar and very little actual ginger root. Whether a bottle of ginger beer is good for you depends almost entirely on which bottle you pick up and how it was made.
What Ginger Actually Does in Your Body
Ginger root contains a family of pungent compounds, the most studied being gingerols and shogaols. These are responsible for ginger’s sharp, warming bite, and they also drive its medicinal effects. Gingerols are the primary compounds in fresh ginger, while shogaols form when ginger is heated or dried. Moist heat in particular converts gingerols into shogaols efficiently, with higher temperatures accelerating the process.1PubMed Central. Heat-induced conversion of gingerols to shogaols in ginger as affected by heat type (dry or moist heat), sample type (fresh or dried), temperature and time In water-based preparations like beverages, gingerols are thermally unstable and readily convert to shogaols, meaning the brewing or cooking process itself changes the chemistry of the ginger you end up drinking.2PubMed.

This matters because shogaols tend to be more potent than gingerols in laboratory studies, particularly for anti-inflammatory and antioxidant activity. So a well-brewed ginger beer that uses real ginger root and involves heat could, in theory, deliver a more bioactive profile than eating a slice of raw ginger. The catch is that “could, in theory” is doing a lot of heavy lifting. Most commercial producers use ginger flavoring or extract in quantities designed for taste, not therapeutic effect.
The Nausea and Digestion Evidence
The strongest evidence for ginger’s health benefits involves nausea and stomach motility. In a trial of healthy volunteers, ginger sped up the rate at which the stomach emptied after a meal, roughly halving the time compared to a placebo.3PubMed. Effects of ginger on gastric emptying and motility in healthy humans A separate study found a similar pattern, with the stomach’s half-emptying time dropping from about 16 minutes with placebo to about 12 minutes with ginger.4PubMed Central. Effect of ginger on gastric motility and symptoms of functional dyspepsia If you feel bloated or sluggish after eating, faster gastric emptying is genuinely helpful.
For motion sickness, ginger at doses of one to two grams reduced nausea, delayed the onset of symptoms, and shortened recovery time in a controlled trial using a rotating visual drum to simulate motion.5PubMed. Effects of ginger on motion sickness and gastric slow-wave dysrhythmias induced by circular vection A larger clinical evaluation found that ginger extract significantly reduced motion sickness symptoms across repeated sea voyages.6PubMed Central. Clinical Evaluation of the Use of Ginger Extract in the Preventive Management of Motion Sickness A systematic review of randomized trials found that the evidence collectively favored ginger over placebo for seasickness, morning sickness, and chemotherapy-induced nausea, though for postoperative nausea the pooled results were not statistically significant.7British Journal of Anaesthesia. Efficacy of ginger for nausea and vomiting: a systematic review of randomized clinical trials
The practical takeaway is that ginger reliably helps with nausea and sluggish digestion. Reaching for a ginger beer before a boat trip or when your stomach feels off is not a folk remedy without basis. But the doses used in these studies, typically one gram or more of dried ginger root, are far higher than what most ginger beers contain.
The Dose Gap Between Studies and Your Bottle
This is where the “good for you” narrative starts to wobble. Clinical trials use standardized ginger powder, extract, or capsules at known doses. A typical anti-nausea dose is around one gram of dried ginger root. Ginger beer, on the other hand, is not standardized at all. A review of ginger-flavored beverages noted that ginger beers contain more than 0.5% ginger by volume, while ginger ales contain about 0.5%, but actual ginger content varies enormously by brand.8PubMed Central. Essential Oils in Ginger, Hops, Cloves, and Pepper Flavored Beverages-A Review That same review found a lack of data on the actual levels of bioactive compounds in finished ginger beverages, making it essentially impossible to know how much gingerol or shogaol you’re getting per serving.
Some craft and artisan ginger beers use large quantities of fresh ginger root and may approach a meaningful dose. Mass-market brands, however, often rely on “natural ginger flavor” and contain trace amounts at best. Reading the ingredient list is the only real guide: if ginger root, ginger juice, or ginger extract appears high on the list, you’re probably getting more than if “natural flavoring” is buried near the end.
The Sugar Problem
A standard 12-ounce bottle of commercial ginger beer can contain 30 to 40 grams of sugar, comparable to a regular cola. Some premium brands push even higher. That amount of added sugar offsets most of the digestive or anti-inflammatory benefits ginger might offer, especially if you’re drinking ginger beer regularly.
This is not a minor quibble. Ginger itself has been studied for its effects on blood sugar. In patients with type 2 diabetes, ginger supplementation significantly reduced fasting blood glucose and a key marker of long-term blood sugar control compared to placebo.9PubMed Central. The Effects of Ginger on Fasting Blood Sugar, Hemoglobin A1c, and Lipid Profiles in Patients with Type 2 Diabetes A broader review of ginger’s metabolic effects found it plays a beneficial role in metabolic syndrome through its blood-sugar-lowering, fat-lowering, and blood-pressure-lowering properties.10PubMed Central. The effects of ginger and its constituents in the prevention of metabolic syndrome: A review Drinking a sugar-heavy ginger beer to get those metabolic benefits is self-defeating. You’re pouring in the very thing ginger is supposed to help counteract.
Lab-formulated ginger-based fruit drinks have been shown to produce low glycemic responses and inhibit carbohydrate-digesting enzymes, but these were carefully composed beverages with controlled sugar content, not off-the-shelf ginger beers.11PubMed. Antioxidant properties, glycemic indices, and carbohydrate hydrolyzing enzymes activities of formulated ginger-based fruit drinks If you want ginger beer to work for you metabolically, you need to seek out low-sugar or sugar-free versions, or make your own with minimal sweetener.
Traditionally Fermented Ginger Beer Is a Different Product
Most of what you find in stores is not fermented at all. It’s carbonated water, sugar, and ginger flavoring, force-carbonated with pressurized carbon dioxide. Traditional ginger beer, by contrast, is fermented using a “ginger bug,” a starter culture of wild yeasts and bacteria fed with sugar and fresh ginger. This fermentation process produces natural carbonation, organic acids, and a complex microbial community.
Research on home-brewed ginger beer has identified the presence of lactic acid bacteria, including Lactococcus, along with other microorganisms that hint at probiotic potential, though the researchers emphasize that in vivo studies are needed before making health claims.12Journal of Food Hygiene and Safety. Microbial Characterization of Home-Brewed Ginger Beer Using Culture-Dependent and Independent Methods A study characterizing the fermentation process found that longer fermentation times (around 14 days) produced ginger beer with higher levels of organic acids, phenolic compounds, greater microbial diversity, and better sensory qualities than shorter ferments.13PubMed. Ginger beer derived from back-slopping: Volatile compounds, microbial communities on activation and fermentation, metabolites and sensory characteristics
The fermentation also consumes some of the sugar you start with, meaning a well-fermented ginger beer will be less sweet than the same recipe pre-fermentation. It won’t be sugar-free, but the residual sugar depends on how long you let the fermentation run. If you brew your own, you control both the ginger quantity and the sugar level, making it a genuinely healthier product than anything commercial. Longer activation of the ginger bug (around 96 hours) also resulted in higher production of organic acids, more lactic acid bacteria, and more diverse microbial populations.
Ginger Beer Versus Ginger Ale
People often use these names interchangeably, but they’re different drinks. Ginger ale typically contains less ginger (around 0.5% by volume), is carbonated artificially, and has a milder taste. Ginger beer historically contains more ginger, was traditionally fermented, and has a much more assertive flavor. In practice, though, many modern commercial ginger beers have drifted toward the ginger ale model: artificially carbonated, lightly flavored, and heavily sweetened.
If you’re drinking ginger beer specifically for health reasons, the distinction that matters is not the label but the method. A fermented ginger beer with real ginger root and low sugar is a fundamentally different product from a sugary, force-carbonated drink with ginger flavoring, regardless of which one says “ginger beer” on the label. The same review that established the ginger content differences between ales and beers also noted that traditional ginger beers get their carbonation from yeast or a ginger beer plant culture, while ales rely on pressurized carbon dioxide.8PubMed Central.

Anti-Inflammatory and Pain Effects
Beyond the gut, ginger has been studied for pain and inflammation. A narrative review of clinical trials found that ginger has a pain-reducing effect, working through several pathways: it inhibits prostaglandins (the same inflammatory molecules targeted by ibuprofen), acts as an antioxidant, and activates vanilloid receptors, the same receptors that respond to capsaicin in chili peppers.14PubMed Central. Clinical trials on pain lowering effect of ginger: A narrative review That vanilloid receptor activation also drives the warming sensation you feel when you drink something with real ginger, and it appears to boost thermogenesis, the process by which your body generates heat and burns calories.15PubMed Central. Ginger consumption enhances the thermic effect of food and promotes feelings of satiety without affecting metabolic and hormonal parameters in overweight men: A pilot study
A review of ginger’s cardiovascular effects found that its bioactive compounds may improve blood lipid profiles, reduce LDL cholesterol, and lower fasting blood glucose.16PubMed Central. Ginger: A Nutraceutical Supplement for Protection Against Various Cardiovascular Diseases in Clinical Trials These findings come from studies using concentrated ginger supplements, not beverages. Still, if your ginger beer is genuinely ginger-rich, you’re getting some of these compounds with every sip. The question is always how much.
What About Your Teeth
Ginger beer is acidic. Most commercial varieties have a pH low enough to erode tooth enamel over time. Research on common beverages has shown that drinks with pH values below about 4.0 can cause measurable enamel erosion within minutes of contact, with some beverages reducing enamel hardness by a quarter or more.17Australian Dental Journal. Erosive effects of common beverages on extracted premolar teeth Ginger beer typically falls in the pH 3 to 4 range. Fermented versions may be even more acidic due to the organic acids produced during fermentation. Drinking it through a straw, not swishing it around your mouth, and rinsing with water afterward are simple ways to reduce the damage.
This is not unique to ginger beer. Nearly all carbonated drinks, fruit juices, and fermented beverages share this problem. But it’s worth keeping in mind if you’re drinking ginger beer daily for its health benefits, because the dental erosion adds up over weeks and months in a way that occasional sipping does not.
Ginger Beer During Pregnancy
Ginger is one of the most commonly used herbal remedies for morning sickness, and pregnant women often reach for ginger beer as a palatable way to get it. The safety data here is reassuring. A large population-based study of over 68,000 women found that ginger use during pregnancy was not associated with any increased risk of birth defects, stillbirth, preterm birth, low birth weight, or low Apgar scores.18PubMed. Safety of ginger use in pregnancy: results from a large population-based cohort study
A systematic review concluded that ginger is a safe and effective treatment for pregnancy-related nausea and vomiting, though it noted that the maximum safe dosage and ideal duration of treatment remain uncertain.19PubMed. The effectiveness and safety of ginger for pregnancy-induced nausea and vomiting: a systematic review A separate review found that about one gram of fresh ginger root per day for four days showed a significant decrease in nausea and vomiting with no risk to the mother or baby.20PubMed Central. How Safe Is Ginger Rhizome for Decreasing Nausea and Vomiting in Women during Early Pregnancy?
The caveat for ginger beer specifically is again the sugar. If you’re managing gestational diabetes or trying to limit weight gain, a high-sugar ginger beer is not the ideal delivery vehicle. A ginger tea, ginger capsule, or low-sugar homemade ginger beer would provide the anti-nausea benefit without the glucose spike. Some commercial ginger beers also contain trace amounts of alcohol from residual fermentation, which is another consideration during pregnancy. Check labels carefully.
Alcohol Content and Labeling
Most commercial ginger beers sold as soft drinks contain less than 0.5% alcohol by volume, which is the threshold below which a beverage can be labeled non-alcoholic in many countries. Traditionally fermented ginger beers can have higher alcohol content depending on how long they’re fermented and how much sugar was available to the yeast. Alcoholic ginger beers sold as such can range up to about 11% alcohol by volume. The substitution of different types of sugar in ginger-based fermented beverages has been shown to significantly influence the resulting alcohol content.21IOP Conference Series: Earth and Environmental Science. pH Value, Total Microbes, Alcohol Content and Overall Hedonic Characteristic of Ginger Ale
If you’re avoiding alcohol entirely, whether for pregnancy, medication interactions, or personal reasons, be aware that a home-fermented ginger beer or a craft “alcoholic ginger beer” may contain more than you expect. Mass-market brands sold alongside other soft drinks are consistently below the 0.5% threshold and are functionally non-alcoholic.
Heavy Metals in Ginger Root
One concern that rarely comes up in the ginger-beer-is-healthy conversation involves contaminants. Ginger root can absorb and accumulate heavy metals from the soil it’s grown in, which raises a potential health concern depending on where the ginger was sourced.22PubMed. Bioaccessibility and bioavailability evaluation of heavy metal(loid)s in ginger in vitro: Relevance to human health risk assessment This is not a reason to avoid ginger or ginger beer, but it does argue against treating ginger beer as a daily health tonic consumed in large quantities. Occasional or moderate consumption poses negligible risk. If you’re making your own ginger beer and buying ginger root in bulk, sourcing from reputable suppliers and ideally organic sources reduces exposure.
This issue applies to ginger in all forms, not just ginger beer. But because the health-food framing of ginger beer can encourage heavier consumption than you’d get from occasional cooking, it’s worth noting. The dose makes the poison, as the old saying goes, and that applies even to foods with genuine health benefits.
How to Make Ginger Beer Work for You
If you want to actually capture ginger’s benefits in a beverage rather than just enjoying a spicy soda, here’s what matters:
- Use real ginger root: Fresh ginger steeped or boiled in water extracts gingerols and shogaols. The longer and hotter the brew, the more shogaols form and the more pungent the result.
- Minimize sugar: Use just enough to feed fermentation if you’re making a live ginger beer, or sweeten lightly with honey or a low-calorie sweetener. The goal is to stay well below the 30-plus grams in a typical commercial bottle.
- Ferment if possible: A ginger bug starter produces natural carbonation, organic acids, and a microbial community that may offer probiotic benefits. Even a short ferment of a few days adds complexity that force-carbonated drinks lack.
- Watch the acidity: Rinse your mouth with water after drinking, and avoid brushing your teeth immediately after, since brushing softened enamel can cause more damage than waiting.
Commercial options vary wildly. Some brands use organic ginger juice, minimal sugar, and live cultures. Others are indistinguishable from ginger-flavored soda. The ingredient list and nutrition label are more informative than any marketing language on the front of the bottle. A ginger beer with 8 grams of sugar and ginger juice listed as the second ingredient is a categorically different product from one with 40 grams of sugar and “natural flavors” as the only ginger reference.
