ZBiotics review: ingredients, side effects, and price

What ZBiotics Pre-Alcohol is

ZBiotics Pre-Alcohol is a small bottled probiotic drink. ZBiotics describes it as "a beverage containing a patented, genetically engineered probiotic (B. subtilis ZB183™)" that is "engineered to break down acetaldehyde", the compound your body makes as it breaks down alcohol. The company calls itself "Proudly GMO" and says it invented the probiotic using genetic engineering.

ZBiotics classifies Pre-Alcohol as a food and beverage product, not a drug. It also sells a second product, Sugar-to-Fiber, which is separate from Pre-Alcohol.

ZBiotics ingredients

The ingredient list on the ZBiotics product page is short: water, natural flavors, potassium sorbate, sodium chloride, and Bacillus subtilis ZB183™. The listing is "Manufactured for: ZBiotics Company" in San Francisco.

ZBiotics says Pre-Alcohol is gluten free, nut free, dairy free, sugar free, shellfish and fish free, vegan friendly and third-party tested. Its FAQ adds that it is free of all major allergens (dairy, eggs, fish, shellfish, tree nuts, peanuts, wheat, soy and sesame), is tested for them at least annually, and contains no artificial flavors.

How ZBiotics works

ZBiotics says ZB183 is engineered to produce the same type of acetaldehyde-clearing enzyme as the liver, and recommends drinking it before your first drink; we go through the mechanism and the evidence on does ZBiotics work.

ZBiotics side effects

The ZBiotics product page does not list side effects for Pre-Alcohol. It notes that the product contains live probiotic bacteria and suggests talking to your doctor if you have concerns about your gut health. The "adjustment phase" note on the same page (gas, bloating, changes in stool) is written about Sugar-to-Fiber, not Pre-Alcohol. ZBiotics' AI-generated review summary says some customers reported no ill effects while others reported significant side effects, and it does not name them.

On safety, ZBiotics says Pre-Alcohol is FDA-compliant (not FDA-approved) and that its ZB183 strain is generally recognized as safe under its intended use; more on does ZBiotics work.

A fast-acting DHM alternative to ZBiotics

ZBiotics is a liquid you plan ahead for. Joyrise is a capsule you can take while you're drinking or before bed, so you don't need to remember it before the first round. It's a different approach: a plant flavonoid, DHM, instead of an engineered probiotic. Compare the two directly on ZBiotics alternatives, and see how ZBiotics stacks up against Cheers on Cheers vs ZBiotics. Our Cheers Restore review covers the other big name.

Joyrise capsules are caffeine-free and made in the USA. Joyrise is a fast-acting Alcohol Metabolizing Aid: an all natural, patented DHM supplement built around dihydromyricetin from vine tea, with a delivery approach designed for maximum bioavailability and covered by U.S. Patent US11871770B1. The capsule label says to take 3 capsules while consuming alcohol, or before bed, and not to exceed 3 servings (9 capsules) per day. See the full label on our Alcohol Metabolizing Aid capsules page.
