Introducing the next generation of AG1

History of Improvement

A history of staying in step with science

At AG1, we are committed to continuously improving our formula to reflect the latest advancements in nutritional science. Now, we’re excited to introduce the latest upgrade – designed to make your daily routine even better.

Why the upgrade? As science advances, so do we. The latest research continues to highlight the crucial role of the gut microbiome. This upgrade of AG1 now includes an enhanced mix of well-studied bacterial strains – without changing your routine or our price.

01 — BACTERIAL CULTURES

5 new strains of clinically studied bacteria

At AG1, we’re fascinated by the latest research on the microbiome and its diversity. As studies continue to uncover more about the presence of different bacterial strains, we stay curious and committed to evolving our formula.

That’s why we’ve upgraded AG1 to include five new clinically studied strains of bacteria – reflecting the latest advancements in microbiome science.

FAQs

It’s our belief that a product designed to support nutrition should evolve alongside the research. Since 2010, we have continuously upgraded the AG1 formula, guided by the latest research on ingredients and nutrition, to provide customers with better efficacy, higher quality, and consistent taste. Based on a growing body of research on the role of friendly bacteria in the gut microbiome, AG1 now includes five new gut-friendly bacteria that have been clinically studied: Lactobacillus rhamnosus GG, Lactobacillus acidophilus NCFM, Bifidobacterium lactis HN019, Lactobacillus casei LC-11, and Lactobacillus plantarum LP-115. We also increased the amount of magnesium, offering even more comprehensive daily support.

Our upgraded formula maintains the same great taste and smooth texture. We conducted extensive sensory testing to ensure that the experience remains just as enjoyable.

Some people may experience mild digestive changes at first. That’s normal and a sign the friendly bacteria is doing its job. If you prefer to ease in, start with half a scoop for the first few days, then move up to a full scoop.

We’ve increased our commitment to quality by adding new clinically studied strains of bacteria and additional magnesium, while continuing to meet the highest standards for ingredient sourcing, safety, and purity. Despite these improvements, the price has not changed.

The new scoop is slightly larger than the original one (13 g rather than 12 g) to accommodate the added ingredients in the new formula. We’ve adjusted the pouch size accordingly, at no extra cost for you. Your experience should feel the same.

If your scoop is missing or damaged, reach out to our Customer Happiness team and we’ll be happy to send you a replacement. In the meantime, one heaped tablespoon is approximately equivalent to one scoop (13g).

The new scoop is slightly larger than the original one (13g rather than 12g) to accommodate the added ingredients in the new formula and give you the precise serving size needed each day. In other words, we recommend using your new scoop as soon as you receive it in your order.

No, we increased the pouch size to make sure the number of servings in your pouch remains the same. The scoop was adjusted to reflect the slight increase in serving size, so you’ll still get the same number of daily servings per pouch.

Yes, the old scoop is recyclable where facilities exist. Please check your local recycling guidelines for proper disposal. Or, feel free to reuse it—some customers repurpose it for other powders or kitchen needs.
