Probiotics are live microorganisms, often called “good” or “friendly” bacteria. They occur naturally in the body and are also found in foods like yogurt and other fermented products. When consumed in adequate amounts, probiotics can play a role in supporting a balanced microbiome, which is linked to various aspects of health and well-being.

Scientists from the International Scientific Association for Probiotics and Prebiotics (ISAPP) emphasize that, by definition, probiotics must have a scientifically demonstrated health effect. It’s also important to know that benefits are strain specific—different strains support different areas of health.

Probiotics do not permanently take up residence in the gastrointestinal tract. Instead, most probiotic strains are considered transient, which means they move through the digestive system for a limited time. While passing through, they interact with the existing community of microbes, supporting balance and contributing to their studied health effects.

Even though they don’t establish permanent colonies, regular intake of probiotics can help maintain their presence and potential benefits. This is why probiotics are often recommended for daily use, so their effects can be continuously supported.

We recommend taking only the dosage listed on the product label. Each serving is carefully set to reflect the amount studied for effectiveness, so you can feel confident you’re getting the intended support without taking more than your body needs.

Refrigeration is not required. Our probiotic strains are shelf-stable for 18 months at ambient temperatures up to 79°F when stored in a cool, dry place. If your home is consistently warmer for extended periods, refrigeration in an airtight container may be helpful to reduce exposure to heat and moisture.

We recommend taking one capsule per day with a glass of water, ideally before beginning your morning routine.

However, there is no single best time of day to take our probiotics—the key is consistency. Choose a time that works well for you, and take it daily. Our probiotics can be taken on an empty stomach or with food, so you may choose whichever is most comfortable.

If you are pregnant or breastfeeding, we recommend speaking with your healthcare provider before starting Acavo. While our probiotics are formulated with high-quality ingredients and are generally considered safe, it is important to confirm that any new supplement is appropriate for your individual needs during this time. Your provider can give you personalized guidance based on your health and circumstances.

We know how frustrating this can be. If your order is marked as delivered but hasn’t arrived, start by checking with neighbors, household members, your mail carrier, and common drop-off spots around your home.

Sometimes packages are scanned as delivered a little before they actually reach your doorstep.

If your shipment arrives damaged, please reach out to support@acavo.com with a description and photos of the damaged product and we’ll be happy to assist.

At Acavo, we operate as a subscription company because probiotics work best with consistent, daily use. Unlike a one-time supplement that permanently “fixes” the an issue, most probiotics are transient visitors. They travel through your digestive system, interact with your existing microbiome, and are naturally expelled—meaning their benefits last only as long as you continue taking them. Consistency is the key: just like watering a garden, steady daily intake is what helps probiotics continue to support your health.

A subscription makes that consistency simple and reliable. It ensures you never miss a day, helps you stay on track with your health goals, and delivers fresh product right when you need it. This model also reflects our long-term commitment to your health: by removing the hassle of reordering and guaranteeing ongoing supply, we make it easier for you to sustain the benefits that only come with steady, uninterrupted use.

While subscriptions cannot be paused indefinitely, you can easily adjust your next refill to a date that works best for you by following these steps:

1. Log in to your account
   
2. Go to Subscriptions
   
3. Click Edit under the next shipment date
   
4. Choose your preferred option and click Confirm
   

Please note: Changes can be made up until the day before your order is scheduled to process.

We want you to feel confident trying Acavo, which is why your first order is covered by our 90-Day Love It or Your Money Back Guarantee. This applies to your first delivery—whether it’s a one-time purchase or the first shipment of a new subscription. If you’re not completely satisfied, simply email us at support@acavo.com within 90 days of receiving your order, using the same email address you used at checkout. No return is required unless we request it—in that case, we’ll cover the return shipping.

Your refund will include the full product price of your first delivery (excluding shipping and handling fees). Please note that this guarantee applies only to your first purchase from acavo.com and is limited to one refund per customer or household. If you request a refund on a subscription, we’ll pause or cancel it automatically to prevent further shipments—but you’re always welcome to restart anytime.

Once an order has been billed, we’re unable to cancel or make changes to it. However, you can easily reschedule your next refill so you have time to use what you already have on hand. All refills remain fresh until the expiration date printed on the bottle, so you can confidently store them until you’re ready to restock your jar. You may also update your subscription settings at any time to adjust future refill dates.
