Frequent Questions
Is Synbiotic+ right for me?
Synbiotic+ is a 3-in-1 clinically-studied prebiotics, probiotics, and postbiotic to support a balanced gut microbiome.*
Probiotics are only able to stay in the gut for a few days or weeks at a time, and consistent use can help support the benefits (hello gut health, digestive health, and immune health) of the clinically studied probiotic strains.*
What purchase and delivery options does Ritual offer?
1-Month Subscription: Enjoy automatic delivery of a 30-day supply every 30 days with free shipping for convenient, consistent replenishment. All subscriptions renew automatically, but you’re always in control. You can pause, skip, change your delivery date, or cancel anytime from your Account Page.
What testing do you complete for HyaCera™?
Each batch of HyaCera™ is tested for identity and dose so we can be sure that what’s on the label is what’s in the capsules. We also complete Third-Party testing to ensure our products are compliant with regulations and guidelines for heavy metals and microbes and to help assure the quality and safety of our products.*
What is the packaging made from?
The current packaging is made from mixed materials, including polypropylene for the bottle and 100% PCR polypropylene for the cap. The bottles are not currently recyclable due to their mixed materials, but we are continually looking for updated formats that allow us to deliver a fresh product in a sustainable format.
Additionally, your first month is shipped in a recyclable box, and recurring orders are shipped in mailers made from 100% recycled content (the paper used to make our mailers is 100% garbage-repurposed newsprint and plant fibers). Any collateral included is also made of 100% recycled materials.
What can I expect while taking Synbiotic+?
When first starting, your gut microbiome may need time to adjust. You may experience side effects such as minor gas, bloating, or stomach rumbling, which should subside with ongoing use. Consult your healthcare professional if symptoms continue after two weeks.
That said, like any new diet change, by constant use, the body will begin to acclimate to the introduction of daily prebiotics, probiotics, and a postbiotic. Probiotics are only able to stay in the gut for a few days/weeks at a time. Consistent use helps support the benefits of the clinically studied probiotic strains.*
Can I take Synbiotic+ if I am pregnant or nursing?
Synbiotic+ has been evaluated in a safety study to be safe for use by pregnant and nursing women. However, we recommend that you consult your healthcare practitioner before using if you are pregnant or nursing.

I have tried numerous digestive supplements over the years, but the Ritual Synbiotic+ stands out as the most thoughtful and effective formula I have encountered. The 3-in-1 design combining prebiotics, probiotics, and postbiotics simplifies my routine significantly by eliminating the need for multiple different bottles.
The most immediate benefit I noticed was the design of the capsule itself. The delayed-release technology is a game changer for anyone with a sensitive stomach, as it ensures the ingredients reach the gut where they are actually needed rather than dissolving too early. Additionally, the mint-scented tab included in the bottle makes the daily experience much more pleasant than the typical medicinal smell associated with most probiotics.
After consistent use for a full month, the results are undeniable. I have experienced a significant reduction in occasional bloating and a noticeable improvement in overall digestive regularity. It feels like my system is finally in sync. I also appreciate the peace of mind that comes with Ritual's commitment to traceable ingredients and third-party testing. Knowing exactly what I am putting into my body and why it is there is a level of transparency that is rare in the supplement industry.
While the price point is higher than some generic options, the quality of the vegan-friendly ingredients and the visible results make it a worthwhile investment for my long-term health. It is a premium product that delivers on its promises of digestive and immune support without any of the common side effects.

I have taken this supplement for 21 days. I have taken probiotic supplements for decades and prebiotic supplements for a couple of years.
My first week on Synbiotic didn't feel any different than with other supplements. After about 12 days on Synbiotic I noticed I was not having food cravings or thinking about my next meal all the time. I was thinking about it after a few days of not having cravings, and I realized it must be this supplement because nothing else had changed in my diet or routines, so I looked up the benefits of postbiotics online, and sure enough, a decrease in cravings can be a benefit. Some of the information I ran across indicated that postbiotics are linked to mental health and feelings of well-being, and can even help people with serious mental illness diagnoses,. When I read that, I realized that I had definitely had less stress responses and a more positive outlook to dealing with work stress and employee issues that usually get to me. That sold me, and I put Synbiotiic on subscription!
Because fermented postbiotics can have strong odors, there is disc in the supplement bottle that is saturated with a strong mint oil. It took me 3 days, then on the 4th day of having a burning feeling in my esophagus that kind of felt like heartburn, which I almost never suffer from, I realized that the mint oil clinging to the outside of the capsules was irritating my esophagus. I poured the remaining capsules into a bowl and now store them that way, then give each capsule a quick rinse before I take it and that has alleviated the problem.
If I take the supplement with food, I get a little digestive upset, the best results for me are taking it on an empty stomach first then in the morning at least a half hour before eating, with plenty of water or green tea.
I seem to be getting the same amount of digestive and immune support as I was on other brands of probiotics and prebiotics, but the new results of the postbiotic support are impressive and make the slightly higher monthly cost of this product worth it.

I've been using Ritual's Synbiotic+ Probiotic, Prebiotic, and Postbiotic 3-in-1 formula for a few months now, and I can confidently say it deserves a solid five stars! This supplement has made a noticeable difference in my digestive health and overall well-being.
First off, the convenience of having a 3-in-1 formula is unbeatable. Instead of juggling multiple supplements, Ritual has combined everything you need for gut health into one easy-to-take capsule. The delayed-release design is a nice touch, ensuring the probiotics reach the right part of your digestive system to be most effective.
I’ve struggled with occasional bloating and irregular digestion in the past, but since starting Synbiotic+, I've noticed significant improvements. My digestion feels more balanced, and the uncomfortable bloating I used to experience has dramatically decreased. It’s also great to know that this product is designed with high-quality, traceable ingredients—no unnecessary fillers or additives.
The fact that it’s vegan, non-GMO, and free from major allergens is a big plus for me, as I try to be mindful of what I put into my body. The minty flavor is a small but appreciated detail that makes taking this supplement a more pleasant experience.
Overall, Ritual Synbiotic+ has been a game-changer for my gut health. It's effective, convenient, and made with clean ingredients that I trust. If you're looking for a reliable probiotic supplement that covers all the bases, this is definitely worth trying. Five stars!

I started taking this in January 2025 after reading a review from someone who said it helped with her lactose intolerance. I decided to give it a try, and I’m so glad I did because it really worked for me.
After about 1–2 months, I already started to feel a difference. My sensitive stomach improved a lot, and I stopped getting random diarrhea for no reason. Now, almost a full year later, I rarely need to take Lactaid before eating dairy products.
The only time I still take Lactaid is if I’m having a very heavy cheese meal or a full glass of milk. Otherwise, if I have a scoop of ice cream, some cheese, or foods with some dairy, it’s no longer an issue for me.
This has truly been life-changing, especially when traveling. I won’t go a day without it. It’s also so easy to take — just one pill after breakfast daily does the job.
Highly recommend for anyone dealing with lactose intolerance or a sensitive stomach!

Genuinely such an impressive little bottle of pre-, pro-, and post-biotics all in one and as a self-stable option not requiring refrigeration - makes taking all necessary "biotics" a breeze instead of buying individual options that often come in ugly containers or require space in the fridge. It also has a slight mint scent which makes me nauseous but swallowing is easy and of course the scent disappears after you eat it. I'd rather they change the scent to like a citrus but hey, not too bad.
A major issue is why is this company concealing or not making the full ingredients clearly and easily visible? It should be shown visibly in the preview images and it is not - A MAJOR CONCERN and one which leads to dubious confidence in this brand and the ingredient's authenticity. Hope they rectify this immediately
Additionally, I do wish that the price was lower because its rather too pricy to justify (seller/manufacturer please be more cost competitive as its hard to want to purchase this again due to the price) and also, as shown in my photo, I don't see why they'd ruin the front of the light blue bottle by putting the sticker there! Thankfully I was able to rinse and scrub off but it left a tad of sticky residue. Not like that's a major factor but an annoyance that could ruin the design for others if they don't take the time to remove the sticker or have issues with it successfully coming off without other steps. Its just such a pretty aesthetic, care for your full presentation! I say this especially as I plan to order more and use this bottle continually for storage if it goes well.
I just received it so too early to tell if I notice a difference with its impact or effectiveness but looking at the ingredients and percentage, it looks like a fantastic option and worth the price though of course I still think it could be slightly more competitive/accessible yet for what you're paying for, seems to be promising. I also think the technology and design of these seem to have such potential, hope it turns out to truly be one of the best options on the market. Thanks for designing and offering something that is both aesthetically pleasing, healthy, and geared toward optimal health

Solid Daily Gut Support with a Smart Formula 🌿💊
I’ve been taking this Synbiotic+ daily and it’s become a nice addition to my routine. The blend of probiotics, prebiotics, and postbiotics helps support digestive comfort, regularity, and overall gut balance — especially after heavy meals or travel. The delayed‑release capsule means it’s designed to get the good bacteria where it matters most, and I like that it’s vegan and doesn’t need refrigeration. 
After a few weeks, I noticed less bloating and more consistent digestion, which feels like a win. A few friends mentioned mild gas at first as their systems adjusted, but that eased up quickly with continued use. 
Bottom line: Great choice if you want a clean, everyday synbiotic supplement that’s easy to take and can help keep your gut feeling balanced — just give it a bit of time to show results! 🌱

When I was younger, I took antibiotics for my acne for a few years. I decided to stop them my acne came back worse than ever. I gave up dairy and the acne stopped. I’ve had weak moments when I eat dairy and every time, I would break out. I have been taking probiotics and prebiotics ever since the antibiotics. I’ve switched brands from time to time. Once I switched to Ritual and I had a weak moments and had dairy, I didn’t break out. I was surprised so I ate a bit of dairy again, and didn’t break out. Now, I’m able to have dairy without any breakouts. I’ve been taking these synbiotics for over a year and I’m never switching!

Awesome 3 in 1 supplement if you suffer from any kind of frequent or occasional stomach/GI issues. The bottle is well made and its easy to get the lid on and off while still being secure and maintaining the freshness of the capsules. The capsules both taste and smell really good and minty, I was both surprised and pleased by this. The capsules start working fast to provide all sorts of relief once you take them, saw a huge improvement in my GERD symptoms and these are great to take if you've overeaten and given yourself an upset stomach, they work wonders for bloating. The only issue I have with the product is in the color choice for the font, its white and very hard for me to see on the light grey bottle, it made reading the product information and directions challenging at first, a darker font would definitely be easier to see and read.

Expensive, but they work like nothing else. I hate the fact that I have to pay $60 a month for these, but they truly are amazing. I have not tried anything that even remotely compares to how regular these keep me. Plus, they have an amazing minty flavor. 10/10

First off...the label is so hard to read that you can barely tell what strains are in the capsule. I see that now that the product listing does show the 'Supplement Facts' which is very helpful. Second, once I started this I did notice an increase in energy levels BUT....I had very high anxiety symptoms that started 48 hours after the first capsule. I endured 9 days of this. I did some research and found that certain strains can in fact increase anxiety. I haven't taken a dose for 24 hours and I already feel much less anxiety. So, be aware of this...
Deducted a star for poor label design. Can't blame the ingredients. Again, I did have energy, but lousy anxiety, and no way to know that unless you take it and see how your body responds.

I am giving a 3 star because I’ve only been taking this product for 3 weeks. I have noticed subtle differences. But reading up on it and the full effect takes approximately 4-8 weeks so I reordered it to get me to the full 8 weeks. Will see. Hope this review helped to those that are on the fence to whether take it or not. It can’t hurt you for all I know so what’s the loss besides the price. ***After taking this a full 8 weeks I stopped taking for one week. Now I am realizing that it was helping and I didn’t notice how much. I am having issues that I didn’t have before. So I purchased again and hope it improves. I guess it just takes time to readjust your stomach. Give it time and it will work.

So good for my bell bell! First off I love the container. I wasn’t sure about the container until I fully read the container and looked up the container and what it uses were for and then I realized it’s a protective format to protect what’s inside and keep everything stabilized and secure for when you’re about to take this product. Which I think is amazing and innovative, most bottles or shipments that need some type of extra barrier protection, come with a little tiny, etc., to work out the moisture and keep it secure, but the whole bottle itself does that which is phenomenal very impressive. OK, let’s get to the actual Formulate inside the bottle. It is fantastic for your gut health issues or just general overall gut health improvement. So easy to take and use did not experience any side effects i.e. any major bloating or discomfort or pain which sometimes happens with some other brands or products this product is formulated for your body. It somehow knows to get in to your bloodstream and your intestines And give you that relief and comfort and support that you need. I definitely definitely recommend this product to anybody with good health issues or just wanting to improve your gut health balance all over it is a winner for sure!

Bought for travel when I can't take my liquid probiotic with me. The mint smell is lovely and these seem to work well. Very similar to SEED brand, but at a much better price point, especially since you only take 1 per day!

Absolutely the best Probiotic I have ever used. Minty fresh when you open the container. Peppermint Heaven.
Through the years I have used almost every probiotic on the market. I think you will really like it too. My daughter works in the medical system and was having stomach issues. it came from a reliable source.

I’ve tried almost every probiotic out there and have a passion for researching and exploring new findings. I live a very healthy lifestyle—no gluten, dairy, hydrogenated oils, or sugars. My daily focus is gut health because 80% of the immune system relies on it. If your gut is healthy, you’ll live happily and rarely get sick.
I read about Tributyrin and its benefits for people with colon inflammation and ulcers. It’s also safe for those with SIBO and has many great properties. So, I decided to try it as a treat for my gut 😅, even though I don’t have these issues. The first capsule on an empty stomach caused diarrhea, but the next day was better. It improved my digestion without any side effects.
❌ The first downside is that the listing didn’t previously mention the strong peppermint flavor.
❌ The price is also high for just 300mg of Tributyrin, and I believe those with gut issues may need more than one capsule.
I’m writing this review after finishing the bottle and trying two other Tributyrin-based postbiotics. This one was the best! 👍

Okay, so I’ve tried a lot of gut health supplements, and most of them either tasted weird, did nothing, or turned me into a human air balloon. But Ritual Synbiotic+? Total game changer.
First of all, can we just take a moment to appreciate Ritual as a brand? Their whole vibe is clean, transparent, and actually chic—like if wellness got a makeover and stopped being weirdly intimidating. I already use (and love!) their multivitamins, so trying the Synbiotic+ was a no-brainer.
The capsule is vegan, easy on the stomach, and best of all—no gag-worthy taste. In fact, there’s this subtle minty flavor that makes it feel fresh, not like I’m choking down lab dust. A nice little ahhh moment before breakfast.
As for results? My digestive system has gone from moody roommate to quiet, polite houseguest. Less bloat, more regularity (we’re talking Gold Medal in Digestive Olympics), and I swear my immune system is vibing better too. I feel…balanced. Like my insides are finally on a team-building retreat.
Ritual makes it easy to be consistent with their sleek little bottle and delayed-release capsule (so it doesn’t just dissolve in your stomach chaos). Honestly, I look forward to taking it—and how many supplements can you say that about?
If you’re looking for a gut health hero that doesn’t taste like regret and comes from a brand you actually trust, this is it. Big fan, big love, happy gut.
