This product has changed my life, literally healed my hiatal hernia and stopped all my acid reflux. I wouldn’t be without it. The Polyphenol is a booster and works great! I’ve also had great customer service- easy to skip shipments and suspend them if you’re traveling! Love this company!

I saw a Video of a Dr. William Li, a Top World Renown Doctor & researcher of what foods & supplements to take & eat in order to both help get well & recover Cancer patients of which I am battling with two types at this moment. I saw a video of Dr. William Li holding up a bottle of Pendulum Akkermansia Probiotic & then I placed an order . Exactly a week later I saw another Video of Dr. William Li stating that he has recently been the subject of some deep fake AI Commercials for products that he has NOT Endorsed at all. Turned out that this Pendulum brand was one of them! Then yesterday I received the order & it was for 2 different products, both one for the Akkermansia probiotics & one called Polyphenol Booster & I was not only charged $70. -But also they have set me up for a monthly subscription now& I cannot get anyone live to answer their phone customer service support. I am already a severely disabled senior on a tiny once a month income & am barely able to afford my medicines & foods, but I have Not even opened up either of the products boxes they come in & I would like my money to be returned back to my original method of payment & to be cancelled permanently from their monthly subscription service. I don’t know what to do now. I cannot get a live customer support agent to answer my phone calls & attempts to resolve this & get this taken care of immediately. Please can anyone help & assist me?

Hi Cherri, We’re so sorry for the confusion and frustration you’ve experienced. We completely understand your concern. To clarify, Pendulum is officially partnered with Dr. Li, who collaborates with us to share credible, science-based education about gut health and metabolism. Dr. Li recently made a public statement about AI-generated deepfake videos being used by other companies without his permission. We want to reassure you that Pendulum has never used AI-generated deepfakes in any of our marketing. Every video or ad featuring Dr. Li from Pendulum is part of our verified, official collaboration. We’re truly sorry that you had trouble reaching us, and we appreciate you bringing this to our attention. Our Care Team is reaching out to you directly to resolve your order and ensure your refund and cancellation are processed right away. Thank you again for sharing your experience. - The Pendulum Team
I was able to cancel my subscription in time before I received a second delivery BUT I HAD TO DO IT FAST when I got the email telling me it was on the way soon. You have to be SO CAREFUL on the website because the default setting is to create a subscription and you have to look at the top of the price list and CHOOSE "One Time Purchase" or you get signed up for 3, or 6, or 12 months. I was going to order again but saw there are complaints at BETTER BUSINESS BUREAU And all of them are about things like getting deliveries not ordered, or similar problems. I'm not sure I want to bother with this company again. Also there are a lot of questions by professionals about whether it even works. For the price... and the customer service problems...I don't feel like gambling

Hi Bea, Thank you so much for sharing your experience—we really appreciate the feedback and are sorry to hear about the frustration. We send an email five days before an order is set to process and ship, which gives time to make any needed changes. You can also opt in to receive text notifications for the same reminder, which some customers find helpful. Many manage their subscriptions directly through their online account, but our Customer Experience team is always happy to help with cancellations or adjustments if needed. If a subscription doesn't feel like the right fit, you can always choose the one-time purchase option directly on our website when placing an order. We also offer additional one-time purchase options through our Amazon store and iHerb, which some customers find more convenient. We’d love to hear how the product worked for you, and if you ever decide to continue, we're here to help you find the option that feels right for you. Warmly, The Pendulum Team
Very impressed by customer service and quick responsiveness!

We ordered one item for the first time. We received an email today saying we would receive our next order on 7th July and our card would be charged. When I looked on the website it had a automatic order set for each month. When I phoned the number on portal it said it was not connected. I had to go through and hit skip to every date that had the next month order listed. Hopefully the orders are cancelled and my credit card is not charged. I never signed up for repeat orders or gave them permission to charge my card. I have sent 2 emails so hopefully they respond and I don't lose any money. Very unhappy feel scammed.

Hi Kim, We’re really sorry for the frustration this caused and completely understand how upsetting that must have felt. Thank you for taking the time to share what happened. Even though some time has passed, your feedback is still incredibly valuable to us. Pendulum offers both one-time purchases and subscriptions, and we want those options to be as clear as possible. We’re also sorry you weren’t able to reach us by phone at the time. Our support line is active, and our team is always available by email at [email protected] if you ever need help in the future. We take situations like this seriously and appreciate you bringing it to our attention. - The Pendulum Team
I recently purchased a 3-month supply of @pendulumlifeco probiotics. For some reason, the order was abruptly cancelled along with the membership, and nothing was ever shipped out. On top of that, I now have a $245 charge on my card for which no refund has been issued. To make matters worse, I attempted to reinstate my membership and place a new order, but cannot get the new customer discount using an influencer’s discount code. I have reached out to hello@pendulum[…] and cannot seem to get a response. On their website is an AI chat feature that can connect to a live representative. However, the split second the agent enters the chat, the chat is immediately ended. Please understand that if you ever need customer service for this product, you are literally on your own. No human will ever respond.

Hi Natalie, Thank you so much for reaching out, and I’m truly sorry for the frustration and disappointment caused by your first order being canceled. We completely understand how frustrating this must be—especially when you were giving us a try for the very first time. I see that my colleague Christine has followed up with you and explained that your order was canceled due to our security checks. These are in place to help protect your account, but unfortunately, our system made an error in this case. I genuinely apologize for the inconvenience. The good news is that your refund has already been processed, and it should appear on your statement within 3–7 business days, depending on your bank. We’d love the opportunity to make this right and show you the experience we aim to provide. If you decide to place a new order, your new-member discount code is still valid—we hope you’ll give us another chance. Please let us know if there’s anything else we can do to help. Yours in gut health, The team at Pendulum
Gave it a few months to see initial results. After 3 months it seemed a bit better so I continued with it, but that was very short lived. Does not help reduce hunger and I have more intestinal gas and bloating now after 4-5 months than I have had in my life. If it works for you, I truly believe it is a placebo effect and good for you, then keep it up. I simply do not find that the cost is worth the results. I am done with them.

Hi MJK, We’re really sorry to hear that you didn’t get the results you were hoping for and truly appreciate you giving Pendulum several months to see how it might work for you. Everyone’s gut microbiome is unique, and while some people notice changes within a few weeks, for others it can take longer—or sometimes require a different approach. We completely get how frustrating that must feel after putting in the time and investment. Your feedback helps us continue improving how we educate and support customers through their gut health journey. If you’d ever like to talk through your experience in more detail, our Care Team is always here to help at [email protected]. Thank you again for sharing your honest perspective. It helps us grow and serve our community better. 💜 - The Pendulum Team
Very very hard to manage subscriptions. Have tried contacting them via email with no response. Have ended up removing my CC details so that my orders decline instead of cancelling my subscription.

Hi Lorena, I'm Lauren from the Customer Care team at Pendulum. I'm very sorry to hear that you had trouble canceling your subscription; we try to make account management through the portal easy but apologize that we missed the mark this time. I will pass your experience on to our Website team so they can consider improvements to make this process easier in the future. I know you mentioned the failed payment is working for you, but I'd be happy to cancel your subscription for you. I tried to find your account but I'm having some trouble finding it. If you would like us to cancel it, please email us at [email protected]. Again I sincerely apologize for any inconvenience this has caused!
