I’m four days into replacing my lunches with the chocolate shake. It tastes like most other chalky protein shakes (ie: not very appealing). But the bigger issue is that it is causing a decent bit of GI distress. I am getting heartburn about an hour after drinking the shake, and am gassy/bloated for the rest of the day to the point of discomfort. I will keep trying till the full pack runs out. But probably won’t buy more.

Thank you for your feedback Robin! We have passed on your note about the flavor and consistency to our product development team - we make all of our shakes in small batches and are continuously improving our recipe to try and cater to as many unique palettes as possible! What we have also heard from some customers is that it may help to slowly transition into using the shakes, for example: 1. Begin with a half a portion first, and eventually work your way up to a full portion as your body adjusts to receiving this level of good nutrients 2. Start with a shake every-other day until your body adjusts 3. In the beginning, it may be helpful to have a baseline layer of food in your stomach prior to drinking the shake - which can help regulate your stomach acid. To make it easier, we recommend having this as a lunch, after a light breakfast. The light breakfast should help coat your stomach and help with bringing your body to the level of nutrients provided in each shake. We would love to continue the conversation and give more advice on how to better ramp on with Biome Secret shakes - if you reach out to [email protected] we will try our best to help!

customer service informed me that not only can the package not be opened, but that it can only be returned to the Germany facility, so if you live in the U.S., the postage will cost more than the product. This is a scam! I researched and found out that it would cost me $60 to send it to Germany. I researched this product for a while, read reviews and looked up ingredients and finally made a purchase. I received my order timely and I made my first shake today...It is horrible! I don't understand how anyone could drink this stuff, its chalky and it has an overly sweet gross flavor, I can't even imagine how they deem this to taste good. I bought the vanilla caramel so I could either add cocoa to make it chocolate or coffee granules or both. So, I have requested to return the unopened bag as well as the other 14 packets(comes in a bag containing 15 packets and I purchased two bags) however, in reading deeper into the return policy it states they will only take back unopened packs in the original shipping box. So beware, this product is so disgusting flavor wise and once you open it you are stuck with it, not a great policy for a company that claims customer satisfaction is a high priority. I absolutely do NOT recommend this product. After reaching out to the company, they have acknowledged my disappointment and frustration, and have provided a full refund to me. I greatly appreciate the extra work that this company put forth to make a satisfactory resolution to this problem.

Thank you for your feedback Margaret! We're very sorry to hear that our superfood flavor did not match your palette, unfortunately everyone's taste buds are unique and while we try hard to make a product that will be liked by everyone - we know that ultimately it's not possible to have everyone like our shakes. We are 100% welcoming of unopened master pack returns and provide a full refund on those that are received back at our warehouse. Some customers choose to buy multiple master packs and open one at a time. We value transparency and this is why we suggest that customers begin with a smaller order for a single shake pack to try and see if they will like it before buying in bulk. We would love to continue the conversation and see how else we can help - we weren't able to locate an order with your name but if you reach out to us at [email protected] we'll do our best to help you!

Literally cannot even force myself to drink this sludge. Very chalky and terrible aftertaste that I cannot put my finger on. Leads me to believe all previous online reviews were paid for. $55 down the drain. Like previous reviewer (Susan), same experience. Did all preliminary research. Please save yourself the money- this meal replacer is disgusting.

Hi there, Our shakes are crafted in small batches for freshness and nutrition. Based on customer feedback and in collaboration with a team of nutritionists, we are continuously improving our recipe to maximize nutrition for all types of diets. We have forwarded your feedback to our product team and released an updated version of both our flavors earlier this year. We would love to hear more feedback about what types of tastes you like, so that we can also take this into account with our next shake batches. Would you mind emailing us at [email protected] - your feedback will directly help shape the future of our shakes for future customers!

Update(2) After posting my honest review, Biome reached out to me and offered a refund of the unopened package without making me return it. They also explained again that because this is a food product, even if the individual packets aren’t open but the main package is opened they can not accept it for return, which makes sense. Update: customer service informed me that not only can the package not be opened, but that it can only be returned to the Germany facility, so if you live in the U.S., the postage will cost about half of the refund you will receive. Original review: I researched this product for a while, read reviews and looked up ingredients and finally made a purchase. I received my order timely and I made my first shake today... the taste was not for me at all. I found the texture to be very gritty (and thats after blending it in a Ninja) it has an overly sweet flavor. So, I have requested to return the unopened bag as well as the other 14 packets(comes in a bag containing 15 packets and I purchased two bags) however, in reading deeper into the return policy it states they will only take back unopened packs in the original shipping box. So beware, once you open it you are stuck with it. It would be nice if they could come out with a “sample” size portion for purchase so that you could try it out before diving into a more expensive version but I am assuming the shipping cost would not make that economical.
