A one of a kind product!! resB has helped tremendously with my breathing and digestion. I have tried other probiotics in the past, but nothing has compared to this. The website is very user friendly, and the customer service is always top notch!
I’ve suffered from allergies in the past, and I work around allergens every day. Since I started taking ResB, every day has been enjoyable! I don’t have to worry about waking in the morning with a stuffy nose or watery eyes. I feel like I can breathe easier, as well as keep my stamina up during my workouts. I also suffered some long term respiratory effects from Covid-19 which ResB has really helped to improve! I could go on and on about how my quality of life has improved! This supplement is a must, you will not be disappointed in the improvement of your respiratory health!
I've suffered with sinus issues for the most part of my life and this product has truly been amazing. Not only have I been able to stop constantly using a netty pot, but I've also been able to lessen the use of medications that just leave me feeling terrible throughout the day. While placing my first order I made a mistake entering my address and customer service was so friendly and on top of it immediately. I thought the mistake would delay my order, but I still received it very quickly!
Recently, I contracted Covid 19. My doctor prescribed an antibiotic and breathing treatment. I was recovering however, after a week, I experienced a persistent cough. Thankfully, resB Lung Support was advised. The cough quickly subsided. I will keep a supply of resB Lung Support in my refrigerator. I highly recommend.
I have a hard time remembering to take supplement products, but my allergies had been so bad the last few weeks, I had to commit. I'm a week in and already feeling the difference. And I switched from my usual probiotic - it's definitely helping my digestion as well!
Would love to see more products, like maybe one for sleep!
Absolutely amazing probiotic. The blend of bacteria and herbs is a wonderful novelty and this product works very well. My digestion and bowel movements were better in the first few days. I can run longer and exercise capacity has increased in 2 months of use. Skin is also better and I think it’s because of the antioxidant in the product. I have recommended this to several of my friends who have had similar benefits. Overall, the best one stop supplement for gut, lung, immune and skin health.
None
This is the best probiotic supplement on the market, and I can't be convinced otherwise. I've taken other probiotics in the past, and none have had the same positive effects. I noticed the gut benefits almost instantly, and the lung and immune health benefits are a GREAT addition. The packaging, website, and customer service also get an A+!
