Finally! My answer to adult acne and digestive problems!
For the past couple of years I had been struggling with both digestive issues like bloating and gas after meals and acne breakouts on my back and the back of my neck.  I was trying everything to clear up my skin- healthy diets, green tea, drinking/showering with filtered walter, anti-fungal treatments, benzoyl peroxide, a doxycycline Rx from the dermatologist (if unsuccessful, next up was accutane- AHH!).  My prayers were answered when I came across an interview with Chris Kesser, who mentioned that adult acne including digestive issues is often attributed to low stomach acid.  So I went ahead and bought NOW's betaine HCL capsules.  (I remembered reading years ago about the gut-skin axis and that any permanent cure to common skin issues had to begin with the gut.)  Amazingly, I did notice immediate improvements with my skin, but I was having trouble finding the correct maintenance dose while doing the HCL challenge.  After several days, the HCL was causing more bloating than I was experiencing before. Stopped taking the HCL, and have been taking 2 tsp of bitters every day for the past four days.  My neck and back are still clearing up and my digestion has not been this great in months, maybe a year.  Also, I feel more comfortable taking a digestive aid that helps train the stomach to produce its own acid, among other benefits for digestion.  It's still early, but I think finally have found something that works!
