About a year ago I switched to a low carb diet and quickly noticed that I had great difficulty digesting proteins. The common solution appeared to be supplementing with betaine HCL as needed and gradually reducing the dose as your own stomach acid production came up to speed. What this means is that I've taken anywhere from 20 to 50g (yes, grams) of betaine HCL per day to aid in digestion, unaware of any effect the betaine might have on the whole process. Since my digestion is no better than it was a year ago, and my fatigue seems to be worsening (I had pre-existing CFS) my search for a solution has lead me here. It seems like with sufficient zinc and functioning mitochondria my stomach acid will start back up. Can the betaine groups be interrupting with proper methylation and eventual mitochondrial function? If so, is there anything I can do to speed the reversal of the 'damage'? I've stopped their use already. Also, my hair and nail growth have slowed to almost nothing and my skin regenerates very slowly. This only developed over the last ~7 months, previously regeneration and growth was rapid. Could this have something to do with the betaine overload?
