I know most of us get heart burn from the AAS/Cialis we take and we use PPIs such as omeprazole and it's ilk to mitigate it. Just thought I'd post this article reference up for food for thought.

(this paragraph is a copy and paste from the refenced website below)

Proton pump inhibitors (PPI) are now one of the most widely used classes of drugs. PPIs have proven to have a very favorable safety profile and it is unusual for a patient to stop these drugs because of side effects. However, increasing numbers of patients are chronically taking PPIs for gastroesophageal reflux disease and a number of other common persistent conditions, therefore the long-term potential adverse effects are receiving increasing attention. One area that is receiving much attention and generally has been poorly studied, is the long-term effects of chronic acid suppression on the absorption of vitamins and nutrients. This area has received increased attention because of the reported potential adverse effect of chronic PPI treatment leading to an increased occurrence of bone fractures. This has led to an increased examination of the effects of PPIs on calcium absorption/metabolism as well as numerous cohort, case control and prospective studies of their ability to affect bone density and cause bone fractures. In this article these studies are systematically examined, as well as the studies of the effects of chronic PPI usage on VB12, iron and magnesium absorption. In general the studies in each of thee areas have led to differing conclusions, but when examined systematically, a number of the studies are showing consistent results that support the conclusion that long-term adverse effects on these processes can have important clinical implications.
