The problem with a lot of these over-the-counter liquids is that they contain emulsifiers to prevent them from separating (so they look good in the bottle!), and those are hard to digest. Taking pills is the worst thing for ulcers and reflux and other stomach issues, because they are so difficult to digest. They really work on irritating the stomach, and if you only absorb a portion of them (because of the fillers and coatings used to form the shapes and have them pop out of the mold during mass manufacture), you don't know how much of the medication you are actually taking in. I've worked with so many people whose stomach and intestinal problems were made worse - ulcerative colitis, for example. You need to work on healing the tissues, not inflaming or aggravating them even more, but it's not an overnight fix. I can help you with this but you have to have realistic expectations - there's a lot of damage and irritation in there.
And don't just consume "natural" potions from the "health food" store. You have no idea where they were manufactured (not where the distributor is located, where it's MADE), what quality ingredients are in there, whether what they say on the label is really in the container, whether there's been any testing for contaminants and purity, whether the ingredients are genetically modified, whether there's any clinical data or any study on the ingredients' efficacy and safety, or whether there's any reputable Chief Scientific Officer on staff. A lot of people get into plenty of trouble taking "all natural" or "organic" remedies because they assume they are completely safe in any dosage. They aren't. And the college kid working at the store, or even the manager, doesn't necessarily know anything - the job is to sell you something, anything. If you don't like one item, they have 20 others to sell you, and either way they make money.
In general, a single nutrient is ineffective in solving problems - your body is complex and requires a balance of nutrients and vitamins, minerals, trace elements, herbs, etc. Your body can't do much with a single (or a handful) of things. And medications are designed to treat the SYMPTOM, not the CAUSE. That doesn't mean there's no place for medications - it means you need to look at the whole problem and realize what meds can and cannot do, and also evaluate whether the side effects make things worse or put you at risk.
