Herbalists have traditionally used bitter herbs to promote increased acid in the stomach.
There are many different bitter herbs. You could start with Agrimony.
I suggest, purchase dried Agrimony, make a herbal infusion (herbal tea), and drink it before each meal. You can make enough in the morning for the whole day, and keep it refrigerated. Don't use Agrimony capsules, as you need to taste it for it to promote increased acid in the stomach.
Agrimony is also beneficial for leaky gut syndrome, while not all bitter herbs are. So it is also beneficial for anyone with food allergies .
I could make many more comments. For example:
Do you know that your stomach is too alkaline?
I suggest you don't take hydrochloric acid, as it can do damage on the way to the stomach.
You don't want to acidify your entire GI tract, only your stomach.
You mentioned in another post that you have eczema. Diet, lifestyle, and herbs can be used to completely eliminate eczema.
You sound discouraged as nobody has responded previously. Different people have gone to different schools of learning, and have knowledge in different areas. Some don't know the answer to your question. But they may have good knowledge in other areas. Also some people are busy, and may have responded when they have time.
Cheer up. You can have a great life. The world is not going to end anytime soon.
Keep learning. Life is a continual learning experience. When you have dealt with this challenge, you can learn how to deal with the next one.
