Supplement for indigestion
Betaine HCl with Pepsin:
This supplemental approach addresses the lack of stomach acid which is said to cause acid reflux in many cases. One study in 6 people with low levels of stomach acid showed that taking 1500 mg of betaine HCl increased stomach acidity [i].
B Vitamins, including folate, riboflavin, and vitamin B6, may help acid reflux. B vitamins may be linked to a lower risk of complications caused by acid reflux. They may also relieve heartburn symptoms when paired with other compounds, but more research is needed [ii].
Also eating foods high in calcium and B vitamins to help reduce reflux symptoms. These foods include almonds, whole grains, beans, spinach and kale.
Probiotics play a key role in gut health and immune function. Probiotic use can be beneficial for GERD symptoms, such as regurgitation and heartburn [iii]. YourGut Restore
Ginger is often used to soothe stomach upset and treat issues like nausea and indigestion[iv]. In studies, ginger was seen to improve several symptoms of indigestion, including stomach pain, burping and feelings of fullness[v].
Testing options for indigestion
It may be pertinent to test for an infection known as H. Pylori if symptoms persist, as symptoms of reflux can cross over with those of H. Pylori. It is recommended you speak to your GP if this is a concern for you. Testing for H. Pylori is as follows:
- A urea breath test – you'll be given a drink containing urea (a chemical that's broken down by H. pylori) and your breath is then checked after.
- A stool antigen test – a small stool sample is tested for the bacteria.
- A blood test – a sample of your blood is tested for antibodies to the H.
If your indigestion symptoms are serious and constant, or you relate to any other following please contact your doctor immediately:
- vomit that is bloody or looks like coffee grounds
- unexplained weight loss
- black stools
- trouble swallowing
