If the pH of your small intestine is abnormal, it can harm you. Your intestines, liver, etc. can not assimilate important vitamins, minerals and food supplements when the pH is higher or lower. If the pH has too little alkaline, for example, it cannot heal itself, leaving open internal and external wounds for extended periods of time until alkaline is restored, which is difficult to do.
Because it is the ideal pH for enzymes in intestine to work
The pH of the small intestine is approxmiatly 8.
The pH of the small intestine is roughly pH 8. It is slightly alkaline, as this is the alkalinity which best suits digestive enzymes.
Pepsin becomes inactive when it reaches the small intestine where the pH is between 7 and 9. It functions best when in an acidic environment like the stomach.
The pH of the jejunum, which is a part of the small intestine, is typically slightly alkaline and ranges from 7 to 8. This alkaline pH environment helps to optimize enzymatic activity and nutrient absorption in the small intestine.

its usually about 2-3 I believe the pH to be around pH 6-6.5 for the duodenum. The pH of the stomach is 1-3 so 2-3 is still in the stomach. The small intestine is anywhere between 6-8 as the pancreas dumps bicarbonate in.
The duodenum releases bicarbonate-rich pancreatic juice to neutralize the acidic chyme coming from the stomach. This helps raise the pH of the chyme in preparation for digestion by enzymes in the small intestine.
The pH levels in the stomach and small intestine play a crucial role in digestion. In the stomach, the acidic pH helps break down food and kill harmful bacteria. In the small intestine, the pH becomes more neutral to allow enzymes to work effectively in breaking down nutrients for absorption. Overall, maintaining the right pH levels is essential for proper digestion to occur.

The saliva need to be gentle enough at 7 pH to make foods small enough to swallow safely. The stomach needs to have strong acidity, at a 1 or 2 pH, to break down proteins into amino acids. The small intestine is where almost all of the absorption of the smaller portions are absorbed into the blood. The normal pH of the blood is close to 7 so the pH of the small intestine is 7.4.
Sodium bicarbonate is released into the small intestine to neutralize the acidic chyme coming from the stomach, creating a more optimal pH environment for digestion and absorption of nutrients in the small intestine.
