Aspartame-One of the fastest ways to lower pH that has been discovered is with fake sugars. The best lowest acidic one is Aspartame. It does have some side effects. it may cause a headache.. this means to cut back. You can find Aspartame at Walmart in there drink mixed called Great Value sugar free. This has been found to be the best drink mix because it lowers pH the best. If you can not find this then others have found that crystal lite works for them. You should try to drink 66-100 oz of this drink mix every day

Folic Acid (450 mcg a day)** you can take more of this if needed and be safe!! Take all the time THIS DOES NOT SWAY! IT PREVENTS BIRTHDEFECTS AND PREVENTS MC
Cranberry- (total of 1,500 to 10,000 mg fresh fruit equivalent a day if possible. This is based on equal to fresh fruit equivalent.. not amount on bottle. This part can be tricky. So, 10,000 ml equivalent to fresh fruit) take from af to O (stop at O) this is taken to lower pH side effect: cranberry can not be taken after O as it can cause mc. Cranberry is a blood thinner so if you already taking a blood thinner do not take this.
