### ⭐⭐⭐⭐⭐ Tound my missing link
*by J***E on December 28, 2025*

Helped get rid of my 5 year struggle with bad breath in 2 days despite brushing my teeth twice a day, helped with stomach and intestinal pain, helped with acne, joint pain, muscle recovery, muscle cramping after intense workouts helped with low blood pressure. I am an athlete so I sweat a lot and just found out I had hypokalemia because of depleted low potassium levels. I take 1 one in the morning 1 at night. Potassium had been my missing link. Also bought their Magnesium CitaMate and take them at the same time.
