Just recently I noticed a little more fatigue than normal and thought ah, the potassium link and again realizing the RDA for women daily is 5100mg, one has to eat a lot of potassium rich foods to get near there....So what I'm going to do for a while is take 2-99mg tabs with several meals/snacks daily and see how I feel.
The link I'm posting mentions 8 signs of potassium deficiency and one listed is Stiffness and my damaged knee is sure stiff, maybe more potassium will loosen it up.
8 Signs and Symptoms of Potassium Deficiency (Hypokalemia)
I'm also drinking a glass of low sodium V8 with a bit of water dilution but not every day as it's so filling. A glass contains about 800mg potassium.
The supplement I'm using is potassium gluconate.
Don't overdo it, but don't underdo potassium.
I've eliminated bananas as I believe they are overrated for what we get, and higher in carbs and sugar.
Since I posted this link I've made it to 81.
