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.

It's always good to have bloodwork done on potassium levels, my levels always comes in on low end of range. I've found lately when I take 200-300 mg (2-3 tabs) I am much more energized when I wake -up after's night of good sleep, and when I skip this dose, I feel like I was run over by a Mack truck in the morning. So I'm doing the before bed dose.

I know I don't get the RDA of potassium daily.

Do your due diligence on this subject.

Please check first with your Doctor if you're going to take Potassium supplements. Some people can not deal with it. mrsD's post above talks about some of that.

Bringing this up again, one of my favorite health topics. And remember the general RDA for potassium as I mentioned above, I just don't believe I get that in my foods, so I supplement. If I could drink low sodium V8 a lot during the day it would make a nice difference, I know when I drink one glass I feel energized instantly.

Always good to discuss with qualified MD, many are not I've found in my life. I have done my own research on it all for decades and yes it's good to get a lab done on potassium and even if in the range, one can be in low end and have a lot of issues from low potassium. I make sure my magnesium intake is adequate also.
