What customers say
Customers generally appreciate the potassium supplement for its quality, effectiveness, and value. Many users report improvements in overall health, well-being, and specific benefits like supporting heart health, fluid balance, and bone health. The product is praised for its clean ingredients, good packaging, and convenient size. However, some customers find the dosage low at 99mg and mention difficulty swallowing the tablets due to their size and shape. Despite these minor issues, the supplement is highly recommended by many for maintaining proper potassium levels.

Potassium is essential for the functioning of the nervous system and muscles. It also stimulates insulin secretion, controls blood pressure and regulates kidney function and the body's water balance. So it is worth supplementing our diet with potassium.

Great Buy
Verified purchase
I have been advised by my doctor to take potassium supplement which I have done in the past couple of years. I recently tried this Nature’s Bounty and like that the size of the caplet is much smaller than what I used to take. It’s easier to swallow and I don’t have to drink a lot of water. The price is reasonable and I like see-thru bottle.

I'm so happy I bought this - I could definitely feel a difference after using it. This is one of my top go-to brands that I know and trust. The quality and performance never disappoint, and it's a good size for the price. Smells fine and the packaging is good. Will definitely buy this again!

They work well.
Verified purchase
These are a bit difficult to take, as they are caplets rather than capsules. The consistency has a powdery feel to it, I will say they do their due diligence, the effect would be more efficient if it's combined with another supplement. I enjoy taking Potassium and Zinc, or with Magnesium. Do some research on what is best to take at the same time, not just for safety but also effectiveness.

The real thing
Verified purchase
I take potassium at bedtime to avoid morning headaches. 2 caplets of 99mg do the job. This Nature's Bounty formula does the job, and is easy to swallow. This tastes like potassium, unlike many of the potassium powder, pills, and capsules I have tried. Now I can regulate my intake with more knowledge of how much I am taking.
