WorKs quite well!

As a 75 year old still playing basketball, I would tend to get leg cramps after the game - especially in my sleep. My doctor suggested magnesium/potassium pills. After taking these daily -- and twice on my basketball days -- I have not had a cramp since. They are easy to swallow too.

Potassium and magnesium are two vital elements that are closely related to each other. A lack of one of them can lead to a shortage of the other. Each of these elements has its own antagonist: potassium opposes sodium, and magnesium opposes calcium. Potassium plays a key role in maintaining the water-electrolyte balance, regulating pressure and conducting nerve impulses. It is the main intracellular electrolyte, while sodium is the main extracellular one. The content of potassium and sodium in the body is inversely proportional: with an increase in sodium, the content of potassium in the body decreases, and vice versa. Excellent quality, good ingredients and Fast delivery.

this formula has helped me a lot

Potassium is an important electrolyte that our bodies cannot produce, so we have to get it ourselves. This can be achieved to some extent through diet – it is found in foods such as bananas, citrus fruits, spinach, potatoes, sweet potatoes, tomatoes, dried apricots, beans, peas, almonds and dairy products, but I am not able to get my daily intake from food. I struggle with high blood pressure and this formula has helped me a lot

This is one of the best vitamin C supplements I've tried! The absorption is noticeably better thanks to the liposomal form, and it's very gentle on the stomach—no discomfort or acidity at all. I felt a clear boost in my immunity after just a few days of use. The antioxidant benefits are real, and I love that it's high quality with clean ingredients. The taste is surprisingly pleasant, and the individual packets are super convenient for travel. Great mg dosage and well thought-out package size. Highly recommend!|

Vital supplements as we get older

I had a potassium deficiency which showed up as leg cramps in the middle of the night. That’s no longer an issue, because I take one of these every day.

Nutricost Potassium + Magnesium 240 Caps

Magnesium is essential for roughly 300 body functions, and yet somewhere around 60% of Americans are deficient in magnesium. Not good. Potassium is an important mineral that many people aren’t getting enough of either. It plays a crucial role in blood pressure control and kidney function. It stops my muscle cramps dead in their track. Nutricost Potassium + Magnesium is good value and the right dosage. Wish the product had a higher dosage of Magnesium.

Acceptable Convenient Supplement

Not the highest dose but acceptable convenient supplement. Nice to have around and take daily. Importantly not an nasty Oxide form of Magnesium.

I’ve been taking this Vitamin C supplement from iHerb for a few weeks now, and I’m really impressed with the quality. The potency feels just right — not too strong but effective enough to support daily needs. The size of the capsules is easy to swallow, and the dosage per serving makes it simple to follow without confusion. I’ve noticed real benefits for my immune system, and I appreciate the added antioxidants, which give an extra boost for overall wellness. The taste is mild with no unpleasant aftertaste, which is a big plus compared to other brands. The effect has been noticeable — I feel less fatigued and more energetic throughout the day. The package is sturdy and well-sealed, keeping the product fresh. I like that the formula is suitable for a wide range of ages, making it a versatile option for the family. The ingredients are clean and clearly listed, which gives me confidence in what I’m taking. Overall, a great Vitamin C supplement that balances effectiveness with convenience!
