Good value for money

Potassium is an essential electrolyte mineral, and the recommended daily intake is around 4,500 mg. However, most people consume less than this through food and supplements. I’ve tried many forms of potassium compounds, and this one is new for me. Compared to potassium citrate, I can already notice some differences. The capsules are a bit large, and the powder doesn’t completely fill them. They really should use smaller capsules.

The capsules are easy to swallow, and I have no doubt about the quality—the manufacturer is reputable and uses only high-quality ingredients. The vitamins have a pleasant, non-irritating taste. They strengthen the immune system, improve brain function, and maintain beautiful skin and hair. I recommend these vitamins to anyone who wants to maintain their health and feel in shape!

More benefits

The ingredients are potassium minerals based on glycine, which is from animal skin. It is said to be easier to absorb. I personally take it in the evening because glycine protein can help with sleep. However, if some people have frequent nocturia, it is not suitable for nighttime use.
