The 50 Top-Rated Potassium Supplements to Reduce Muscle Cramps and Aid Hydration

The health benefits of potassium can’t be understated. Maintaining healthy levels can help your body with everything from preventing muscle cramps to stabilizing your blood sugar. You can reduce your anxiety or re-hydrate your body after a big workout, or even help control your blood pressure by getting enough potassium each day through your diet or with the help of supplements.

Potassium deficiency in your body may cause nausea, heart palpitations, cramping, or overall fatigue. Despite the benefits, it’s actually rather difficult to achieve 100% of your recommended daily value for potassium. You’ll still have to make sure you’re monitoring your diet – even with most supplements – because over-the-counter vitamins typically don’t contain large portions of potassium. As always, when starting a new vitamin or supplement, check with your doctor to make sure that whatever supplements you choose to take are safe for you and won’t have an impact on other medications you may be taking.

We’ve found 50 top-rated potassium supplements to help you make a smarter buying decision and compiled them alphabetically below. Ratings are based on Amazon reviews and are current at the time of this publication.

6. Douglas Laboratories – Potassium 99 mg Chelated

Douglas Laboratories - Potassium 99 mg Chelated

Current Rating: 4.0

Potassium is chelated when it is bonded with a larger substance (in this case a potassium amino acid), and when the larger molecule is digested in the body, the potassium is released.

11. Good State Liquid Ionic Potassium

Good State Liquid Ionic Potassium

Current Rating: 4.1

Because potassium overdoses are dangerous (although not common) the FDA has regulated all over-the-counter supplements to contain a maximum of 99 mg per serving. Which means, like this product, there is not a nice round number for the dosage. While some reviewers suggest disregarding the FDA guideline, it’s important to talk to your doctor. Until you do so, using this is strictly for supplementing your already balanced diet.

iOSAT Potassium Iodide Tablets

Current Rating: 4.6

This may seem a bit doomsday to put on our list, but if it comes up in a Potassium search and has had almost 700 people reviewing it, we think it’s worth a mention. Potassium iodide can be used for those with an iodine deficiency – particularly those with too little seafood in their diet – but that is rare. The bulk of the people who purchase this use it for what it’s marketed for: a safety net for radiation. If you live near a nuclear plant or base; you fear nuclear war; or just worry about a radiation emergency, this is your FDA-approved pill. If you take this pill after such an emergency, health officials say it may prevent thyroid cancer that may be caused by radiation. It’s not a daily supplement, but it’s a safeguard you can take.
