LMNT electrolytes

Sodium is an essential nutrient for hydration, performance, and energy. Did you know when you restrict dietary sodium, your body enters a sodium-retention mode whereby hormones spike to help your kidneys retain sodium causing a rise in blood pressure.

This science-backed ratio allows you to get enough of these vital minerals without throwing off your body’s very particular electrolyte balance and is great for hydration while traveling, in the gym, at home and at work!

Electrolytes

Sodium in LMNT

Each stick pack of LMNT contains 1,000 mg of sodium. Sodium is an essential mineral — the stuff of life — and many folks need more than they think. There are several reasons for this:

To replace heavy sodium losses through sweat. Athletes can lose several grams of sodium when training, particularly in hot, humid climates. We’ve talked to professional athletes’ trainers and they often log up to a 10-gram sodium loss in a hard practice or game.
To balance diets lacking in sodium. Processed foods contribute about 70% of US Americans’ sodium intake. When you ditch processed foods in favor of a healthy Paleo or whole foods diet, you significantly reduce your sodium intake.
To increase sodium intake on diets which cause rapid sodium loss:
1. Low-carb diets (especially ketogenic diets) minimize the body’s production of insulin. Consequently, your kidneys excrete sodium at an increased rate.
2. Fasting minimizes insulin similarly to low-carb diets, causing rapid urinary loss of sodium. In addition, you don’t consume any sodium via food during a fast.
To help people reach a baseline of 4–6 grams of sodium per day.

Athletes and folks on low-carb diets may need more sodium, but isn’t salt bad for your heart? The truth is, that’s not nearly as cut and dry as it’s been made out to be. Our 4–6 gram target comes from a 2011 JAMA study which found that 4–6 grams of sodium per day was the sweet spot for minimizing heart attack and stroke risk. To be clear, that’s a starting point. Folks with any of the aforementioned diet and lifestyle factors often need more.

Magnesium in LMNT

Each stick pack of LMNT contains 60 mg magnesium.

Magnesium is a crucial mineral. It aids in energy production, DNA repair, muscle synthesis, restful sleep, and many other things we care about, yet up to 30% of the population may be deficient in magnesium. This is likely why we see positive effects from magnesium supplementation on sleep, strength, anxiety, and depression.

Anthropological evidence suggests that our ancestors consumed about 600 mg of magnesium per day. Between 400–600 mg seems to be a reasonable target for optimal health, and there’s no downside to shooting for the upper end of that range. Try to get there with magnesium-rich whole foods first, then supplement your shortfall.

Potassium in LMNT

Each stick pack of LMNT contains 200 mg of potassium, which is ⅕ of LMNT’s sodium content (1 gram). This 5:1 sodium-to-potassium ratio is important – let’s geek out on why now.

The sodium-potassium pump is a life-sustaining protein pump in our neurons’ cell membranes. For every 3 sodium ions it releases, it takes in 2 potassium ions — a process which enables everything from muscle contraction to neuronal firing. To help our pump function optimally, our total sodium and potassium intake should reflect this 3:2 ratio.

Because athletes, low-carbers, and intermittent fasters alike incur greater sodium losses, and because minimally processed foods are naturally low in sodium, sodium tends to be the bigger issue. To account for this, LMNT was intentionally formulated with a 5:1 sodium-to-potassium ratio. It puts us in a better position to hit the 3:2 sodium-potassium pump ratio.

While we could have put more potassium in LMNT, we find it’s ideal to consume potassium mostly through diet. Yes, diets low in carbs are often low in potassium-rich foods like fruit and potatoes, and more potassium is lost through urine on keto. But eating plenty of foods like meat, avocados, spinach, etc. should get even ketogenic dieters most of the way to the sodium-potassium pump ratio (3:2).

Potassium is also an issue for people eating a plant-poor Standard American Diet (SAD). The SAD is why only 20–40% of Americans achieve the daily adequate intake set by the National Academy of Medicine (3.4 grams for men and 2.6 grams for women). And that’s just adequate. The evidence for higher intakes (between 3.5–5 grams per day) being optimal is strong, especially for potassium reducing blood pressure.
