When I’m looking to purchase a supplement I want to look at all the details of the products.

Therefore, in this post, I looked at prices, ingredients, and different forms of electrolytes. I even priced out the servings of each electrolyte.

Most of the comparisons will be shown in tables for easy viewing.

Near the end of this article, I also have a discount code for you, if you choose one of the brands.

Different Forms of Electrolytes

Name Magnesium Potassium Sodium Calcium
Re-Lyte Hydration Malate & Glycinate Citrate Redmond’s Pink Real Salt Carbonate
Ultima Citrate Aspartate Sodium Chloride Ascorbate
This table looks at the different forms of electrolytes from each brand.

The top 3 electrolytes you will hear that we need most in keto are sodium, potassium, and magnesium. We must replenish these with food or through a supplement.

On a side note, most Americans are not getting enough magnesium in their diets.

The Difference between Potassium Aspartate and Potassium Citrate

Potassium citrate is used to stop kidney stones that can happen if someone has gout. It’s also used to treat kidney stones. Potassium citrate also alkalizes urine (source).

Potassium aspartate may increase mineral levels in your body, however, there is no solid research on this (source). It has been shown to have positive effects on brain pressure after a traumatic event to the brain (source).

The Difference between Magnesium Glycinate and Malate and Citrate

Magnesium glycinate has been found to help those who are dealing with cardiovascular diseases, inflammatory diseases, and diabetes. It even helps the quality of sleep and neurological functions (source).

Magnesium malate has been found to help the following conditions, Alzheimer’s disease, type 2 diabetes, osteoporosis, headaches and migraines, fibromyalgia, and other related conditions (source).

Magnesium citrate is easy to obtain and relatively inexpensive. This one also may help with sleep. If you consume too much of this form you will experience loose stool though (source).

All of these forms of magnesium are easily absorbed.

The Difference Between Calcium Carbonate and Calcium Ascorbate

Calcium Carbonate proves beneficial in boosting the calcium levels within our bodies. Furthermore, its utilization extends to aiding in conditions arising from excessive stomach acid production. (source).

Calcium ascorbate is a form of vitamin C with calcium in it (source 1) (source 2). It is also utilized for addressing vitamin C deficiency and supporting growth and overall well-being (source 3).

Re-Lyte Hydration $41.99 60 $0.70
Ultima $44.99 (1) 90 $0.50

What are the benefits of Redmond Re-Lyte?

One benefit of Redmond’s Re-Lyte is that it’s formulated with experts to include a 2:1 sodium-to-potassium ratio, plus magnesium, chloride, calcium, and the 60+ trace minerals from Real Salt. (The Unflavored variety does not have calcium.)

Another great benefit of Redmond’s Re-Lyte Hydration mix is that it’s easier to mix compared to their previous Re-Lyte Electrolyte powder.

The new formula has the same amounts of electrolytes, 0 carbs per serving, and still no junk with great flavor.

Are There Single-Serve Sticks for Re-Lyte Hydration and Ultima?

Yes, there are single-serve packets for both of these brands.

Why I Like Re-Lyte Hydration More than Ultima

  • I would rather consume the form of magnesium in Relyte compared to the kind in Ultima. I don’t want to run the risk of pooping my pants. HA
  • I also like the form of potassium in Redmond’s, citrate, compared to Ultima’s, aspartate, for my needs.
  • There is more potassium and sodium in Re-Lyte Hydration, which can be hard for me to get in every day.
  • I love the source of the sodium that Redmond Real Salt uses, as there are extra minerals in there. Plus it tastes better than sodium chloride.
