Newly reformulated, the Keto Chow Fasting Drops are designed specifically for fasting with higher levels of sodium and less potassium so that kidney patients can use them. 

Fasting Drops are available in three sizes:

  1. The small "Pocket Flask" with enough concentrate for 2.5 gallons of water at the recommended dosage.
  2. The large 250ml/8.3 oz "Refill" size with enough concentrate for 25 gallons of water, plus it also includes a free empty Pocket Flask bottle! It's 3x the price for 10x the stuff.
  3. The super big 550ml/18.6 oz "Big Refill" size with enough concentrate for 56 gallons of water at the recommended dosage. Does NOT come with an empty pocket flask. Compared to the small pocket flask, it's 5 2/3x the price for 22 1/3 the stuff.

The sea water concentrate used in Electrolyte Drops are from Utah's Great Salt Lake and are Generally Recognized As Safe (GRAS) and comply with applicable standards for heavy metals from the U.S. F.C.C.

  • NO sugars, calories, caffeine or artificial ingredients
  • Safe for hydration packs. Will not stain or leave a residue
  • Allows for flexible dosing - at recommended dose, most do not detect any flavor, those doing fasting will often do 3-4x dose.

For those sensitive to the mineral flavor, add lemon or lime juice. For the best tasting electrolyte water, use good quality water and mix thoroughly.

Picking the right Keto Chow Electrolyte Supplement

We have 3 different Electrolyte Supplements:

  • Electrolyte Drops: a balanced mix of Sodium, Potassium, and Magnesium (along with other trace minerals).
  • Mag Drops: concentrated Magnesium with some Sodium and Potassium (along with other trace minerals).
  • Fasting Drops: High levels of Sodium with some Magnesium and small traces of Potassium (along with other trace minerals).

How to measure Fasting Drops

The lid of the pocket flask doubles as a measuring device, the full lid is 1/2 teaspoon (2.46ml) and will give you the amounts shown on the label. If you use a full cap in 32oz/1 liter of water, you likely will not be able to taste any difference. You are quite welcome to use double or even more if you find the taste acceptable or desirable.

Lid Measuring

How much should you use?

When fasting, we recommend you get at least:

  • 3000-6000 mg per day of Sodium
  • 400+ mg per day of quality Magnesium

6 Teaspoons (12 caps) of Fasting Drops will cover these amounts. Use fasting drops when you feel like you need more electrolytes. Around here we use it in all our water throughout the day while we're fasting and some of us use double the recommended dosage because we like the salt.

I’m sure they work for others

I could not get past the taste. Even one packet in 32 oz of water was too much for me.

Fasting is much more comfortable now!

I was having a lot of trouble using salt when I fasted. I HATED the salt water! GAG! Also, I never knew whether I was using too much or too little...and I still got cramps. I tried other methods, and finally tried these drops and I love them. I put two drops in every 8 oz of liquid I drink (more if I do a heavier/longer) exercise. I also use 2 drops of the Magnesium drops in the same 8 oz of liquid. No more salty water--it just tastes like regular water to me now. I feel SO much better. I should mention I use these drops every day, not just on my fasting days. I fast three days per week and my eating days are keto...I highly recommend these drops. EASY and they work!

Yes, I really like them!!

I have trouble doing extended fasts even though I have been doing intermittent fasting for close to a year. Dr. Berry recommended these and I didn't want to try "another electrolyte" supplement especially if it was going to contain sugar. Well, fast forward a couple months and now I see a Keto Chow ad. I fell in love with the ad and decided to give them a try along with a couple of their Keto Chow samples. I was able to complete my fast with ease and I use them every day. It makes my water "wetter", if you know what I mean so I tend to use more than the recommended amount. And best part is there is no sweeteners to worry about. :)

Love them!

I could not get my electrolytes dialed in right until I started using this product. This product helped me to successfully conquer my daily leg cramps! The packaging is great and it even comes with a handy travel size container.

Keto Chow is complete nutrition for Nutritional Ketosis. It's a drink mix that quickly and easily makes a complete keto meal. It's not meant to replace your bacon and steak.

Rather, it's targeted to replace the mundane meals; running to a meeting, breakfast in the car, stuck in class, etc...

By design, a serving of Keto Chow provides 1/3 of your daily needs of electrolytes, vitamins, protein and more. The aim is that you could replace all your meals without ill effect if you are so inclined, but most users replace 1-2 meals a day and have a fantastic keto meal with family or friends for the 3rd. It's also quite tasty with a range of great flavors.

You combine the powdered mix with your own personal amount of heavy cream (and water) to get the calories you want, anywhere from 800 calories a day, up to 5000 calories. Many liken the taste and texture to melted ice cream or a milkshake. The full-flavored mixture of Keto Chow does contain whey protein and artificial sweeteners; if those are a concern for you there's also a "Base Powder" option that has the electrolytes and vitamins but not the flavor/protein/sweetener. You can mix our base powder with a protein powder and sweetener of your choice. Want easy, complete nutrition give Keto Chow a try! People love Keto Chow over on Reddit! (which is saying a lot =) Check out This review, or this one, or this review. You can also search Reddit for "Keto Chow" or "KetoChow" - both sorted so the newest posts are always at the top.

⚠ WARNING: This product can expose you to lead, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to

Information on the above warning: Keto Chow and Heavy Metal Exposure (Proposition 65 warning)

The short version: The Keto Chow shakes have an almost immeasurable amount of lead (if a product has plants in it - like spices for flavor - the plants pick up traces of lead) - but that level is over the line that California has decided could potentially cause birth defects... if you consume 1000x the amount that requires a warning. So a warning to California residents is required by law (as you see above).

Longer version: For any unaware, California has a fun citizen's initiative commonly referred to as "Proposition 65" or "Prop 65" - it's the reason many consumer products have a warning that "this product contains chemical known to cause cancer in California" (or similar) which is generally followed by everyone thinking "good thing I'm not in California!" I'll not get into the validity of the "No Significant Risk Levels" and "Maximum Allowable Dose Levels" established as part of Prop 65, they are what they are, and if a company sells something to a resident of California, a California resident (usually a lawyer) has the ability to sue if there is not a warning and the product contains levels of heavy metals or other contaminants higher than the levels established. I can say that the heavy metal levels in Proposition 65 are low enough that coffee shops have had to post warnings and Disneyland has warnings in their picnic area. Keto Chow was served a notice that "Safe Products for Californians" intends to sue Keto Chow for not having warnings that Keto Chow contains heavy metals, specifically lead. The tactic being that many of the levels defined by Proposition 65 are so absurdly low that quite literally EVERYTHING has enough lead to qualify for needing a warning. Also, since Keto Chow contains protein, and the 'cool' thing to do these days is use plant protein which tends to be from China and contains a lot of heavy metals, logically Keto Chow will contain heavy metals (like Soylent™ does). The thing is: we don't use plant protein, instead we only use protein created by sustainable mobile bioreactors (ruminants); in fact, very few of the ingredients come from plants and the animals don't absorb heavy metals. Due to the lawsuit, we paid for an independent lab to test for heavy metals in Keto Chow, the complaint was only for "Lead and Lead Compounds" but we went ahead and had Arsenic, Cadmium, Lead, and Mercury tested. The test has a minimum measurable level of 0.01 mg/kg of material, and each meal of Keto Chow is around 44-50g of powder. Here are the measured levels of heavy metals in Keto Chow, the serving size, and what your exposure is compared to the allowed levels with one caveat: the cadmium level is only established for inhalation, if you ingest it orally there is not established level. Lead is interesting, Proposition 65 establishes a "No Significant Risk Levels" for causing cancer set at 0.015 mg or 15 micrograms per day. Lead also has a "Maximum Allowable Dose Levels" (MADL) for causing reproductive harm of 0.0005 mg or 0.5 micrograms per day. The MADL is set by looking at the level that no observable effect occurs and dividing that by 1000. In other words, if a toxin causes an effect at 10 units, the MADL would be defined at 0.01 units; meaning that the dose where lead will cause reproductive harm is 0.5 mg or 500 micrograms per day. I guess it's surprising that many of the flavors of Keto Chow do NOT contain enough lead to require a warning label. Notably, the ones with the highest levels are those that contain spices or other plant-derived flavorings.

Chocolate and Mocha both contain cocoa powder, a plant product, and both have the highest levels of heavy metals on the list; though the levels are still far below the very low bar set by Proposition 65 to necessitate a warning for cancer. The threshold for needing a "reproductive harm" warning is 0.00050 mg - as a precaution against future litigation we just went ahead and put the warning up for everything.
