Ok. Yes you want to try to get the pink himalayan salt or sea salt for the minerals. If you can't get the potassium citrate powder from amazon you can try "lite salt" or "nu salt" which is half salt and half potassium. Here's what it looks like https://www.amazon.com/Morton-Salt-Lite-Less-Sodium/dp/B004AY43D2.
I actually use LITE SALT.(because it's on amazon) I put 2 - 2 1/2 teaspoons per liter of water. 2 liters of water per day. LITE SALT has a pretty good ratio of potassium to sodium. https://www.amazon.com/Morton-Salt-Lite-Less-Sodium/dp/B004AY43D2/ref=sr_1_3_a_it?ie=UTF8&qid=1521640112&sr=8-3&keywords=lite+salt
Mushrooms, get some lite salt or nu salt. They have A LOT of potassium per sodium so you get both. You really need to up your electrolytes or you will have a bad time. I recommend Lite salt. On 1/4 TSP goes a long way for electrolytes. See below for an example.
That's actually one of the best I've seen per serving but Morton's Lite Salt is a lot cheaper (only $2-3 in just about every grocery store I've been in or about $7 on Amazon) and has similar sodium/potassium content. Would need to go elsewhere for magnesium, though.
The major electrolytes you have to worry about with keto is sodium, potassium and magnesium. Sodium is easy to get through salt. Most people drink bone broth to get more salt. I'm not a fan. If you're in the US, potassium supplements are heavily regulated and pretty much useless the best option is to buy Lite Salt or No-Salt which are either a 50/50 mix of salt and potassium chloride or will be pure potassium chloride. I buy big bags of magnesium citrate on amazon.
For me, supplementing 400mg magnesium, ~2g of potassium, and 3-4g of sodium on top of what I got through food was the sweet spot.
You may find it gross, but I actually liked buying powerade Zeros and mixing in lite salt and magnesium citrate. Just make sure you start off with lower doses of magnesium supplements and work your way up, while at home, to find where you need to be. You'll know if you get too much when the diarrhea kicks in. :)
No, the main ingredient is salt, it just has some other stuff as well. https://www.amazon.com/Morton-Salt-Lite-Less-Sodium/dp/B004AY43D2/ref=sr_1_3_a_it?ie=UTF8&qid=1523646457&sr=8-3&keywords=lite+salt
Lite salt is awesome: https://www.amazon.com/Morton-Salt-Lite-Less-Sodium/dp/B004AY43D2/
How do you supplement electrolytes? Recently I've been taking a 1/4 tspn of salt lite for every meal skipped.
Sure can! Looks like this.
Try this one--it has potassium, sodium and magnesium all-in-one (tastes better too): https://www.amazon.com/gp/product/B004AY43D2/ref=oh_aui_detailpage_o01_s01?ie=UTF8&psc=1
I think Amazon will ship it to Europe - http://www.amazon.com/Morton-mixture-sodium-table-11-oz/dp/B004AY43D2/
