Potassium and electrolytes

Of all the nutrients, potassium is the hardest to hit. At the recommended intake of 4.7g, you'll need to eat 8-11 bananas everyday to reach the daily dose. USDA electrolyte recommendations are 2.3g sodium, 4.7g potassium and 3.6g chloride. Looking at my nutrient tracking over 2 weeks, I average 1.4g of potassium a day without supplements. Here are some sources of potassium:

Estimates of potassium in certain foods¹

Food	Serving size	Potassium amount (milligrams)
Cooked spinach	1 cup	840 mg
Sweet potato	1 medium	695 mg
Plain nonfat yogurt	8 ounces	579 mg
Banana	1 cup	540 mg
Cooked broccoli	1 cup	460 mg
Tomato	1 cup	430 mg
Fat-free milk	8 ounces	380 mg
Chicken meat	100 grams	256 mg
Oats	0.5 cup (45g)	193 mg
Whey Protein	1 scoop (30g)	145 mg

Supplementing Potassium

Potassium chloride tastes horrendous. I'm currently looking at replacing it with potassium gluconate or citrate, which are better absorbed that the chloride compound.
Heres a discussion on potassium at DIY soylent: http://discourse.soylent.me/sources-for-potassium

Below table shows the amount of elemental potassium in each compound.

Potassium Compound	Potassium per gram
Potassium Chloride	521 mg (remaining is chloride)
Potassium Citrate	360 mg (remaining is citric acid)
Potassium Gluconate	155 mg (remaining is glucose)

Potassium citrate is harder to find in pure powder form so I'll probably mix potassium chloride and gluconate to get my recommended dose of electrolytes. Ill update the exact amounts once I'm happy with the combination.

Keeping sodium-potassium ratio around 3:2 (in moles) is more important since that is required for neural activity (lessons from Sol from Khan academy and brain basics). There is a also a thread on the DIY soylent forum about sodium-potassium.
