Title says it all. I'm looking for serious electrolyte powder, drink, supplement, DIY that is GLUTEN FREE. For when water isn't hydrating enough due to an underlying medical condition Celiac disease. I hope this is OK to post. I can easily drink 1.5 gallons a day and gain no relief from horrible dehydration. I'll also share my water bottle soon as I can!
I will look into molasses. I've tried fruit squeezes like lemon, limes, grapefruit, watermelon juice, cucumbers, and others. Doesn't cut it for my needs. I deal with like super dehydration. It can onset rapidly with my health conditions.
Fruit juice has vitamins and other micronutrients, but it doesn't necessarily have that elemental salt profile.
Blackstrap is the good stuff, it's got potassium, calcium, magnesium, sodium, iron. Because of how it is produced, it has lots of the impurities of the sugar concentrated in it. Sorghum molasses is okay but not as good for this as blackstrap is. Take a look at the nutrition facts, and you'll see a bunch of quantities for stuff that's on the periodic table. I suspect various other concentrates might have similar properties.
Typically I add maybe 20g molasses per liter of water, with another 10g of iodized salt or baking soda or cream of tartar (potassium hydrogen tartrate).
I had a health condition for a while that had me carrying salt water on my person for a year, just as a precaution.
