Keto Electrolytes Powder – Fresh Lemon 200g

Hi, I looked through the page but I cannot find how to use this powder... One scoop a day? Are two acceptable (morning and evening)? Can I sprinkle it over my salad? Can I dissolve it in water, orange juice, tomato juice? Is hot soup OK? Is it true, that on the day of using this powder I mustn't drink green tea?
