Hrdgain I think the powder is a freeze drying process where they spray the mct's with milk proteins. So they are "encapsulated". I don't know how subject to degradation they are...I'm thinking of keeping mine in the fridge.
One teaspoon (5 grams) of mine equals 35 calories. They do contain a small amount of carbohydrates, though.
Just happened upon this searching mct + ketogenic:

This is a site, I think, that is concerned with ketogenic diets as medical interventions. Epileptics...
I just got the mct's for the hell of it, btw. Calories.
