I've had capsules, but I hadn't tried shilajit resin before, so I wasn't sure what to expect. This is a deep black-brown resin with a pungent smoky, earthy smell. Ideally, one mixes the resin into a beverage to drink. I've found that the easiest way for me to take the resin is in hot water, like a tea. The flavor like this reminds me a lot of Lapsang Souchong smoked tea. It's not my favorite, but it's easy to get it down.
While some supplements are not recommended to be taken with hot water, as it decreased efficacy, shilajit is just fine hot or cold. However you take it, just know the taste is also pretty powerful. I don't want to say it's disgusting, because it isn't. It's just a bit of a shock to a western palate.
I've been taking shilajit for a while in capsule form, and have noticed a difference in my mobility and cognition (I have MS). While this resin concentrate I'm sure would work similarly, I do think I'll probably stick with the capsules for convenience.
