Yes, Mike is right, we use BioSil liquid. It tastes awful, like licking some undersea creature. It is one of the worst tasting things we take - and we take a lot of liquids, infusions and tinctures.
Dr Klinghart recommends it for detoxifying aluminum which is the main reason we take it. Neither of us have significant joint problems (well a little cracking for me).
The liquid is a little thick and sticky, so I don't drop it in the glass with the tinctures because I feel that it will simply adhere to the sides of the glass. I drop it onto a small spoon and take it that way. But we take it at the same time as the infusions/tinctures.
