Generally speaking, you can mix H.V.M.N. Ketone Ester with another beverage. H.V.M.N. Ketone Ester will not become any less effective when mixed with another drink. 

For maximum performance, H.V.M.N. Ketone Ester is designed to be consumed all at once, so if diluting the 65mL (25g ketone ester) with another liquid means you'll be consuming it over a longer period of time, that may impact how effective it is.
