Plum your "supplement" sounds good! Maryb, I have been now for more than a month been taking sublingually a B Complex by Douglas Labs. You can put the capsule whole under the tongue or just the powder. It dissolves nicely in less than an hour and yes! You feel the energy boost. I also take Rojal Jelly and Panthetine sublingually, and none of these two supplements was intented to be sublingual either.
I am always interested in greater absorption, an sublingual offers and impressive improvement over oral supplementation. Supplements are too subtle in its effects for me, so sublingual is a great asset to multiply their effects.
