Vitamin’s Physical State And Solubility are Two Different Things.

Posted On : March 29, 2014
One of the most common misconceptions regarding vitamins is that its physical shape and state (liquid versus solid) defines its solubility.  Water-soluble vitamins may be found in dry powder form (solid) or may be a form of liquid.  Fat-soluble vitamins may also be found in both solid and liquid form.  It is important to appreciate that one cannot assume that if a fat soluble vitamin is in liquid form in a gel cap it will be absorbed.  What makes a fat-soluble vitamin absorbable is not its liquid, physical state, but rather it’s molecular structure, which makes it possible to be absorbed.  When purchasing vitamins that are fat-soluble, labels such as “dry”, “water-soluble” are indications that it is water-soluble more important than its shape, size or the nature of the vitamin itself.
A liquid form of vitamin A and D may be less soluble than a dry powder form.  This is because it dry powder form may be chemically structured so that it is soluble in water versus a liquid form that is not.  An analogy will be the mixing of olive oil (liquid) with vinegar (liquid).  Olive oil will stay separated because it is not water-soluble even though it’s a liquid state.
