Of course, companies who produce in liquid form are more than happy to self advertise these facts. The process requires state of the art technology and can be a bit expensive, which is why the supplements do indeed cost more than their pill counterparts. Reducing the substances to liquid forms allows the body to be able to digest it faster and easier than pill form, which results in a higher percentage of the substance being used by the body due to the increased biochemical potency and this results in more effect for less substance.
The system works since liquid hoodia is pre-extracted and therefore the body does not actually need to digest and break down the hoodia as it would need to in the pill. Rather, liquid form contains pre-extracted hoodia and this allows the body to use it as soon as it is consumed, bypassing the digestive process.
Obviously price can be a deterrent in swaying certain buyers from switching to liquid form, however there are a couple more advantages. Namely, less hoodia has to be consumed for similar effect. Rather than having to take a bulky pill, users can instead put a few drops into a glass of water and drink the extract with ease. Thankfully, the taste is of such liquids is usually either not noticeable or contains a few additives to add a good taste to counteract any negative tastes resulting from the extracts in the liquid.
