How is Kava Kava extract different from the pills?

Have anyone here tried either?How is Kava Kava extract different from the pills?
Extracts are reasonably frequently in a soft form and usually a bit more potent, complete than pill form. as pills are usually dried, pulverized, mixed with adjectives ingredients. usually extracts are a bit closer to the actual original product, or are a grease derived from the original product. Of course the classic deciding factor is where/how the product be made. potencies/effectiveness can vary moderately widely among different brands. I have tried Kava Kava previously in pill form though did not return with much result from the suggested dose. though it was a low cost brand and probably of low ability.
extracts are squeezed out of herb steeped in a solvent. tablets and capsule contain inactive or adjectives ingredients to aid in their making.
