When a person takes Fountain of Life by placing it under their tongue, the extract is absorbed sublingually.
This means that FOL is quickly absorbed in to our bloodstream and in the blood plasma, it is converted to enterolactone, which is a mammalian lignan. Without this conversion, the human body cannot utilize the antioxidant.
When we ingest Fountain of Life, it is absorbed in our small intestine and goes through the same process. What makes our lignan efficient compared to flaxseed is the fact that flaxseed has to be cleaved in the small bowel before it is absorbed. Due to this extra step, it is sometimes not absorbed to its fullest.
As some people will place FOL in gelatin capsules, there is no change in efficacy, assuming that their digestive system is not compromised. If they can digest the capsule, they will still receive the same benefits as placing it under their tongue.
