Most nutrients are absorbed in the upper two parts of the small intestine: duodenum and jejunum.
Nutrients that can be absorbed in the ileum.
- Water (most of water is absorbed in the ileum)
- Vitamins B9, B12, C, D and K
There is also a very complex timeline associated with assimilation.
* CBD assimilation takes place AFTER exposure to bile chemistry in the large intestine. So, it’s not only where in the intestine assimilation takes place, but also when (i.e., after exposure to bile chemistry).
