Know about Fillers
A filler is an inactive ingredient that is mixed with naltrexone in order to ensure uniform filling and dosing. Certain fillers may physically bind with the LDN which prevents its necessary rapid absorption. Here is what you should know:
- Cellulose or plant-fiber fillers are more likely to bind with the LDN and slow its absorption. They are best avoided.
- Protein-based fillers (amino acids such as glycine) do not slow down LDN absorption.
- Simple-sugar fillers such as sucrose, dextrose, or lactose do not slow down LDN absorption.
- Lactose should be avoided by individuals with lactose intolerance, gastrointestinal issues, irritable bowel syndrome (IBS), inflammatory bowel disease (IBD, such as Crohn’s and Colitis), and leaky gut syndrome.
- Propylene glycol (also known as methylethylene glycol), and glycerine are suitable for use in liquid LDN formulations.
