Collagen is a protein that holds together our connective tissues.
Think of collagen the same way you would think of "Cement/mortar" holding together blocks in a building.
Without the cement motor, the building would fall apart and if the motor does not have enough cement, the building will not be strong. That's your collagen.
All our connective tissues like skin, hair, nails, joint cartilage, the inner lining of our stomach and lungs are all made up of collagen.
Types of Collagen
There are different types of collagen but the ones we need to focus on are type I, II, III, IV & IX.
Each of these types of collagen is more effective in specific areas than the other.
For example, Most collagen types will have type I, III, & IV. This is the commonest, called collagen peptides.
This type of collagen comes from hides. As you can tell, it is more specific to skin, nails, and hair.
Collagen Type 2 usually comes in caps, and it is gel-like supplement.
It is not in powder form and if a powder has collagen type II, that powder doesn't dissolve completely.
Sources of Collagen Peptides.
Sources of collagen also determine how potent collagen is. The commonest source is cowhides. It is about 90% of all collagen peptides out there in the market.
This type of collagen comes from chicken necks :-) and it has a lot of collagen Type II.
It is rarely sold alone, you will find it in multi-collagen types and usually more expensive.
This is the most potent type of collagen with salmon collagen being the best, rare, and most expensive type of collagen.
The best and the most expensive collagen comes from salmon fish bones. It is rare to find it.
It is even more expensive if it comes from wild-caught salmon fish.
