Collagen is the most abundant protein in your entire body. Skin, joints, tendons, gut lining, bones, blood vessels. It's the structural scaffold that holds everything together.

And your body starts producing less of it from around age 25.

By your forties, production has dropped significantly. By your sixties, it's fallen off a cliff. Skin wrinkles. Joints ache. Gut problems appear. Tendons weaken. It's not just cosmetic — it's structural failure happening slowly across your entire body.

Here's what most people don't realise. Your gut lining is heavily dependent on collagen. When it breaks down, you get increased intestinal permeability — leaky gut. Undigested food particles and toxins slip into your bloodstream, triggering immune reactions and chronic inflammation.

The published research on supplemental collagen is strong, and my training confirms it. Improved skin elasticity within four to eight weeks. Reduced joint pain. Better gut barrier function.

But form matters. You want hydrolysed collagen peptides — broken down into small fragments your body can actually absorb. Whole collagen molecules are too large and pass through without being utilised.

Types I and III are most important for skin, gut, and structural support. Type II is more specific to cartilage and joints.

10 to 15 grams daily. Mix it into water, coffee, or a smoothie. Tasteless and dissolves easily. Timing doesn't matter. Consistency does.

Your body can't rebuild what it's losing if you don't give it the raw material.

Collagen repairs the gut lining structurally. But your blood sugar and metabolism are just as critical to how fast you age. Ask me about berberine next. Researchers are calling it nature's metformin — and the data is hard to ignore.
