Remember what we said earlier — you’re not what you eat, you’re what you absorb? Let’s dive a little deeper into that idea.
Your small intestine isn’t just a long tube. It’s an incredibly advanced absorption machine. And its secret weapon?
Surface area!
The inside of your gut is covered in millions of tiny finger-like projections called villi, and each of those is covered in microvilli — even smaller projections that form what’s called the brush border.
This intricate structure increases your intestinal surface area to roughly the size of a tennis court — all to maximize how much you can absorb from your food.
If your gut lining is inflamed or damaged (from stress, processed foods, antibiotics, or illness), these villi and microvilli can flatten, shrink, or even break apart.
That means:
This is where nucleotides come in.
They help your body regenerate intestinal cells, repair the brush border, and restore full surface area — giving your gut its absorptive power back.
More surface area = more absorption = more nourishment = better health.
It’s about what happens after the bite — at the microscopic level.
Protecting and healing your gut lining means protecting your whole body.
That’s the power of understanding — and supporting — your surface area.
