Capsule vs. Tablet: The Thrilling Story of Glue, Chalk and Varnish

Or: Why your supplement shouldn’t be built like a patio slab.

Picture this. You have a lovely, effective active ingredient: a fine powder from nature, full of potential. What do you do with it?

Option A: Put it in a capsule. Done. Have a coffee.

Option B: Turn it into a tablet. That’s where the fun starts.

The tablet: a small feat of engineering (unfortunately)
Powder doesn’t want to be a tablet. It has no ambition to be hard, round and smooth. So you have to persuade it, with a few helpers:

Binders, so the whole thing holds together. Basically glue, but food-grade.
Fillers, because a sensible dose of active ingredient is often too small to make a decent tablet. So you pad it out, a bit like the free bread before your main course.
Flow agents and lubricants, so the powder doesn’t stick in the machine. Magnesium stearate sends its regards.
Disintegrants, so the thing you just pressed under several tonnes of pressure falls apart again in your stomach. Yes, really. First you compress it, then you add something to undo the compressing. Peak efficiency.
Coating, so it slides down your throat, looks shiny and doesn’t taste like what’s inside. A small varnish job for your gut.
The result is a sturdy little piece of industrial engineering. Sometimes it’s so sturdy that you start wondering whether it’s a supplement or a building material.

The capsule: almost embarrassingly simple
Capsule open. Powder in. Capsule shut.

That’s it. No several-tonne press, no glue, no varnish job. The shell dissolves in your stomach and the contents get to work. Very undramatic. Almost boring, if you’re into the high-tension world of excipient chemistry.

At GO PRIMAL we find that kind of boring very appealing. When a product is about what’s inside, it makes sense to cram as little else in as possible.

“But tablets are cheaper to make!”
Exactly. Thanks for bringing it up.

Tablets can be made fast, cheap and in huge quantities. That’s great for the margin, and less great if you’re the one swallowing chalk, glue and varnish every morning so the production line runs smoothly.

“And what about the ‘other’ brands?”
We’re not naming names. We don’t need to. Just turn the pack around and read the ingredient list. If, after your actual active ingredient, you’re greeted by a small chemistry kit of binders, fillers, flow agents, coatings and colourings, you know the score: you’re not only paying for what you want, you’re paying for everything needed to make it look pretty.

In fairness (we’re not monsters)
Not every tablet is the devil, and not every capsule is holy. Tablets do have their uses, for example when someone needs slow release or a very high dose. Capsules have a shell too, made from gelatine or plant-based cellulose (HPMC). Neither is magic. It’s simply the leaner packaging.

But if the goal is to get as much of the good stuff and as little of everything else as possible into your body, the answer is simple.

Conclusion
Tablet: Pressed, glued, filled, varnished. A real craftsman’s job.
Capsule: Powder in, lid on, done.

We know which one we’d pick. Spoiler: it’s the boring one.
