What Hypromellose Capsule (Cellulose Capsule) is, and what it does.

Does it work
It's the container. You're not taking it for health benefits.
How much to take
Not applicable. Take whatever's inside the capsule.
Time to feel it
The shell wets and splits open in the stomach within minutes of swallowing. It's the container rather than an active, so any onset you notice comes from the powder inside.
The first dose
You swallow it and within minutes the shell wets, softens and splits, letting the powder out. The shell material itself carries on through without being absorbed.
With regular use
Nothing accumulates. Human enzymes don't break this polymer down, so week after week it does the same single job of holding the fill until the stomach opens it.
How well tolerated
Well tolerated. FDA GRAS. Used in millions of products worldwide.
How it feels
You don't feel the capsule. You feel what's inside it.
The overlooked benefit
Cellulose shells hold less water than gelatin ones, which suits powders that pull in moisture and fills that would soften a gelatin shell from the inside.

The proof, claim by claim.

These words describe the research, not the molecule's worth. Research strength is how much work stands behind one claim, and it is never a product score.

  • Reliable drug delivery vehicle
  • Equivalent to gelatin capsules for absorption

Questions people ask about Hypromellose Capsule (Cellulose Capsule).

Is this better than gelatin capsules?
For vegetarians/vegans, yes. For absorption and function, they're essentially equivalent.
Does it dissolve as fast as gelatin?
Very close. Gelatin may dissolve slightly faster in some conditions, but the difference is clinically irrelevant.
Can I open these capsules?
Usually yes. Pull the two halves apart and pour the powder into water or food. Check if the supplement has specific instructions though.
What's the capsule made from?
Plant cellulose that's been chemically modified to dissolve in water. Think of it as processed plant fiber.
