Ingredient science
Your turmeric pill is mostly not curcumin.
Turmeric root is only a few percent curcuminoids by weight — and most supplements are just ground turmeric root. Here's what's actually going on, and why how you deliver curcumin matters as much as how much you take.

Overview
Turmeric, curcumin, curcuminoids — what's the difference?
You've seen turmeric everywhere — golden lattes, capsules on every shelf, a spice your grandmother probably cooked with. It's reasonable to assume a turmeric supplement is a curcumin supplement. Here's what's actually going on.
Turmeric is the root. Curcuminoids are the active compounds inside it — curcumin, demethoxycurcumin, and bisdemethoxycurcumin — and curcumin is the most studied of the three. The catch: turmeric root is only about 2-5% curcuminoids by weight. The other 95%-plus is starch, fiber, and oils.
That matters because most turmeric supplements are exactly that — dried, ground turmeric root powder. So a big-sounding turmeric dose still carries only a sliver of actual curcuminoids. A standardized curcumin extract is different: it concentrates the curcuminoids up to around 95%.
And then there's the second problem. Even pure curcumin is famously hard to absorb — it's poorly water-soluble, breaks down in the gut, and clears quickly. So two things have to go right, not one: how much curcuminoid is in the bottle, and how much of it your body can actually use.
“Two things have to go right: how much curcumin is in the bottle, and how much of it you actually absorb.”
The big comparison
Turmeric root vs. standard pills vs. liposomal.
Most comparisons stop at one number. This one shows both that matter — how concentrated the curcuminoids are, and how much actually gets absorbed — plus what you're really left with when you multiply the two.
Standard turmeric pills
Effective curcumin delivered
Minimal
Curcuminoid content~3-5%
Relative absorptionLow
- Usually just dried turmeric root powder in a capsule
- Still only a few percent curcuminoids
- Curcumin's poor absorption (~1-2%) is left unsolved
Manna Liposomal Curcumin+
Effective curcumin delivered
High
Curcuminoid content95%
Relative absorptionHigh
- Standardized 95% curcuminoid extract — concentration solved
- Phospholipid liposomal delivery — absorption solved
- No black pepper needed as a workaround
Curcuminoid content of turmeric root is commonly cited at roughly 2-5% by weight; standard turmeric-powder supplements reflect that. "Standardized extract" concentrates curcuminoids to about 95%. Absorption and "effective delivered" figures are illustrative of the well-documented difference between unformulated and liposomal curcumin, not a specific clinical measurement. These statements have not been evaluated by the FDA.
Why delivery works
How a liposome carries curcumin.
Curcumin's biggest weakness — it's fat-soluble and fragile — is exactly what liposomal delivery is built for. A liposome is a microscopic bubble made of the same phospholipids as your own cell membranes, and curcumin tucks neatly into its wall.

How it works
The trip curcumin has to survive
Swallowed
Every dose starts whole.
Two doses of the same nutrient go in. One is unprotected; one is wrapped in a phospholipid shell.

What the numbers say
The absorption gap, drawn out.
Bioavailability is the share of a dose that reaches circulation. For standard curcumin it's strikingly low — often cited in the low single digits of a percent. Liposomal delivery is designed to lift that curve and hold it higher for longer.
Liposomal Standard
What matters: the exact multiplier depends on the formulation, dose, and study — and human outcome trials (does more absorption change how you feel?) are still developing. The chart below shows the shape of the difference, not a specific clinical result.
What the research shows
The honest state of the evidence.
Here's what's well-established about curcumin and curcuminoids, and where things are still developing. Every source is linked so you can read it yourself.
The concentration gap
Turmeric root is only a few percent curcuminoids
This is well-documented: the curcuminoids that drive curcumin research make up only a small fraction of turmeric root by weight. It's why standardized extracts exist — and why a turmeric-powder pill and a curcumin extract are not the same product.
The absorption gap
Standard curcumin is poorly absorbed
Also settled. Reviews of curcumin pharmacokinetics consistently describe low oral bioavailability — driven by poor solubility, rapid breakdown, and fast clearance. It's the reason delivery technology exists for this ingredient at all.
The fix
Liposomal delivery raises curcumin absorption
Across formulation reviews and pharmacokinetic studies, wrapping curcumin in phospholipids or liposomes increases how much reaches the bloodstream versus standard curcumin. A randomized human study of a phospholipid-decorated liposomal curcumin reported a large jump in plasma curcumin and a longer half-life.
The biology
Why curcumin is studied in the first place
Curcumin is researched for its role in the body's normal inflammatory and antioxidant pathways — for example, its interaction with the NF-κB signaling pathway. This is mechanism research; it is not a claim that any supplement treats a condition.
Where the science is headed
Better absorption, with more to learn
The core win is clear: getting more curcumin into the bloodstream is well-supported, and a standardized, liposomal product addresses both the concentration and absorption problems at once. What's still being mapped is how reliably that translates to specific outcomes — promising work that's simply ongoing.
Our approachSee Liposomal Curcumin+
The bigger pictureHow Manna builds curcumin.
Practically, this is why Liposomal Curcumin+ starts with a standardized 95% curcuminoid extract — solving the concentration problem — and then wraps it in a phospholipid liposomal system to solve the absorption problem. Two fixes for two distinct issues.
We're not here to promise an outcome or recommend a dose — that's a conversation for your clinician. We're here to make sure neither concentration nor delivery is the reason a good ingredient underperforms.
Liposomal Encapsulation
Curcumin is one example of a nutrient that needs better delivery — but the same idea applies across the cabinet. See how liposomal encapsulation works for nutrients in general.
