You can take the right nutrient at the right dose and still get almost nothing from it. Here's what's actually going on — and how liposomal encapsulation changes the math.

You've done the homework. You picked a compound with real research behind it, checked the dose, maybe even spent a little more for a clean label. And it's reasonable to assume that what's on the label is what reaches your bloodstream.
Often, it isn't. Many of the most useful nutrients — curcumin is the classic example — are poorly absorbed on their own. Curcumin is fat-soluble, breaks down in the gut, and gets cleared by the liver quickly. The result is that only a small fraction of a standard dose ends up circulating where your body can use it.
This is the gap delivery science tries to close. The honest answer is that the nutrient was never the bottleneck — getting it past digestion was. That's the problem liposomal encapsulation is built to solve.
A nutrient you can't absorb is a nutrient you didn't really take. The absorption is the point.
A liposome is a microscopic bubble — a sphere made of the same kind of fat molecules that build your own cell membranes. That structure is the whole trick: it's familiar to your body, and it can carry a payload tucked safely inside.
Swallowing a supplement starts a gauntlet. At each stage, an unprotected nutrient loses some of itself. Encapsulation is about getting more of the dose through that gauntlet alive.
Stomach acid and digestive enzymes break down a lot of an unprotected compound before it ever gets a chance to be absorbed. The phospholipid shell acts like a protective coat through this stretch.
This is where nutrients actually cross into the body. Fat-soluble compounds struggle here on their own. Liposomes are lipid-based, so they're built to interact with — and pass through — the intestinal lining.
Because a liposome is made of the same material as your cell membranes, it can fuse with them and release its payload directly. The delivery vehicle and the destination speak the same language.
More of the original dose ends up circulating — which is the only place a nutrient can do anything at all. That's the practical promise: less lost in transit.
Bioavailability is the share of a dose that actually reaches circulation. For standard curcumin it's strikingly low — often cited in the low single digits of a percent. Encapsulation is designed to raise that curve.

Human pharmacokinetic studies of phospholipid and liposomal curcumin formulations report meaningfully higher absorption than standard curcumin — frequently in the range of several-fold, and much higher in some formulations.
What matters: What matters: the exact multiplier depends on the formulation, the dose, and the study — and human outcome trials (does more absorption translate to how you feel?) are still genuinely preliminary. The chart below is illustrative of the shape of the difference, not a specific clinical result.
Here's what's well-established, and where things are still developing. We've linked every source so you can read it yourself.
Each dot is one finding below — the further left, the more settled the science. We placed them honestly: absorption is well-supported; downstream outcomes are still earlier-stage.
This is the settled part. Reviews of curcumin pharmacokinetics consistently describe low oral bioavailability — driven by poor water solubility, rapid breakdown, and fast clearance. It's the reason delivery technology exists for this ingredient at all.
Across formulation reviews and pharmacokinetic studies, wrapping curcumin in phospholipids or liposomes raises how much reaches the bloodstream versus standard curcumin. The size of the gain varies by formulation, but the direction is consistent.
A randomized human study of a phospholipid-decorated liposomal curcumin reported a large jump in plasma curcumin and a longer half-life versus standard curcumin. Findings like this are promising — and a reminder that results are formulation-specific.
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.
Practically, this is why Manna leads with delivery. We formulate around getting the active where it needs to go — using a phospholipid liposomal system rather than relying on absorption enhancers like black pepper, which many people find hard on the stomach.
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 the delivery side isn't the reason a good ingredient underperforms.
