Lipid-Based Delivery Systems
A comparison of the main lipid-based technologies used to improve absorption, stability, and effectiveness of bioactive longevity compounds. Delivery matters as much as dose.
What this is
Comparison guide for lipid delivery technologies — liposomes, phytosomes, NLCs, and LNPs — and when each improves bioavailability.
Why it matters
Premium brands charge more for liposomal labels that may not improve absorption. Delivery chemistry determines whether dose dollars work.
What to do next
Match your compound to phytosome or NLC rows, then verify branded forms at Protocol Shop before buying.
TNiC approach: For most longevity and cellular resilience compounds, Phytosomes and NLCs offer the best balance of performance, stability, and real-world applicability. We evaluate delivery technology when curating product picks in the Protocol Shop.
Liposomes
- Strengths
- • Good absorption
- • Versatile — works with many compound classes
- • Biocompatible, long safety record
- Limitations
- • Moderate stability; quality varies by manufacturer
- • Phospholipid shell can degrade without proper storage
- Best Suited For
- Vitamins C & D, glutathione, general polyphenols, curcumin
- Maturity
- High
- Widely available, most consumer supplements
Phytosomes
- Strengths
- • Strong covalent bond with plant compounds
- • Multiple clinical trials with measured outcomes
- • Good stability — phospholipid-polyphenol complex resists oxidation
- Limitations
- • Mainly effective with specific polyphenols
- • Less versatile for non-plant molecules
- Best Suited For
- Curcumin (Meriva), resveratrol, silymarin (Siliphos), EGCG
- Maturity
- High
- Well-established branded extracts with clinical backing
NLCs
Nanostructured Lipid Carriers
- Strengths
- • Superior stability vs liposomes
- • High drug loading capacity
- • Controlled-release kinetics
- • Strong bioavailability gains for fat-soluble compounds
- Limitations
- • More complex to manufacture
- • Fewer consumer products at scale yet
- Best Suited For
- Sulforaphane, fisetin, quercetin, resveratrol, curcumin
- Maturity
- Medium-High
- Growing rapidly in premium supplement lines
Modern LNPs
Ionizable Lipid Nanoparticles
- Strengths
- • Excellent endosomal escape
- • Very high delivery efficiency for nucleic acids
- Limitations
- • Complex and expensive to manufacture
- • Higher potential for immune activation
- • Often over-engineered relative to supplement needs
- Best Suited For
- mRNA / siRNA delivery, pharmaceutical applications (e.g. mRNA vaccines)
- Maturity
- Low in supplements
- Primarily pharmaceutical — not commonly used in consumer supplements
