Quick Answer
A genuine liposomal supplement names its phospholipid source (like phosphatidylcholine), has an appropriate particle size (roughly 50–200 nanometers), is third-party tested, and makes realistic absorption claims. Avoid products that rely on the word "liposomal" alone or advertise implausible "100× absorption" figures.
The quality checklist
- Named phospholipid source. Look for a specific phospholipid such as phosphatidylcholine — not just the word "liposomal."
- Appropriate particle size. Functional liposomes generally fall in the 50–200 nanometer range; outside that, a real delivery mechanism is doubtful.
- Third-party testing. Independent verification that the active is actually encapsulated, not merely mixed alongside empty vesicles.
- Realistic claims. "100× absorption" banners are a warning sign. Genuine oral-study data shows meaningful but modest improvements, not miracles.
- Oral, not IV, data. Be wary of absorption figures borrowed from intravenous pharmaceutical liposomes — a different context from an oral supplement.
- Storage honesty. Many genuine liquid liposomal products require refrigeration and have shorter shelf lives; shelf-stable claims deserve scrutiny.
The bottom line: "liposomal" on a label is a claim, not a guarantee. The details — phospholipid source, particle size, testing, realistic numbers — separate a genuine delivery system from label theater. And remember it's worth paying for only where the nutrient is genuinely hard to absorb.

Related Questions
How can I tell if a liposomal supplement is real?
Look for a named phospholipid, disclosed particle size (50–200nm), third-party testing, and realistic absorption claims from oral studies. Vague products that only say 'liposomal' warrant skepticism.
Are refrigerated liposomal products better?
Many genuine liquid liposomes are relatively fragile and benefit from refrigeration. A shelf-stable liquid 'liposomal' claim isn't automatically fake, but it's worth checking how the product supports it.
