What is liposomal vitamin C

L-ascorbic acid encapsulated in phospholipid bilayer · bypasses intestinal SVCT1 saturation · reaches suprafisiological plasma concentrations via oral route.

Vitamin C (ascorbic acid) is an essential cofactor · humans don't synthesize it (GULO mutation ~63 mYa). Roles: collagen hydroxylases cofactor (prolyl-hydroxylase, lysyl-hydroxylase) · neurotransmitter hydroxylase cofactor (dopamine-β-hydroxylase) · non-enzymatic regenerator of GSH and vit E · intestinal Fe absorption cofactor · intracellular antioxidant and immune modulator (phagocyte + T-lymphocyte function).

The classic oral C problem: saturable intestinal SVCT1 transporter at ~200 mg/dose · doses >500 mg lose efficiency (much urinary excretion, dose-dependent osmotic diarrhea). Liposomal encapsulation (Davis 2016, LivOn) bypasses SVCT1: phospholipid capsules pass to the liver via intestinal lymphatic system · delivers 8-10x more to plasma than free ascorbic acid. Hickey-Saul-Levy demonstrated that 5 g liposomal oral matches plasma concentration of 50 g IV.

«Liposomal vitamin C achieves plasma concentrations that approach those of intravenous administration · oral 5 g lipo equals 50 g IV in peak plasma concentration · this opens therapeutic windows previously only achievable via hospital infusion.» Steve Hickey · The Vitamin C Foundation · J Nutr Med 2008

Vit C dose · how much, when and how

4-phase protocol · liposomal bypasses SVCT1 · IV doses reserved for hospital · general prevention and common cold prophylaxis.

Phase 1Baseline maintenance

Longevity nutrition dose

500-1,000 mg liposomal/day (1 morning dose)

Healthy adult · collagen + general antioxidant coverage. Take morning fasted or with breakfast. Liposomal is room-temperature stable · refrigerate after opening.

Phase 2Preventive immune support

Active dose

1,000 mg × 2-3/day (2-3 g total)

Flu season, travel, high stress, athletes. Mason 2023 endothelium + Hemilä common cold meta dose. Maintain temporary 2-8 weeks. Avoid pre-sleep (mildly stimulating).

Phase 3Acute illness

Therapeutic pulse

1,000-2,000 mg every 2-4h × 24-48h

Cold/flu onset · mild ambulatory sepsis. High frequent doses until resolution (Hemilä 2023 +18% duration shortening). Return to baseline post.

Phase 4Oncology coadjuvant

IV under doctor

25-100 g vit C IV × 2-3/week

Only under specialized integrative oncology. Schoenfeld 2023 glioblastoma · selective pro-oxidant tumor effect. NEVER self-medicate IV. Liposomal does NOT substitute high-dose IV oncology.

Liposomal vs Ascorbic acid vs Ester-C · which to choose

3 forms with radically different bioavailability · canon 2026 pro liposomal · common ascorbic for low dose · Ester-C more marketing than science.

Vit C interactions · precaution contexts

Specific cases · high safety profile but attention to chronic high doses and specific diseases.

Consult healthcare professional if
  • Hemochromatosis or iron overload: Vit C increases heme and non-heme Fe absorption · contraindicated in Fe overload. If supplementing Fe, space 4h or avoid high C doses. Functional hematology →
  • Severe G6PD deficiency: high IV doses can cause hemolysis in G6PD-deficient. Screen G6PD before IV protocol (not applicable to oral).
  • Recurrent oxalate kidney stones: vit C metabolizes to oxalate · doses >3 g/d chronic can increase urinary oxalate. Pause/limit 1 g/d if oxalate stone history. Abundant hydration. Functional nephrology →
  • Active chemotherapy: complex debate · vit C antioxidant may interfere with ROS-dependent chemo. High-dose IV vit C has specific adjuvant evidence (Schoenfeld 2023). Only under integrative oncology.
  • Warfarin anticoagulants: high doses reduce warfarin effect · monitor INR if chronic. DOACs unaffected.

Liposomal Vit C frequently asked questions

8 real questions · answers based on Davis + Hickey + CITRIS-ALI literature.

Liposomal or common ascorbic acid?
Liposomal if you want doses >500 mg without diarrhea + max bioavailability (Davis 2016 ~10x). Common ascorbic works for baseline 200-500 mg/d doses at low cost. For pro wellness protocol: liposomal.
Does it equate to IV?
At small doses (1-5 g): almost yes (Hickey-Levy). High-dose oncological IV (25-100 g) can't be replicated orally. Lipo covers 90% of ambulatory IV indications (cold, immune, endothelium).
How long until I notice effects?
Immune prophylaxis: subjective acute (days). Endothelium (FMD): 12 weeks (Mason 2023). Skin collagen: 8-12 weeks. General cofactor: chronic background effect. Cold: shortens duration 8-18% (Hemilä).
Morning or evening?
Morning or morning + midday. Capsules mildly stimulating (similar to caffeine-free tea). Pre-sleep can affect latency in some subjects. Last dose <15h.
Does it cause kidney stones?
Chronic doses >3 g/d can raise urinary oxalate · risk in oxalate stone history. Abundant hydration (3+ L/d) prevents it. Doses <2 g/d without documented risk.
Pregnancy and lactation?
Yes · RDA increases 85-120 mg/d gestation/lactation. High chronic doses (>2 g/d): pause voluntarily unless obstetrician indicates. Liposomal safe at standard doses.
What about the Vit C and cancer debate?
High-dose IV (Schoenfeld 2023 glioblastoma) has specific adjuvant evidence · selective pro-oxidant tumor effect. Oral doesn't replicate. Only under specialized integrative oncology. Dietary Vit C + moderate supplementation WITHOUT risk.
Better liquid sachet or capsule?
Liquid sachet (LivOn) has the most documented bioavailability evidence. Dry liposomal capsules valid but less data. Soapy lipo taste is the cost · take with citrus juice to mask.
