Liposomal vitamin c powder bulk
Product Introduction
Liposomal Vitamin C Powder is an advanced delivery formulation of L-ascorbic acid (Vitamin C) encapsulated within phospholipid liposomes. This innovative technology overcomes the absorption limitations of standard vitamin C, which has reduced bioavailability at higher doses due to saturation of intestinal transporters. By encapsulating vitamin C within liposomes, this premium ingredient achieves superior cellular uptake, reduced gastrointestinal discomfort, and enhanced efficacy—making it the ideal choice for high-performance immune support, skin health, and antioxidant formulations.
Our Liposomal Vitamin C Powder is engineered from high-purity L-Ascorbic Acid (CAS 50-81-7, ≥99.0% purity prior to encapsulation) encapsulated within a phospholipid bilayer matrix derived from **non-GMO sunflower lecithin**. The sunflower-sourced phospholipid eliminates soy allergen concerns and satisfies clean-label requirements for the EU, North American, and Asia-Pacific markets. A carbohydrate carrier matrix (maltodextrin) is incorporated during spray drying to preserve liposomal vesicle integrity in solid-state form.
The product is a white to light yellow powder—the pale yellow hue is intrinsic to fresh lecithin, with a characteristics that are slightly citrusy and mildly acidic, neutral enough for beverage and sachet formulations.
product benefits
1. Superior Bioavailability & Cellular Uptake
Standard vitamin C absorption is limited by sodium-dependent vitamin C transporters (SVCT1/2) in the intestine, leading to reduced bioavailability at higher doses. Liposomal encapsulation bypasses these transporters, allowing vitamin C to be absorbed directly into the bloodstream and delivered to cells via fusion with cell membranes. This results in significantly higher plasma vitamin C levels and improved tissue distribution.
2. Immune System Support
Vitamin C is essential for optimal immune function, supporting the proliferation and function of lymphocytes, neutrophils, and natural killer (NK) cells. The enhanced delivery of liposomal vitamin C ensures that immune cells receive adequate ascorbate to mount effective responses against pathogens.
3. Potent Antioxidant Protection
As a water-soluble antioxidant, vitamin C neutralizes free radicals in the aqueous compartments of cells and regenerates oxidized vitamin E. The liposomal format enhances intracellular delivery, maximizing antioxidant protection in both cytoplasmic and mitochondrial compartments.
4. Collagen Synthesis & Skin Health
Vitamin C is an essential cofactor for prolyl and lysyl hydroxylases, enzymes required for collagen synthesis. Enhanced cellular delivery supports skin elasticity, wound healing, and reduction of UV-induced photodamage. Liposomal vitamin C is particularly effective in topical and oral beauty formulations.
5. Reduced Gastrointestinal Discomfort
High doses of standard vitamin C often cause diarrhea and stomach upset due to osmotic effects in the gut. Liposomal encapsulation minimizes contact with intestinal mucosa, allowing for higher doses without gastrointestinal side effects.

Electrolyte & recovery drinks — targeted at athletes with elevated oxidative stress post-exercise.
Hydration powder blends — translucent or clear formulation options adjustable by concentration.
Nutraceutical beverages— stable dispersion without pH adjustment or additional emulsifiers.
3 Cosmeceuticals & Topical Skincare
Anti-aging serums — phospholipid bilayer enables biomembrane fusion and deeper dermal penetration; nanoliposomal VC has demonstrated improved transdermal absorption and follicular accumulation in CLSM studiesPMC
Brightening & hyperpigmentation treatments — sustained tyrosinase inhibition via controlled release.
Collagen-boosting creams — cofactor for prolyl hydroxylase, stabilizing collagen triple helix.
Antioxidant & anti-pollution formulations — protected from air oxidation on-shelf and on-skin, extending active viability versus raw ascorbic acid (which degrades within days of bottling in unbuffered formulations).
Customer Success Stories
Case 1 — Premium Immune Supplement Line (North America)
Switched from standard ascorbic acid to our 80% assay liposomal powder at 1,000 mg/serving in vegetarian capsules. Reduced capsule size by 35% while maintaining the same plasma-level claim.
Post-launch customer reviews cited "no stomach upset" as the top differentiator; return rate dropped from 8% to under 2%. Product achieved Amazon's "Climate Pledge Friendly" + "Small Business" badges and passed third-party label-claim verification (ISO 17025 lab).
Case 2 — Functional Beverage Startup (EU Market)
RTD wellness shot brand, 3 SKUs, retailing in 1,200+ health-food stores
Integrated liposomal vitamin C powder into a cold-filled 60 mL shot at 500 mg/bottle. The powder's cold-mix compatibility eliminated pasteurization steps, preserving phospholipid integrity and reducing energy consumption on the production line.
Accelerated shelf-life testing confirmed 12-month stability at ambient temperature with no phase separation or vitamin C degradation below 90% label claim. Passed EU Novel Food compliance review on first submission.
Case 3 — Cosmeceutical Serum Range (Asia-Pacific)
Skincare brand specializing in evidence-based actives, sold through premium department stores and e-commerce
Replaced pure L-ascorbic acid (which required pH 3.5 formulation and caused stability issues) with liposomal vitamin C powder at 10% equivalent in a serum base. The near-neutral liposomal dispersion allowed formulation at pH 5.5, improving skin compatibility.
6-month real-time stability testing showed >95% VC retention versus 62% for the unencapsulated control. Instrumental skin testing (Mexameter) on 30 subjects showed measurable reduction in hyperpigmentation after 8 weeks.

fAQ
Q1: What is the difference between liposomal vitamin C and standard ascorbic acid powder?
A: Standard ascorbic acid has limited bioavailability at higher doses due to saturation of intestinal transporters (SVCT1/2). Liposomal vitamin C encapsulates ascorbic acid within phospholipid vesicles, bypassing transporter limitations and achieving significantly higher plasma and cellular levels. It also reduces gastrointestinal side effects common with high-dose standard vitamin C.
Q2: Is liposomal vitamin C suitable for liquid formulations?
A: Yes. Our liposomal vitamin C powder disperses readily in water and aqueous systems, making it ideal for ready-to-drink beverages, liquid supplements, and functional foods. It forms a stable liposomal suspension upon reconstitution without the need for high-shear mixing.
Q3: What is the source of the phospholipids used in the liposomal matrix?
A: We typically use sunflower lecithin (non-soy) as the phospholipid source. Soy lecithin is available upon request. Please specify your preference when placing an order.
Q4: How stable is liposomal vitamin C during shelf storage?
A: When stored under recommended conditions (cool, dry, away from light), liposomal vitamin C maintains its encapsulation integrity and ascorbic acid content for 18 months. The liposomal matrix provides additional protection against oxidation compared to standard vitamin C powder.
Q5: Do you support private labeling and custom formulation?
A: Absolutely. We provide white-label and private-label services, including custom vitamin C concentrations, proprietary liposome sizes, co-encapsulation with other actives (e.g., zinc, quercetin), and branded packaging solutions.
Q6: What is the minimum order quantity (MOQ)?
A: For R&D and formulation trials, we offer 1 kg sample packs with no minimum commitment. Standard bulk orders start at 25 kg. For custom OEM formulations (custom assay, particle size, or flavor), the MOQ is typically 100 kg per specification.
