What is Liposomal D3?
Liposomal D3 is a bulk ingredient in which vitamin D3 (cholecalciferol) is encapsulated within a phospholipid vesicle matrix. The liposomal delivery system is produced using Herbosomal® — Bionutricia’s proprietary liposomal encapsulation and sustained-release technology (registered trademark; patent-pending PI2023005773) — which is a manufacturing capability offered for ingredients where a brand owner or formulator wants a liposomal delivery format for their finished product.
Bionutricia supplies this as a bulk ingredient for B2B formulation; brand owners and manufacturers formulate it into their chosen finished format. Approved OEM output formats include powder sachets, liquid sachets, gel sachets, pouch beverages, chewable tablets and liquid bottles.
How the liposomal delivery system is described
The phospholipid matrix encloses the vitamin D3 payload within lipid vesicles. The phospholipids used are supplied from non-GMO sunflower lecithin, which is soy-free. The encapsulation process is a manufacturing technology — it describes how the ingredient is produced, not a clinical claim about absorption or efficacy. Bionutricia does not make unsupported bioavailability or enhanced-absorption claims about this ingredient.
What vitamin D3 is and why it matters
Vitamin D3 (cholecalciferol) is a fat-soluble vitamin that plays a role in calcium absorption and bone health, and is also recognised for its function in immune system regulation. It is one of the forms of vitamin D used in food fortification and dietary supplementation. The established nutritional role of vitamin D3 in calcium homeostasis and bone health is recognised in food science and regulatory frameworks — this is the general function of the vitamin as a dietary nutrient, not a therapeutic claim about this specific ingredient.
Format, packaging and specification
Liposomal D3 is supplied as a bulk powder for B2B formulation. Buyers should request and agree the following specification parameters before placing a bulk order:
- Vitamin D3 assay per gram — request the certificate of analysis showing the cholecalciferol assay value and analytical method for the specific lot.
- Phospholipid content — confirm the phospholipid identity (sunflower lecithin) and phospholipid percentage on the CoA.
- Particle size and solubility — relevant for dispersion in liquid or powder formulations.
- Moisture and water activity — for shelf stability and packaging selection.
- Microbiology limits — total plate count, yeast and mould, coliforms and pathogen screening per lot.
- Clean-label declarations — vegan, non-GMO, soy-free, gluten-free and allergen status in writing.
- Halal certification — JAKIM Halal certificate on the ingredient, not just the facility.
- Shelf life and storage conditions — confirm recommended storage temperature and shelf life on the CoA or product data sheet.
