1. Structural Identity Verification (HPLC + UV λmax 265 nm)

Batch-specific HPLC retention time and UV absorption maximum (λmax 265 nm in ethanol) confirm the pine-derived cholecalciferol is structurally identical to lanolin-derived Vitamin D3 — same CAS 67-97-0, molecular formula, and molecular weight.

2. Optical Purity & Heavy Metal Compliance

Specific rotation (+105° to +112°) confirms optical purity, while strict Heavy Metal (Pb ≤ 2 ppm) and Arsenic (As ≤ 1 ppm) limits are verified for food-grade safety.

3. HALAL, KOSHER & ISO 22000 Certification

Produced in ISO-certified facilities with full HALAL and KOSHER documentation. Nitrogen-flushed, light-protective sealed packaging is verified per batch to guarantee oxygen-free storage stability during transport.

Pine Phytosterol-Derived — Plant-Based Starting Material

Conventional Vitamin D3 is produced from lanolin cholesterol extracted from sheep wool grease. This product uses pine phytosterols as the starting material — a plant-based sterol source that undergoes chemical transformation to yield cholecalciferol that is chemically identical to the lanolin-derived molecule. The pine origin is a documented starting material choice, not a botanical extract or whole-plant preparation.

1,000,000 IU/g — Standard Commercial Potency for Oil-Phase Fortification

The 1,000,000 IU/g concentration (2.5% cholecalciferol in carrier oil) is the industry-standard working concentration for softgel encapsulation, oil-based drop manufacturing, and lipid-phase food fortification premixes. At this potency, 1 gram of oil delivers 1,000,000 IU, enabling precise microgram-per-serving dosing in finished products.

Chemically Identical to Lanolin-Derived D3 — Verified by CAS and Molecular Formula

The cholecalciferol produced from pine phytosterols has the same CAS number (67-97-0), molecular formula (C²₇H₄₄O), and molecular weight (384.64 g/mol) as lanolin-derived Vitamin D3. The structural identity is confirmed by HPLC retention time and UV absorption maximum (λmax 265 nm). The difference is the source of the starting sterol, not the chemical structure of the final molecule.

MCT Oil Carrier — Directly Compatible with Softgel and Drop Manufacturing

The pre-dissolved oil format eliminates the need for manufacturers to handle crystalline cholecalciferol, which is potent at microgram-level doses. The oil is ready for direct use in softgel filling lines, oral drop bottling, and oil-based premix blending without additional dissolution steps.

FUNCTIONAL ROLES

1. Dietary Supplements

Softgel capsules and oral liquid drops — the dominant delivery formats for Vitamin D3 in the consumer supplement market.

2. Food Fortification

Fortified milk, dairy products, margarine, edible oils, and formulated nutritional products where fat-soluble vitamin D3 addition is specified.

3. Infant Formula & Follow-On Formula

Vitamin D3 is a mandatory fortificant in infant and follow-on formula products under CODEX and national regulations.

4. Multi-Nutrient Premixes

Blended into oil-soluble multi-vitamin premix systems alongside Vitamin A, Vitamin E, and Vitamin K for use in food and supplement manufacturing.

Q1: Is pine-source Vitamin D3 chemically different from lanolin-source Vitamin D3?

A: No. The cholecalciferol molecule produced from pine phytosterols is chemically identical to that produced from lanolin cholesterol. Both products have the same CAS number (67-97-0), molecular formula (C²₇H₄₄O), and molecular weight (384.64 g/mol). The difference is the biological origin of the starting sterol material — pine phytosterols versus lanolin cholesterol — not the chemical structure of the final purified molecule.

Q2: What does 1,000,000 IU/g mean in practical terms?

A: 1,000,000 International Units per gram of oil. This corresponds to 25 milligrams of cholecalciferol per gram of oil (2.5% concentration). One IU of Vitamin D3 is defined as 0.025 μg of cholecalciferol. At this potency, 1 gram of the oil provides sufficient Vitamin D3 for approximately 2,500–5,000 standard adult supplement servings, depending on the per-serving dosage in the finished product.

Q3: Can this oil be used directly in food production, or does it require further dilution?

A: It can be used directly where precise micro-dosing equipment is available, but it is more commonly further diluted by premix manufacturers to lower concentrations (e.g., 100,000 IU/g) for easier handling in large-scale food fortification. The 1,000,000 IU/g concentration is the standard feedstock from which these lower-potency dilutions are prepared.
