| **Overview** | 25-hydroxyvitamin D (25(OH)D) is the primary circulating form of vitamin D and the most accurate biomarker for vitamin D status in the body. It functions as a prohormone that gets converted to the active hormone calcitriol (1,25(OH)2D3) in the kidneys to regulate calcium homeostasis and immune funct | Achiote (Bixa orellana) seeds contain the carotenoid bixin and δ-tocotrienol, which scavenge reactive oxygen species and inhibit lipid peroxidation through hydrogen donation mechanisms. These compounds demonstrate antioxidant activity with ABTS SC₅₀ of 61.49 µg/mL and protective effects against oxid |
| **Mechanism of Action** | 25-hydroxyvitamin D is converted to the active hormone calcitriol (1,25(OH)2D3) by the enzyme 1α-hydroxylase in the kidneys. Calcitriol binds to vitamin D receptors (VDR) in target tissues, forming complexes with retinoid X receptors that regulate gene transcription. This pathway controls calcium ab | Bixin, derived from lycopene through carotenoid cleavage dioxygenase enzymes, and δ-tocotrienol work synergistically to scavenge reactive oxygen and nitrogen species including H₂O₂, HOCl, O₂⁻, NO, and ONOO⁻. These compounds donate hydrogen atoms to neutralize free radicals, reduce lipid peroxidation |
| **Dosage** | 25-Hydroxyvitamin D is typically measured in blood tests rather than supplemented directly. Consult a healthcare provider for vitamin D supplementation advice. | - Common forms include whole seeds, ground powder, and infused oils.
- Traditionally ground into a paste or powder for culinary use as a natural food coloring or marinade.
- Modern culinary applications include flavoring rice, cheeses, and various Latin American and Caribbean dishes.

| **Safety** | 25-hydroxyvitamin D testing is generally safe as a blood biomarker with no direct side effects from measurement. However, vitamin D supplementation to raise 25(OH)D levels can cause hypercalcemia and kidney stones at doses exceeding 4,000 IU daily long-term. Thiazide diuretics and digoxin may increa | No major safety concerns, drug interactions, or contraindications are documented in available research. Animal studies indicate protective effects occur at non-toxic doses with demonstrated antigenotoxic properties. However, comprehensive human safety data is absent, including effects during pregnan |
