| **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 | African star apple (Chrysophyllum albidum) contains bioactive phenolic compounds—including beta-amyrin acetate, epicatechin, and epigallocatechin—that inhibit α-glucosidase and α-amylase enzymes in a dose-dependent manner, with its pulp coat demonstrating potent α-amylase inhibition (IC₅₀ of approxi |
| **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 | African star apple exerts its biological effects primarily through dual enzymatic inhibition: its phenolic compounds—beta-amyrin acetate, epicatechin, and epigallocatechin—competitively bind the active sites of α-glucosidase and α-amylase, slowing the hydrolysis of complex carbohydrates into absorba |
| **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: Fresh fruit, juice, roasted seeds, extracts.
- Traditional Use: Eaten fresh, juiced, or incorporated into desserts; roasted seeds consumed as snacks.
- Modern Applications: Used in smoothies, functional beverages, dietary supplements, and skincare products.
- Recommended Dosage: 1/4– |
| **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 | African star apple is widely consumed as a traditional fruit across West and Central Africa and is generally regarded as safe when eaten as part of a normal diet. Due to its demonstrated α-amylase and α-glucosidase inhibitory activity, individuals taking antidiabetic medications such as metformin or |
