Vitamin D3 - 5000IU (2-Pack)
125 mcg (5000 IU) / 100 Softgels / 3 Months Supply
Jarrow Formulas® Vitamin D3 (cholecalciferol) may help improve vitamin D status better than equivalent amounts of ergocalciferol (D2).* D3 is also the form produced by skin with UVB exposure (sunlight). Vitamin D3 is converted to its hormonally-active form, calcitriol, which enhances dietary calcium and phosphorous absorption, supports the production of osteocalcin (a structural protein in bone), and stimulates the vitamin D receptor in innate immune cells to support a healthy immune response.*

Benefits that get better with time
Your body starts absorbing and utilizing active ingredients. A consistent daily intake allows nutrient levels to build toward effective concentrations.
With steady levels established, the formula starts working with your body's natural processes. This is where quality ingredients and clinically relevant doses begin to show.
Compounding benefits take hold. Sustained, balanced support builds over time, and many customers report this is when they start to feel a noticeable difference.
Why Jarrow Formulas
Science first, since 1977. For nearly five decades, Jarrow Formulas has formulated supplements around published science: the clinically studied ingredient forms, at the doses research actually used.
- Clinically studied ingredients. We use the specific branded forms found in published human research: GR-1 and RC-14 probiotic strains, Cognizin citicoline, StimuCal MCHA calcium, Kaneka ubiquinol, and more.*
- Bioavailable active forms. Your body shouldn't have to convert what it can absorb directly. That's why we use methylated B12 and folate instead of synthetic forms, and ubiquinol instead of standard Co-Q10 along with enhanced-absorption delivery systems.*
- Purity you can verify. Non-GMO ingredients, gluten-free and vegan options across the line, and quality controls like citrinin-avoidance fermentation and freeze-dried protein processing.
- Formulated to matter. Clinically relevant doses, strain-level identification on probiotics, and supplement facts that say exactly what is inside.
