Key Benefits of Vitamin D
-
Bone Health: Vitamin D contributes to the maintenance of normal bones and teeth by regulating calcium and phosphorus absorption.*
-
Immune Function: Adequate vitamin D levels contribute to the normal function of the immune system, helping your body defend against seasonal challenges.*
-
Muscle Function: Vitamin D supports normal muscle function, which is important for mobility in older adults.*
-
Calcium Absorption: Without enough vitamin D, the body cannot absorb calcium efficiently, even if you consume enough through diet.*
Understanding Vitamin D3 and D2
Vitamin D comes in two forms: D2 (ergocalciferol) and D3 (cholecalciferol). D3 is naturally produced by the skin when exposed to sunlight and is considered more bio-available and effective at raising blood levels of vitamin D. NOW Foods uses D3 sourced from lanolin, ensuring a high-quality, consistent dose. Research suggests that D3 may be more potent than D2, making it the preferred choice for supplementation.
Who Should Consider Vitamin D Supplementation?
Certain populations are at higher risk for low vitamin D levels. These include individuals with limited sun exposure (indoor lifestyles, northern latitudes), people with darker skin (higher melanin reduces vitamin D synthesis), older adults (skin synthesis declines with age), and those following vegan diets (if D3 from lanolin is not desired, a vegan D3 from lichen alternative may be considered). If you fall into any of these categories, a 5,000 IU (125 mcg) supplement like NOW Foods Vitamin D3 can help maintain optimal levels.*
Recommended Dosage and Usage
Each soft gel capsule contains 5,000 IU (125 mcg) of vitamin D3. For most adults, taking one soft gel capsule daily with a meal containing fat enhances absorption. Many health care professionals suggest starting with a higher dose if deficiency is suspected, then adjusting based on blood tests. Do not exceed the recommended dose. Always consult your doctor before beginning any new supplement regimen.

Why Choose NOW Foods Vitamin D3 5,000 IU?
Vitamin D is essential for overall health, yet many people fall short due to limited sun exposure or dietary intake. NOW Foods Vitamin D3 5,000 IU delivers a high-strength dose of cholecalciferol—the preferred form of vitamin D—in a practicable liquid soft gel capsule for optimal absorption. The liquid soft gel capsule form offers enhanced absorption compared to dry tablets, as vitamin D is fat-soluble and the soft gel capsule includes a small amount of oil to aid uptake. With 5,000 IU per serving, this high-strength formula is ideal for those with increased needs or confirmed deficiency. The third-party GMP certification means every step of manufacturing—from raw material sourcing to final packaging—meets rigorous standards.
Frequently Asked Questions About Vitamin D3
What is the difference between vitamin D2 and D3?
Vitamin D3 (cholecalciferol) is the form produced by your skin and found in animal sources. It is more effective at raising and maintaining blood levels of vitamin D than D2 (ergocalciferol), which comes from plants and fortified foods. NOW Foods uses D3 for superior bioavailability.
Can I take this supplement on an empty stomach?
Because vitamin D is fat-soluble, it is best absorbed when taken with a meal containing fat. Taking it with a source of healthy fat like avocado, nuts, or olive oil can significantly improve absorption.
How long does one bottle last?
Each bottle contains 30 softgels, providing a 30-day supply when taken as directed (one soft gel capsule daily).
Potential Side Effects and Safety
Vitamin D is generally well tolerated, but excessive intake (typically above 10,000 IU daily for extended periods) can lead to toxicity. Symptoms include nausea, weakness, and kidney issues. Stick to the recommended dosage and consult your health care provider if you have any concerns or are taking medications that may interact with vitamin D.
