D3 (Cholecalciferol) 1000 IU by Bio-Tech – Bone Health Vitamin D3 Capsules
D3 (Cholecalciferol) 1000 IU capsules by Bio-Tech provide 25 mcg of vitamin D3 per capsule in a dry preparation. This single-nutrient formula supplies cholecalciferol rather than combining vitamin D with calcium or other active ingredients, making its contribution to your daily routine straightforward to identify.
Available in 100- and 250-capsule bottles, this single-nutrient supplement suits people who want to evaluate vitamin D separately from a multivitamin. The capsule contains gelatin, so it is not a vegetarian capsule. Its role is nutritional support: helping supply a vitamin involved in mineral use and normal cellular communication, rather than replacing calcium-rich foods or other daily nutrients.
Key D3 (Cholecalciferol) 1000 IU Benefits
- Supports calcium absorption, helping the body use calcium obtained from meals as part of a balanced nutritional routine.
- Contributes to bone health by supporting normal mineralization and the ongoing maintenance of the skeleton.
- Supports normal muscle function and nerve communication, while contributing to the vitamin D needs of cells involved in normal immune function.
How D3 (Cholecalciferol) 1000 IU Works
After absorption, cholecalciferol is converted in the liver and then primarily in the kidneys into forms the body can use. The active form acts as a messenger, interacting with receptors in the intestine and other tissues. In the intestine, that signaling helps regulate the movement of calcium from food into the bloodstream.
Vitamin D also participates in maintaining the calcium and phosphate balance needed for normal bone mineralization. These functions explain why vitamin D and calcium are complementary nutrients, not interchangeable ones. This formula supplies vitamin D without adding calcium; the calcium used by the body must still come from food or another appropriate source. More vitamin D is not automatically better, so account for overlapping supplements.
Key Functional Ingredients Include:
- Vitamin D3: Supports intestinal calcium absorption through the body's vitamin D signaling system. By helping the intestine transfer dietary calcium into circulation, vitamin D contributes to the mineral supply needed to maintain normal bone structure. Its nutritional role complements adequate calcium intake rather than supplying calcium itself.

- People who prefer a dry capsule rather than a liquid or an oil-filled softgel.
- Those comparing 100- and 250-capsule sizes of the same 1,000 IU formula, with healthcare guidance on whether this strength fits their total intake.

Vitamin D₃ (as cholecalciferol) ... 25 mcg (1,000 IU) — 125% Daily Value
Other Ingredients: microcrystalline cellulose, gelatin capsule
Does Not Contain: Dairy, egg, fish, shellfish, nuts, wheat, gluten, soy, sugar, yeast or artificial colors.
Storage: Store tightly closed in a cool, dry place.
Additional precautions: Always check with your healthcare practitioner before starting a new supplement, especially during pregnancy or breastfeeding, with kidney problems or high blood calcium, or when taking medications. Orlistat can reduce vitamin D absorption; steroids such as prednisone can lower vitamin D levels. Thiazide diuretics combined with vitamin D can raise blood calcium too high. High-dose vitamin D can also affect some statins. Excessive supplemental vitamin D can cause nausea, vomiting, muscle weakness, confusion, pain, appetite loss, dehydration, excessive urination, thirst, and kidney stones; severe excess can damage kidneys or cause an irregular heartbeat. Review all vitamin D sources with your practitioner rather than increasing this dose yourself.
Frequently Asked Questions About D3 (Cholecalciferol) 1000 IU
What are the benefits of D3 (Cholecalciferol) 1000 IU?
This Bio-Tech formula supplies 25 mcg (1,000 IU) of vitamin D3 in each capsule. Vitamin D helps the intestine absorb calcium and supports the mineral balance needed for healthy bones. It also contributes to normal muscle, nerve, and immune function. The formula is focused on vitamin D rather than a combination of bone nutrients, so it does not provide calcium. Adequate calcium intake and an appropriate overall diet remain important alongside the capsule.
Who should take D3 (Cholecalciferol) 1000 IU?
Adults looking for a separate vitamin D3 supplement can discuss this 1,000 IU strength with their healthcare professional. It may fit a routine where vitamin D intake is being considered separately from a multivitamin or calcium supplement. Both bottle sizes contain the same capsule formula, including a gelatin capsule that is not suitable for a vegetarian preference. People who are pregnant, breastfeeding, taking medication, or managing kidney or calcium-related concerns should obtain individualized guidance before using it.
Are there any side effects of taking D3 (Cholecalciferol) 1000 IU?
The label states: Keep out of the reach of children. Safety sealed for your protection. Additional precautions: Excessive vitamin D can cause nausea, vomiting, weakness, confusion, appetite loss, dehydration, increased thirst or urination, and kidney problems. Review total intake from this 1,000 IU capsule and other supplements. Thiazide diuretics can increase the risk of high blood calcium; orlistat reduces absorption, and steroids can lower vitamin D levels. High-dose vitamin D can affect some statins. Ask your practitioner about medication combinations, kidney problems, pregnancy, or breastfeeding before starting.
How does D3 (Cholecalciferol) 1000 IU support overall health?
Vitamin D3 connects everyday nutrient intake with the body's calcium-handling system. After the body converts cholecalciferol to its active form, vitamin D signaling helps regulate intestinal calcium absorption and supports normal bone mineralization. Vitamin D also has roles in normal muscle and immune cell function. This capsule adds vitamin D without supplying the calcium or other nutrients your diet provides. Its usefulness depends on how the 1,000 IU serving fits your existing intake and individual nutritional needs.
