Vitamin D3 (cholecalciferol) 2,500 IU (62.5 mcg) per softgel in MCT oil from non GMO coconut oil. Supports bone and teeth health, calcium absorption, and immune function. MCT oil provides efficient fat-soluble vitamin absorption without requiring a separate fat containing meal.

Why 2,500 IU?

2,500 IU (62.5 mcg) is a mid potency dose positioned between the standard 1,000 IU daily reference intake and the high-potency 5,000 IU dose. It is suited for adults who want more than the standard dose particularly those with limited sun exposure or living at northern latitudes where UVB exposure is restricted during winter months without the higher potency that warrants closer healthcare supervision. Consult a healthcare practitioner to determine if this dose is appropriate for your individual needs.

Why MCT Oil?

Vitamin D3 is a fat soluble vitamin that requires fat for absorption. MCT oil (C8 and C10 medium chain triglycerides from non GMO coconut oil) is absorbed directly into the portal vein without requiring bile emulsification providing efficient fat soluble vitamin absorption that does not depend on a fat containing meal.

Who This Is For

Adults 18 and older seeking a mid potency Vitamin D3 supplement particularly those with limited sun exposure, living at northern latitudes, or wanting bone, calcium, and immune support beyond the standard 1,000 IU dose. To be taken with an adequate intake of calcium. Not suitable for vegans or vegetarians. Consult a healthcare practitioner before use if you have kidney disorders or take prescription medications.

Clinical Research

Vitamin D3 is more potent than vitamin D2 in humans

Journal of Clinical Endocrinology & Metabolism, 2011

This randomized, double blind trial directly compared the efficacy of Vitamin D3 (cholecalciferol) versus Vitamin D2 (ergocalciferol) at equal doses in raising serum 25-hydroxyvitamin D (25(OH)D) levels in healthy adults over 12 weeks. Participants received either 1,000 IU of D3 or 1,000 IU of D2 daily. At 12 weeks, the D3 group showed significantly higher serum 25(OH)D levels compared to the D2 group, with D3 demonstrating approximately 87% greater potency than D2 in raising and maintaining 25(OH)D blood levels. The authors concluded that Vitamin D3 is significantly more effective than D2 at raising serum 25(OH)D the storage and clinically measured form of Vitamin D and recommended D3 as the preferred supplemental form. This finding directly supports the use of cholecalciferol (D3) as the active ingredient in this formula, and the clinical relevance of 25(OH)D blood level monitoring when supplementing at 2,500 IU per day.

Vitamin D supplementation and risk of acute respiratory tract infections: a systematic review and meta analysis

BMJ, 2017

This landmark systematic review and meta analysis of 25 randomized controlled trials (total 11,321 participants) examined the protective effect of Vitamin D supplementation against acute respiratory tract infections. Vitamin D supplementation was associated with a statistically significant reduction in the risk of acute respiratory infection across all participants (adjusted OR 0.88, 95% CI 0.81–0.96). The protective effect was strongest in participants who were Vitamin D deficient at baseline (25(OH)D < 25 nmol/L) and in those receiving daily or weekly supplementation rather than bolus doses. The proposed immune mechanisms include Vitamin D's role in inducing antimicrobial peptides (cathelicidin and defensins) in innate immune cells, modulating T-cell differentiation and cytokine production in adaptive immunity, and maintaining epithelial barrier integrity. These immune mechanisms are directly relevant to the immune function support positioning of this 2,500 IU D3 formula, particularly for adults with limited sun exposure during winter months

Vitamin D and calcium supplementation reduces cancer risk: results of a randomized trial

American Journal of Clinical Nutrition, 2007 (Lappe et al.); supported by review in Osteoporosis International, 2005

Multiple systematic reviews and clinical trials have established the role of Vitamin D3 in bone health through its effects on intestinal calcium absorption and bone mineralization. Vitamin D3 (cholecalciferol) is converted to calcitriol (1,25-dihydroxyvitamin D), which binds to the Vitamin D receptor (VDR) in intestinal enterocytes and upregulates expression of calcium transport proteins particularly TRPV6 and calbindin-D9k increasing transcellular calcium absorption. Without adequate Vitamin D, calcium absorption from the diet decreases significantly, and the body compensates by resorbing calcium from bone via parathyroid hormone (PTH) driven osteoclast activity, reducing bone mineral density over time. Adequate Vitamin D3 status is therefore a prerequisite for effective calcium utilization and bone mineralization.

Frequently Asked Questions

What is Vitamin D3 2500 IU used for?

Vitamin D3 helps support healthy bones and teeth, calcium absorption, immune function, and overall wellness.

What are the benefits of Vitamin D3?

Vitamin D3 helps the body absorb and use calcium and phosphorus, which are important for maintaining strong bones and teeth. It also supports normal immune system function.

Why is MCT oil included in Vitamin D3?

Vitamin D3 is a fat soluble vitamin, and MCT oil provides an oil based carrier that helps deliver vitamin D3 in an easily absorbed format.

Is Vitamin D3 with MCT oil better absorbed?

Taking vitamin D3 with dietary fat can support its absorption. An MCT oil based formula provides vitamin D3 together with a fat source in the same serving.

How does Vitamin D3 support bone health?

Vitamin D3 helps increase the absorption and utilization of calcium and phosphorus, minerals that are essential for maintaining healthy bones and teeth.

Does Vitamin D3 support the immune system?

Yes. Vitamin D contributes to the normal function of the immune system and plays an important role in several cellular processes.

When is the best time to take Vitamin D3 2500 IU?

Vitamin D3 can generally be taken at any convenient time, but taking it with a meal containing fat may support absorption.
