Vitamin D3 + Vitamin K1 + Vitamin K2: Brands, Price & Uses in Bangladesh

Vitamin D3 + Vitamin K1 + Vitamin K2 is a combination fat-soluble vitamin supplement containing cholecalciferol (vitamin D3), phylloquinone (vitamin K1), and menaquinone (vitamin K2). It is used for the following purposes, classified by strength of evidence:

Established/guideline-supported uses

• Prevention and treatment of combined vitamin D and vitamin K insufficiency/deficiency in individuals with inadequate dietary intake or limited sun exposure.
• Supportive therapy for bone health, as an adjunct to adequate calcium intake, in individuals at risk of low bone mineral density (e.g., postmenopausal women, older adults), used alongside — not as a replacement for — physician-directed osteoporosis therapy where indicated.

Adjunct / evidence-evolving uses

• Supporting the body's calcium-regulation pathway, based on the physiological premise that vitamin D increases intestinal calcium absorption while vitamin K (via carboxylation of osteocalcin and matrix Gla-protein) helps direct that calcium toward bone rather than soft tissue and blood vessel walls. Clinical evidence for a measurable added cardiovascular or fracture-reduction benefit of combining vitamin D3 with vitamin K1/K2, compared with vitamin D alone, is still evolving and not yet conclusively established in large outcome trials.
• General dietary supplementation to help meet recommended daily allowances of vitamins D and K in people with restricted diets, malabsorption risk factors, or increased requirements.

This product is a dietary/nutritional supplement rather than a treatment for a specific diagnosed disease, and it does not replace prescribed medical therapy for osteoporosis, cardiovascular disease, or diagnosed vitamin deficiency requiring high-dose prescription repletion.

Dosing of Vitamin D3 + Vitamin K1 + Vitamin K2 depends on the specific product strength and the indication. The following is general guidance; always follow the product label or a physician's/pharmacist's specific instructions.

Administration: Take orally, preferably with a meal containing some fat, as vitamin D and vitamin K are fat-soluble and absorption is improved when taken with food. Swallow tablets/capsules whole with water unless the product is designed to be chewed or taken as drops. Do not exceed the labeled daily dose. Do not combine with other vitamin D or vitamin K–containing supplements without medical advice, to avoid exceeding recommended total daily intake.

Vitamin D3 + Vitamin K1 + Vitamin K2 is generally well tolerated at recommended supplement doses. Reported side effects are usually mild and include:

• Gastrointestinal upset: mild nausea, constipation, or stomach discomfort.
• Headache.
• Mild allergic-type skin reactions (rash, itching) in sensitive individuals.

Symptoms of excessive intake/toxicity (typically only with doses well above the recommended daily amount, sustained over time) can include those of hypercalcemia — nausea, vomiting, weakness, frequent urination, confusion, and in severe cases kidney problems or abnormal heart rhythm; these are uncommon at labeled supplement doses. Seek medical advice if such symptoms occur.
