Product Name & Strength: Nature's Field Vitamin D3 + Vitamin K2, 100 Capsules.
Indications (Approved Uses): Dietary supplementation for the prevention and management of vitamin D and vitamin K deficiencies. It is universally indicated for the maintenance of optimal bone density, skeletal strength, and dental health by facilitating the proper absorption and utilisation of dietary calcium. The synergistic combination is utilised to support cardiovascular health by promoting normal calcium metabolism in the vascular system, thereby helping to prevent arterial calcification. Furthermore, it provides essential nutritional support for immune system function and healthy muscle contraction.
Contraindications (Safety Warnings): Hypersensitivity to vitamin D3 (cholecalciferol), vitamin K2 (menaquinone), or any of the excipients in the formulation. It is strictly contraindicated in individuals with documented hypercalcaemia, hypercalciuria, hypervitaminosis D, or severe renal impairment. Use with extreme caution in patients with sarcoidosis or other granulomatous diseases due to an increased sensitivity to vitamin D. Crucial Interaction: Due to the presence of vitamin K2, this supplement must be used with strict medical supervision in patients taking anticoagulant medications (such as warfarin or other coumarin derivatives), as vitamin K directly antagonises their pharmacological effects and alters coagulation profiles.
Side Effects (Adverse Reactions): Generally well-tolerated when taken at the recommended daily dosage. Adverse reactions are primarily associated with excessive intake leading to hypercalcaemia or hypervitaminosis D. Symptoms of toxicity may include nausea, vomiting, constipation, anorexia, unexplained fatigue, excessive thirst (polydipsia), frequent urination (polyuria), and in severe cases, the formation of renal calculi (kidney stones) and cardiovascular calcification.
Active / Nutritional Information: Each veggie capsule provides a high-potency synergistic combination consisting of 125 mcg (equivalent to 5,000 IU) of Vitamin D3 as cholecalciferol and 100 mcg of Vitamin K2 as menaquinone, combined with standard non-active excipients including rice flour, hypromellose for the capsule shell, magnesium stearate, and dicalcium phosphate.
Instructions for Use / Dosage: For oral administration. Adults are typically advised to take one veggie capsule daily, preferably with a fat-containing meal to optimise the gastrointestinal absorption of these fat-soluble vitamins. Always consult the physical package labelling for exact manufacturer dosage guidelines or follow the direct advice of a healthcare professional.
