High-strength vitamin D3 formula
Suitable for targeted vitamin D supplementation
Vitamin D3 is converted in the body into active vitamin D metabolites. These compounds help regulate calcium and phosphorus metabolism and contribute to the maintenance of healthy bones and teeth.
Vitamin D also plays a role in normal muscle and immune-system function.
The 125 mcg (5,000 IU) strength is considerably higher than the general daily recommended intake for many adults, so regular use at this dose is best guided by individual nutritional needs and, when appropriate, vitamin D blood testing.
Vitamin D3 is absorbed through the digestive tract and metabolized into active forms that help regulate calcium and phosphorus balance.
Adequate vitamin D supports the absorption of calcium and contributes to normal bone mineralization. Vitamin D receptors are also present throughout the body, including immune and muscle tissues.
Because this product contains a high dose, more is not necessarily better. Appropriate intake depends on diet, sunlight exposure, existing vitamin D levels, age, and individual health factors.
Take the recommended serving according to the current product label.
Because 5,000 IU (125 mcg) is a high-strength dose, do not routinely use it above the recommended amount without guidance from a qualified healthcare professional.
If you are already taking a multivitamin, calcium formula, cod liver oil, or another vitamin D supplement, consider your total vitamin D intake from all sources.
