Vitamin D3 1000IU, 100 Capsules by Klaire Labs is a dietary supplement designed to support healthy functioning of the body. Each bottle contains 100 capsules, each delivering a dosage of 1000 International Units (IU) of Vitamin D3, also scientifically known as Cholecalciferol. The product makes up for Vitamin D deficiency in the body, often caused by lack of exposure to sunlight or insufficient intake in diet.

Vitamin D3 is critical in the absorption of calcium and phosphorous, aiding in the formation and maintenance of healthy bones and teeth. It also contributes to the normal functioning of the immune system. The primary ingredient in the Klaire Labs' capsules is sourced from lanolin, derived from the wool of sheep.

The capsules are hypoallergenic and free from common allergens, thus suitable for individuals with dietary sensitivities. They do not contain milk/casein, eggs, fish, shellfish, tree nuts, peanuts, wheat, and gluten. Additionally, they are free from artificial colors, flavors, and preservatives.

The recommended dose is one capsule daily, or as directed by a healthcare professional. It should be taken preferably with a meal. Klaire Labs adheres to strict quality assurance guidelines in the manufacture of all its products and the Vitamin D3 1000IU capsules are no exception. It’s important to note that individuals should not exceed the recommended daily dose, and should consult a healthcare expert before starting any new dietary supplement.
