Cholecalciferol
Very Good

Cholecalciferol, or Vitamin D3, is essential for calcium absorption and bone health. It is the preferred form of Vitamin D due to its superior bioavailability compared to Vitamin D2. It also supports immune function and has been linked to mood regulation.

Risks

Excessive intake can lead to hypercalcemia and associated health issues.

Benefits

Enhances calcium absorption and supports bone health.

Ascorbic Acid
Good

Ascorbic acid, also known as Vitamin C, is a powerful antioxidant that supports immune function and skin health. It is essential for the synthesis of collagen and the absorption of iron from plant-based foods. As a water-soluble vitamin, it is generally safe with a low risk of toxicity.

Risks

High doses may cause gastrointestinal disturbances such as diarrhea.

Benefits

Boosts immune function and enhances iron absorption.
