General and Chemical Information

Vitamin A is a fundamental nutrient that supports vision, cell differentiation, and the immune system in the body. In the dietary supplement sector, this vitamin is typically represented by synthetic ester forms, which offer high stability. These forms provide high efficiency in terms of Vitamin A activity (Retinol Equivalents). Chemically, these compounds belong to the retinoid class and are incorporated into the body's necessary metabolic processes.

Product Forms

The Vitamin A raw material in our product catalog is available as powdered ester salts with high activity values. The following specific forms stand out in our scientific and technical analyses:

  • Retinyl Palmitate (Powder 250,000 IU): One of the forms with standard activity values widely used in the food industry and supplement production.
  • Retinyl Palmitate (Powder 500,000 IU): Forms containing a higher concentration of active substance, requiring dosage precision.

Permissibility for Addition to Food

The legal basis for adding Vitamin A to foods and dietary supplements is determined within the framework of the Regulation on the Addition of Vitamins and Minerals to Foods (GeneratePdf.pdf) published by the General Directorate of Food and Control of the Ministry of Agriculture and Forestry of the Republic of Türkiye. Vitamin A is included in the EC-1 list of this regulation, permitting its use as a food supplement.

Daily Intake Dosage in Dietary Supplements

One of the most important aspects to consider when placing dietary supplements on the market is the specified daily intake dosages. In our current information database records, specifically the "Instructions for Approval Procedures for Dietary Supplements" and the current Restricted Substances List documents, no specific daily intake dosage limit or value is specified for Vitamin A. Therefore, strict compliance with dosage limits and labeling instructions, which are the responsibility of the manufacturer in product formulations, is required.

Regulations and Restrictions

The approval processes for dietary supplements are carried out in accordance with the Instructions for Approval Procedures for Dietary Supplements dated 3/7/2026 (takviye_g_databli_i_2026.pdf). Within the scope of these instructions, approval is mandatory for each dietary supplement placed on the market. Labeling and advertising of products containing Vitamin A must comply with the specified general provisions; a specification certificate appropriate for the daily intake dosage recommended for consumption according to age group must be issued. Regardless of whether the product is imported or domestically produced, the approval application must be made to the authorized Provincial Directorates of Agriculture and Forestry.
