B Protin's Core Ingredients: A Multi-Source Protein Blend

At the heart of the B Protin formula is its unique blend of three high-quality proteins: whey, soy, and casein. This proprietary 'time-release' combination is designed to provide a sustained and continuous supply of amino acids to the body over an extended period.

The Purpose of the Triple Protein Blend

Whey Protein Concentrate: Known for its rapid absorption, whey provides a quick influx of amino acids after consumption. This makes it effective for immediate muscle repair and recovery, especially post-workout.
Soy Protein Isolate: This plant-based protein has an intermediate rate of digestion and is a complete protein, meaning it contains all nine essential amino acids. It helps bridge the gap between fast-absorbing and slow-absorbing proteins.
Casein Protein: Sourced from milk, casein is a slow-digesting protein. It forms a gel in the stomach, leading to a gradual release of amino acids. This provides a steady, long-lasting supply of nutrients, ideal for prolonged nourishment and muscle maintenance.

Carbohydrate and Energy Sources

To provide energy and support an active lifestyle, B Protin includes several carbohydrate sources.

Sucrose: A simple sugar that provides readily available energy.
Maltodextrin: A easily digestible complex carbohydrate that offers a quick source of energy without being excessively sweet.
Malt Extract: A natural source of carbohydrates and a flavor enhancer.

Fats and Dietary Fiber

B Protin is formulated to provide a balanced nutritional profile, which includes a source of dietary fats and fibre.

Oleic Sunflower Oil Powder: This ingredient provides essential fatty acids, contributing to the product's overall nutrient balance.
Inulin (Dietary Fibre): As a prebiotic fibre, inulin supports digestive health by promoting the growth of beneficial gut bacteria.

The Fortified Vitamin and Mineral Profile

To enhance its comprehensive nutritional value, B Protin is fortified with a wide array of essential vitamins and minerals. The exact composition can vary slightly depending on the variant and formulation, but often includes:

Vitamins: A, C, D, E, K, and B-complex vitamins like B1, B2, B6, B12, Niacin, and Folic Acid. These are crucial for functions ranging from immune support to energy metabolism.
Minerals: Calcium, Iron, Zinc, Magnesium, Potassium, Phosphorus, Manganese, Copper, Iodine, and Selenium. These minerals play vital roles in bone health, muscle function, oxygen transport, and immune defense.

Flavoring and Other Additives

While the base formula is consistent, flavoring ingredients are added to create different variants.

Chocolate Flavour: Includes natural cocoa powder.
Dry Fruit Flavour: Contains real dry fruits like almonds, dates, and raisins, adding natural antioxidants and vitamins.
Mango Flavour: Uses nature-identical mango flavoring along with coloring agents.
