FAQ
Q1. What is the difference between Riboflavin and Riboflavin-5-Phosphate?
Ans: Riboflavin is standard Vitamin B2, which requires conversion by liver enzymes before your cells can use it. Riboflavin-5-Phosphate (R-5-P) is the bioactive, coenzymated form that bypasses this step, ensuring faster and more efficient absorption directly by your cells.
Q2. Who should take an active-form Vitamin B2 supplement?
Ans: This supplement is ideal for adults seeking optimized daily energy metabolism, nervous system support, or vision health. It is particularly beneficial for individuals whose bodies may struggle with converting regular dietary B vitamins into their active states.
Q3. Can this product be taken on an empty stomach?
Ans: While it can be taken with or without food, taking this water-soluble vitamin capsule with a meal and a glass of water may help enhance comfort and support optimal absorption.
Q4. Is this Swanson R-5-P supplement authentic and imported to India?
Ans: Yes, this product is a 100% authentic USA import. Rudra Retails sources wellness supplements directly from trusted distributors in the United States, ensuring genuine quality and secure delivery to your doorstep.
Q5. Does this product contain any common allergens?
Ans: This natural wellness formula is delivered in unflavored vegetarian capsules and is gluten-free. It uses simple, clean ingredients like brown rice flour and vegetable cellulose, making it highly compatible with various dietary preferences.
