Does the job

I take about 300mg a day for my migraines and it's definitely doing what it's supposed to. This product, and honestly any B2 or riboflavin product worth its salt, is also good for anyone who suffers from fishy smell as it upregulates the enzyme that takes care of all this stuff.

great for stress and exhaustion

this is a good b vitamin for stress, exhaustion, low thyroid, and depression. if you suffer from hypothyroidism or hyperthyroidism, be sure to not take b within 2 hours of your medication for thyroid. iodine is also ESSENTIAL, even though it's not always found in table salt now.

Good source of Vitamin B2

This is a good supplement, very well priced, and dosed in small enough doses to take multiple times a day in order to spread out absorption.

Energy boost

Quality is excellent — capsules are well-made, clearly labeled, and contain a standardized dose of riboflavin. Benefit after a few months includes improved energy levels, enhanced metabolism, and better overall vitality. Ingredients are straightforward: riboflavin with minimal fillers. Capsule size is moderate, easy to swallow. Taste is nonexistent since it is fully encapsulated, leaving no aftertaste.
