How it works
Thorne’s Active B2 is a premium vitamin B2 supplement designed to deliver the bioavailable form of riboflavin that is more easily absorbed and utilized by the body. Riboflavin, also known as vitamin B2, plays a crucial role in energy production, cellular function, and the maintenance of healthy skin, eyes, and nervous system. Thorne’s Active B2 ensures that your body receives this vital nutrient in its most effective form, helping to support overall health and well-being.
In addition to its direct benefits, Active B2 is essential for the formation of other B vitamins, including niacin (B3) and active B6. This interconnectedness makes vitamin B2 an important nutrient for those looking to maintain a balanced and healthy metabolism. It also aids in the body’s methylation processes, a vital function that supports DNA synthesis, detoxification, and a wide array of cellular activities. By ensuring your body has an adequate supply of riboflavin, Active B2 helps maintain these critical biochemical processes.
Thorne’s commitment to purity means that Active B2 is free from gluten, soy, dairy, eggs, tree nuts, peanuts, shellfish, and fish. This makes it an ideal choice for individuals with food sensitivities or allergies. Every Thorne product is crafted with the highest quality ingredients, rigorously tested to ensure safety and effectiveness. With this product, you can be confident that you are supporting your body with the cleanest, most reliable supplements available.

Everything you need to know about this product.
What is Thorne Riboflavin 5 Phosphate?
Thorne Riboflavin 5 Phosphate, also called Active B2, is a vitamin B2 supplement that delivers 36.5 mg of riboflavin 5'-phosphate sodium per capsule. This is the bioavailable form of B2, meaning your body can absorb and use it more readily than standard riboflavin. It comes in a bottle of 60 capsules.
What does riboflavin 5'-phosphate do, and why does it matter?
Riboflavin 5'-phosphate is the active form of vitamin B2 and plays a key role in energy production, cellular function, and nervous system health. It also supports healthy methylation processes, which are important for DNA synthesis, detoxification, and overall cellular activity. On top of that, B2 is essential for the formation of other B vitamins, including niacin (B3) and active B6, making it a foundational nutrient for balanced metabolism.
How do I take Thorne Riboflavin 5 Phosphate?
Take 1 capsule one to three times daily, or as recommended by your healthcare practitioner. Depending on how many capsules you take per day, the bottle provides roughly a 20- to 60-day supply.
Who is this product a good fit for?
It suits adults looking to support energy levels, methylation, metabolism, or nervous system health with a bioavailable form of B2. It is free from gluten, soy, dairy, eggs, tree nuts, peanuts, shellfish, and fish, so it may be a good choice if you have common food sensitivities. If you are pregnant, breastfeeding, taking medication, or considering this for a child, consult a qualified healthcare practitioner first.
How does this compare to other B vitamin products you carry?
Thorne Riboflavin 5 Phosphate is a standalone active B2, so it is ideal if you specifically want targeted riboflavin support. If you need broader B vitamin coverage, Thorne's Active B-Complex or B-Complex 100 mg Sustained Release each deliver a full range of B vitamins in one product. PureGenomics B-Complex is another multi-B option worth considering. There is also a standard Riboflavin supplement available if you want a simpler form of B2 without the phosphorylated version.
