This supplement is a special form of vitamin B2, riboflavin. It is beneficial for metabolism, the nervous system, and maintaining energy levels. Therefore, maximum absorption is very important to me. One capsule contains the optimal daily dose. And that's very convenient.

최고!

The Nutricost R-5-P (50mg, 120 capsules) is an excellent source of pre-activated Vitamin B2 (Riboflavin-5-Phosphate). I chose this product for its high bioavailability, as the R-5-P form is easier for the body to utilize directly for energy and nervous system support. I've noticed a subtle but consistent increase in my sustained energy levels. The capsules are small and easy to swallow. The large 120-count bottle offers great value. Nutricost maintains high purity with no unnecessary fillers. This is a great choice for optimizing B-vitamin intake, especially if you seek the more effective R-5-P form. Reliable and recommended for enhanced B2 metabolism!

Great

Good quality with simple ingredients. I was glad to find vitamin B2 in the riboflavin-5-phosphate form. The dosage is reasonable and the price is decent for 120 capsules.

Noticeable results with the MTRR gene mutation: clear mind, energy, and deep focus!

I started taking R-5-P (the active coenzyme form of Vitamin B2) based on my DNA test results, which revealed a mutation in the MTRR gene. I’ve been taking it as part of a comprehensive protocol to support my folate cycle for over 3 months now. The results are truly tangible: Energy & Productivity: My energy levels have stabilized throughout the day. My stamina has noticeably increased—I can now stay productive and fully focused on tasks for 5 to 6 hours straight. Brain Fog Lifted: The "brain fog" is completely gone, making it much easier to think clearly. Appetite Control: As a pleasant bonus, my cravings for simple carbs and quick calories have decreased significantly. An excellent, highly effective form of Vitamin B2. If you have similar health goals or genetic traits, I highly recommend it! Quality is perfect.

Very Bioavailabile form of B2

This supplement is great for overall health, and because it’s water soluble there’s no nasty bad effects as excess r5p b2 will just get urinated out

Great value for money!

This riboflavin (Vitamin B2) supplement provides a high-potency dose of 50 mg per capsule, which is ideal for those needing targeted support. It plays an essential role in energy production and helps reduce fatigue throughout the day. Vitamin B2 is also important for maintaining healthy skin, vision, and nervous system function. I appreciate that the formula is simple and contains minimal additional ingredients. The capsule is easy to take and suitable for daily use. A higher dose like this can be especially helpful for people with increased nutritional needs. Overall, it’s a straightforward and effective B2 supplement that delivers reliable support.
