Analysis

Thorne's Riboflavin 5'-Phosphate delivers Vitamin B2 in its pre-converted, activated form, making it immediately available for use by the body's metabolic processes. This is particularly advantageous for individuals with genetic polymorphisms (e.g., MTHFR) that can hinder the body's ability to convert standard Riboflavin into its active coenzyme form. Although the 36mg dose might seem lower than many standard Riboflavin supplements, the superior bioavailability means it can be more effective on a per-milligram basis. Thorne is widely recognized as a high-quality, professional-grade brand, which, combined with positive user reviews, reinforces the product's reliability despite its higher price point.

Pros
  • Contains Riboflavin in its activated (5'-Phosphate) form for superior bioavailability.
  • From Thorne, a highly reputable brand known for purity and quality.
  • Supports individuals with genetic variations affecting B vitamin conversion.
Cons
  • Very high price per serving compared to standard Riboflavin products.
  • Lower milligram dose than many standard supplements, requiring understanding of activated form benefits.

General Health 95.0
Providing riboflavin in its bioavailable, activated form ensures maximum utility for various bodily functions, including antioxidant support, red blood cell formation, and overall metabolic health. This product offers superior support for general well-being for a broader range of individuals.
Vision Support 90.0
As the active form, Riboflavin 5'-Phosphate can more readily contribute to maintaining eye health and protecting against oxidative stress. While 400mg of standard Riboflavin is common for specific vision-related issues, this activated form provides potent support for general eye health at a lower dose.
