What is Thorne Riboflavin 5'-Phosphate?
It's a vitamin B2 supplement that provides riboflavin in its already activated form, riboflavin 5'-phosphate, rather than standard riboflavin.
Why does the activated form matter?
Riboflavin needs to be converted to riboflavin 5'-phosphate before the body can use it. Digestive issues or certain medications can interfere with that conversion, which can lead to a functional B2 shortfall even if someone is getting riboflavin from food or a standard supplement. Taking the pre-activated form skips that conversion step.
What does riboflavin do in the body?
It's a key cofactor for activating and converting other B vitamins, including turning on vitamin B6 and converting tryptophan into niacin and folate into its active forms. It also plays a role in fat and glucose metabolism, red blood cell production, healthy methylation, mitochondrial energy production, and hormone regulation.
What's the suggested dose?
Most sources list 1 capsule one to three times daily, or as recommended by a healthcare practitioner. A couple of retailers list a simpler 1 capsule daily, so check your current bottle to confirm.
Who might use this product?
People wanting broader B2 or methylation support, especially those whose digestion or medication use might limit how well they convert standard riboflavin into its active form.
Are there any precautions?
This product shouldn't be used by anyone with a known hypersensitivity to its ingredients. If pregnant, nursing, or taking medications, consult a healthcare practitioner before use. No known adverse interactions have been reported as of the product's most recent labeling.
Is it third-party tested or certified?
Yes, it's listed as third party certified.
Is it free of common allergens?
Yes, it's free of gluten, dairy, and soy.
How should it be stored?
Store tightly sealed in a cool, dry place, and use only if the tamper evident seal is intact.
