Thorne Research, Riboflavin 5' Phosphate, 60 Veggie Caps15 Reviews
The length of time for the expiration date or "best used before" date depends on the type of product, as well as the brand.
Perishable items (such as flax oils or certain probiotics) generally have shorter expiration dates. Although our warehouse is fully air-conditioned, these more fragile items are put in cold storage (freezer or refrigeration unit) for maximum freshness.
Our receiving department does its best to verify and then enter the correct expiration dates for all incoming products. However, discrepancies do occur from time to time. This being said, the exceptionally high turnover at iHerb ensures that our inventory is among the freshest in the industry.
The Shipping Weight includes the product, protective packaging material and the actual shipping box. In addition, the Shipping Weight may be adjusted for the Dimensional Weight (e.g. length, width & height) of a package. It is important to note that certain types of products (e.g. glass containers, liquids, fragile, refrigerated or ice packed) will often require protective packaging material. As such, these products will reflect a higher Shipping Weight compared to the unprotected product.

Riboflavin, also known as vitamin B2, plays a key role in the activation and conversion of other B vitamins. For instance, it is necessary for activation of vitamin B6, conversion of tryptophan to niacin, and conversion of folate to its various active forms. Riboflavin also plays a crucial role in fat and glucose metabolism, red blood cell synthesis, and the production and regulation of certain hormones.
As with many B vitamins, riboflavin must be converted to its active form – riboflavin 5'-phospate (R5P) – in order for it to be utilized by the body. Because absorption of riboflavin occurs in the upper GI tract, a compromised digestive system can adversely affect the body's ability to convert riboflavin to R5P. In addition, certain prescription medications can interfere with the proper absorption of riboflavin and deplete the body of its stores.

iHerb Customer Reviews
I love the Thorne brand and thought I'd try these. I've been cycling different B vitamins to see if any had an effect on my sleep, mood and memory. The one that actually helps is Vitamin B1 (Thiamine) which my research shows is easily blocked if you consume tea or red wine with meals (both contain tannins which block B1 absorption).
i believe that coenymated vitamins are more active than the usual ones, but i think this product would have to be used sublingually (dissolved under tongue), ive read the body will digest the coenzymation from it otherwise, and in my experience i think that is true, since this product had a diuretic effect on me, and ive read that is what happen when the b's arent used and are immediately flushed. ive opted for another coenzymated b complex that is sublingual and ive noticed things no other b complex has been able to do, such as increased body heat (imroved basal metabolic rate) and energy.
