BulkSupplements.com Riboflavin Powder - as Vitamin B2, Vitamin B2 Supplement - Riboflavin 400mg, B Vitamins for Wellness, Gluten Free, 400mg per Serving, 500g (1.1 lbs) (Pack of 1)

I try to get as many of my supplements from this company as I can. They are always good quality, competitively priced, and seem to be adding new products all the time. After ordering another product I was offered the opportunity to receive a product of my choice in exchange for my honest review. I greatly appreciate this as well as I get the opportunity to try something new with the risk of feeling it was money down the drain if it's no good, or just no good for me. Truthfully I never really fear this with this company, I've been using their products for years and will continue to do so. It's difficult to say whether this specific product is doing a whole lot as it was prescribed by my neurologist at a dosage of 400mg daily as part of a migraine reduction regimen. What I can say is most B vits nearly gag me they smell so bad just opening the bottle, and it takes a LOT to kick this in for me. I was a little worried about getting powdered B's fearing it would ruin my AM cocktail but this one is practically odorless and changed nothing about the taste of my drink so I'm pretty happy :)

Works for me and mild common headaches sometimes combine with coq10 sometimes not as that's more expensive and slightly stimulating. Very good bulk deal. I wish bag sealed more tightly though be very cautious about that as the stains are similar to turmeric stains, but not sure if they are easier to get out I wouldn't risk it. Not a strong taste maybe slightly bitter.

This came in a much larger bag than the previous one that I ordered, even though they are both 1.1 lbs or 500 grams. This makes it much easier to open, without spilling

I have complained before when buying items from Bulk Supplements on Amazon, that the expiration dates on the items indicate that rather than return old merchandise to the manufacturer, Amazon is eliminating old merchandise by sending them out to unsuspecting customers. Management of Bulk Supplements has informed me that it is not their fault, and that Amazon is failing to check the expiration dates before sending out Bulk Supplements merchandise to customers. Check the expiration dates when you receive them. Older Bulk Supplements products not only loose potency, but may cause stomach discomfort and more serious problems!

I am all for eating right and in the right proportions. I am also in agreement that vitamins help in a big way. For today, I am proofing the vitamin B2 also known as Riboflavin, by BulkSupplements. I buy the larger supply first because I am likely to make some batches that may not be palatable. Or my measurements were way off and I have to abandon the treats. I bought the B2 to help with migraine headaches as well. I also make cakes, cookies, tarts and a variety of blender drinks. I fortify the mixes with vitamins as needed. This product is a powder and is easy to measure. The taste is rather neutral and easily mixes with other flavors. The color is very orange like some spices. I highly recommend the products from BulkSupplements. The purity and consistency of the powders are very important to me. Each bag comes with a Lot number for tracking, if you are inclined to do so. On another day I will try to mix this as a topical cream. Good luck and live well.

I started taking this to fix migraines after I read in a medical journal about studies that showed it can help long-term to reduce or eliminate migraine. I've been dealing with migraine with severe vomiting for over 20 years. This seems to be working. I have even reduced the pain of migraine by taking extra when one is coming on. This is part of my "mito cocktail" of supplements with daily Ubiquinol and Riboflavin as the cornerstone and L-Carnitine added during a flare or crash. I dump 1/4 teaspoon of this onto 1/4 cup milk and immediately take a spoon and scoop it with some milk into my mouth. The remaining Riboflavin sinks to the bottom so I then stir that into the milk and drink it. This is usually followed by a little more milk stirred into the cup to get all the Riboflavin. This is the best way I have found to take it without encapsulating it. Make sure to rinse containers and spoons and wipe counter as this does stain everything yellow. One comment particularly about this product and bulksupplelements, and that is, they do not disclose their sources on the packaging, so I presume most of their raw materials are coming from China. China and India are the major suppliers of bulk vitamin substrates worldwide. What kind of lab testing is done on the raw materials when they receive them to ensure purity? This is my main concern with the bulk supplement industry. Anyone can order bulk supplements from China or India and repackage them for sale to consumers. Large suppliers MIGHT have in-house HPLC equipment to test the raw materials themselves, but suppliers like bulksupplements most likely do not have the hundreds of thousands of dollars to invest in this equipment (much less the expertise to use it). This is one argument for FDA regulation over the supplement/vitamin industry, which is a pandora's box. Consumers need to be aware of the contamination issues with supplements and the lack of regulation and not trust everything that is labeled. I took the risk when I ordered this bulk supplement, knowing these things.

Very happy with purchase

Product is great. Pouch it comes in, not so much. Upon opening the pouch, I noticed that the resealable section was full of B2. I scraped as much out as I could and thought I had closed and sealed it properly. I triple checked. It had not sealed properly and I ended up sitting on a yellow bed looking like a 6 foot oompa loompa. This seems to be a consistent issue of their pouches as I have had this happen with a couple of other purchases of theirs. Really frustrating as a lot of their products come in such portion sizes that they can be used for years, but are also highly sensitive to the elements so aren't much use if the pouch isn't sealing properly. Would recommend adding a desiccant sachet and checking the correct RDI as the company has a habit of suggesting much higher amounts than the average RDI.
