How is anyone sure if a vitamin works the way it’s supposed to? With B2, your urine should turn bright yellow. That’s why I’ve used this brand for 5 years.

    I was ordering already second time form this seller. First time I bought for $7.59, last time for $9.99. Both times arrived next day on Saturday. Doctor prescribed B2 for my 6 y.o. son 200 mg/twice a day. But problem was that we weren't able to find this vitamin anywhere in Winnipeg. The only one I found was in tablets and had bitter taste that makes impossible for kid to take it. No matter with what you're going to mix it. Or another impossible option is to order from composing pharmacy with any flavors, which going to cost us $96 per bottle/month! And no guarantee that this will be tasty, not just smell good. This one B2 is in capsules that make my little one no problem to swallow. No taste or smell, no more mixing and tears! The only wish I have is to find 200 mg dosage, but overall we can deal with taking two capsules of this one. I bought 4 bottles to have free delivery and this will be enough for 3 month. If our doctor will prescribe it for longer I will definitely buy from this seller again.

    4.0 out of 5 stars Limited results but decent synergy with taurine for my eyesight.
    Reviewed in Canada on December 16, 2018
    Verified Purchase
    I started taking B2 alongside taurine for mitochondrial function.

    The results have been limited with the B2. It has decent synergy with the taurine for my eyesight but had no impact on other things.

    Instead of taking this daily, I now take it once a week to maintain the synergy for my eyes. I notice a drop-off in eyesight after ~8 days so taking a pill once a week seemed like the ideal choice.

    About the pills themselves, they are capsules containing powder. I cannot swallow pills of this size due to a rather finicky swallow reflex so I have to cut it in half and mix the powder in with water. One capsule mixed into 300ml of water (make sure to mix it well) is tolerable and not difficult to stomach. You should eat something afterwards to help absorption. The taste is earthy; if you have ever drank the liquid extract of rhodiola rosea, it tastes like a mild version of that. Not terrible at all, just annoying to go through the process of splitting the capsule and mixing. The mixing takes a while because it doesn't dissolve extremely well.

    I'm hoping that once I add more supplements to my cocktail the riboflavin will start having more of an impact. For now, however, I have enough capsules for nearly two years with just one bottle. Decent value and I can't discount the worth of better eyesight.

    5.0 out of 5 stars Works wonders for keratosis pilaris
    Reviewed in Canada on January 7, 2023
    Verified Purchase
    It is the 3rd time I ordered it. I cannot even remember why I wanted to try this as a combo with my other seasonal vitamins and minerals. However, shortly after introducing B2 I noticed my keratosis pilaris was gone. I continued taking it ever since (about 1 yr now). My skin looks good, no scales no bumps and it is glowing. I searched about vit B2 and keratosis pilaris and found out this is a good remedy, not mentioned in most articles, though. Got so many compliments on my skin, and I am 54 yo. It works wonders and it was the only thing I did differently, before noticing the change. If I only new this all those years I struggled with the skin condition. Well... no need to be self conscious anymore, and hide my skin. I'll continue buying it. Started with 2/day and, after a few months, when my skin cleared, I reduced to taking 1/day, for maintenance and my skin stays the same. I hope someone finds this useful.
