Warning- Quality has dropped!

Posted by Blue-Sky on January 1 2013 | Verified Purchase

Jarrow has changed the formula and it doesn't work so well any more.

Thanks for your feedback!

I really like Jarrow products, typically. But this made no difference, when cheaper formulas did. I read other reviews. Since July, other customers have remarked the formula (and bottle) have changed.

Thanks for your feedback!

Not so thrilled.

The Methyl B12 I have used in the past was small, cherry flavored, and didn't contain xylitol. This stuff, not so much - it's huge pills/logenzes, lemon-flavored, and has xylitol. I won't be buying it again. On the good side, I lucked out to have ordered powdered L-Lysine (in the jumbo can!) during one of your buy one/get one free sales the last time, and was totally delighted with it. Reordered, and missed the sale, but it's still a great product. One out of two's okay, I guess....

Thanks for your feedback!

This Product was no use to me as it gave me a Severe reaction upon taking it, which included severe sleepy/drowsiness, mental blanking and dizziness, perhaps i could not tolerate it due to the Methyl and i will be purchasing the Hydroxocobalamin next to see if that does any better. Despite that the Shipping from iHerb was great though, Thank you.

Thanks for your feedback!

No way!!!

It contains Xylitol which really irritates the bladder. Be cautious about this product!!!

iHerb gave me an expired good!

Posted by runsiman on December 10 2016 | Verified Purchase

I did not check the expiry date and stored the good in the cabin for about 2 months after receiving it. When I used it, I found that the expiry date is 10/13 !!!! It is unbelievable!!! How come iHerb gave me a expired good?!! I wrote to Jarrow to check the expiry date, but no reply from them. Lot no. 56799J16.
