I love Thorne products and P-5-P is an activated form of B6 and highly absorbable. I used to take a ionic P-5-P prescribed by my doctor as I have a condition which depletes my body in zinc and B6. This ionic vitamin had to be refrigerated and since I spend a good portion of my time traveling I was keen to find a stable source of good quality. This is it! I love Thorne products and this products really works for me. B6 is necessary for the synthesis of serotonin and dopamine (feel good hormones) as well as triptophan. Also highly important for digestion and so on. I highly recommend this product!

Thanks for your feedback!

Not For a Sensitized Nervous System

Posted by ReaCovery on Nov 19, 2015 | Verified Purchase

I bought these hoping I would be able to tolerate them. My nervous system is currently hyper-sensitized by protracted antidepressant withdrawal syndrome (PAWS). I was trying to increase my B6 and Zinc, thinking I may have pyrole disorder. I could tolerate the zinc fine, but not B6... not even this active form. All B6 including this one disrupts my sleep and increases daytime anxiety. So for now, this isn't for me. Maybe when I'm recovered. I do like the Thorne brand in general though.

Thanks for your feedback!

Great source of B6

Posted by iHerb Customer on Dec 13, 2010 | Verified Purchase

B6 is important for so many functions in the body and, from what I recall, it's the one B vitamin the body can't synthesize from other nutrients. Thorne is a little pricier, but I trust their purity and potency. Too much B6 can cause nerve damage so do your research.

Thanks for your feedback!

Reliable P5P

Posted by iHerb Customer on Feb 02, 2010 | Verified Purchase

I don't tolerate regular B6 very well, but need to take higher amounts to combat depression. This P5P has been a life-saver, and I'm thrilled that iHerb now carries it.

As my body has trouble accessing the B6 from the B molecule this has proved to be a great find.....

When I take enough of these I recall my dreams again and have a very deep sleep.

Excellent product

I was recommended to take this product for carpel tunnel problems. Need to take it along with some other supplements for 3 months, but so far it seems to help.

Best coenzymes vitamin B6

Posted by iHerb Customer on Aug 16, 2010 | Verified Purchase

I like Thorne Research's products w/o any harmful ingredients. Excipient free is always my best choice.
