iHerb Customer Reviews

Great active formula

Posted by iHerb Customer on Feb 15, 2018 | Verified Purchase

One of the few excellent B formulas out there because all the vitamin forms are active - especially important with folate as many people can't tolerate the synthetic folic acid. It's best to store it in a climate-controlled place, though, because it's very sensitive and can go bad quickly if left somewhere too hot, for example.

Thanks for your feedback!

Doctor's Best B complex has B12 as methly....which is better to absorb. urine is bright yellow ather taking the pill but that is normal due to B2 going out :)

Waking up fresh

Posted by Beauty by ADD on Jan 28, 2018 | Verified Purchase

Have used it every night for a month now, will be repurchasing. Helps me get up in the morning feeling refreshed, even if I've had only 4 hours of sleep. I really feel energized and overall a sense of well being and clarity. No morning drowsiness.
