    Great product! Shipping was free as a first-time customer, and while there are some delays in shipping due to it shipping from overseas, Vitamin B12 Direct was very helpful in keeping me apprised of delays and I was updated in a very timely manner.

    Is top quality product and even during Covid pandemic, customer service always was proactive with any delays.

    I have ordered my B12 several times from vitaminB12direct. My health insurance only authorizes 2 doses/month. I’ve been taking b12 due to surgery I had n 1976, which disrupted my body’s ability to adsorb b12. When I started getting neuropathy my insurance would not increase my b12 dosing. I read up on neuropathy and discovered high does b12 has been successful in treating neuropathy. Thanks to vitaminB12direct I have been able to use high dose B12 therapy, with my primary care physician’s oversight, and my neuropathy has improved by at least 80%! Their product is equivlent to what I get from the pharmacy, and the b12 levels my doctor orders has shown that my B12 levels have increased considerably, meaning the VitaminB12direct product is working as it should. And you can’t beat the price! Thank You VitaminB12Direct.
