With B12 being extremely difficult to absorb this product is ideal. Couple of sprays under the tongue twice a day will ensure that you keep your B12 topped up and will also assist in providing energy. I have no hesitation in recommending this product and it even taste great.

I have been using Advantage Vitamin B12 oral spray for three years now. I use the recommended daily dose of 500 mcg which is one spray. Due to a gut problem I was not absorbing well. I have Osteoporosis for which I took Bisphosphonates for 7 years. My bone density in my spine has usually decreased at each Dexa scan. The last scan showed that although there was no improvement the bone density had not worsened. My GP was very impressed. I also take other vitamins and minerals.Although the Vitamin B12 may not be entirely responsible for the outcome I am sure that is due to the fact that it is better absorbed via the spray method.I shall continue to use it for the rest of my life.

This is a fantastic vitamin b12 supplement. After having very low levels of B12 recorded after a few months of taking this every day my levels were high. It definitely does what it's supposed to do!

I started taking the Advantage Vitamin B12 about 2 weeks ago. I have Fibromyalgia (FM) and also Brachial Plexus Neuropathy which has gives me a lot of pain in my arms. I am not sure if it is the FM that is the cause of the nerve pain or the neuropathy or both but since taking the B12 there has been a marked reduction of pain in my arms especially the right one and my muscle strength has improved too. I am not sure but I think that the myelin sheath on the nerves which have been affected by FM and neuritis may have been healed through the B12 supplementation. I really like this product as it has no chemicals or additives which would cause me problems. The only downside to this product is tha ...(more)

I am very pleased with this. My mother had very low b12 levels but not low enough for the GP to agree to injections - she started using several sprays of this every day & a few months later when her GP tested her B12 it was at the higher end of 'normal' - so it obviously works very well! Her symptoms were loads better too.

I have been using this product for some time now with my GP's blessing due to the fact that I do not absorb well through my gut. I have osteoporosis and need to improve my bone density. I am hoping that I am absorbing sublingually but will not know until my next DEXA scan in 2014 whether or not it has helped. It is pleasant to take and has caused no side effects. It is good value for money.

I've been suffering from severe ME/CFS for over a decade. One of the best things that's helped me on my healing journey has been B12 injections as prescribed by a fantastic Private Doctor. When sublingual sprays came along she felt they were as good as the injections - and much to my relief they are! Then I found the Methylated form - this really helps me to keep going and keep my head clearer! Great product no sweetners or any other baddies which aggrivate my multiple allergies naturally tasty lasts for ages and I can feel that I get full absorbtion - so great value! I can't recommend this product enough!

Two years ago my dog was diagnosed with intestinal disease leading to a severe vitamin B12/cobalamin deficiency. The treatment was to inject him twice a week with B12. Not only was this painful and stressful but being the synthetic form he reacted badly to it. Searching for a solution to this nightmare I came across this spray. To be honest I really didn't think it would work. If it was that effective why hadn't my vet recommended it? All I can say is that this spray has been nothing short of a miracle. One spray in the morning and he has become a different dog. His B12 readings at the vet have returned "very high" and he has never had another injection. Friends of mine(the hu ...(more)
