Vitamin B12 helps alleviate sciatica
Vitamin B12 in low back pain: a randomised, double-blind, placebo-controlled study.
Directly addresses vitamin B12 efficacy
We conducted a double-blind, randomized, placebo-controlled study to explore the effectiveness of intramuscular vitamin B12 in treating low back pain, including cases of sciatica. A total of 60 patients between the ages of 18 and 65, all suffering from mechanical lumbago or sciatic neuritis, participated in the study over a period of time. Each patient had a solid medical history of back pain lasting from 6 months to 5 years, with significant pain intensity measured on a scale.

Throughout the study, both groups showed notable reductions in pain and disability. However, when we compared the active treatment with the placebo, the results favored vitamin B12 significantly; the differences were strikingly marked in measurement tools used for assessing pain and disability. Furthermore, the placebo group reported higher consumption of paracetamol compared to those receiving vitamin B12, indicating that this vitamin could effectively alleviate pain and the need for additional pain relief medications.

Overall, our findings support the potential of vitamin B12 injections in managing low back pain and sciatica for those without signs of nutritional deficiency.

Vitamin B12 aids nerve recovery
Comparative evaluation of the electrophysiological, functional and ultrastructural effects of alpha lipoic acid and cyanocobalamin administration in a rat model of sciatic nerve injury.
Mixed evaluation of benefits
We explored the regenerative and protective effects of vitamin B12 on rats with sciatic nerve injuries. In the study, 40 rats were divided into several groups, including a control group, a sham group, and groups treated with either saline, alpha lipoic acid (ALA), or vitamin B12. Each treatment lasted for 12 weeks following the nerve injury.

Our findings revealed that while vitamin B12 showed some positive effects on nerve recovery, particularly in reducing edema and improving myelination, ALA treatment outperformed it in functional recovery measures. We noted significant improvements in the sciatic functional index for ALA-treated rats compared to those receiving vitamin B12.

The study highlighted the importance of understanding both the structural and functional aspects of nerve recovery. Even though vitamin B12 contributed favorably towards recovery, the results demonstrated that ALA might be a more effective option for enhancing movement and functionality after sciatic nerve injury.

Pain relief achieved
It has been 7 months since I began taking vitamin B12 for my sciatica, which was initially so severe that I couldn't walk. After 4 months, the pain had almost disappeared, and now I feel no pain at all. I used to suffer from this hernia-related pain every day for nearly two years. I still take it daily after meals, as it’s a small capsule that's easy to swallow. I highly recommend it for anyone dealing with nerve pain!

Improved symptoms noted
I have suffered from sciatica due to spinal stenosis for over six months. Over-the-counter medications did not help. Upon starting this supplement, my symptoms improved significantly. The numbness and pain in my calf have nearly gone, leading to a more positive mood. The cute pink capsules make me feel better every time I take one.

Significant pain relief
The mother suffers from sciatica, and I am grateful for the significant improvement and pain relief she's experienced. The package size is perfect, and the number of capsules is plentiful. The taste and smell are acceptable, and I find the effectiveness to be excellent and noticeable.
