We sought to understand how intramuscular vitamin B12 could help alleviate low back pain in patients with mechanical lumbago. In a rigorous study involving 60 participants, we compared the effects of vitamin B12 to a placebo.
Our findings indicated that those receiving the vitamin reported significantly less pain and disability, as measured by a visual scale and disability questionnaire. Notably, those on vitamin B12 also used less paracetamol than the placebo group.
Overall, our study confirmed that vitamin B12 can be effective for treating low back pain without nutritional deficiency.

This study evaluated the effects of intramuscular methylcobalamin injections on chronic low back pain.
In a rigorously designed double-blinded, randomized controlled trial, 60 patients were divided into treatment and placebo groups.
We observed significant improvements in pain and disability scores among those receiving methylcobalamin compared to the placebo.
Additionally, the treatment was found to be safe, with only minor side effects reported.

Vitamin B complex aids back pain relief
We examined how well celecoxib and a combined vitamin B complex worked for people experiencing lower back pain, comparing them with meloxicam.
Our findings indicated that celecoxib, especially when paired with Neuromultivit (a vitamin B complex), showed improved effectiveness in relieving both acute and chronic back pain.
Interestingly, while meloxicam offered similar initial pain relief, celecoxib was found to be superior for long-term recovery and quality of life improvements.
This suggests that adding vitamin B to treatment could enhance outcomes for those suffering from chronic lower back pain.

Combination therapy shows effectiveness
We set out to explore whether a rehabilitation program combined with specific supplements could effectively treat sciatica in young patients. Our study involved 128 individuals who were divided into three groups: one receiving both rehabilitation and supplements, one only with rehabilitation, and one with only supplements.
After treatment, the group with both rehabilitation and supplements showed significant improvement in pain relief and overall quality of life compared to the others. While the supplement-only group didn’t perform as well, this combination approach proved beneficial, particularly in reducing pain and enhancing stability.

We explored how effective vitamin B complex, alongside nonsteroidal anti-inflammatory drugs, is in treating back pain. Our study involved 70 patients divided into two groups, one receiving a vitamin B complex blend and the other a different pain relief combination.
Both groups showed improvement, but the first group experienced a clearer reduction in pain levels over time. By the third visit, they reported significantly less discomfort compared to the second group. Though both treatments were effective, the vitamin B complex showed a more pronounced impact on pain relief and patient satisfaction.

Vitamin B complex effective for pain
We examined how Dolo-Neurobion, a blend of essential B vitamins and an analgesic, affects acute lumbosacral pain. In a study of 53 patients, we found that this treatment yielded good to excellent results in 77.4% of cases, while 15.1% experienced moderate effects. The approach combined initial parenteral dosing with continuation through oral intake, and any necessary antibiotics were also used. Most notably, we observed no significant side effects, making Dolo-Neurobion a promising option for back pain relief linked to pelvic organ issues.

We explored how combining dexamethasone with vitamin B12 could impact early recovery from back and leg pain after a specific spine surgery called percutaneous endoscopic interlaminar discectomy (PEID).
In our study, patients were divided into two groups: one received only the surgery, while the other got epidural injections of both medications during surgery.
Results showed that the combined treatment significantly reduced pain and inflammation, leading to better early recovery outcomes. This suggests that using this combination might be a great option for patients undergoing this type of surgery.

Warning about dosage
276 people found this helpful
My first purchase was based on high dosage, assuming more was better. I soon regretted this; I developed severe side effects including intense back pain, weakness, and liver discomfort. I learned that excessive doses of B vitamins can cause toxicity. These vitamins went straight into the bin, and I regret not being cautious.

We conducted a thorough multicenter study involving 418 patients to assess the combined effect of diclofenac and vitamin B1, B6, and B12 on back pain. Over two weeks, we found that more patients achieved complete pain relief with the vitamin combination compared to diclofenac alone.
Specifically, 53 patients on the combination ended treatment early due to sufficient relief, compared to 48 in the diclofenac-only group. The results also showed significant improvements in pain scores, especially for those with severe pain. While some side effects were noted, they were similar between both treatment groups.
