We conducted a randomized, double-blind study to see if vitamin B complex could help older adults with nighttime leg cramps. Over three months, participants reported their cramp frequency and intensity.
The results were encouraging—86% of those taking vitamin B complex saw significant improvement, while the placebo group showed no notable changes. This suggests that vitamin B complex is a promising and safe alternative to traditional treatments like quinine, which can have unpleasant side effects.

Limited evidence for vitamin B effectiveness
We explored various treatments for leg cramps during pregnancy, including vitamin B complex. In our findings, oral vitamin B appeared to reduce the frequency and intensity of leg cramps in a small study involving 42 women.
However, the overall evidence was inconsistent and of low to very-low certainty due to design limitations and the small size of trials. Consequently, it's challenging to determine the real effectiveness and safety of vitamin B and other interventions for this common issue.

Improved sleep quality

My mind is clearer now. Approximately 15 years ago, when I experienced foggy thinking, I began taking vitamin B12. After finishing one bottle, my clarity improved. At that time, I was in my mid-40s. I believe it was the vitamin B12 that helped, particularly as I also struggled with neuralgia, leading to shaking and tension in my legs at night, disrupting my sleep due to restless leg syndrome. This B12 has proven effective. I tried various products but chose Jarrow due to its high purity, excellent quality, and palatable taste. This product has been beneficial in numerous respects.

Effective for cramps
I prescribed iron with vitamin B12 based on subscriber reviews, aiming to normalise low ferritin levels of 23. This drug receives high praise and I plan to continue using it. The leg cramps have ceased.
