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.

Increased energy

The best blend of B vitamins I've tried! The bottle size is good, and I feel a boost in energy when I take them. They also helped with nerve pain in my legs when paired with Benfotiamine. I'm very satisfied and will continue purchasing from IHerb!

Relieved leg cramps
I bought this for my father-in-law, who suffered from muscle cramps. Since taking it, he's greatly improved and has more energy. I recommend taking it every two days as the dosage is quite high. Good quality!

I switched from another brand but haven't felt the benefits with this one. It doesn’t help with leg cramps like my previous choice did. The quality appears ordinary, and I might not repurchase.

Allergy risks

The dosage is very high, and I experienced allergies even though I'm not typically allergic. I take one capsule daily after breakfast, but I suggest caution due to potential high doses.
