According to research reviewed by Gram, combining vitamin B supplements with pain-relief medicine significantly improves foot pain relief compared to medicine alone. In a 201-person randomized controlled trial, the combination group experienced 2.87-point pain reduction versus 0.91 points for medicine-only, with substantially better walking ability and quality of life improvements.
Researchers tested whether adding vitamin B supplements to a common pain-relief medicine could help people with foot and ankle pain feel better faster. They studied 201 people with conditions like plantar fasciitis and arthritis in their feet. Half took just the pain medicine, while the other half took the pain medicine plus vitamin B for 4 weeks. The group taking both treatments experienced much greater pain relief and improved their ability to walk and function. This suggests that combining these two treatments might be a better approach for managing chronic foot pain than using the medicine alone.
Key Statistics
A randomized controlled trial of 201 adults with chronic foot and ankle pain found that those taking pain medicine plus vitamin B experienced a 2.87-point pain reduction on a 10-point scale over 4 weeks, compared to only 0.91 points for those taking medicine alone.
In the same study conducted across four South Korean hospitals, the combination treatment group showed a 9.94-point improvement in foot and ankle function compared to 2.97 points in the medicine-only group after 4 weeks.
Of the 201 participants enrolled in the study, 156 people (78%) completed the full 4-week trial, with the combination therapy proving particularly effective for people with plantar fasciitis and symptoms lasting longer than 3 months.
The Quick Take
- What they studied: Whether adding vitamin B supplements to a standard pain-relief medicine helps people with chronic foot and ankle problems feel better and function more normally
- Who participated: 201 adults (ages 19 and older) from four hospitals in South Korea who had foot pain from conditions like heel pain, foot arthritis, ankle arthritis, or nerve pain in the foot. About 156 people completed the full study.
- Key finding: People who took the pain medicine plus vitamin B had their pain drop by about 2.9 points on a 10-point pain scale, while those taking just the medicine had pain drop by only about 0.9 points. The combination group also showed much better improvement in walking ability and quality of life.
- What it means for you: If you have chronic foot or ankle pain, adding vitamin B supplements to your current pain medicine may help you feel significantly better. However, talk to your doctor before starting any new supplements, as this study was done in Korea and results may vary for different people.
The Research Details
This was a randomized controlled trial, which is considered one of the strongest types of medical research. Researchers randomly assigned 201 people with foot problems into two groups: one group received a pain-relief medicine called aceclofenac twice daily for 4 weeks, while the other group received the same medicine plus a vitamin B complex supplement, also twice daily. Random assignment means each person had an equal chance of getting either treatment, which helps ensure the groups were similar at the start. The researchers then measured pain levels, quality of life, and foot function at the beginning and end of the 4-week period to see which group improved more.
This research design is important because it allows researchers to determine whether the vitamin B actually caused the improvement, rather than just observing that people got better. By comparing two similar groups where only one difference existed (the vitamin B), scientists can be more confident that any differences in results came from the vitamin B, not from other factors like exercise or natural healing over time.
This study has several strengths: it was conducted at multiple hospitals, used random assignment to reduce bias, measured outcomes using validated scales that doctors use regularly, and had a reasonable completion rate (78% of participants finished). The study was also registered before it began, which is a sign of good research practices. However, the study only lasted 4 weeks, so we don’t know if benefits continue longer, and it was conducted only in Korea, so results might differ in other populations.
What the Results Show
The main finding was that pain relief was significantly better in the group taking both the pain medicine and vitamin B. After 4 weeks, the combination group’s pain decreased by an average of 2.87 points on a 10-point scale (starting at 6.95 and dropping to 4.08), while the medicine-only group’s pain decreased by only 0.91 points (starting at 5.99 and dropping to 5.08). This difference was highly statistically significant, meaning it’s very unlikely to have happened by chance.
Beyond just pain relief, the combination group also showed much better improvements in overall quality of life. Using a quality-of-life measurement scale, the combination group improved by 0.079 points while the medicine-only group improved by just 0.008 points. Additionally, when measuring foot and ankle function specifically, the combination group improved by 9.94 points compared to only 2.97 points in the medicine-only group.
When researchers looked at specific foot conditions, the combination therapy was particularly helpful for people with plantar fasciitis (heel pain), foot or ankle arthritis, and Morton’s neuroma (nerve pain in the foot). The combination was also especially effective for people whose symptoms had lasted longer than 3 months, suggesting it may be particularly useful for chronic, long-lasting foot problems.
Beyond the main pain measurements, the study found that people taking the combination treatment reported better overall health and well-being. They could walk better, had fewer limitations in daily activities, and reported improved mood and mental health compared to those taking just the pain medicine. These improvements in function and quality of life are important because they show the treatment helps people return to normal activities, not just reduces pain numbers.
This is one of the first studies to specifically test whether vitamin B supplements enhance the effects of pain-relief medicines in foot disorders. Previous research has suggested that B vitamins may help with nerve pain and inflammation, but this study provides stronger evidence by testing the combination directly in a controlled way. The findings align with earlier research showing that B vitamins can support nerve health and reduce inflammation, but this study goes further by showing they work better when combined with standard pain medicine.
Several limitations should be considered: First, the study only lasted 4 weeks, so we don’t know if the benefits continue or fade over longer periods. Second, it was conducted only in Korea, so results might be different for people in other countries with different genetics or lifestyles. Third, 45 people who started the study didn’t complete it, which could affect the results. Fourth, the study didn’t track whether people continued to improve after stopping the treatment. Finally, the study didn’t examine potential side effects or interactions with other medications people might be taking.
The Bottom Line
Based on this research, adding a vitamin B complex supplement to your current pain-relief medicine appears to significantly improve pain relief and function for chronic foot and ankle problems. This recommendation has moderate-to-strong evidence from this well-designed study. However, this should not replace medical advice—discuss with your doctor before starting vitamin B supplements, especially if you take other medications or have health conditions. The evidence is strongest for people with symptoms lasting more than 3 months and for specific conditions like heel pain and foot arthritis.
This research is most relevant for people with chronic foot and ankle pain lasting more than 3 months, particularly those with plantar fasciitis, foot arthritis, ankle arthritis, or Morton’s neuroma. It may also interest people who aren’t getting enough pain relief from pain medicine alone. However, people with certain health conditions, those taking blood thinners, or those with B vitamin sensitivities should consult their doctor first. This research is less relevant for people with acute (short-term) foot injuries or those whose pain is already well-controlled.
Based on this study, you might expect to notice meaningful pain reduction within 2-4 weeks of starting the combination treatment. However, individual results vary—some people may feel better sooner, while others may need the full 4 weeks. It’s important to continue taking the treatment as directed and give it adequate time to work. If you don’t notice improvement after 4 weeks, talk to your doctor about adjusting your treatment plan.

Want to Apply This Research?
- Track your daily foot pain using a simple 0-10 scale each morning and evening, noting which foot/ankle area hurts most. Also record your vitamin B and pain medicine intake to ensure consistency. This creates a clear record of whether the combination is working for you personally.
- Set daily reminders to take your vitamin B supplement at the same time as your pain medicine (such as with breakfast and dinner). This habit-stacking approach makes it easier to remember both medications and helps you track whether you’re taking them consistently, which is important for seeing results.
- Over 4 weeks, track not just pain levels but also functional improvements like how far you can walk, whether you can climb stairs more easily, or if you’re sleeping better. Create a weekly summary comparing your pain and function to the previous week. If you see improvement, continue the routine; if not, discuss with your doctor after 4 weeks about whether to adjust the treatment.
This research suggests vitamin B supplements combined with pain-relief medicine may help chronic foot pain, but it is not a substitute for professional medical advice. Before starting any new supplement or changing your pain medication, consult with your doctor or healthcare provider, especially if you have other health conditions, take blood thinners, are pregnant or breastfeeding, or have had allergic reactions to B vitamins. Results may vary between individuals. This study was conducted in Korea and may not apply equally to all populations. If your foot pain worsens or doesn’t improve after 4 weeks of treatment, seek medical attention to rule out serious conditions requiring different treatment.
