If you have diabetes, maintaining healthy circulation is important for overall health, including sexual function. However, no vitamin has been proven to specifically restore circulation or “intimate wellness” on its own. If you come across articles making strong claims, they’re often promoting supplements.
Three vitamins that are commonly discussed in relation to these issues are:
- Vitamin D
- Low vitamin D levels are more common in people with diabetes.
- Some studies suggest that correcting a deficiency may support blood vessel function and overall health, but evidence that it directly improves circulation or sexual function is mixed.
- Vitamin B12
- People taking metformin for type 2 diabetes can develop vitamin B12 deficiency.
- Treating a deficiency may help with diabetic nerve damage (neuropathy), which can affect sensation and contribute to sexual problems.
- Supplementation is most beneficial if you are actually deficient.
- Vitamin C
- Vitamin C is an antioxidant that supports blood vessel health and collagen formation.
- While it contributes to normal vascular function, there is no strong evidence that taking extra vitamin C improves circulation or sexual function in people who already get enough.
Other nutrients sometimes mentioned include vitamin E, folate, and the amino acid L-arginine, but the evidence for improving diabetic circulation or sexual function is limited or inconsistent.
What has the strongest evidence?
For people with diabetes, the interventions most likely to improve circulation and intimate wellness are:
- Keeping blood glucose well controlled.
- Managing blood pressure and cholesterol.
- Regular physical activity.
- Not smoking.
- Maintaining a healthy weight.
- Treating vitamin deficiencies if testing shows they are present.
- Discussing persistent erectile dysfunction or sexual concerns with a healthcare professional, as they may indicate underlying blood vessel disease and there are effective treatments available.
If you’re considering vitamin supplements, it’s a good idea to ask your healthcare provider whether you have any deficiencies or whether a supplement is appropriate, especially since some vitamins can interact with medications or be unnecessary if your levels are already adequate.
