Plantar fasciitis is a common cause of pain in the sole of the foot. It occurs when the plantar fascia is overstretched and develops tears. Sometimes this can result from too much walking or running, and other times it may be due to poor nutrition.

What Deficiencies Cause Plantar Fasciitis?

A deficiency in magnesium, calcium, vitamin D, and multiple B vitamins (vitamins B1, B6, and B12) may cause this type of foot pain. Other compounds like methylsulfonylmethane (MSM) and vitamin C are also important for the body. These nutrients possess anti-inflammatory properties that prevent the formation of plantar fasciitis.

Can a Lack of Vitamin B12 Cause Foot Pain?

Foot pain is the product of a variety of factors, including trauma, underlying medical conditions, injury, tightness, etc. There are also claims that low levels of vitamin B12 can cause similar foot pain.

Generally, vitamin B12, also known as cobalamin, has a widespread effect on the body - with symptoms ranging from weakness and fatigue to cognitive impairment like memory loss.

In addition, the vitamin has a significant impact on the foot, with symptoms comparable to that of peripheral neuropathy. Research suggests that low levels of vitamin B12 can cause a burning sensation in the soles, heels, or pads of your toes. Other indications of a vitamin B12 deficiency include numbness in the limbs or feet, balance issues, mouth ulcers, and vision disturbances.

Apart from causing foot pain, vitamin B12 can also exacerbate plantar fasciitis. When a deficiency of this nutrient is suspected, it's always best to present your symptoms to a medical practitioner. Your doctor will perform tests to determine if you have a vitamin B12 deficiency.

Afterward, you'll be advised on the best plantar fasciitis treatment. Your physician is highly likely to recommend taking vitamins for your plantar fasciitis - most importantly, vitamin B12. To bring this level back up, your doctor will suggest the best supplement for your needs. There are many naturally-derived supplements on the market which are highly effective. But just as effective is a diet rich in fish, eggs, meat, and dairy products.
