What does a homocysteine level of 65 mean? Are there any symptoms associated with this level?

A homocysteine level of 65 is considered high. High levels of homocysteine (an amino acid in your blood) are often related to a B vitamin deficiency. A homocysteine level >50 µmol/L may damage the lining of your arteries and can increase your risk of heart disease, blood clots, stroke, and heart attack [

]. High homocysteine is also associated with a greater risk of dementia and osteoporosis [

].

High homocysteine typically does not cause any symptoms in adults; however, if it’s related to a vitamin B deficiency, you may experience the following symptoms:

• Pale skin

• Fatigue

• Weakness

• Tingling hands, arms, legs, or feet

• Mouth sores

• Dizziness

• Weakness

• Changes in mood

• Swelling of the tongue (folate deficiency)

• Older age (homocysteine levels can increase as you get older)

• Menopause

• Being male (men usually have higher homocysteine levels than women)

• Drug and tobacco use

• Drinking 4 or more cups of coffee a day

What to do if your homocysteine level is 65?

Increasing your intake of folic acid (folate), B6, and B12 from foods may help lower your homocysteine level naturally. Some good dietary sources include: 

• Folate: Green leafy vegetables, asparagus, fruits, fortified bread and breakfast cereals, lentils, chickpeas, and beans

• Vitamin B12

  : Sardines, clams (including the broth of boiled clams), tuna, trout, beef, milk, and fortified foods like breakfast cereal and nutritional yeast

• Vitamin B6: Tuna, beef, fortified cereals, milk, chickpeas, chicken, and eggs 

Limiting your coffee intake to 3 cups or less/day, moderating your

alcohol intake

to <1-2 drinks/day, and quitting smoking may also help lower your homocysteine levels.

Medications and supplements used to improve homocysteine levels

In addition to making these diet and lifestyle changes, your healthcare provider may recommend certain medications or supplements to help lower your homocysteine level. 

Medications

• Levothyroxine: For high homocysteine levels caused by hypothyroidism, levothyroxine may be prescribed alongside a folic acid supplement to improve thyroid function and lower homocysteine levels [

  ].

• Betaine: Also known as betaine anhydrous, or trimethylglycine (TMG), betaine is often prescribed to individuals with homocystinuria along with B vitamin supplements to help control homocysteine levels [

  ].

Supplements

The treatment for high homocysteine caused by a B vitamin deficiency is vitamin B supplementation. The common dosage to treat low vitamin B is [

]:

• 50 mg/day of vitamin B6

• 1,000 µg (1 mg)/day of vitamin B12

• 2,400 µg (2.4 mg)/day of folic acid, split into three doses
