Can I take Folic acid and Glucosamine together?

Why this happens

Folic acid (a B vitamin) and glucosamine (an amino sugar) are processed by the body through different pathways. They do not compete for absorption in the gut, nor do they interfere with how the liver breaks down or the kidneys remove each substance.

What you should do

You can continue to take both supplements as directed by your healthcare provider or the product packaging. As with any supplement, if you notice any unusual side effects, you should consult your pharmacist or doctor.

Important precautions

Vitamin B12 deficiency (Pernicious Anaemia)

Folic acid can mask the symptoms of vitamin B12 deficiency. If you have B12 deficiency, taking folic acid alone can allow serious nerve damage to progress even though your blood count appears normal. Your doctor must ensure your B12 levels are checked before or during treatment.

Shellfish allergy

Many glucosamine products are derived from the shells of crustaceans. If you have a shellfish allergy, you must check the label for a vegetarian or synthetic version to avoid a potentially severe allergic reaction. Vegan or shellfish-free versions are available.

Diabetes

Glucosamine is an amino sugar and may affect blood glucose levels. If you have diabetes, you should monitor your blood sugar more closely when starting or changing your dose.

Food and drink warnings

Alcohol

It is best to avoid or strictly limit alcohol while taking folic acid. Alcohol interferes with the way your body absorbs and uses folic acid, which can make the treatment less effective. Chronic alcohol consumption is a common cause of folate deficiency.
