Key Takeaways

Research on supplements for muscular dystrophy (MD) is limited, and no supplement has been proven to treat or reverse the condition.
Calcium and vitamin D are often recommended for people with MD, especially those taking corticosteroids, because these medications can raise the risk of bone loss. Other supplements like creatine, omega-3 fatty acids, and CoQ10 have been studied for their possible effects on muscle health and inflammation, but results are mixed and more research is needed.
Before trying any supplement, talking with your doctor or registered dietitian is an important first step, as some supplements can interact with medications, and your care team can help you find options that are right for your specific type of MD.

View all takeaways

Research on supplements for muscular dystrophy (MD) is limited. Whether they can be helpful depends on the type of MD you have and the treatments you’re on. Some supplements have been studied for their potential effects on muscle strength and function, fatigue, or nutritional deficiencies that may occur with MD.

No supplement has been proven to treat or reverse MD. However, your care team may recommend certain foods or supplements in addition to your treatment plan. We’ll explore what the research says about common supplements for MD and what to consider before taking them.

What To Know Before Trying Supplements

Supplements can include vitamins, minerals, and amino acids (protein building blocks). Some nutrients can help certain health conditions, but taking more than you need can cause side effects. Some medications may also interact with supplements, so always consult your doctor before trying them.

🗳️ Do you or your loved one take supplements for muscular dystrophy?

Yes, I take creatine

Yes, I take other supplements

I’ve tried supplements, but I’ve stopped

No, I don’t take any supplements

Research on supplements for MD may not apply to all types of MD. Symptoms, disease progression, and overall health can differ from person to person. These factors may affect how well a supplement is absorbed or works in the body.

Supplements vs. Nutrition Support Therapy

Supplements differ from nutrition support, which may be a part of MD care when someone has difficulty meeting calorie, protein, fluid, or nutrient needs through diet alone.

Nutrition support therapy is given through a feeding tube or intravenously (IV). It may be prescribed in more severe cases when food can’t be consumed, or when nutrients need to be supplied another way.

Calcium and Vitamin D: Established Care for Muscular Dystrophy

Calcium and vitamin D cannot treat MD directly, but they may be recommended for people who have low levels, low intake, or other risk factors for bone or muscle health.

People with MD may have reduced mobility, which can be a barrier to getting the regular sun exposure important for bone health.

For people taking corticosteroids, maintaining calcium and vitamin D levels is especially important because these drugs can increase the risk of bone loss. Calcium also helps your muscles work properly.

Dietary Calcium and Vitamin D

For people with Duchenne muscular dystrophy (DMD) or Becker muscular dystrophy, nutrition guidance emphasizes getting enough calcium, vitamin D, and other nutrients through diet.

Main sources of vitamin D include some mushrooms, fatty fish, and fortified foods. Your body makes vitamin D when you’re exposed to sunlight. Main sources of calcium include leafy green vegetables, dairy, and some grains.

Calcium and Vitamin D Supplements

Because people with Duchenne muscular dystrophy (DMD) are at increased risk of bone fragility, especially those who are taking long-term corticosteroid treatment, vitamin D supplementation is recommended for them.

In addition, people on corticosteroids may be recommended vitamin D and calcium supplements to prevent osteoporosis.

More research is needed on calcium supplementation in people with MD. Work with a nutrition provider to make sure you get enough calcium in your diet.

What the Research Says About Other Supplements

Research on other supplements for DMD and Becker muscular dystrophy is still limited. Some supplements have been studied for their potential effects on muscle health and inflammation, but the results vary. Here’s what some of the current research says about other supplements for MD.

Calcium-HMB

Beta-hydroxy-beta-methylbutyrate (HMB) is a compound the body makes when it breaks down leucine, an amino acid that helps build proteins. HMB is also available as a dietary supplement, in the form of calcium-HMB.

A recent animal study found that daily HMB supplementation showed improved activity and slower collagen breakdown in dogs with DMD. The study was small, and more research is needed to understand how this works in people with DMD.

Creatine

Creatine is a well-studied compound known for its effect on muscle health. It helps provide energy to muscle cells, and some people take it to build strength.

In people with DMD, some research suggests that taking 2 to 10 grams of creatine a day for two to four months may improve muscle strength and reduce fatigue. However, published studies have been small, and so far they haven’t consistently shown improvements in daily function.

Glycine

Glycine is another amino acid that has been studied as a potential supplement for DMD. In a study of mice with DMD, glycine supplementation reduced fibrosis, improved prednisolone effectiveness, and improved quality of life for DMD patients.

The results were similar to mice treated with prednisolone, a steroid medication that’s commonly used to treat DMD.

There is not enough human research to confirm whether glycine improves muscle function for people with DMD and what an appropriate dose would be. Researchers suggest that adding glycine supplementation to prednisolone treatment for DMD is likely safe, but more research is needed.

Omega-3 Fatty Acids

Omega-3 is a type of fatty acid that has shown benefits for various health conditions. A review of studies found that omega-3 supplementation can lower some inflammation markers. However, more research is needed to understand whether omega-3 fatty acids can help with muscle function in people with MD.

CoQ10

Coenzyme Q10 (CoQ10) is an antioxidant that helps cells make energy. It also protects cells from damage. Some research suggests it may help reduce muscle cell damage in MD. However, results are mixed depending on the type of MD and the form of CoQ10 used.

Safety Considerations

Before taking a supplement, talk with your doctors or registered dietitian. Some supplements can interact with medications or other supplements, and taking higher doses may raise the risk of side effects.

The U.S. Food and Drug Administration (FDA) does not determine whether dietary supplements are effective or safe before they are marketed. If you choose to use a supplement, look for products from manufacturers that follow the Good Manufacturing Practices (GMPs) and have been tested by trusted organizations. Your providers may also recommend brands or products they trust.

It’s especially important to use caution with supplements if you have other conditions like heart, kidney, or liver problems. These conditions can affect how your body uses and eliminates supplements.

Always discuss supplement use with your care team before you take them.

Questions To Ask Your Doctor

Knowing what to ask can also help your doctors provide care tailored to you. Before starting a supplement, consider asking your doctor or registered dietitian the following:
