"This book is incredibly complete and easy-to-understand for anybody. I certainly recommend it for patients who want to know more about atrial fibrillation than what they will learn from doctors...."

Pierre Jaïs, M.D. Professor of Cardiology, Haut-Lévêque Hospital, Bordeaux, France

"Dear Steve, I saw a patient this morning with your book [in hand] and highlights throughout. She loves it and finds it very useful to help her in dealing with atrial fibrillation."

Dr. Wilber Su Cavanaugh Heart Center, Phoenix, AZ

"Your book [Beat Your A-Fib] is the quintessential most important guide not only for the individual experiencing atrial fibrillation and his family, but also for primary physicians, and cardiologists."

Jane-Alexandra Krehbiel, nurse, blogger and author "Rational Preparedness: A Primer to Preparedness"


"Steve Ryan's summaries of the Boston A-Fib Symposium are terrific. Steve has the ability to synthesize and communicate accurately in clear and simple terms the essence of complex subjects. This is an exceptional skill and a great service to patients with atrial fibrillation."

Dr. Jeremy Ruskin of Mass. General Hospital and Harvard Medical School

"I love your [A-fib.com] website, Patti and Steve! An excellent resource for anybody seeking credible science on atrial fibrillation plus compelling real-life stories from others living with A-Fib. Congratulations…"

Carolyn Thomas, blogger and heart attack survivor; MyHeartSisters.org

"Steve, your website was so helpful. Thank you! After two ablations I am now A-fib free. You are a great help to a lot of people, keep up the good work."

Terry Traver, former A-Fib patient

"If you want to do some research on AF go to A-Fib.com by Steve Ryan, this site was a big help to me, and helped me be free of AF."

Roy Salmon Patient, A-Fib Free; pacemakerclub.com, Sept. 2013

FAQ Minerals Deficiencies: BCAA+G 

5. “The supplement BCAA+G helps builds muscle. Is it a natural remedy that could help my A-Fib? Are A-Fib patients BCAA-deficient?”

Branched Chain Amino Acids (BCAA) include the three amino acids leucine, isoleucine and valine. Along with L-Glutamine (+G), another amino acid, they’re critical to the repair and maintenance of strong muscles, including the heart―which is only a muscle after all.

Athletes and weight lifters use BCAA+G to build muscle, improve exercise performance and decrease post-exercise soreness and recovery time. BCAA+G also claims to increase nitrogen retention. If more nitrogen is consumed than lost, it means that muscle is being created. (I personally take BCAA+G after running and after working out at the gym.)

Our body doesn’t naturally manufacture Branched Chain Amino Acids. They’re essential nutrients that the body obtains from proteins found in food, especially meat, dairy products, and legumes (or through supplementation).

All of your muscles, including your heart, could suffer if you are BCAA-deficient.

I don’t know of anyone who is testing A-Fib patients to see if they are BCAA-deficient. (Heck, most doctors don’t even test for magnesium deficiency which is known to contribute to A-Fib.)

I can’t find any clinical research about BCAA and A-Fib. So, I’d be hard-pressed to draw any direct benefits from BCAA+G for curing A-Fib―except the following personal experinces from two A-Fib patients.

If you decide to try BCAA+G, talk to your doctor before adding it to your treatment plan. 

A-Fib.com Patients’ Experience with BCAA+G

In his personal A-Fib.com story, Harold Bosworth writes that Branched Chain Amino Acids (BCAAs) coupled with L-Glutamine (Gln or Q) got him out of Chronic (continuous) A-Fib after taking it for 2 days. He’d been in Chronic A-Fib for 3 years.

In another personal story, Tom Lisak wrote: “My doctor wanted to put me on Coumadin…I decided to try the “natural” approach…vitamins, herbs, chiropractic and acupuncture…all to no avail. Then I read Harold Bosworth’s account of his experience with BCAA + Gln.  I took a heaping teaspoonful twice a day and in 2-3 days, the A-Fib disappeared.” Read more of his story.

What this means to you: We can’t say that BCAA+G is going to cure your A-Fib. It may help your overall muscle health which in turn may also help the function of your left atrium. It’s worth a try, especially if you exercise a lot.

If you decide to try BCAA+G, talk to your doctor before adding it to your treatment plan. For recommended products and dosage, see my article, Natural’ Supplements for a Healthy Heart.
