"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."

FAQ Minerals & Supplements: Best Way to Take Supplements

FAQ Minerals Deficiencies: Best Way to Take 

6. “What’s the best way to take supplements—at the same time each day or spread throughout the day? In one lot or in divided doses?”

The best way may depend on the specific supplement, on your personal life style and if you are taking medication. Start by reading the “Suggested Use” as written on the vitamin or supplement label to ensure best results.

First, Talk to Your Doctor or Pharmacist 

Talk to your doctor or pharmacist before buying or taking any vitamin supplement, especially if you have a medical condition such as diabetes, hypertension or heart disease. Taking a combination of supplements or using them together with prescription medications, can produce unexpected results, some of which could be life-threatening.


Often supplements instructions are fairly specific: take “with or without food”, “with food” or “on an empty stomach”. Some supplements give you the choice of taking the full dosage all at once and when to take it. Morning may be better for your stomach. But based on your reactions or side effects, you may determine bedtime better suits you. 

For best results, read the “Suggested Use” on the vitamin or supplement label.

Divide and Conquer

If taking a single dose multi-vitamin, it’s best to take it in the morning when your body does not have nutrients and requires additional energy in order to rise and then function. For best absorption, take with or close to breakfast so that it will be broken down, then digested with the food

Multiple dose vitamins are better absorbed or better utilized by the body if spread throughout the day.

Do a Little Research

The best time to take a supplement may depend on the specific supplement.

A case in point, take a look at the research on Vitamin D. The Cleveland Clinic found that vitamin D is best absorbed after your biggest meal, usually dinner. Research shows that those who take vitamin D after dinner display a boosted level of vitamin D in their blood, averaging 56 percent more than those who take it without food.

In another instance, research shows you should not take a Calcium supplement along with a multivitamin containing iron. The calcium may interfere with the iron’s absorption.

And while you take your multivitamin with breakfast, a supplement like Magnesium may be best taken in the evening, since Magnesium may support sound sleep.

For the optimum results, do some reading at the library or at a reputable website or two.

Talk to your doctor before taking any vitamin supplement, especially if you are on prescription meds. The combination can produce unexpected results.

Life Style Adjustments

You may have to adjust taking supplements to your particular life style, the demands of your job, your school schedule, etc.

For example, some instructions say to take the supplement in the morning. Others say in the evening, or at bedtime. ‘Morning’ normally means when you rise and get ready for your day, and evening means closer to bedtime. But what if you work the swing shift from mid-afternoon to midnight? In this instance, your “morning” (when you rise and get ready for your day) may be one o’clock in the afternoon, and your ‘evening’ may start at 2 am.

And what if your work schedule often includes skipping or delaying a meal? Taking equally divided doses throughout the day may become erratic. So, it may work out better for you if you take all your vitamins or supplements in the morning before you go to work.

Try to be Consistent

Since these are ‘natural’ substances and not prescription drugs, you usually don’t have to be overly careful about when you take them. But do try to be consistent from day to day.

FAQs: Mineral Deficiencies & Supplements for a Healthy Heart

FAQs: Mineral Deficiencies & Supplements for a Healthy Heart

A-Fib patients often look for non-drug approaches to ease or prevent the symptoms of their Atrial Fibrillation. Here we share answers to the most often asked questions about minerals deficiencies and the use of supplements.

1. Dementia: “I’m scared of getting dementia. Can the right minerals help? I’ve read about the link with A-Fib. What does research reveal about this risk?”

2. Vitamin D: “How can I tell if I’m lacking in Vitamin D? I’m concerned because Vitamin D deficiency has been tied to both A-Fib and Dementia. What is a normal level of Vitamin D?

3. PVCs and PACs: “I have annoying PVCs and PACs with my A-Fib. Are there natural remedies to reduce these extra beats and palpitations? My doctor says to ignore them.”

4. Nutritional Info: I tried to talk with my doctor about magnesium and other nutritional supplements. His response was ‘There’s no proof that they work.’ Why are doctors so opposed to nutrition as a way of helping A-Fib.

Related Question:What’s the best way to take supplements—at the same time each day or spread throughout the day? In one lot or in divided doses?”

Related Question:Where can I find reliable, unbiased research and information on specific vitamins and supplements? (I want an independent resource, not some site trying to sell me their products.)”

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

6. Iron levels: “I’m anemic. Is too little iron in the blood (anemia) a cause of Atrial Fibrillation? Any advice on how A-Fib patients can deal with iron deficiency?”

Related Question: Can excess iron in the blood (Iron Overload Disease, IOD) cause Atrial Fibrillation? How do I know if I have IOD? What can I do about it?

7. Chelate: “What does ‘chelate’ or ‘chelated formulas’ mean when talking about vitamin and minerals? Is it important?

8. Magnesium: “Regarding Magnesium, can supplementing and restoring Mg to healthy levels reverse my A-Fib? I’m about to schedule a catheter ablation. But if supplementing can cure my A-Fib, why do an ablation?

9. CoQ10  “Can I take the supplement CoQ10 while on Eliquis for Atrial Fibrillation? On your site it says CoQ10 could be helpful. But on my bottle of CoQ10, it says “do not take if you are on blood thinners.

10. Krill Oil: “I’m interested in the supplement, Krill Oil, that has natural blood thinning properties. I’m taking Eliquis for my risk of A-Fib stroke. Is It OK to take Krill Oil along with Eliquis?”
