Once again a study finds that taking supplements can be problematic. This time it's fish oil supplements for heart health. Researchers found that taking routine daily fish oil supplements was linked to an increased risk of atrial fibrillation, a heart rhythm disorder. Atrial fibrillation is linked to higher risk of stroke and death. The international ...continue reading "Fish oil Supplements and Increased Risk of Atrial Fibrillation"

Many people complain of frequent colds and upper respiratory infections. Perhaps even every month. This is an especially big problem for those suffering from chronic sinusitis, because every cold and sore throat also leads to a sinus infection. So a goal is to try to reduce the number of infections, and daily vitamin D supplements ...continue reading "Fewer Respiratory Infections With Vitamin D Supplements"

A recent study found that giving daily vitamin D supplements to children with severe asthma and low vitamin D levels did not prevent severe asthma attacks, reduce the time to an asthmatic attack, or enable the children to reduce the maintenance dose of an inhaled corticosteroid. Very disappointing! As of 2018, it is estimated that ...continue reading "Children With Severe Asthma Not Helped By Vitamin D Supplements"

Disappointing results from a large study of more than 18,000 adults that looked at whether daily vitamin D supplements for 5 years helps prevent depression. The Harvard Medical School researchers found that vitamin D didn't prevent depression or improve mood. The study was large (more than 18,000 adults over the age of 50), double-blind (no one knew ...continue reading "Study Finds That Vitamin D Supplements Don’t Prevent Depression"

Once again a study finds health problems from supplements. This time, researchers found that several bodies of evidence (the long-running American Nurses' Study and two studies in Norway) found a higher risk of hip fracture in postmenopausal women who took high doses of both vitamin B6  and B12. Interestingly, B12 alone seemed to not be ...continue reading "High Dose Vitamin B Supplements and Hip Fractures"

Eat real foods, not supplements. Study after study has found beneficial health effects from eating real foods, but not from taking supplements. Now another large study found similar effects - eating real foods was linked to a lower risk of death for any reason (all cause mortality) and death from heart disease (cardiovascular), which was ...continue reading "Getting Nutrients From Food (But Not Supplements) Linked to Lower Risk of Death"

A diagnosis of a lifelong progressive disease such as multiple sclerosis is one that everyone wants to avoid. So there is much speculation and research looking at what causes it and possible ways to avoid getting it. Some earlier research suggested that zinc  and iron may play a role (e.g., finding that zinc levels are ...continue reading "Mineral Supplements and Multiple Sclerosis"

Once again, recent studies found that eating real food (fish) is associated with health benefits, but taking a supplement (omega-3) isn't. Similar findings about fish versus omega-3 fatty acid supplements have also been found in other studies. Fish contains omega-3 fatty acids and many other nutrients - more than are found in supplements. The first study ...continue reading "Health Benefits Linked to Eating Fish, Not Supplements"

Another study has found that the most common vitamin and mineral supplements (multivitamins, vitamin D, calcium, and vitamin C), don't offer hoped for health benefits, and may actually carry some risks. This latest study was a review of other studies, and examined whether specific vitamins or minerals would  lower the risk of cardiovascular disease (including ...continue reading "Study Finds No Benefit From Most Supplements"

Once again, a study found an association between a worrisome health problem (intestinal polyps) with a dietary supplement (calcium), but no problems with eating the foods (calcium rich foods). The large multi-center study specifically looked at serrated polyps (SPs) because they are considered precursor lesions for colorectal cancer - that is, that while they are ...continue reading "Best to Eat Calcium Rich Foods, Not Calcium Supplements"
