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"
Vitamin D supplements are incredibly popular, but whether vitamin D supplements should be taken during pregnancy and at what dose is still debated, and studies have had conflicting results.

Another study not finding benefits from taking supplements - this time older men taking vitamin E and selenium supplements to see if it prevents dementia and Alzheimer's disease. The men (average age 67.5 years) were randomly assigned to take either vitamin E (400 IU) or selenium (200 µg), both supplements, or a placebo daily for over ...continue reading "Vitamin E and Selenium Supplements Don’t Prevent Dementia"

It appears that eating foods rich in calcium has protective effects against kidney stones, but taking calcium supplements may result in kidney stone growth. On the other hand, vitamin D may prevent kidney stone formation. Reviewing studies over the past few ...continue reading "Calcium Supplements and Kidney Stones"
Once again, a study finds that a supplement has no benefit - here omega-3 supplements did not slow cognitive decline in older adults. On the other hand, studies find that eating foods with omega-3 fatty acids (such as fish) has beneficial health effects. Regular consumption of fish is associated with lower rates of age-related macular ...continue reading "Eat Fish, Not Fish Oil Supplements"
More details are needed about this specific research, but this has been said before: foods are good, but supplements can be problematic. Here extra vitamins and minerals are linked to higher rates of cancer. From Science Daily: Excessive use of dietary supplements linked to increase cancer risk While dietary supplements may be advertised to promote ...continue reading "Supplements Linked to Higher Cancer Risk?"
There have been a number of studies over the years finding environmental links to testicular cancer (such as some pesticides, smoking, and endocrine disruptors). Now another one - muscle-building supplements with creatine and androstenedione . From Science Daily: Testicular cancer link found for muscle-building supplements Men who reported taking muscle-building supplements, such as pills and ...continue reading "Muscle Building Supplements Linked to Testicular Cancer"
Macular degeneration is a feared condition, so this study finding a link with calcium supplements and age-related macular degeneration in those 68 and older is a bit alarming. However, it shows association, not causation, because it looked at people only one time. But once again supplements are looking suspect. Another reason to stick with whole ...continue reading "Calcium Supplements Associated With Macular Degeneration"
