 Hip Fracture Risk With Too Much B-6 (06/10/2017)
Hip Fracture Risk With Too Much B-6
A new study found that older men and women who took a high daily dose of vitamin B-6 had a 42% increased risk of hip fracture. Get the details in the "Vitamin B-6" section of the B Vitamin Supplements Review. Also, be aware that many supplements on the market contain the amount of B-6 used in this study, or more, in a daily serving! For help choosing a B-Complex or B-6 supplement that suits your needs without providing too much B-6, see our Top Picks among B vitamin supplements.
 POTS and Thiamin (05/24/2017)

 Cognitive Decline With Too Little B6 (02/03/2017)
Cognitive Decline With Too Little B6
A recent study among men and women in their 60’s found that those getting inadequate amounts of vitamin B6 in their diets had much higher rates of cognitive decline. Get the details in the "What It Does" section of the B Vitamin Supplements Review (which includes our tests of products) >>
 Side-Effect With B-12 (01/20/2017)
Side-Effect With B-12
Certain formulations of vitamin B-12 contain additional ingredients that can cause diarrhea and bloating in some people – particularly if taking more than one pill. An apparent case of this was reported to us this week. To help you avoid this, read the details in the "What CL Found" section of the B Vitamin Supplements Review (which includes our tests of products) >>
 Potential Risk with High B-12 (01/10/2017)
Potential Risk with High B-12
Among people who are malnourished, those with elevated vitamin B-12 levels in their blood were twice as likely to die when hospitalized as those with lower B-12 levels, according to a new study. The study authors suggest caution with inappropriate supplementation. For more details about the study, and vitamin B-12, see the B Vitamin Supplements Review >>
2016 Too Much Folate & Nerve Damage (10/22/2016)
Too Much Folate & Nerve Damage
One quarter of American men and women have a gene variation which puts them at higher risk of nerve damage if consuming too much of folate (vitamin B-9) daily, according to a new study. Considering that most older Americans consume more than this amount (largely due to excessive supplement use) this should be a warning to many. For more details, see the "Folate" section of the B Vitamins Review >>
 Biotin Caution (08/20/2016)
Biotin Caution
Very high-doses of biotin (vitamin B-7) can cause misleading laboratory results and lead to unnecessary antithyroid treatment, according to a new report. For details, see the Biotin section of the B Vitamins Supplements Review >>
2015 How Vitamin B-12 Causes Acne (06/27/2015)
How Vitamin B-12 Causes Acne
Vitamin B-12 is a critical nutrient and many people, particularly those over 50, should supplement with B-12 to avoid deficiency. However, at doses higher than those used to prevent deficiency, B-12 may occasionally trigger acne. A new study appears to explain the B-12/acne connection. For details, see the "Cobalamin (B-12)" section of the B Vitamin Supplements Review >>
 Niacin Reduces Skin Cancer (05/16/2015)
Niacin Reduces Skin Cancer
A recent study suggests that high-dose niacin (vitamin B-3) may reduce the risk of developing certain types of skin cancer. A closer look at the study, however, raises questions about its relevance to people in North America. Get the details, as well as more information about niacin and our product test results & comparisons, in the B Vitamin Supplements Review >> 
 Folic Acid Reduces Risk of Stroke (03/15/2015)
Folic Acid Reduces Risk of Stroke
A large study in people taking blood pressure-lowering medication found that the addition of a daily folic acid (vitamin B-9 or folate) supplement significantly reduced the chance of having a stroke. This benefit is most likely to occur among people whose blood levels of folate are low. More details, including dosage and's test-based quality ratings of folic acid supplements, are found in the B Vitamin Supplements Review >>
2014 Do B Vitamins Boost Memory? (11/16/2014)
Do B Vitamins Boost Memory?
This week, a study was reported in the media suggesting that taking vitamin B-12 and folic acid does not help with memory. But a closer look at this and related studies shows a benefit for some people. Get the details, plus our tests and comparisons of B-vitamin supplements, in the B Vitamin Supplements Review >> 
 High-Dose Niacin with Statins Not Worth It (07/19/2014)
High-Dose Niacin with Statins Not Worth It
Further evidence was published this week showing that the addition of high-dose niacin (vitamin B-3) to cholesterol-lowering treatment with statin drugs provides no worthwhile benefit and appears to increase the risk of adverse side events. For details, see the Review of B Vitamin Supplements and Energy Drinks >> 
2013 B-12 Deficiency and Acid Inhibitors (12/14/2013)
B-12 Deficiency and Acid Inhibitors
A large, new study found the risk of vitamin B-12 deficiency to be significantly higher among people taking proton pump inhibitors (e.g., Prevacid, Prilosec) or H2-blockers (e.g., Pepcid, Zantac) than among those not taking these medications. The drugs reduce acid production in the stomach, but acid is needed to release B-12 from foods, so deficiency can occur. B-12 supplements can help because acid is not needed for their absorption. For details -- and our reviews of supplements with vitamin B-12 -- see the updated B Vitamin Supplements Review >>   

Other supplements which should or should not be used with these medications are discussed in the Proton Pump Inhibitors article, which is part of the extensive Drug Interactions section of our website (where you can look up interactions for other drugs you may be taking.) 

 B Vitamin Supplements for Stroke? (09/21/2013)
B Vitamin Supplements for Stroke?
A review of 14 clinical studies suggests that B vitamins may help prevent stroke. However, a deep reading of the report shows the benefit to be slight, at best.  For details about the study, other uses of B vitamins (including B6, B-12, folic acid, niacin and complexes), and tests of these supplements, see the B Vitamin Supplements Review>>  
2012 Higher Vitamin Level May Slow Cognitive Decline (12/16/2012)
Higher Vitamin Level May Slow Cognitive Decline
An 8-year study of people in their 70's found that cognitive functioning (memory and other mental skills) declined faster among those with lower blood levels of vitamin B-12 compared to those with higher levels. Particularly surprising was that 40% of the people in the study fell into the lower B-12 group, many of whom had levels which would not normally define them as deficient in B-12. This and other recent studies suggest a role for vitamin B-12 in minimizing cognitive decline in older people. For details, see the updated B Vitamin Supplements Review. More >>
 B Vitamin May Lower Blood Pressure (05/20/2012)
B Vitamin May Lower Blood Pressure
According to a new study, approximately 10% of the population is genetically prone to high blood pressure which may respond dramatically to a low dose of riboflavin (vitamin B-2). Read the update to the B Vitamin Supplements Review for details, including the dose used and amount of blood pressure reduction achieved. More >>
 B-12 and Folic Acid for Memory (01/08/2012)
B-12 and Folic Acid for Memory
Small but significant improvements in short and long-term memory were found to occur in older people (aged 60 to 74) given modest daily amounts of vitamin B-12 and folic acid. But don't expect immediate results. Improvements were seen only after 2 years of supplementation. See the update in the B Vitamins Review for the dosage used, as well as our ratings of supplements with vitamin B-12 and folic acid.
2011 B Vitamins May Help Memory (10/30/2011)
B Vitamins May Help Memory
A recently published study of individuals aged 70 years or more with mild cognitive impairment found that a daily dose of three B vitamins (folic acid, vitamin B-12, and vitamin B-6) over 2 years appeared to slow cognitive and clinical decline, particularly in those who started with elevated levels of plasma homocysteine. See the B Vitamin Product Review for details including the dosage used.  More >>
 Women-Vitamin Study - Key Points (10/12/2011)
Women-Vitamin Study - Key Points
You may have heard this week about a new study which found a higher risk of death among women who used certain supplements. It’s a complicated study, but we've summarized some key findings. Bear in mind that only white women ages 55 to 69 were enrolled in the study and they were followed for 22 years.

Those taking calcium supplements had a 3.8% reduced risk of death. The calcium benefit ended, however, when taking more than 900 mg per day from supplements. It's worth noting that experts suggest many older women who take calcium supplements may not need to -- see the Calcium Supplement Review for more.

The mineral most strongly associated with an increased risk of death was iron, which showed a risk increase of 3.9% -- and the risk increased as the dose increased, particularly over 50 mg per day. However, the study grouped dosages of under 50 mg together, making it hard to determine the risk of low dosages of iron, such as those in many multivitamins. However, there is very little reason why a postmenopausal woman should be taking iron -- see the Iron Supplement Review for more.

Although not as statistically meaningful, other supplements were associated with the following increases in the risk of death during the study: multivitamins (2.4%), vitamin B6 (4.1%), folic acid (5.9%), magnesium (3.6%), zinc (3.0%), and copper (18.0%). An abstract of the study is online.

The bottom line: Don't take a supplement you don't need. If you want to know how much of each vitamin and mineral you need from your total diet and how much is too much, see our chart at
 Niacin Concern Stops Cardiovascular Study (05/31/2011)
Niacin Concern Stops Cardiovascular Study
A clinical trial using high dose niacin (vitamin B3) was recently stopped by the National Institutes of Health due to lack of benefit and a small increase in strokes. Patients in the study had cardiovascular disease and were already taking a statin drug to keep LDL ("bad") cholesterol levels low. The addition of high dose niacin was intended to increase HDL ("good") cholesterol, reduce elevated triglycerides, and, most importantly, reduce the risk of heart attacks and stoke. For more information, including the amount and type of niacin used in the study and additional information about niacin and niacin supplements, see the B Vitamin Supplements ReviewMore >>
 Does folic acid affect the risk of colon cancer? (05/09/2011)
Does folic acid affect the risk of colon cancer?
Supplementation with higher amounts of folic acid (vitamin B-9) has been shown to increase the risk of prostate cancer, but its effect on the risk of colon cancer has been unclear. A new study found no increase in colon cancer due to folic acid supplementation. But if you supplement with folic acid, be careful. See the B Vitamin Supplements Review for more >>
