Power Up with Vitamin B12

/in /by

The final supplement I’ll cover this week is vitamin B12, sometimes called the energy vitamin. Many vitamins are involved with energy production, but a lack of B12 can certainly cause problems with energy and other issues.

Vitamin B12 is also known as cobalamin and if you’re wondering, yes, this vitamin does include the mineral cobalt. There are two primary functions of B12 in the body. The first is to help reduce the chemical homocysteine to methionine while helping folate be converted into a usable form in the same reaction. Without enough B12, homocysteine increases inflammation in the body . . .

Do You Make Enough Coenzyme Q10?

/in /by

There’s one major difference between coQ10 and other vitamins, minerals, and nutrients such as omega-3s: we can produce coQ10 ourselves. The problem is that we may not produce all the coQ10 we need, especially as we get older.

CoQ10 is used in the production of energy from both carbohydrates and fat in the mitochondria of the cells. You remember mitochondria from science class; they’re often called the powerhouse of the cells. And coQ10 is the substance that’s used to produce that power. It’s critical in the steps where oxygen is used to produce ATP, the . . .

What You Need to Know About Omega-3s

/in /by

This week I’m covering basic information about three supplements.  One of my favorites and one I don’t ever leave home without is omega-3 fatty acids.

There are three basic forms of omega-3 fatty acids: eicosapentanoic acid or EPA, docosahexaenoic acid or DHA, and alpha-linolenic acid or ALA. The body cannot make omega-3 fatty acids, so they have to come from food and supplements. ALA is an essential fatty acid—the body can make EPA and DHA from it but not very well—so getting EPA and DHA from diet and supplements is critical.

EPA . . .

Why You Need to Supplement

/in /by

The author of the opinion article in JAMA recommended that physicians make their patients aware of the research that questions the effectiveness of supplementation, hence his title “Negligible Benefits, Robust Consumption” (1). In making that recommendation, he gives the precise reason why that’s a bad idea. As I said Thursday, the answer can be found in the data used in the original article in JAMA about supplementation use in the U.S. (2).

While the JAMA article focused on supplementation, it also included data on food . . .

Supplements: No Benefits?

/in /by

The opinion piece in the journal article was titled “The Supplement Paradox: Negligible Benefits, Robust Consumption” (1). The author is a well-respected physician who has written often about what he feels are the problems in the dietary supplement industry. He used the article I talked about Tuesday as a basis for his latest thoughts. Why would supplement use stay the same when research demonstrates that there are little to no benefits?

He raised three points. First, he suggests that people haven’t heard about the negative studies. I would debate that based on the questions I get about science . . .

Changes in Supplement Use

/in /by

I take dietary supplements, and so do most of the people I know. We’re not alone. Using data from the NHANES data in 1999 and 2012, researchers compared how many people used supplements and what type of supplements they used (1).

Close to 38,000 subjects were included in the study. The percentage of people using supplements remained fairly stable over the time span at 52%; what changed was the types of supplements people took. Multivitamin-multimineral (MVMM) dropped 6% from 37% to 31%. There were some increases: vitamin D supplementation (other than from MVMM) increased from 5.1 . . .

The Bottom Line on Green Tea Extract

/in /by

The Consumer Reports article on “15 Supplement Ingredients You Should Always Avoid” included green tea extract powder on the list. Paula and I have used it for a number of years, so I wanted to check out the research behind the potential health issues they claimed could happen to people who regularly use green tea extract powder as part of a supplement plan.

The problem is that the authors didn’t list any references. They had a document that listed their board of experts, the stores they shopped, and a list of criteria they used to select the ingredients; they . . .

Supplements You Should Avoid

/in /by

The second Consumer Reports article about supplements was “15 Supplement Ingredients to Always Avoid.” The best place to begin is with the list so here it is:

Aconite
Caffeine powder
Chaparral
Coltsfoot
Comfrey
Germander
Greater celandine
Green tea extract powder
Kava
Lobelia
Methylsynephrine
Pennyroyal oil
Red yeast rice
Usnic acid
Yohimbe

Along with the list, there was a column that gave claims and benefits of each along with a column of hazards ranging from mild irritation to death. To me, most of the items on the list were herbs I’ve never used and . . .

Are Supplements Making You Sick?

/in /by

Consumer Reports has been a go to source if you wanted to find out about purchasing a good automobile, toaster, oven, or other household product. Years ago they added health to their repertoire, including dietary supplements. In July they published a series of articles on the dangers of supplements. I’m going to talk about two of the articles this week.

The first article was provocatively titled “Supplements Can Make You Sick.” It began with a sad story about a premature baby, went on to talk about the dangers of using “unregulated” supplements that can contain illegal substances and even . . .

Drinking Your Phytonutrients: The Bottom Line

/in /by

To finish this series, I’ll briefly cover two recent research studies on coffee and tea, and then give you the bottom line and a recipe.
 
Research
Green Tea and Neuronal Mitochondria
The mitochondria are the powerhouses of the cells, and that includes brain cells. When they operate at peak activity, they provide our brains with the energy for learning and memory. The downside is that they produce many free radicals in the process, and if we don’t have antioxidants to quench those free radicals, it can cause a decline in mental function. Researchers have recently . . .
