What Supplements Do I Need?

This post started off with doing some research on PubMed on what studies have actually been conducted into what supplements I might need. The result was total confusion. Some studies say that vitamins may prevent this or that, while other studies say that the same vitamins cause this or that. So, I ended up totally confused. I trained as a pharmacist, and have learned a bit about the macro- and micronutritional needs of my body over the years, so I can only imagine how confused everyone else must be.

A few years ago now I started taking vitamins produced by a company called USANA. I like these because they are produced in a FDA-certified facility, and are backed by a lot of research. I also like them because they have kept me healthy even though I have had a lot of stress in my life. The range of products they have is impressive, but a little while ago they introduced a True Health Assessment that allowed me to assess just what products I needed. Whether I take them or not is up to me, but at least I have a good starting point. The really good thing about the True Health Assessment is that it is free. The products are not, and I do have to say that if you decide to order products after your assessment, I will receive a commission (thank you!). Read the rest of this entry

Is Flaxseed Good for You?

I was asked this question the other evening, so I had to do some research. The questioner was interested in a possible use for cancer. Obviously, we cannot say that anything will cure cancer. However, asking if a product will help is a good question. This post is the result of my initial research.

So what exactly are lignans? My training as a pharmacist tells me that they have a very complex chemical structure, which I am not going to repeat here. Lignans are found in many plant products, although the greatest amounts are found in flaxseed and sesame seeds. The active ingredient is called secoisolariciresinal diglucoside, which usually gets shortened to SDG. SDG is broken down in the body, where it reacts with special structures called estrogen receptors (they come to life when the hormone estrogen becomes attached to them). This SDG is what has been investigated for possible anticancer effects in a number of clinical and animal studies.

Some types of cancer may respond to increased eating of flax seeds, but much of the research that shows up on PubMed (an index of articles that discuss treatments for diseases) is in mice or rats. Whether the findings in humans will match those in animals remains to be seen. The particular types of cancer that have been investigated include breast, colon, prostate, and skin. It appears that taking flax seed or that SDG that we talked about above, may be best in the very early stages of cancer, but again don’t stop taking the medicine that your doctor prescribes if you have been diagnosed with any of these diseases.

A recent study, published by Dr. Hijova and colleagues, from Safarikiensis University in Slovakia, was particularly interesting, so I took a look at the full article. These researchers gave rats a high-fat diet and then gave them a prebiotic alone or in combination with horse chestnut extract or flaxseed oil. Another group of animals got the prebiotic and both horse chestnut extract and flaxseed oil. What they found was that in the animals that got the treatments there was a reduction in concentrations of an enzyme that they say has been found to be increased in patients with colon cancer. There were also reductions in total cholesterol, triacylglycerols, and bile acids compared with animals that got only the prebiotic.

The design of this study doesn’t allow us to draw any conclusions about whether the same thing will happen in humans. The authors make a very valid point in their conclusion, however. That is that diet may be very important in prevention of disease, and the role of nutritional supplements, like flaxseed oil and horse chestnut extract, needs to be studied in the future.

Looking at the research that has been conducted that flaxseed or the oil that comes from the seeds may be helpful in improving the chances of medications working in a number of different areas. It appears that flaxseed may be good for you, with little risk of side effects. Of course, check with your doctor before taking flaxseed for any ‘medicinal’ purposes.
