Dear Friends and Valued Customers,
A little over a year ago, I first read about the amazing potential of the omega-7 fatty acid known as palmitoleic acid in a magazine article entitled "5 Health Breakthroughs You Should Know About", by Dr. Mehmet Oz and Dr. Michael Roizen, authors of the New York Times bestseller YOU: The Owner's Manual: An Insider's Guide to the Body That Will Make You Healthier and Younger. Naturally, I was intrigued when I learned about its benefits, and quickly went to work to make it available to our Swanson customers. As a result, I'm proud to introduce Provinal® Purified Omega-7 Concentrated Palmitoleic Acid to our Swanson® EFAs line of superior quality fatty acid supplements. Recently, I had the opportunity to talk with Dr. Roizen about the numerous health benefits of this remarkable breakthrough.
As always, I wish you the very best of health,
DR. ROIZEN: A few years ago, a researcher of some repute came to my office one day and showed me the effect of omega-7s on vascular health in animals. The researcher had a family illness and had to leave Cleveland, and asked me to carry on the research and development of omega-7s. I reviewed the data and they were so impressive, I asked Tersus Pharmaceuticals if I could help lead their scientific advisory board to see if supplemental omega-7s had significant benefits without significant side effects.
What's really unique about the omega-7s is that they actually raise levels of beneficial HDL, the "good cholesterol."
It has proven such a profile of benefits so far. They also help control hepatic fat—that's fat in the liver—and they promote beta cell activity to help your cells use glucose efficiently, which is very important for maintaining healthy metabolic function, especially as we grow older. These are fundamental physiological processes that can have a cascade of beneficial effects throughout the body.
DR. ROIZEN: Well, they haven't been studied much until recently and that's because there wasn't really a good source to use for research until Provinal® Purified Omega-7. All prior methods of sourcing omega-7s were either too expensive or came with an antagonist. What I mean by that is, for example, buckthorn—one of the richest natural sources of omega-7—also contains an unhealthy fat that counteracts the beneficial effects of the omega-7. Think of it this way: you wouldn't accept water with harmful contaminants; for the same reason, you want a purified omega-7 source without stuff that is likely to harm you. So to make an effective product out of buckthorn you have to isolate the omega-7, which is expensive to do from that source. Likewise, if you extract omega-7 from macadamia nuts, another source, it costs about ten dollars a pill. Well no one is going to study that because you're not going to have much of a market for it if it costs ten bucks just to make each pill. But with Provinal® Purified Omega-7 they developed an inexpensive method of isolating omega-7 from a fish source that also purifies it so that you don't get the antagonist with it as you would with some of the other sources. Provinal® Purified Omega-7 yields a minimum 50% concentration of omega-7 palmitoleic acid while keeping levels of antagonistic fatty acids below one percent. It's the only source of purified palmitoleic acid on the market today.
DR. ROIZEN: Salmon is a good source of omega-3s, but it doesn't have much omega-7 in it. Most of the omega-7 research has used intakes of 210 mg to 420 mg per day, which would be nearly impossible to obtain through dietary sources. And as I mentioned earlier, many omega-7 sources also contain high levels of antagonistic fatty acid, which you want to avoid, so it's important that you get a purified form. Only a few species of fish have sufficient concentrations of omega-7 to make an inexpensive yet reliable and effective supplement. Provinal® Purified Omega-7 is extracted from wild anchovies, which are caught off the coast of Peru and Chile.
DR. ROIZEN: Provinal® helps promote healthy HDL, the "good cholesterol" that actually helps clean out your arteries as it moves through. We've realized in the last few years that the overall cholesterol number isn't nearly as important as breaking it down into LDL and HDL, because the two have such different actions. When it comes to HDL, higher is better—so an HDL level of 60 versus one of 39 will make the average 55 year old woman four years younger, health-wise. The actual level of HDL is less important than its effect; the more active HDL is in removing LDL the better. Provinal® Purified Omega-7 appears to promote healthy levels and possibly even the activity of HDL.
DR. ROIZEN: We don't know for sure at this point. We could find no side effects at the 210 mg or 420 mg per day dosage. Studies have used as much as 1,500 mg per day with no negative side effects or drug interactions. Now, because it's derived from anchovies, it might not be suitable for people who are allergic to fish. However, thanks to its purified form it has been very well tolerated in studies, without the fishy taste or burp that people often experience with omega-3 fish oil supplements. When it comes to what's most effective, we don't know yet. We know that when we give more of it we get more of an effect. For the vast majority of people, 210 mg per day has substantial and important benefits, but 420 mg is even more effective. We don't know yet whether 630 mg or 840 mg does better than 420 mg, so we don't know the upper limit of its effectiveness. Most studies were with 210 mg a day; I personally take 420 mg a day as I think this has greater benefits without greater side effects. That means a very positive benefit to risk ratio.comments powered by Disqus
