Dear Friends and Valued Customers,

I'm very pleased to team up with Dr. Derrick DeSilva on yet another breakthrough supplement. You may have heard about liposomal vitamin C or even tried some of the incredibly expensive products on the market. But this is a real case of "buyer beware." Here Dr. DeSilva explains the difference between a true liposome and other products that simply blend active compounds with phospholipids. Read on, then compare Swanson Ultra® Liposomal Vitamin C to others—with Swanson, you'll not only save, but you're guaranteed true liposomal delivery with every dose. —Lee Swanson

Swanson: Dr. DeSilva, you've been involved with liposomal delivery technology almost since the beginning. What has been your experience with this novel delivery form?

DeSilva: I was lucky enough to be approached by one of the pioneering companies in liposomal technology about 15 years ago. At the time, the technology had been successfully developed and utilized in pharmaceuticals, and this company was looking to adapt it for broader application. It was exciting, but it was also expensive. Today, I'm even more excited about liposomal delivery than I was back then, because it's now affordable enough that it can be applied to a wide variety of nutrients and active ingredients while keeping prices within reach for average consumers.

Swanson: You caution people to do their homework and make sure that they're getting true liposomes. But before we get into that, tell us: what is a liposome?

DeSilva: Liposomes are tiny microscopic "bubbles" or spheres formed by phospholipids that act as carriers to deliver active agents—in this case, nutrients—right to our cells and tissues. They're effective because their makeup is similar to that of our own cells. The exterior lining of our cells contain phospholipids just like those that form a liposome. Because of this, liposomes (and the nutrients they carry) are drawn to our cells in ways other delivery forms are not.

As technologically advanced as modern liposomes are, the fact is that they are merely an attempt at mimicking what Mother Nature has already perfected. The first time we encounter liposomal nutrient delivery is right after birth, in the form of mother's milk.

Swanson: That is truly interesting. I did not realize mother's milk actually contains liposomes. So what distinguishes a "true liposome?

DeSilva: This is where it gets tricky and technical. To form a true liposome, you must react the active ingredient with the phospholipid carrier in such a way as to create tiny uniform spheres that completely envelop and hold the active component at a particle size of about 150 nanometers. You can't simply mix vitamin C with lecithin and call it a liposomal product, yet that is what some products turn out to be when analyzed.

So the particle size matters, and the materials themselves matter, as well. The phospholipid should not be hydroxylated or hydrogenated, and it should be as pure as possible. My Liposomal Vitamin C uses all-natural phosphatidylcholine from non-GMO sunflower lecithin. This is preferred because phosphatidylcholine is one of the primary phospholipids in all cell membranes.

When produced correctly, you can see highly structured spherical liposomes under a microscope, as in the photo shown. Products that are not made properly and do not contain true phytosomes will appear as unstructured oily smears without any distinguishable structure.

The image here is a real shot of our liposomes as seen through a scanning electron micrograph, and it's just one way we can confirm that we've got the real thing. Another way to confirm a true liposome is to use what is called "dynamic light scattering" to measure the particle size. As you can see from the chart, 95% of the liposomes in our product are between 50 and 420 nanometers, with the vast majority falling within that 150 nm target range.

Swanson: You mentioned that liposomes are better able to deliver nutrients to our cells tissues. Is that the primary advantage of liposomal delivery? How do we know it's any better than other forms?

DeSilva: Better absorption, higher bioavailability, improved utilization—these are the primary benefits liposomes have over other forms of dietary supplements; but there's more to consider than just these three things. In the case of vitamin C specifically, the liposomal form is better tolerated, making high-dose supplementation easier and more effective. Vitamin C is highly acidic and can cause digestive upset, diarrhea and other unpleasant side effects when taken in high amounts. With Swanson Ultra Liposomal Vitamin C, the phospholipids serve as a barrier to the ascorbic acid through the digestive tract, virtually eliminating the concern of GI distress.

Swanson: Thank you, Dr. DeSilva, for bringing us yet another breakthrough supplement
