Dr. Derrick DeSilva's Liposomal Vitamin C from Swanson Ultra is a state-of-the-art formulation that packs vitamin C into fat-soluble liposomes. These liposomes deliver the vitamin safely through the digestive system directly to the bloodstream for optimal bioavailability. It’s gentler on the digestive tract than conventional ascorbic acid, making it ideal for supplementing at higher intake levels.

What is a liposome?
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.

What distinguishes a “true liposome?”
To form a true liposome, you must react the active ingredients with the phospholipid carrier in such a way as to create tiny uniform spheres that complete envelope 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.

The particle size matters, the production method matters, and the materials themselves matter. The phospholipid should not be hydroxylated or hydrogenated, and it should be as pure as possible. 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.

How do we know that liposomal delivery is better than other forms for delivering nutrients to our cells and tissues?
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 Liposomal Vitamin C, the phospholipids serve as a barrier to the ascorbic acid through the digestive tract, virtually eliminating the concern of GI distress.

Summary of Customer Ratings & Reviews

Customer Ratings & Reviews

Rated 3.2 out of 5 by 13 reviewers.
Rated 2 out of 5 by No Effect that I could tell My doctor told me to switch to a liposomal C, and I bought several bottles of this product. I think it tastes awful, and I did not notice that it had any beneficial effect, even after several months of use. July 4, 2016
Rated 5 out of 5 by Good product It works well, but you have to make sure it will not get stuck in the stomach for the acid there will destroy the liposome structure. So as many the liposomes must bypass the stomach and be flushed directly in the small intestines to fool the digestive system. The best is, to dilute it with a lot of water and never mind how it tastes., so as many liposomes encapsulating the C Vitamin will go through the small intestines directly into the the blood. March 29, 2016
Rated 1 out of 5 by Disappointing Compared to other brands of Liposomal vitamin C's out there, this formula is a major disappointment. It's simply not effective, with no discernible difference, even when taking frequent doses. I'd stick to more reliable brands such as Lypo-Spheric (also sold by Swanson's). January 3, 2016
Rated 2 out of 5 by Be sure to check the date of manufature. I received my last bottle on 10/30/15. The manufacture date was 12/14. Which means it has been in the warehouse for nearly a year. Liposomal vitamin C is quite perishable and because of this some companies package it in individual foil packets. Heat destroys the great benefits of liposomal vitamin C. In the summer months it should only be shipped in cooled insulated packages or not at all. I will be ordering this from another source in the future. October 30, 2015
Rated 5 out of 5 by Great stuff This is an awesome deal on the best form of Vitamin C you can get! Thank you Swanson Vitamins for another great product!! March 29, 2015
Rated 2 out of 5 by Not the best liposomal C Ordered this twice. Won't order again. Not very effective compared to other liposomal Cs on the market. January 21, 2015
Rated 4 out of 5 by Interesting Vit. C I have been trying this product for about 3 weeks. I believe that I am already noticing some benefits, but it probably is to early to really tell. January 12, 2015
Rated 3 out of 5 by Jury still out Not very sure about this supplement. Subjectively, it doesn't make me feel any better than the vitamin C tablet I have been taking regularly. Yet it costs a whole lot more, and requires me to shake up the bottle, measure the portion, and mix it with water. On top of that, I think it may be responsible for the heartburn I have been experiencing the last few weeks. Highly unlikely that I will re-order this one. December 18, 2014
Rated 1 out of 5 by Liposomal Vit. C Have not noticed any difference at all, do far. December 6, 2014
Rated 2 out of 5 by I don't think it works First the pro: It tastes great! I would put it in a little bit of water and drink it. I just love the the taste of it! Cons: I don't think it works. From what I have read about making your own Liposomal Vitamin C is that people stated that they immediately could feel it. I couldn't feel anything different with this product. The first time, I took 1 teaspoon. The next day I took a 1 tablespoon. The third and subsequent days I took 2 tablespoons and still didn't feel anything different. It is possible that this is a legitimate product, I just personally didn't notice any effect. December 6, 2014
Rated 5 out of 5 by Great Product! It really seems to boost my immune system and it tastes great, too! November 22, 2014
Rated 5 out of 5 by Easy to take I am so happy to find an easy to take Liposomal Vit C which I has been recommended to me by my naturopath. Not only is it more convenient than packages, it does not contain alcohol and tastes ok. Also it is less expensive. November 18, 2014
