Liposomal Vitamin C: What You Need to Know
What is Liposomal Vitamin C?
Liposomal vitamin C is a specialized form of vitamin C designed for improved absorption and utilization by the body. It consists of tiny spherical cells called liposomes, which have an outer layer made of fatty acids called phospholipids sourced from sunflower or soy. These liposomes encase the water-soluble vitamin C within an inner compartment, offering protection and enhanced bioavailability.
The Advantages of Liposomal Vitamin C
One of the primary advantages of liposomal vitamin C is its superior absorption. Our intestinal cells have a threshold for absorbing vitamin C, which can lead to digestive issues like excessive gas or diarrhea when high dosages are taken. Liposomal vitamin C is absorbed almost twice as effectively as regular vitamin C, making it a popular alternative to intravenous (IV) administration.
Health Benefits of Liposomal Vitamin C
The health benefits of liposomal vitamin C align with those of regular vitamin C. Vitamin C is essential for collagen production, which is crucial for healthy connective tissues, wound healing, gum health, and preventing easy bruising. It also plays a vital role in antioxidant defense, immune function, brain chemical and hormone synthesis, as well as the absorption and utilization of other nutrients.
Scientific studies on liposomal vitamin C have shown promising results. For example, liposomal vitamin C has been found to prevent reperfusion injury, a type of tissue damage that occurs when blood supply returns after a period of oxygen deprivation. Reperfusion injury is a concern in heart and cardiovascular procedures, as well as after heart attacks or strokes. While intravenous vitamin C is commonly used for this purpose, oral liposomal vitamin C can provide similar protection due to its high absorption rate.
Liposomal vitamin C is also used to support cancer patients undergoing high-dose IV vitamin C therapy, as it offers an alternative with increased bioavailability. Additionally, it has been studied for its potential in reducing the severity and duration of the common cold, particularly in individuals facing high-stress situations.
Sunflower-Derived Phospholipids
Phosphatidylcholine (PC) derived from sunflower lecithin is considered the ideal carrier for liposomal vitamin C. PC helps maintain the integrity of liposomes and enhances their effectiveness. Sunflower lecithin is often preferred over soy lecithin due to its non-GMO nature and greater stability in liposomal formulations. If soy lecithin is used, it should be sourced from non-GMO varieties.
Liposomal Quality and Homemade Products
To ensure efficacy, liposomal products must be manufactured properly. The liposomes should fall within the optimal size range of 100 to 400 nanometers and undergo quality testing at FDA-regulated facilities.
It is important to note that homemade liposomal mixtures made by blending vitamin C powder, vodka, lecithin, and water in a blender may not produce liposomes of the necessary quality to effectively carry vitamin C.
Dosage, Safety, and Side Effects
The recommended daily intake (RDI) for vitamin C is 90 mg for adult men and 75 mg for adult women, with an upper limit of 2,000 mg per day. Liposomal vitamin C, with its enhanced absorption, can be used daily or for specific indications. Generally, liposomal vitamin C is well-tolerated and does not typically cause gas, bloating, or diarrhea, even at higher dosages. However, dosages exceeding 2,000 mg may pose an increased risk of kidney stones, as with regular vitamin C.
Note: It is always advisable to consult with a healthcare professional before starting any new supplement regimen or exceeding recommended dosages.
