Nutritional supplements and most medications are meant to target specific physical systems or organs. Intravenous drip and injection are the most effective methods of delivery, transferring necessary chemicals directly to the blood. When swallowed, medications usually face degradation in the acids of the upper digestive tract. Liposomal encapsulation creates a protective barrier, ultimately allowing more complete absorption.

Scientists first became aware of the process during the 1960s, and their discovery ultimately led to new and more effective means of administering drugs internally. Today, it is widely used in the treatment of age-related degenerative conditions affecting vision, stubborn fungal infections, and even some kinds of cancer. Although standard methods of delivery still predominate medically, encapsulation has proven to be a viable alternative.

For a medication to pass through the upper digestive tract without being dissolved, it must be protected by a safe and non-toxic barrier. The substance used to encapsulate these drugs is an organic material that closely mimics human cellular walls, making it safer to ingest. After it has been activated by using one of three common processes, small bubbles of liposomes are formed around the tiny grains of medication.

These individual capsules can be ingested together in a medium, and are shielded from damage until they can be absorbed into the bloodstream via the small intestine. In many cases this process improves the overall therapeutic goal, with the added benefit of fewer side effects. While a significant improvement, this method of delivery does not accommodate all drugs, and works best with water-soluble medications.

There are fewer unwanted physical reactions, and immediate advantages for patients. Because lipsomes are biodegradable and always physically compatible, they leave no toxic substances behind. Not only can they survive an attack by harsh digestive acids, but later function as tiny time-release agents within the intestine. Many drugs used to fight cancer can create collateral damage, and this form of delivery provides greater control.

While being used successfully today in many hospitals, there are some drawbacks. Production costs are comparatively high, but are subject to a natural decrease as product use expands. Seal leakage has been an issue in some cases, and simple oxidation processes can diminish effectiveness. Certain drugs may experience a diminished half-life, and their long-term viability may be reduced. Even with these known issues, positive benefits exceed negative reports.

The past ten years have witnessed a transition from primarily medical use to include delivery of cosmetic and nutritional substances. There is ample anecdotal evidence touting the additional well-being that may result from delivering common vitamin dosages in this fashion. Many people subscribe to the idea that vitamin C is a natural enemy of upper respiratory infections, and also believe that this type of delivery increases effectiveness.

Although information highlighting consumer ability to create encapsulated vitamins, minerals, and even herbal extracts is readily available, making high-quality formulations can be costly and involved, and will not effectively combat the normal issues associated with aging. As support and development of this process continues in the medical world, the public will benefit most from it being used in conjunction with health regimens that have already been proven effective.
