The Longevity Code, Cellular LongevityWhat liposomal glutathione is, and how to take it.

What is glutathione?

Glutathione is a tripeptide, a short chain of three amino acids: glutamate, cysteine and glycine. Our guide to the three amino acids that build glutathione covers each one in detail. The cysteine carries a sulfur-containing thiol group, and that sulfur is the reason glutathione takes part in so much of the cell's redox chemistry, the constant exchange of electrons that runs through ordinary metabolism.

Nearly every cell in the body makes its own. Synthesis happens in two enzyme steps, first joining glutamate to cysteine and then adding glycine, a sequence set out in how the body makes glutathione. The molecule is found throughout the body, with some of the highest concentrations in the liver.

It exists in two states. Reduced glutathione, written GSH, is the working form. When two GSH molecules give up electrons they join through a disulfide bond into oxidized glutathione, written GSSG, and an enzyme later converts it back. Cells keep the large majority in the reduced form, which is why the ratio between the two is a widely used measure in redox biology. The GSH and GSSG cycle is worth reading in full.

On a label, this is why you will see the words reduced L-glutathione. Reduced refers to the GSH state. The L refers to the form of the amino acids, the one found in the body, so L-glutathione and glutathione name the same molecule. Both words describe the molecule itself, before anything is said about how it is carried.

What is liposomal glutathione?

A liposome is a microscopic sphere with a wall made of phospholipids arranged in two layers, a bilayer, around a small watery core. The structure was first described by the British biophysicist Alec Bangham and colleagues in the 1960s, and it has been studied in pharmaceutical science ever since as a way of packaging molecules.

The phospholipid most associated with liposomes is phosphatidylcholine, one of the main components of cell membranes. In Codeage formulas the phospholipids come from non-GMO sunflower lecithin, in a system called Codeage Helix liposomal delivery, and in the capsule the glutathione is carried in that phospholipid complex.

Why package glutathione at all? Glutathione is a small peptide, and the digestive tract contains enzymes that break peptides down into their amino acids. The researchers behind the liposomal pilot study in the table below gave this as the reason for their design: packaging the tripeptide with phospholipids is one approach formulators use.

That is a rationale, not a result. The liposome describes how a formula is built. Whether it changes anything for glutathione in a person is a separate question, and the human research on it is limited.

What can the research actually say?

The question people usually ask is whether glutathione taken by mouth reaches the blood at all. For years the standard reference was the 1992 study by Witschi and colleagues, which followed plasma glutathione for a few hours after a single large dose and reported no significant rise. It shaped a long-held view on oral glutathione, from one administration measured over one afternoon.

The studies that followed changed the shape of the question rather than closing it. They measured glutathione across weeks and months instead of hours, in larger groups and in two forms, and their reported results differ with their length, their design and the form used. A four week trial, a six month trial and a four week liposomal pilot are not three answers to one question. They are three different questions.

The limits are as important as the designs. The liposomal pilot enrolled twelve people with no placebo group, and its authors described it as preliminary. None of the four compared a liposomal form with a standard one in the same trial, so the published record does not settle whether liposomal glutathione differs from regular glutathione in a person.

The useful reading is a modest one. Oral glutathione has moved from a settled no toward an open question, and duration is the variable that differs most across these designs. Anything beyond that is more than the record can carry. Research described here was conducted independently and did not involve any specific Codeage product.

How do you take liposomal glutathione?

Start with the label, because it is the manufacturer's own answer and it comes before any general rule. For Codeage Liposomal Glutathione, the direction is one daily serving taken with about eight ounces of water or another beverage. Each bottle holds 30 servings, a month of daily use.

Can you take glutathione on an empty stomach? The label states that it may be taken with or without food, so it can sit at breakfast, at another meal or apart from meals. The four week trial described above gave its capsules fifteen minutes before breakfast and before dinner, but that was a protocol decision made to standardize the study, not a finding that the timing mattered.

Morning or night? Both fit the label, and none of the four studies tested one time of day against another. What the published designs do share is duration: the trials ran for weeks and months, which is the quietest argument for choosing a fixed point in the day you will actually keep.

The label sets the limits. Do not exceed the stated serving. Anyone who is pregnant or nursing, under 18, or managing a known medical condition should speak with a physician first, and anyone taking medication should raise it with a qualified healthcare professional before adding any daily formula.

What is the difference between 500 mg, 1,000 mg and powder?

All three Codeage liposomal glutathione formulas share the same base: reduced L-glutathione held in phospholipids from non-GMO sunflower lecithin. They differ in the amount per serving, the source of the glutathione and the way they are taken.

The 500 mg formula is built around Setria®, a branded reduced L-glutathione produced through a fermentation process, and our article on why the glutathione source belongs on the label explains what that name tells you. Which amount suits a person is a question for a qualified healthcare professional, not for a table.

Where does glutathione sit in The Longevity Code?

Glutathione sits in Cellular Longevity, the third pillar of The Longevity Code, alongside the molecules of cellular metabolism. A pillar is a location within a framework. It describes a category, and it describes nothing about an outcome for any reader.

The house position is the one set out above. The molecule is well described. The liposome is a formulation choice with a clear rationale and a limited body of human comparison. The routine is a matter of following the label and keeping to it.

Nothing on this page is advice to begin, stop or change anything, and nothing on it replaces a conversation with a qualified healthcare professional.
