Lipids for cell membranes help with longevity

Phosphatidylcholine (also called Polyenylphosphatidylcholine) is a major phospholipid, very involved in the synthesis of the membranes of our cells. It is produced by the liver naturally, helps with digestion, helps maintain skin elasticity and is essential to brain function. Is it also involved in aging? A thousand times yes, because, in young subjects, it is present in greater quantities than in the elderly[1].

Long Long Life does not sell any of these products. We believe this to be the price of freedom.

Since we have no financial interest in this, we can tell you the whole truth on the treatments being developped to fight against aging, and give you the best information possible.

Phosphatidylcholine and brain health

Phosphatidylcholine helps maintain the integrity of these membranes and is essential for the body to work. Naturally produced by the liver, it is also used in the composition of bile (digestion of fat). When metabolized by our body, it can release a choline molecule that can be used by the brain to produce acetylcholine[2]. Therefore, phosphatidylcholine supplementation can improve brain function by boosting acetylcholine synthesis[3]. This has led to pre-clinical and clinical studies, particularly on Parkinson’s disease, with the hope of finding new therapeutic approaches, but the results have proved contradictory[4, 5]. However, in the treatment of bipolar disorders, phosphatidylcholine supplementation appears to be beneficial[6]. New studies have also looked at Alzheimer’s disease and show that there is an imbalance in phosphatidylcholine metabolism that can promote the disease[7].

Aging and other diseases

The main role of phosphatidylcholine in cardiovascular diseases appears to be the prevention of hypercholesterolemia[8]. Indeed, in case of mild hypercholesterolemia or in prevention, phosphatidylcholine supplementation allows a decrease in circulating cholesterol. However, these results should be viewed in retrospect as the latest studies are relatively old and little new research has been done on the issue. Phosphatidylcholine derivatives can also have an interesting effect, as is the case of DLPC, whose role is still under investigation but which seems to allow the reduction of glucose and blood triglycerides, thus promulgating an anti-diabetic effect[9].

All these combined actions of phosphatidylcholine go in the direction of a reduction of the risks of development of age-related pathologies. It seems to act directly by maintaining brain function, in addition to its beneficial effects on the cardiovascular system.

  • Availability: over-the-counter
  • Route: oral
  • Dosage: between 1 and 4 g / day

No counter-indications are known to date. In very high doses, it is possible to have some digestive issues.

It is important to differentiate between lecithins, phospholipid mixtures containing phosphatidylcholine and pure supplements. The word lecithin is, in biochemistry, synonymous with phosphatidylcholine, but many abuses of language are found in food supplements (where supplements bearing the name “lecithin” can contain from 25% to 95% phosphatidylcholine). Although lecithins have a beneficial effect on digestive health, their concentration of phosphatidylcholine does not always seem sufficient to obtain an anti-aging effect.
