Proline supplementation stimulates immune system
Proline & vaccination
Vaccines often contain small quantities of aluminium hydroxide. This compound makes vaccines more effective, but also inhibits immune cells. There must be a better way doing things, the Chinese thought - so they went in search of an alternative. They hope they've found this in the form of proline.
The first group of vaccinated mice were given two injections containing a vaccine only [V-O]; the second group were given a vaccine with aluminium hydroxide [V-H]. The third group were given food that had been enriched with the amino acid L-alanine for a month [V-A], and a vaccine without aluminium hydroxide. The fourth group was given food for a month that contained 0.4 percent L-proline, and a vaccine without aluminium hydroxide. The Chinese used L-proline produced by Ajinomoto.
At the end of the month the Chinese injected the lab animals with Pasteurella multocida. Two days later all mice in the Control group were dead.
The researchers were not able to uncover exactly how proline helps the immune system to work better. They did see slightly higher levels of antibodies in the blood of the proline mice than in the blood of the animals in the V-A and V-O groups.
So doing a quick calculation: a mouse eats about 4 g food per day. If the diet consists of 0.4 percent L-proline, that works out at 16 mg proline. The mice weighed 20 g. Per kg bodyweight they therefore ate 800 mg proline.
Converted to humans, that means 80 mg per kg bodyweight. So if you weigh 80 kg you would need about 6 g proline per day to stimulate your immune system.
