Wound heals faster by supplementing with arginine, vitamin C and zinc

Wounds heal faster by supplementing with significant doses of L-arginine, vitamin C and zinc. This is shown by a small human Australian study, in which patients with pressure ulcers were used as test subjects.

Study
Australian researchers at Deakin University did an experiment with 16 patients who had been staying in bed for so long that they developed pressure ulcers. The subjects were treated in the standard way for this, but the researchers wanted to know whether supplements could speed up the healing process.

The researchers divided their subjects into 3 groups.

Subjects in a first control group received no supplements.

Subjects in a second control group drank a commercially available protein drink twice a day. As a result, the subjects received an additional 18 grams of protein, 72 milligrams of vitamin C and 7.5 milligrams of zinc every day on top of their regular diet.

The subjects in the experimental group drank, just like the subjects in the second control group, a commercial protein-rich product twice a day in addition to their regular diet. As a result, the subjects consumed 21 grams of protein, 9 grams of L-arginine, 500 milligrams of vitamin C and 30 milligrams of zinc every day, in addition to what their regular diet provided.

The supplement the researchers used was Resources Arginaid Extra from Nestle. The researchers were not sponsored by the way.

Results
Over a period of 3 weeks, the researchers assessed the severity of their test subjects' bedsores. They scored the wounds on a scale of 0-17.

The figure below shows that supplementation with arginine, vitamin C and zinc significantly accelerated wound healing.

The researchers also monitored the subjects' body composition and blood. They saw no notable changes.

Conclusion
"The added cost of nutritional support for patients with pressure ulcers represents only a small component of their management care plan", the Australians write.

"The possibility of enhanced pressure ulcer healing using defined amounts of additional arginine, vitamin C and zinc could significantly reduce the costs associated with the management of pressure ulcers as well as decrease patient pain and discomfort."
