What is Zinc Carnosine? The All-Purpose Supplement

What is Carnosine?

Carnosine is a natural compound in your skeletal muscles and brain. Daily intake of foods such as meat or fish contains high amounts of carnosine. Carnosine is an ideal antioxidant – it can decrease stress levels in animals by helping with quicker metabolism of the stress hormone, cortisol, and noradrenaline. It is thought to have many biological roles such as anti-oxidant, pH-buffering agent, chelation of divalent zinc ions and may play the role of a neurochemical messenger in the sense of smell.

Muscle Recovery

In athletes, carnosine can be applied to aid in the recovery of tired muscles and increase muscles work potential. Carnosine buffers lactate caused by exercise in skeletal muscle and may help with fatigue.

Neuroprotective

In addition, carnosine may have anti-aging potential and may be neuroprotective in cerebral ischemia (strokes) in animal studies. Researchers found that carnosine may regulate brain glutamate level under low blood flow conditions and may protect against permanent damage in mice.

Carnosine Supplementation

As seen in Alzheimer’s disease mice models, supplementation with carnosine improves the decline of cognition. It is also seen in elderly people. This elderly group took 1g of anserine/carnosine for 3 months and were given memory tests. This group performed significantly better than the group that did not take the supplementation. Carnosine is easily absorbed in the digestive tract, can cross the blood-brain barrier and has high bioavailability. Additionally, carnosine is water-soluble, heat inactive and non-toxic which make it a good nutrient for supplementation.

What is zinc?

Zinc is an essential trace element that is abundant in the brain and is involved in neuronal excitation. Zinc has many vital roles in cell division, protein, and DNA synthesis. More so, it plays an important role in learning and memory. Zinc regulates the excitability of the brain by binding with N-methyl-D-asparate (NMDA)-glutamate, aminobutyric (GABA) receptors in the brain.

Zinc Deficiencies

Children deficient in zinc may have mental and developmental problems causing learning disabilities and dwarfism. In adults, deficiencies may lead to disorders in learning, taste, and smell.

The recommended adult daily zinc dose is 12mg/day in males and 9mg/day in females.

Zinc Supplementation

More studies are showing that zinc balance aka “homeostasis” is involved in many neurodegenerative diseases such as Alzheimer’s disease, vascular dementia and prion diseases. Newer research found that zinc supplementation significantly decreased triglycerides and low-density-lipoprotein (the “bad cholesterol”).

Combining Zinc and Carnosine

Carnosine may help make zinc more available in the brain. Carnosine binds to zinc and regulates zinc concentration in synapses (the area between two nerve cells where signals are passed). Basically, you need carnosine for zinc to work correctly. Therefore, carnosine is necessary to provide zinc homeostasis and provide protection against a myriad of neurodegenerative diseases.

Gastrointestinal Protection

In Japan, zinc + L-carnosine is clinically used to treat stomach ulcers. It has been suggested that this combination is useful in preventing cancer. This combination has been well studied in patients with gastroesophageal reflux disease (GERD) and has been used to treat any GI condition that requires mucosal protection and repair.

This combination has been studied to protect gut mucosal integrity aka prevent “leaky gut”. In mice studies, it stimulated cell movement and growth and reduced small intestine and stomach injury. In humans, scientists found that this combined supplement can prevent “leaky gut” caused by NSAIDs. NSAIDS can damage the GI tract by reducing mucosal prostaglandin levels, blood flow and stimulates immune cells such as neutrophils. Zinc L-carnosine promotes repair of damaged tissue through wound healing effects.

Zinc L-carnosine has anti-inflammatory and mucosal protective effects by reducing inflammatory cytokines and increasing growth factor expression. More so, this supplement was found to have “cytoprotective” which means it is a compound that protects cells from harmful effects.

In addition, zinc + carnosine when given before chemotherapy prevented oral ulceration in cancer patients. Studies found that it has efficacy in repairing damage caused by radiation for oral mucositis, esophagitis and dermatitis.

Zinc Carnosine Supplementation

Supplementation with carnosine and zinc may promote gut integrity and repair and be important in preventing neurodegenerative disorders such as Alzheimer’s dementia and vascular dementia.

How to take Zinc and Carnosine

Adult Dosage: 75mg- Zinc-L-carnosine complex once or twice daily with meals

Side Effects: Nausea, vomiting, diarrhea  may result if taking on an empty stomach

Frequently Asked Questions

Is zinc carnosine safe?

There have been reports that zinc may cause anemia: One case report of a 17-year-old man taking megadoses of zinc (100mg x 3 daily) had developed fatigue and anemia (his red blood cell counts dropped below normal levels). Another case report noted that a 28-year-old man’s seizures worsened after taking zinc. Additionally, zinc nasal sprays may cause loss of sense of smell.

Carnosine, itself, is well tolerated and relatively safe.
