TLDR:

  • If you have upper gut (stomach and esophagus) discomfort (ulcers, H. pylori dysbiosis, reflux, or gastritis and can only afford one supplement, I recommend zinc carnosine. It is one of the best supplements for upper gut issues.
  • Zinc is a trace mineral that can decrease wound healing time, is essential for maintaining the integrity of the immune system, and much more.
  • Your body uses zinc for testosterone production.
  • Carnosine is both an amino acid and an antioxidant.
  • Carnosine protects our cells, especially our mitochondria, from oxidative stress and advanced glycation end product damage (diabetic neuropathy).
  • Rarely, high doses of zinc carnosine over a long period may cause zinc toxicity and lowered immune system functioning.
  • My top two recommended brands of zinc carnosine are Peptic-Care ZC and Doctor’s Best PepZin GI.

Quite a few people ask me if they could only afford one supplement to help with upper gut discomfort (ulcers,1 H. pylori infection,2 or gastritis,3 reflux), what supplement would I suggest they use for their troubles? If I had to choose one digestive supplement that could handle those multiple upper gut issues and more, it would be zinc carnosine. It is one of the best supplements for upper gut issues. Zinc carnosine is the chelation of the mineral zinc and the amino acid carnosine.4

 

Zinc

 

Zinc is an essential trace mineral that can decrease wound healing time5 and is essential for maintaining the integrity of the immune system.6 The immune system uses zinc to help develop and maintain the function of neutrophils, macrophages, killer cells, and B / T cells.7 Zinc is also a crucial component in the production of the antioxidant enzyme CuZnSOD. 8 Copper and zinc combine with the superoxide dismutase enzyme to produce CuZnSOD. CuZnSOD is a chelated enzyme that has both potent antioxidant and anti-inflammatory abilities.9 Zinc in studies has also been known to shorten the duration of diarrheal conditions (mainly bacterial infections). The mechanism of action of zinc in shortening diarrhea conditions is that the mineral enhances immune system functionality, reduces dysbiotic flora, relieves gastrointestinal inflammation, and binds with microbial toxins, helping the body eliminate them through the stool.10

Finally, zinc is used in the body to produce testosterone (limits the amount of DHEA in males that becomes estrogen),11 growth hormones, and insulin-like growth factor-1.12 Proper zinc intake is very important for males. If you are male and do not have upper gut issues, I recommend taking fifteen miligrams of Now L-Optizinc daily for proper testosterone production.

 

Different Forms of Zinc

 

Recommended Forms of Zinc

Zinc L-monomethionine

Zinc L-monomethionine is the form of zinc that I recommend the most (yes, even more than zinc glycinate). Zinc L-monomethionine is a highly absorbed form of zinc with multiple benefits. Zinc L-monomethionine is highly absorbed because it is bound with the L isomer of methionine. Methionine is an essential amino acid, which means your body cannot produce this amino acid, and it must be supplemented through the diet. Methionine has two isomers (an isomer is a molecule with the same molecular formula, but different chemical structures), D and L. The D isomer is synthetic and is created during supplement production. The L isomer is natural and is what the body recognizes as methionine. Therefore, the L isomer has a higher absorption. The extra methionine provided by the zinc supplement is used in the body to make cysteine, carnitine, taurine, lecithin, SAM-e, and phosphatidylcholine.

Methionine, when converted into SAM-e, eventually degrades into a byproduct known as homocysteine (excess homocysteine has been linked to being a possible factor in developing heart disease). Homocysteine is then immediately inactivated and turned into either the amino acid cysteine or methionine in the body before any damage can be done, as long as adequate B12 and glycine are provided. Methionine benefits the body in supplemental form as long as you take a good B vitamin complex or a supplement containing the amino acid glycine.

Zinc Glycinate

Zinc glycinate is a zinc supplement chelated with the amino acid glycine. Glycine reduces anxiety in the body and promotes a feeling of well-being. Check your supplement to see if your glycinate chelate is made from the TRAACS Albion process of manufacturing chelates (the supplement should have the TRAACS or Albion logo). Choose a glycinate product that uses TRAACS to get the best quality.

Zinc Monomethionine

Zinc monomethionine is the brother of Zinc L-methionine and also has excellent absorption. However, zinc monomethionine is not absorbed well by our small intestine or L-methionine because it contains both the D and L isomers. When using this supplement, a B vitamin complex supplement or glycine supplement may also be needed to help with absorption and monomethionine regulation. 

Zinc Picolinate

Zinc picolinate is a zinc supplement that is chelated with picolinic acid. Picolinic acid is a compound that is an isomer of niacin and is a carbolite of the amino acid tryptophan. Zinc picolinate has superior absorption, and picolinate absorption is superior to even gluconate chelates.

ZMK

An excellent form of zinc supplementation also includes magnesium chelates from the Krebs cycle: citrate, fumarate, malate, succinate, and alpha-keto-glutarate. ZMK is excellent for athletes and is very good for recovery. A ZMK supplement should be taken before bed.

Zinc Gluconate

A form of zinc chelated with gluconic acid occurs from the natural fermentation of glucose. Zinc gluconate has above-average absorption in the body. It is the type of zinc found in products like throat lozenges and nasal sprays used to shorten the duration of the common cold. Zinc gluconate nasal sprays have been linked to permanent loss of the sense of smell in some people and should be avoided.

Zinc Orotate

Like magnesium orotate, zinc orotate is one of the least known forms of supplemental zinc. The extra orotate will help with muscle regeneration and repair. Women should avoid it if they are or are trying to become pregnant since it may be mutagenic (it is only found as a possibility in rats in vivo, and rats are biologically different from humans, so it might be safe after all).

Garbage Zinc Chelations

Zinc Citrate

Zinc citrate is zinc chelated with citric acid. Zinc citrate has an average absorption rate and can increase stomach acid levels. An animal study showed that the citric acid in the zinc citrate supplement can offset some of the absorption problems if the zinc supplement is taken with a meal high in phytic acid. Citrate may interfere with ceruloplasmin production.

Zinc Oxide

Zinc oxide has a poor absorption rate in the human body, which is why it is used as a sunscreen and a skin protectant. I only recommend using zinc oxide skin care products, but limit the products made with nano zinc oxide, which can be absorbed. Nano zinc oxide safety has not yet been thoroughly studied.

Zinc Aspartate

The average absorption of zinc aspartate is not worth the extra aspartic acid. Too much aspartic acid may be neurotoxic. This recommendation includes ZMA supplements.

Zinc Pyrithione

Zinc pyrithione is mainly used in anti-dandruff shampoos. Its mechanism of action for eliminating yeast is to disrupt the yeast’s membrane transport by blocking the proton pump that energizes the transport chain. However, zinc pyrithione can cause irritation and allergies, so its use should be limited.

 

Carnosine

 

Carnosine is both an amino acid and an antioxidant. Most carnosine in the diet comes from the ingestion of red meat. Carnosine protects our cells, including our mitochondria, from oxidative stress and advanced glycation end products (AGEs). 13 AGEs are produced during the breakdown of glucose, fructose, and galactose by the body for assimilation. Excess AGEs produced in the body have been linked to various diseases, including diabetes 14 cardiovascular disease,15 to Alzheimer’s disease16 as well. Sadly, the amount of carnosine in most zinc carnosine supplements is tiny and is broken down easily by the enzyme carnosinase, so the effects of the supplemental carnosine would be minimal.17

 

Zinc Carnosine

 

Zinc binds quickly to stomach tissue if taken on an empty stomach. If you take a zinc supplement on an empty stomach, it causes severe stomach pain and gastritis. It has been theorized that zinc ions are highly soluble in stomach acid and have corrosive, antimicrobial, and immune-stimulating properties that irritate the stomach tissue because of the direct absorption of the zinc ions. If you chelate zinc with carnosine, the chelation slows down the absorption and elimination of zinc from the stomach. Zinc can then repair the stomach and intestinal tissue directly without irritating it. Zinc carnosine supplementation has been shown in studies to effectively tackle increased gut permeability (leaky gut) and reflux. Zinc carnosine may be taken on an empty stomach as needed. Zinc carnosine also protects the stomach lining from opportunistic H. pylori dysbiosis and NSAID-induced stomach inflammation that causes ulcers from long-term medication use.18

 

Supplemental Recommendations and Toxicity

 

Dietary zinc can easily be obtained by eating wild-caught seafood (mainly crab and oysters), pastured meat, pastured animal dairy, organic cashews, organic chickpeas, organic almonds, organic peanuts, organic pumpkin seeds, and organic beans. Supplementation might be needed in people who have followed a vegan or vegetarian diet improperly for a long time or in people who have used medications, including ACE inhibitors for blood pressure, that cause a zinc deficiency. Elevated doses of zinc over a long period can cause toxicity and hinder your immune system. Symptoms of zinc toxicity include nausea, vomiting, abdominal pain, frequent colds, increased cholesterol levels, and chills19 If I had to take a maximum dose of zinc carnosine I would take no more than four hundred and fifty milligrams of zinc carnosine (one hundred milligrams of elemental zinc) daily total for two weeks. Most supplement instructions recommend taking zinc carnosine twice daily for seventy-five milligrams of zinc carnosine daily (fifteen milligrams of elemental zinc).

If you supplement zinc, I recommend no more than sixty milligrams of elemental zinc daily. If you supplement with more than sixty milligrams of zinc, I suggest that, as long as you do not suffer from adrenal fatigue and your ceruloplasmin levels are normal, you should frequently ingest high-copper organic foods like pastured animal liver, organic dark chocolate, organic avocados, and organic nuts.

Excessive copper buildup and toxicity can worsen adrenal fatigue symptoms, so limit copper intake during zinc supplementation until adrenals have healed. Zinc carnosine is one of my top three favorite digestive health supplements; everyone should keep a bottle in their medicine cabinet so they can take it when needed.
