AminAvast (Amino Acid Supplement): Cat Kidney Disease Glossary

AminAvast (formerly known as RenAvast) is a nutritional supplement containing a proprietary blend of amino acids and peptides. In the Chronic Kidney Disease (CKD) cat, it is marketed as a "cytoprotectant" to support natural kidney function and maintain the health of renal cells.

The "Proprietary Blend" (AB070597) Unlike single-ingredient supplements, AminAvast is a complex mixture.

Composition: It contains a patented combination of amino acids (like L-Aspartic acid, L-Carnosine, L-Glutamic acid, etc.) and a peptide.
The Claim: The manufacturer states that this specific blend helps support the structure of the cells lining the kidney tubules, potentially reducing the rate of cell death (apoptosis) and slowing the breakdown of kidney tissue.
The Evidence: While there are clinical studies supporting its use (showing stable Creatinine levels over time), it is important to note that much of the research is manufacturer-sponsored. It does not yet have the same level of independent, large-scale peer-reviewed evidence as drugs like Telmisartan or diets like Renal Prescription Food.

Mechanism: "Building Blocks"

Cellular Support: The theory is that by providing specific amino acids that may be depleted in CKD or required for cellular repair, the kidney cells become more resilient to the toxic environment they are functioning in.
Coat & Condition: An often-reported anecdotal benefit is an improvement in the cat's coat quality (silkier fur) and general weight maintenance, likely due to the amino acid supplementation supporting protein synthesis.

Administration

Sprinkle Capsules: It comes in capsules that are meant to be opened and sprinkled onto wet food.
Palatability: Most owners report it is highly palatable and easily accepted by cats, which is a significant advantage over bitter drugs.
Dosing: It is typically dosed twice daily based on the cat's weight.

Safety Profile

High Safety Margin: Because it is composed of amino acids (natural components of protein), it is considered very safe with no known significant side effects or drug interactions reported by the manufacturer.
Potassium Note: It does not contain potassium or phosphorus, so it generally does not interfere with electrolyte management.

Supplements are not regulated by the FDA to the same standards as pharmaceuticals; "natural" does not mean "safe," and ingredients or potency can vary between batches. Always consult with your primary care veterinarian or a veterinary internal medicine specialist regarding your cat’s specific condition and potential interactions with prescribed medications.
