Lys-Pro-Val tripeptide related to alpha-MSH
KPV is the tripeptide lysine-proline-valine, corresponding to the C-terminal sequence of alpha-melanocyte-stimulating hormone. It is studied in experimental inflammatory biology.

Human cathelicidin antimicrobial peptide
LL-37 is a human cathelicidin peptide involved in innate immune biology. Its naturally occurring role does not establish the safety or efficacy of administering LL-37 as a drug.

Polyunsaturated fatty-acid family
Omega-3 is a family, not a single molecule. ALA, EPA and DHA have different roles; food, supplement mixtures and prescription formulations are not interchangeable.

Prescription mTOR inhibitor / investigational aging research
Rapamycin, also called sirolimus, is an immunosuppressant with approved disease-specific uses. Animal lifespan findings are not proof of safe or effective human anti-aging treatment.

Essential mineral / selenoprotein nutrient
Selenium contributes to selenoproteins involved in thyroid hormone metabolism and cellular protection. Its biological role does not establish that supplements prevent cancer.

Thymosin alpha-1 (thymalfasin), a 28-amino-acid peptide
Thymosin alpha-1, also called thymalfasin, is a 28-amino-acid peptide studied in immune regulation. Clinical findings vary by disease and are not evidence of a universal immune benefit.

Botanical / curcuminoid-containing ingredient
Turmeric contains curcuminoids studied for inflammatory and symptom outcomes. Laboratory effects do not establish broad disease treatment, and enhanced-absorption products have important safety concerns.

Vitamin / water-soluble nutrient
Vitamin C supports collagen formation and helps the body absorb nonheme iron. Preventing deficiency does not mean extra vitamin C prevents cancer or cardiovascular disease.

Fat-soluble vitamin / hormone precursor
Vitamin D helps regulate calcium absorption and bone mineralization. Correcting deficiency is not the same as preventing cancer or heart disease in otherwise healthy adults.

Essential mineral / enzyme cofactor
Zinc supports enzymes, cell division and normal immune function. Correcting deficiency is different from claiming a zinc product prevents infections.
