A powder composition for nutritional supplements that prevents protein denaturation and coagulation when reconstituted in acidic or protein-containing liquids. The powder contains a phosphate buffer, amino acids (glycine, N-acetyl cysteine, and L-cysteine), vitamins (E, C, and B2), and minerals (zinc), with less than 1% protein content. The amino acids are present in free, dipeptide, or tripeptide forms, and the powder is substantially free of enzymes and antibodies.
