NADES (Natural Deep Eutectic Solvents) as a concept of "In-situ synthesis".

Abstract The situation in modern pharmacology and nutrition is paradoxical: often a branded "salt" (sulfate or hydrochloride) is valued higher than a pure substance in a bioactive environment, simply due to marketing inertia. From the point of view of biochemistry in 2026, NADES (natural eutectics) is the cutting edge of science, which should become a mass standard. We have actually implemented the concept of "In-situ synthesis" – when the bioactive substance is obtained in the closest possible to natural form and immediately stabilizes in the transport environment.
