English to French Science Nutrition

My main problem is with the phrase "point-of-use". I came across it in expressions such as , "point-of-use fortificant", "point-of-use supplement", "point-of-use product".
Below is a sentence with "point-of-use product".
Many thanks
We intend to improve the nutrient content of traditional baby foods and the quality of local diet by introducing point-of-use products, including micronutrient powders such as lipid-based nutrient supplements or Sprinkles.
