A supplement blend has several ingredient roles

AG1 describes its formula as vitamins, minerals, probiotics and other ingredients. The inspected US overview lists 40 calories and 2 g of protein per serving. Check your regional package for the complete ingredients and amounts: a formula described on another country’s website may differ. [1]

Ingredient count is not nutritional completeness

A long list of micronutrients does not provide the energy, protein and variety of a meal. Treating this drink as breakfast by itself would leave a different nutritional gap than using it alongside food. NIH guidance also distinguishes supplements from the range of nutrients and other components supplied by a varied diet. [1][2]

Check the overlap before adding it

Imagine already using a multivitamin and then adding AG1. Compare the actual amounts on both labels rather than counting them as unrelated products. Review botanical ingredients, medicines and any clinician-directed restrictions together; this ingredient overview does not establish that every person needs the blend. [2][3]
