AG1 is not a fake product, but many experts argue it is heavily overhyped. It is generally considered a high-quality, safe, but extremely expensive multivitamin/nutrient powder. Most dietitians recommend spending that money on whole vegetables, fruits, and targeted, cheaper supplements instead. But AG1 claims they are NSF Certified for Sport, which is a high standard. They verify that their product does not contain unsafe levels of contaminants or banned substances, and that the label is accurate. And claim people who struggle to eat enough vegetables or manage multiple supplements, AG1 offers a convenient, one-stop shop for vitamins, minerals, and probiotics.
