If you’re not eating enough vegetables, the most practical options are greens powders/“vegetable” powders and a basic multivitamin/mineral. They can help fill some nutrient gaps, but they are not a replacement for whole vegetables, especially because whole veggies provide more fiber and the full food matrix of nutrients. [1][3][5] Greens powders: These are the closest match to what you’re asking for. They typically contain blends like wheatgrass, barley grass, spirulina, chlorella, and vegetable extracts, and are marketed to help cover shortfalls in vitamins, minerals, antioxidants, and phytonutrients. [1][2] Multivitamin/mineral (MVM): This is often the most evidence-backed “gap filler” for general nutrient shortfalls. Research reviews and CRN state that MVMs can help reduce inadequacy for nutrients such as vitamins C, D, B6, B12, and folate, though they usually do not provide much potassium or calcium. [4][5] Targeted single nutrients: If your diet is low in vegetables, the nutrients most commonly missed include fiber, potassium, calcium, and vitamin D; some of these are hard to fix with a standard multivitamin alone, so a targeted supplement may be more useful depending on your diet and labs. [5] A few consumer-friendly brand examples mentioned in the results are Opti-Greens 50 (greens powder), AG1, and Laird Superfood Prebiotic Daily Greens. These are presented as convenient greens supplements, but the results do not establish that they’re superior to simpler, less expensive options for most people. [1][2] What to look for on the label: No huge megadoses of vitamins A, E, or other fat-soluble nutrients unless a clinician recommended them, because excessive intake can be harmful. [3] Meaningful vitamin/mineral coverage if you want a general gap filler. [4][5] Fiber if your diet is low in vegetables, though most powders still won’t match real produce. [1][5] What supplements can not do well: Replace the fiber and fullness you get from whole vegetables. [1][5] Reliably supply enough potassium and often calcium in a standard multivitamin. [5] Fully substitute for eating vegetables long-term. [1][3] If you want the simplest practical approach, I’d suggest: A basic multivitamin/mineral if you want broad coverage. [4][5] A greens powder if you specifically want a vegetable-like add-on and don’t mind paying more for convenience. [1][2] If you tell me your age, sex, diet pattern, and whether you want budget, best-tasting, or most evidence-based, I can narrow this to a few specific product types.
