Can a multivitamin replace vegetables?
No. A multivitamin can help cover some vitamin and mineral gaps, but it does not provide the same food volume, fiber, water, phytochemical mix, chewing, or meal structure that produce provides.
That does not mean multivitamins are useless. They can be reasonable insurance during a low-calorie phase, travel, appetite disruption, or a temporary period of limited food variety. But the target is still a diet that includes enough whole foods to support fullness, digestion, and health.
