No, the Transportation Security Administration (TSA) will not throw away your vitamins, as they are considered a "solid" medication or supplement. You can bring any quantity of solid vitamins (pills, capsules, or tablets) in both your carry-on and checked luggage. They do not need to be in their original packaging, though it is often recommended for easier identification during the screening process. If your vitamins are in liquid, gel, or gummy form, they are technically subject to the "3-1-1" rule (3.4 ounces or 100ml per container) unless they are considered "medically necessary." If you have large containers of liquid vitamins, you should inform the TSA officer before the screening begins; they may perform additional "swabbing" or testing on the bottle, but they will not discard it if it is clearly a health supplement. TSA's primary focus is on identifying potential explosives and safety hazards, not policing your nutritional routine. To ensure a smooth process, many frequent travelers use a "daily pill organizer" which is perfectly acceptable and will not cause any issues at the security checkpoint.
