Zinc supplements with the fewest additives

Zinc supplements may assist the immune system, fight acne, and more. However, many zinc supplement brands contain more than just zinc. For example, silica or silicon dioxide are often added to prevent caking, magnesium stearate or stearic acid for easier manufacturing, hypromellose (hydroxypropyl methylcellulose) as an emulsifier or thickener, and povidone as a binder.

I try to avoid these additives because they may have questionable health effects. If you want to do the same, my recommendations for the purest zinc supplements are:

Recommended as purest zinc capsules:

All ingredients:

Zinc orotate, rice bran extract, hypromellose (vegetable capsule).

Recommended as purest zinc lozenges:

Cold-EEZE wouldn't tell me the exact formulations of their natural flavors, but said that the flavors come from cherry, honey, strawberry, lemons, mint, or fruits, depending on which flavor you choose.

Recommended as purest powdered zinc:
