USANA vitamins are the only ones I take.

Purity—ensures products are free from contaminants including heavy metals, pesticides, and residual solvents
Identity—confirms the ingredient identity to determine efficacy, safety, and quality
Composition—provides critical data on every batch down to weight, thickness, disintegration, and safety
Strength—includes multi-method testing to prove the potency claimed on each product label
Safety—verifies a high-quality product that’s both safe and effective
How to Recycle: The outside carton is fully recyclable. After single-use stick packs are removed, flatten the box, then place it in a recycling bin.
