Why do some products (including supplements) have a distinct scent?
Many manufacturers add synthetic masking agents to their products in an attempt to hide the natural scent and/or taste of certain raw materials. USANA does not add fillers to its products, so some supplements may possess a noticeable scent upon opening. This is not generally a cause for concern.
The USANA supplements with particularly strong scents have natural ingredients added to offset the effect. For example, BiOmega contains a small amount of lemon oil to offset the fishy aftertaste associated with high-potency fish oil supplements.
Because most USANA supplements contain naturally derived ingredients, the scent of certain products may vary slightly from batch to batch. Natural variations in scent and appearance are not generally a cause for concern.
