The capsules smell funny, is this safe and normal?
Most supplement ingredients have distinct smells (and flavors). This is often due to certain compounds contained within the ingredients themselves, such as sulfur (a crucial component of many compounds). The products are perfectly safe and effective.
Why do some of my capsules have an uneven fill volume? Does this mean they aren’t dosed properly?
During the production process, various excipients are utilized to ensure the proper amount of active ingredients flows into each capsule.
Due to the varied materials and densities of these excipients (as well as the active ingredients), capsules are filled by weight and not by volume. This is basically the same way you’d find food in boxes and bags at the grocery store that is “Filled by weight not by volume, some settling may occur”.
Unlike the food industry, the supplement industry has a more tightly regulated fill tolerance. Our manufacturers have an internal fill tolerance of + - 5%, and capsules are weighed to make sure they consistently fall in that range to meet specifications.
Basically, some capsules have the powders packed down, others have it loosely filled, but overall they meet the industry leading specifications for dosing tolerance.
