Frequently Asked Questions

A: All our products are assigned an expiration date, which is based upon extensive stability studies. We guarantee the potency of the product until the last day of the month noted on the package. There is no evidence to indicate that the ingredients in the product would be harmful if consumed beyond the expiration date. You may not, however, be receiving the amount of each vitamin or mineral listed on the label. The potency of the ingredients slowly diminishes over an extended period of time, and the expiration date is determined by the least stable ingredient in the product. We recommend that the product not be used after the expiration date.

A: Centrum Men builds off of the same great formula as Centrum Adults, but is tailored with nutrients specific to help support men’s health. Centrum Men contains higher levels of vitamins C, E, and K as well as calcium, magnesium, selenium, copper, and molybdenum, all key nutrients needed to help support men’s health.*

A: Lutein is a type of plant pigment called carotenoids which give certain vegetables a yellow to reddish hue. This nutrient is found in the retinas of the eyes, where it is responsible for absorbing high-energy blue wavelengths of light that could damage vision. Low levels of lutein are associated with age-related macular degeneration (AMD) and cataract, two eye diseases that lead to vision loss.

A: B vitamins (such as thiamin, riboflavin, niacin, B6, B12, biotin, and pantothenic acid) play an important role in converting proteins, fats, and carbohydrates to energy. For thousands of years, ginseng root has been used in China, Korea, and Japan because of its reported benefit of feelings of vitality and wellbeing.*

A: Omega-3s are important fatty acids necessary for human health and include eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The body can synthesize EPA and DHA, however, in very small amounts and therefore supplementation is helpful to get the proper amounts.

A: There are two forms of vitamin D—vitamin D2 and vitamin D3. While vitamin D2 is a plant-derived form of vitamin D, vitamin D3 is found in animal-sourced foods and can be made in human skin upon exposure to sunlight and is also found in animal-sourced foods. Vitamin D3 can also be consumed through supplements. We choose vitamin D3 for our Centrum and Centrum Silver multivitamin products because it is the more potent form of vitamin D.

A: Panax Ginseng or Ginseng is an anti-inflammatory, antioxidant, brain function stimulant, and endurance performance enhancer. It improves quality of life, physical and intellectual work capacity.
