Once the formulation of a cognitive health product geared toward aging is solid, brand holders need to weigh what can be said about it. This gets into the realm of limitations regarding claims, along with the requirement for substantiation. As this discussion applies to products intended to counteract the effects of aging, the limitations fall largely in the dangerous realm of interpretive assessment (and the required substantiation). Aging is a natural process. Some of the results of aging include mental declination. This should not be confused with any aberrative physiologic occurrence; the slowing of mental activity is “normal” cognitive decline.
The challenges lie in crafting claims—as well as the context in which the claims are presented, since this is a vital factor in interpretive regulatory assessment—to present the age group, targeted benefit and intent without crossing the invisible line into areas such as senile dementia or Alzheimer’s disease. Discussion of improvement in cognitive performance is a very safe area on its own. Blending in age is where the invisible line comes into play. This, in turn, leads to the substantiation requirements.
When demonstrating the potential effects of a dietary supplement in improving cognitive performance, certain considerations must be made, regardless of whether designing or reviewing a study. First it is important to know that a healthy population is used. The ideal would be healthy, older individuals—but those are not an easy find (completed studies, not older people). Most importantly, a legitimate, standardized measure must be applied. The evaluation of any study intended to demonstrate cognitive improvement must meet the same scientific rigor as any other determination. The demonstration of the performance must also be less equivocal owing to the inherently subjective nature of the endpoint measurement. Complete and thorough evaluation of the substantiation must be performed against all aspects of formulation using the substantiation. Clear, concise presentation using the appropriate subjects is key.
