Antiaging nutraceutical ingredients: What’s currently trending?

The list includes nutraceuticals that can positively impact the aging process itself as well as those that positively impact aspects of human physiology that tend to decline with age, such as joint health and cognitive health.

In 2020, the global antiaging market was estimated to be worth about $58.5 billion and projected to see a compound annual growth rate (CAGR) of 7% between 2021 and 2026.1 Dietary supplements and the nutraceuticals they provide are unquestionably a significant part of those sales.

Defining Antiaging Nutraceuticals

The term antiaging can incorporate a broad range of nutraceutical possibilities. For the purpose of this article, let’s define antiaging nutraceuticals as those ingredients that help to address health and wellness issues associated with aging. In this context, that would potentially include nutraceuticals that can positively impact the aging process itself as well as those that positively impact aspects of human physiology that tend to decline with age, such as joint health and cognitive health. Ahead, we touch on a few promising contenders.

Nutraceuticals for the Aging Process

ResveratrolResveratrol originally made a big splash in the dietary supplement marketplace due to the fact that intake of it and other polyphenol compounds from red wine may contribute to the “French paradox”—the unexpectedly low rate of death from cardiovascular disease in the Mediterranean population despite a relatively higher intake of saturated fats.2 Then, excitement increased with the understanding that resveratrol helped activate the SIRT 1 gene associated with longevity.3 Since that time, interest in resveratrol has continued to expand due to human research demonstrating its effectiveness for a variety of health benefits, including cognition, mood, inflammation, and immune health. Global resveratrol market revenue was $138 million in 2019 and is projected to reach $228 million in 2025, with a CAGR of 8.57% during 2020-2025.4

NAD promotersNicotinamide adenine dinucleotide (NAD+) is an essential cofactor in all living cells that is involved in fundamental biological processes. Mounting evidence indicates that NAD+ levels decline with age in multiple types of tissues. NAD+ depletion has been associated with hallmarks of aging and may underlie a wide range of age-related diseases.5 Restoration of NAD+ levels in older animals can promote health and support lifespan.6 Nutraceuticals commonly used to promote NAD+ levels include nicotinamide riboside (trademarked Niagen) and nicotinamide mononucleotide (NMN). Although not as commonly used for this purpose, niacinamide is also very effective at increasing NAD+ levels.7

Nutraceuticals for Joint Health

The global joint supplements category is poised to reach over $9.4 billion by the year 2025.8 Some of the more interesting and novel joint support nutraceuticals include cucumber extract and Andrographis paniculata extract.

Cucumber fruit extractDue to its mechanism of reducing TNF-α, a daily dose of only 20 mg—the lowest of any nutraceutical used for treating osteoarthritis—a water extract of cucumber fruit (trademarked Q-Actin) was shown to have greater efficacy than 2,700 mg/day of glucosamine/chondroitin, with a significant improvement in the WOMAC score for physical function, stiffness, and pain of 70.39%, compared to only 33.7% for glucosamine/chondroitin in the same time frame.9

Andrographis paniculata extract The effect of Andrographis paniculata and its andrographolides on NF-κB and inflammation is impressive. Of even greater significance, however, is the human clinical research demonstrating the ability of an Andrographis paniculata extract providing 50% total andrographolides (trademarked ParActin) to safely and effectively reduce joint inflammation (i.e., swollen joints) and joint tenderness in arthritis sufferers. This nutraceutical allowed arthritis patients to discontinue the use of certain medications with serious side effects.10,11

Nutraceuticals for Cognitive Health

The global brain health (cognitive health) supplements market size was valued at $7.21 billion in 2020 and is expected to expand at a CAGR of 8.0% from 2021 to 2028.12 This supplement category offers a plethora of evidence-based nutraceuticals. From my perspective, two particularly interesting such nutraceuticals include ashwagandha extract and a polyphenol-rich extract from French grape and wild blueberry.

Ashwagandha extractAn ashwagandha extract focusing on specific compounds with nootropic bioactivity (trademarked NooGandha) was given in an acute dose to healthy subjects. The results showed sustained attention and increased short-term/working memory.13 To my knowledge, this was the first time a single dose of ashwagandha was shown to have acute cognitive performance benefits. Other research14 with this same ashwagandha extract demonstrated its effectiveness for improving the physiological, cognitive, and psychological effects of stress.

Polyphenol-rich extract from French grape and wild blueberryA polyphenol-rich extract from French grape and wild blueberry (trademarked Memophenol) was given to healthy elderly subjects.15 The results showed that supplementation improved verbal episodic and recognition memory (VRM)-free recall. This same extract was also shown to enhance cognitive performance by 36% 90 minutes after supplementation in healthy university students. Evidence suggests that at least one mechanism of action is that the polyphenols modulate cell and molecular processes involved in learning and memory, including neuronal signaling pathways involved in synaptic plasticity (i.e., the brain’s ability to change and adapt as a result of experience).16

Conclusion

The continued growth of the antiaging supplements market shows no sign of declining anytime soon. There is particular interest in nutraceuticals that can positively impact the aging process itself as well as those that positively impact aspects of human physiology that tend to decline with age, such as joint health and cognitive health. These nutraceuticals include resveratrol, NAD+ promoters, cucumber fruit extract, Andrographis paniculata extract, ashwagandha extract, and a polyphenol-rich extract from French grape and wild blueberry.
