Who doesn’t want to live a longer, healthier life? The science of longevity—how we can extend not just our lifespan, but also our “healthspan”—has advanced tremendously over the last few decades. But with so much information out there, it can be hard to know which advice is backed by science and which is just wishful thinking.
In this article, we’ll explore some of the most solid scientific findings about longevity and how you can apply them to your life. And, if you’re curious about the best products to support your health journey, we’ll share our top supplement picks too.
1. The Nine Hallmarks of Aging
A major breakthrough in the field of longevity science was the identification of the nine hallmarks of aging by leading scientists in 2013, published in Cell (López-Otín et al., 2013). These hallmarks include issues like DNA damage, loss of cellular function, and impaired mitochondrial activity. While aging is complex, understanding these hallmarks helps us figure out how to address them and slow the aging process.
But what can you do? Let’s look at some practical ways to improve your health and longevity.
2. Caloric Restriction: Less Is More?
Research has shown that caloric restriction (CR), or eating fewer calories while maintaining proper nutrition, can extend lifespan in animals like mice and monkeys. Studies dating back to 1935 first observed this in rodents (Journal of Nutrition), and later studies in rhesus monkeys published in Nature Communications in 2017 confirmed that CR improved healthspan, though not all studies saw lifespan extension in primates (Colman et al., 2017).
While the evidence in humans is less clear, CR has been linked to improved health outcomes, including better metabolic health and a lower risk of age-related diseases like diabetes and heart disease (The Lancet Diabetes & Endocrinology, 2015).
Rather than focusing on strict caloric restriction, some people prefer intermittent fasting—restricting eating to certain hours of the day—which has been shown to provide similar health benefits, such as improved insulin sensitivity and reduced inflammation (Cell Metabolism, 2018). While we can’t say for sure that either approach extends human lifespan, both offer promising strategies for improving overall health and longevity markers.
3. Boost Your NAD+ Levels
As we age, the levels of a critical molecule called NAD+ decline in our bodies. NAD+ is essential for many biological processes, including repairing damaged DNA and keeping our cells functioning. Research in animal models, including studies published in Science in 2016, suggests that boosting NAD+ levels may help improve healthspan and reverse some aspects of aging (Zhang et al., 2016). However, research in humans is still emerging, and while NAD+ boosters like NMN and NR have shown promise in early studies, larger trials are needed to confirm their long-term effects on aging (Nature Communications, 2018).
Supplements like NMN (nicotinamide mononucleotide) or NR (nicotinamide riboside) have been shown to increase NAD+ levels in humans (Cell Reports, 2016), although more research is needed to fully understand their impact on aging. For those looking to try a high-quality NAD+ booster, Elysium Basis [Amazon] is one of the most respected products on the market, containing both NR and pterostilbene to support cellular health.
4. Mitochondria: The Powerhouses of Your Cells
Ever wonder why you feel more tired as you get older? One of the reasons could be your mitochondria—the “power plants” inside your cells that produce energy. Over time, mitochondrial function declines, which leads to reduced energy levels and poorer cellular function. Scientists now recognize mitochondrial dysfunction as a key driver of aging.
Fortunately, there are ways to support mitochondrial health. A well-supported supplement for mitochondrial function is CoQ10, which helps improve energy production in cells and may reduce fatigue. Studies published in Frontiers in Physiology in 2018 highlighted CoQ10’s role in supporting mitochondrial function and energy production (Hernández-Camacho et al., 2018). Qunol Ultra CoQ10 100mg [Amazon] is a top-rated option that’s easily absorbed by the body, making it an excellent choice for those looking to enhance their energy and mitochondrial health.
5. The Role of Collagen for Longevity
As we age, the production of collagen, the protein that helps keep our skin, joints, and tissues strong, slows down. This contributes to wrinkles, joint pain, and reduced mobility. A meta studie published in 2019 furthermore shows that supplementing with collagen peptides can help improve skin elasticity and hydration, as well as joint health.
For those looking to improve their collagen levels, we recommend Vital Proteins Collagen Peptides [Amazon], which contains highly bioavailable collagen.
Conclusion: A Balanced Approach to Longevity
The science of longevity is advancing, and while there’s no magic pill to stop aging, there are ways to support a longer, healthier life. Focusing on well-studied strategies—like supporting your NAD+ levels, improving mitochondrial health, and getting enough collagen—can help make a real difference.
