The anti-aging movement is everywhere right now—but instead of trying to stop aging, a better goal is to age well. No combination of powders, pills, or extreme workouts can completely turn back the clock. What we can do is support our bodies, so we feel as strong, energized, and resilient as possible for as long as possible.
It’s also worth keeping healthy skepticism: any supplement claiming to be a cure-all for aging is almost certainly oversimplifying things.
That said, there are a few foundational areas that have an outsized impact on how we age. If you focus here, you’ll be addressing the root causes of many chronic health issues.
The 3 Keys to Healthy Aging are:
- Mitochondrial health
- Blood sugar balance
- Muscle mass maintenance
Mitochondrial Health: Supporting Cellular Energy
Nearly all chronic diseases involve some level of damage to the mitochondria—the parts of your cells responsible for producing energy. Without adequate energy, the body simply cannot repair and maintain itself effectively.
This becomes even more important during times of stress or recovery, such as:
- Chronic illness
- Injury or surgery
- Intense physical activity (like endurance training)
A key player here is NAD+ (nicotinamide adenine dinucleotide), a molecule essential for cellular energy production. NAD+ levels naturally decline with age, while demand increases during stress or illness.
NAD+ is involved in:
- Breaking down glucose for energy
- Driving the TCA (Krebs) cycle
- Fat metabolism (beta oxidation)
- Electron transport within mitochondria
- DNA repair processes
Should Everyone Supplement With NAD+?
Not necessarily. First, it’s good to be aware that most “NAD+” products on the market are precursors to NAD+ such as NMN (nicotinamide mononucleotide) or NR (nicotinamide riboside). Each is converted to NAD+ in different pathways in the body. The jury is out on which form is best.
While NAD+ is essential, balance matters. It plays a role in oxidation-reduction (redox) reactions, and both too much and too little can be problematic. This may explain why some people feel great on supplements initially, then notice the effects taper off—or even reverse.
In addition, once NAD+ is used in the body it must be broken down. One enzyme that is used to break it down is NNMT. This enzyme requires a methyl group. Thus, adding high amounts of NAD+ precursors may present challenges for individuals with the MTHFR gene that have sub-optimal methylation.
For generally healthy individuals, a “pulsing” strategy (cycling on and off NAD+ precursors like NMN or NR) may be more effective than continuous use.
For those managing chronic disease, it’s best to work with a practitioner for a personalized approach.
Blood Sugar Balance: A Cornerstone of Long-Term Health
Blood sugar regulation is tied to nearly every major chronic disease, including:
- Cardiovascular disease
- Type 2 diabetes
- Alzheimer’s and dementia
- Even certain cancers
Maintaining stable blood sugar isn’t just about avoiding sugar, it’s about supporting your body’s ability to process and use glucose effectively.
Key tools for blood sugar balance:
- Diet first
Whole, balanced meals with protein, fiber, and healthy fats are the foundation. - Helpful nutrients
- Chromium: Supports insulin function
- Berberine: A powerful plant compound that can:
–> Improve insulin sensitivity
–> Support glucose metabolism
–> Lower fasting glucose and A1C in studies
- Fiber: Often overlooked, but incredibly important
Why fiber deserves more attention
Fiber supports metabolic health in multiple ways:
- Slows glucose absorption into the bloodstream
- Supports a healthy gut microbiome
- Helps regulate cholesterol
- Binds toxins that may interfere with metabolism
- Promotes production of short-chain fatty acids, which reduce inflammation
Looking beyond daily glucose
A single blood glucose reading only reflects what you’ve eaten recently.
An A1C reading, on the other hand, provides a broader picture—showing average blood sugar levels over about 2–3 months. Some doctors have begun to look at A1C regularly, but ask to have your A1C level checked even if your doctor doesn’t.
Muscle Mass: The Foundation of Strength and Longevity
Muscle isn’t just about appearance—it’s one of the most important tissues for long-term health.
Low muscle mass is strongly associated with:
- Increased risk of cardiovascular disease
- Higher cancer risk
- Greater overall mortality
For those using GLP-1 medications, this is especially important: weight loss can result in muscle loss if not managed carefully.
Why muscle matters as you age:
- Improves glucose metabolism
- Supports balance and prevents falls
- Maintains bone density
- Preserves independence and mobility
How to maintain (or build) muscle
- Protein intake
A general guideline is 1.2 – 1.6 grams of protein per kilogram of body weight per day
(adjusted based on activity level, health status, and medication use) - Targeted nutrients and support
- Creatine: Improves strength, recovery, and muscle hydration
- Collagen peptides: Support connective tissue and recovery
- BCAAs (especially leucine): Stimulate muscle protein synthesis via the mTOR pathway
- HMB: Helps both build muscle via mTOR and prevents muscle breakdown
Some favorite products of mine for supporting muscle mass are Performance Peptides, Collagen Fit (includes Nicotinamide Riboside, a precursor of NAD+), and MyoStim, which provides the nutrients needed to build muscle mass.
Bringing It All Together
Healthy aging isn’t about chasing a miracle supplement—it’s about supporting the systems that keep your body functioning well over time.
Focus on:
- Healthy mitochondria for energy and repair
- Balanced blood sugar for metabolic stability
- Strong muscle mass for resilience and independence
Small, consistent changes in these three areas can have a profound impact on how you feel—not just years from now, but starting today.
