Where to start?
Supplements and the “longevity-world” can be a real jungle. However the first rule is clear: Don’t take supplements just for the sake of it — and don’t choose things simply because they work for someone else. Your body’s needs are unique. What supports the person next to you on the cross-trainer might not be what you need at all.
Longevity supplements aren’t shortcuts or magic solutions. They’re tools that help your body function the way it’s built to: steady energy, healthy repair processes, better protection against everyday stressors, and a more balanced internal environment.
What do you need?
Find out what your body is asking for. Is your biggest issue sleep? Do you need more energy to get through the day? Are you dealing with stress, slow recovery, or a mix of everything? Once you understand your personal needs, the choices become far clearer.

What do longevity supplements actually do?
Longevity supplements don’t aim to stop aging — they aim to help you age better. To give a clearer overview, we’ve divided them into four areas that each play a role in how your body stays balanced over time. Some of these nutrients consistently appear in research discussing the best longevity supplements, because of the way they support key aging processes.
| Category | Explanation | Supplement examples |
|---|---|---|
| Cell energy & NAD⁺ | NAD⁺ plays a key role in energy production, DNA repair, and metabolic efficiency. Levels decline with age, which can feel like reduced energy and mental sharpness [1]. | NMN, NR, TMG |
| Mitochondria & oxidative stress | Mitochondria become strained over time from oxidative stress, which may lead to fatigue, brain fog, and lower endurance [2]. | CoQ10, GlyNAC, ergothioneine |
| Autophagy & cell renewal | Your body continuously clears out old cells and replaces them with new ones, but this natural renewal process slows down with age [3,4]. | Spermidine, resveratrol, quercetin |
| Inflammation & metabolic health | Ongoing inflammation can influence energy levels, focus, and metabolic balance, and is a known contributor to accelerated aging [5]. | Omega-3, curcumin, berberine |
Cell energy and NAD⁺
Your cells run on energy — and NAD⁺ fuels that system. It’s essential for DNA repair, mitochondrial function, and metabolic efficiency. As we age, NAD⁺ levels fall, which you feel as slower recovery, low energy, and reduced focus.
Supplements like NMN, NR, and TMG are often listed among the most important supplements for longevity, because they help restore NAD⁺ and support overall cellular vitality[1].
Mitochondria and oxidative stress
Mitochondria are your body’s energy factories. Over time, they get damaged by oxidative stress — a form of internal “rusting.” If you often feel drained, foggy, or need extra caffeine just to get through the day, your mitochondria might be waving a white flag.
Compounds like CoQ10, GlyNAC, and Ergothioneine help repair and protect these powerhouses, improving energy at the deepest level [2].
Autophagy and cell renewal
Autophagy is the process your body uses to clear out damaged cells and make space for new, healthier ones. It supports the ongoing renewal your tissues rely on. If you’re interested in a fuller explanation, you can read our blog: Autophagy & cellular clean up: The science of self-renewal, senescence, and longevity.
Supplements such as Spermidine, Resveratrol, and Quercetin promote this natural renewal process, supporting tissue resilience and long-term vitality [3,4].
Inflammation and metabolic health
If you often deal with stiffness, low energy, or brain fog, ongoing inflammation may play a role. Long-lasting inflammatory activity can push the body toward faster aging by placing continuous pressure on cells and tissues.
Research shows that Omega-3, Curcumin, and Berberine can help steady this response. They support healthier blood sugar levels, contribute to cardiovascular well-being, and promote a more balanced metabolic state [5].
The beginner’s longevity supplement list
Many nutrients are increasingly talked about in connection with long-term wellbeing and healthy aging. They aren’t a replacement for the basics, but they may offer support for processes that naturally change over the years.
The list below brings together options often highlighted in the longevity space, giving a clear and simple snapshot of the supplements people most commonly explore when aiming to support their health over time.
Important
If you take medication or have any health conditions, speak with your healthcare provider so you know what’s suitable for your situation.
1. Vitamin D3 + K2 — immunity, mood, bones, balance
Vitamin D plays a central role in how the immune system reacts, how muscles function, and how mood-regulating pathways operate. Many adults spend large parts of the day indoors, leading to low levels year-round. That’s why D3 supplementation is widely recommended in countries with limited sunlight.
K2 works alongside D3 by guiding calcium into bone tissue, supporting long-term bone strength and reducing unwanted calcium build-up in blood vessels [6]. Taken together, they form a solid base for anyone who wants steady, everyday support.
Always a good start to check your levels at your house doctor or via our test: Vitamin D Test Kit.
2. Omega-3 — inflammation, brain health, heart health
EPA and DHA are omega-3 fatty acids that play supportive roles in how the body manages inflammation. They help maintain smoother joint function, steadier cognitive processes, and healthier cell membranes. When levels are low, the body may shift toward higher inflammatory activity, which is linked to issues like sluggish thinking, dry skin, and reduced metabolic balance.
Fatty fish is the richest natural source, but many people don’t consume enough to maintain steady omega-3 levels. In these cases, supplementation can offer consistent support for brain structure, mood regulation, and cardiovascular stability — making omega-3s one of the most important supplements for longevity [7].

3. Magnesium — sleep, recovery, energy
Magnesium is involved in hundreds of reactions that keep the body running smoothly. It helps muscles relax, supports calm nerve activity, and plays a part in nighttime repair processes.
If you struggle with restless legs, tension, or waking up feeling tired, low magnesium could be a factor. Modern diets often fall short, so supplementation can help restore a natural rhythm to sleep and daily energy [8].
4. Collagen or Glycine — joints, tissues, structural support
Collagen forms the framework of your connective tissues. With age, collagen production drops, which can affect joint comfort and skin elasticity. Glycine is needed to build collagen, and newer research suggests the body may not produce enough on its own during stress, illness, or aging [9–11]. Supplementing glycine or collagen can support tissue repair, joint mobility, and overall structural strength — making it a valuable part of longevity-focused nutrition.

5. Creatine — muscle, cognition, resilience
Creatine helps muscles store energy, which becomes more important with age as muscle mass naturally declines. But creatine isn’t only about physical strength — studies show positive effects on memory, mental clarity, and daily performance. If you train, want to preserve muscle as you age, or simply want more stable energy, creatine fits in naturally. With decades of research and a strong safety profile, it consistently appears in top 10 longevity supplements lists [12].

6. NMN or NR — NAD⁺, DNA repair, cellular vitality
NAD⁺ is a molecule every cell depends on for energy production and DNA maintenance. Levels fall steadily with age, which influences how quickly you recover, how energetic you feel, and how efficiently your cells repair damage. NMN and NR help raise NAD⁺ levels, supporting your body’s ability to maintain steady energy and cellular function. They are among the best longevity supplements backed by modern research [13].

7. TMG — methylation and DNA regulation
TMG supports methylation, a process that influences detoxification, gene expression, and cellular repair. Good methylation also helps the body use NAD⁺ more efficiently. For those who take NMN or NR, TMG can act as a helpful partner supplement by keeping methylation pathways balanced and supporting healthy homocysteine levels [14].

8. CoQ10 — mitochondrial protection and energy
CoQ10 is needed for ATP production, the energy source used by every cell. When levels fall, fatigue, heavy legs, or slower physical recovery may appear. As we age, CoQ10 naturally declines, and statins lower it even further. Supplementation offers support for the heart, muscles, and mitochondria, helping your energy system operate more smoothly [15]. It frequently appears on top 10 longevity supplements lists, particularly for adults over 40.
9. GlyNAC — glutathione, oxidative stress, mitochondria
GlyNAC combines glycine and NAC to support glutathione — the body’s main antioxidant. Glutathione levels decrease with age, leaving cells more exposed to oxidative pressure. Research suggests that GlyNAC can improve mitochondrial function, oxidative stress markers, and several hallmarks linked to aging [16]. This makes it a strong option for deeper cellular support.

10. Spermidine — autophagy and renewal
Spermidine helps support autophagy, the body’s way of clearing out old or damaged cells. With age, this natural renewal slows down, which can impact tissue strength and resilience. Supplementation can help keep this process more active, supporting the brain, heart, and metabolic function over time [17].

11. Resveratrol / Pterostilbene — cellular protection
Both compounds belong to the polyphenol family and support sirtuin activity, which plays a part in how cells respond to everyday stress. Pterostilbene is more stable and better absorbed than resveratrol, making it a practical option for consistent daily support [18].

12. Berberine / Dihydroberberine — metabolic balance
Berberine helps regulate insulin sensitivity and blood sugar control, which is essential for long-term metabolic health. A pilot human trial found that a 100 mg or 200 mg dose of dihydroberberine produced significantly higher plasma concentrations of berberine compared to a 500 mg dose of standard berberine, supporting the idea that dihydroberberine is absorbed more efficiently [19]. For many, it may therefore be an easier option to tolerate and use effectively.
Try Purovitalis Berberine Balance: Formulated with dihydroberberine for better absorption and gentler digestion than regular berberine. It’s supported by a blend of complementary nutrients — including Vitamin E, Policosanol, Chromium, and Vitamin K2.
13. Ergothioneine — antioxidant defence and cellular longevity
Ergothioneine is a special antioxidant found mainly in mushrooms — especially varieties like shiitake, oyster, and maitake. Your body even has its own transport system to pull ergothioneine directly into cells, which shows how much it seems to value it. A 2022 study highlights that it collects in sensitive areas like mitochondria and the cell nucleus, where it helps shield your cells from everyday stress. Because of these protective effects across many tissues, researchers are starting to refer to it as a possible “longevity vitamin [20].

14. Curcumin — inflammation and cognitive support
Curcumin is the active component in turmeric and has been widely studied for its ability to regulate inflammatory pathways. According to a review in Foods, curcumin can support joint comfort and immune balance, and may help with mental clarity on days when recovery feels slow or energy is low. That makes it a strong addition for anyone experiencing stiffness, slow recovery, or frequent low-energy days [21].
Supplements: Just one piece of the puzzle
Supplements alone won’t make you live longer — but they can help you live better. They support the base you build with sleep, food, movement, and a steady daily rhythm. Together, those habits shape how you feel today and how your health develops over time.
See your routine as layers you build gradually: start with the fundamentals, add support where your body needs it most, and let the deeper cellular nutrients come in once the basics feel solid. You don’t have to change everything at once. Small adjustments create momentum, and consistency makes the biggest difference.
