Longevity supplements have gone from niche to mainstream, and if you are trying to make sense of NAD+, CoQ10, and glutathione, this 2026 guide breaks down what each one is and where it fits. The healthy-aging aisle can feel intimidating, full of unfamiliar names and big promises, so the goal here is a plain-English explanation of the popular ingredients, plus a realistic reminder that the basics still matter. This is educational information, not medical advice, so treat it as a starting point and talk to your doctor before adding anything new.
Throughout, we use Solaray as a reference point, because the brand carries many of these formulas under one roof and has been a recognizable name in the category since 1973. If you want the broader picture first, our roundup of the best supplement brands sets the scene.
What People Mean by Longevity Supplements
The phrase covers a loose group of ingredients associated with cellular energy, oxidative balance, and healthy aging rather than any single miracle pill. Some, like NAD+ precursors, are newer to the mainstream conversation. Others, like CoQ10, have been studied and sold for decades. What they share is a focus on the machinery your cells use to produce energy and manage everyday stress. No supplement replaces sleep, movement, and a good diet, but for people who already have the fundamentals in place, these are the ingredients they tend to ask about next.
NAD+
NAD+ is a coenzyme involved in cellular energy production, and interest in supporting its levels has driven a wave of new products. Because NAD+ itself is a large molecule, delivery format is a common talking point, which is why you will see liposomal versions designed to aid absorption. Solaray's Liposomal NAD+ is an example of this approach, packaging the ingredient in a liposomal delivery system. If NAD+ is the ingredient that first pulled you toward the longevity aisle, it is worth understanding that how it is delivered can matter as much as how much is in the bottle. You can see the format at Solaray.
CoQ10 and Ubiquinol
CoQ10 is one of the most established names in this space, a compound your cells use in energy production and one that naturally becomes a focus as people age. It comes in two main forms: ubiquinone and ubiquinol, the latter being the already-converted, body-ready version that many shoppers prefer. Solaray's CoQ-10 Ubiquinol delivers 100 mg in that ubiquinol form, which is a straightforward way to add it to a routine. If you take a statin or simply want to support everyday energy, CoQ10 is often one of the first longevity ingredients people try, and the ubiquinol form is a sensible default.
Glutathione
Often called the body's master antioxidant, glutathione is a compound involved in managing oxidative stress. Like NAD+, it faces an absorption challenge in supplement form, so liposomal delivery is again a common solution. Solaray's Liposomal Glutathione uses that approach to help the ingredient survive digestion. For anyone building an antioxidant-minded routine, glutathione tends to sit alongside vitamin C and other supportive nutrients rather than standing alone. As always, the delivery format is part of what you are paying for, so it is worth reading the label rather than comparing on milligrams alone.
Do Not Forget the Basics
Chasing exotic ingredients while ignoring the fundamentals is the most common mistake in this category. Minerals and muscle support do more for healthy aging than most people give them credit for. Magnesium is a foundational mineral, and Solaray's Opti-5 Magnesium is one option; our guide to the best magnesium supplements goes deeper. Maintaining muscle matters as you age too, which is where creatine and targeted formulas come in. Solaray offers a Creatine + MBP and an HMB + Vitamin D3, both aimed at muscle and strength support. For more on that, see our roundup of the best creatine monohydrate. And if you have not nailed a daily foundation yet, start with our guide on how to choose a daily multivitamin.
Why Brand Quality Matters Here
With longevity ingredients, you are often paying for absorption technology and ingredient quality, not just the compound itself, so the brand behind the bottle matters. Solaray bills itself as a number one vitamin and mineral brand and has been sourcing ingredients and building formulas since 1973, which is a long track record in a category full of newcomers. That does not mean it is the only good option, but it is a reasonable benchmark when you are comparing labels. Explore the full healthy-aging lineup at Solaray.
Building a Simple, Sensible Routine
If you want a practical way to approach this category, build from the ground up rather than the trend down. Start with the foundations that support everyday function, a quality multivitamin, adequate magnesium, and enough protein, and give them a few weeks before judging how you feel. From there, add one longevity-specific ingredient at a time, such as a ubiquinol-form CoQ10, so you can actually tell what is doing what. Introducing five new things at once tells you nothing if something changes. Pay attention to quality signals on the label, including the ingredient form, the delivery system, and whether the brand is established, since absorption and consistency matter more than a big number on the front of the box. And keep expectations grounded: these are supportive additions to sleep, movement, and diet, not substitutes for them. Above all, talk to your doctor before starting anything new, especially if you take medication or have a health condition.
Frequently Asked Questions
Are longevity supplements proven to extend lifespan?
No supplement is a proven fountain of youth. Ingredients like NAD+, CoQ10, and glutathione are associated with cellular energy and antioxidant support, but they are best viewed as one part of a healthy routine, not a replacement for sleep, exercise, and diet. Speak with your doctor before starting any new supplement.
What does liposomal mean on the label?
Liposomal refers to a delivery format that packages an ingredient to help it survive digestion and absorb more effectively. You will see it on ingredients like NAD+ and glutathione that are otherwise hard for the body to take up, including Solaray's liposomal versions.
Which ingredient should a beginner start with?
Most people are better served by nailing the basics first, such as a quality multivitamin, magnesium, and adequate protein, before layering in CoQ10 or NAD+. Ubiquinol-form CoQ10 is a common, well-established first step in the longevity category.
