The Ageless Labs Longevity Supplement Ingredient Guide is a plain-English reference to the compounds most discussed in healthy-aging research. For each ingredient you'll find what it is, the mechanism people care about, commonly studied dosage ranges, the best time to take it, and what to pair it with. This is an educational resource, not medical advice — always talk to a qualified healthcare provider before starting any new supplement, especially if you're pregnant, nursing, taking medication, or managing a health condition.
New here? If you're not sure where to start, a Complete Multivitamin is the simplest first step — a full-spectrum daily foundation you can layer more targeted ingredients on top of as your goals get more specific.

Longevity & Cellular Health
These compounds are studied for their roles in cellular energy production, NAD+ metabolism, and antioxidant defense — the biological themes most associated with healthy aging.
NMN (Nicotinamide Mononucleotide)
What it is: A direct precursor the body uses to produce NAD+, a coenzyme central to cellular energy and repair pathways. NAD+ levels are widely reported to decline with age.
Commonly studied range: 250–900 mg per day in human studies, most often taken as a single morning dose.
Best time: Morning, with or without food. Some people split into two doses.
Pairs well with: Resveratrol (often discussed together as a longevity pairing) and a source of healthy fat.

NAD+
What it is: The coenzyme itself, involved in hundreds of metabolic reactions including mitochondrial energy production and DNA-repair signaling.
Commonly studied range: Supplemental products vary widely; precursor forms (NMN, NR) are the more heavily researched route to raising NAD+.
Best time: Morning, to align with the body's daytime energy demands.
Pairs well with: CoQ10 and B-vitamins that participate in energy metabolism.
Learn more: NAD+
Resveratrol
What it is: A polyphenol antioxidant found in grape skins and Japanese knotweed, studied for activating sirtuin pathways associated with cellular stress resistance.
Commonly studied range: 150–600 mg per day. Ageless Labs uses a 50% extract at 600 mg.
Best time: With a fat-containing meal — resveratrol is fat-soluble and absorbs better with dietary fat.
Pairs well with: NMN or NAD+ precursors.
Learn more: Resveratrol 600mg
CoQ10 (Ubiquinone)
What it is: A fat-soluble compound essential to the mitochondrial electron-transport chain — the cell's energy factory. Natural production is reported to decline after roughly age 40.
Commonly studied range: 100–300 mg per day. Ageless Labs provides 200 mg per serving.
Best time: With a meal containing fat, for absorption.
Pairs well with: Omega-3 fish oil (both fat-soluble, both studied for cardiovascular support).

Glucosamine, MSM & Turmeric (Joint Support)
What it is: A blend of joint-focused compounds — MSM, glucosamine HCl, turmeric, and Boswellia serrata — studied for supporting joint flexibility and comfort as part of an active, healthy-aging lifestyle.
Commonly studied range: Glucosamine is often studied around 1,500 mg per day; turmeric extract ranges vary widely by curcumin concentration. Look for products standardized to boswellic acid or curcumin content.
Best time: With a meal, split across morning and evening doses if using two capsules.
Pairs well with: Collagen Peptides and Omega-3, both studied for joint and connective-tissue support.

Brain & Cognitive
Omega-3 (EPA & DHA)
What it is: Long-chain fatty acids from fish oil. DHA is a major structural fat in the brain; EPA is studied more for its role in the body's inflammation response.
Commonly studied range: 250–1,000 mg combined EPA+DHA per day for general wellness. Ageless Labs provides EPA 180mg + DHA 120mg per serving.
Best time: With a meal, to reduce fishy aftertaste and aid absorption.
Pairs well with: CoQ10, Vitamin D3 (all fat-soluble).

Lion's Mane & Functional Mushrooms
What it is: Lion's Mane is studied for nerve-growth-factor pathways and cognitive support; Reishi for calm and immune balance; Cordyceps for energy; Chaga for antioxidant content.
Commonly studied range: Varies by mushroom and extract concentration; look for products standardized to beta-glucan content.
Best time: Lion's Mane and Cordyceps in the morning for focus and energy; Reishi in the evening for calm.
Pairs well with: Omega-3 for cognitive routines.

Sleep & Stress
Magnesium Glycinate
What it is: Magnesium bound to the amino acid glycine, a form chosen for high bioavailability and gentleness on the stomach. Magnesium participates in hundreds of enzymatic reactions, including those involved in muscle relaxation and the nervous system.
Commonly studied range: 200–400 mg elemental magnesium per day.
Best time: Evening, 30–60 minutes before bed — glycine itself is associated with sleep quality.
Pairs well with: Ashwagandha for an evening wind-down routine.
Learn more: Magnesium Glycinate
Ashwagandha (KSM-66)
What it is: An adaptogenic herb studied for supporting the body's stress response and healthy cortisol balance. KSM-66 is a well-researched root extract.
Commonly studied range: 300–600 mg per day of a standardized extract.
Best time: Flexible — evening if you use it for wind-down, or split morning/evening for all-day stress support.
Pairs well with: Magnesium Glycinate.

Melatonin, Valerian & L-Tryptophan (Sleep Formula)
What it is: A blend built around 2 mg of melatonin alongside Valerian Root, Chamomile, GABA, L-Tryptophan, Lemon Balm, and Passion Flower — ingredients studied individually for supporting a natural wind-down before bed.
Commonly studied range: Melatonin is commonly studied at 0.5–5 mg; most sleep-support products land in the 1–3 mg range.
Best time: 30–60 minutes before bed, consistently at the same time each night.
Pairs well with: Magnesium Glycinate and Ashwagandha for a complete evening routine.

Skin, Hair & Nails
Collagen Peptides (Hydrolyzed)
What it is: Collagen broken into small peptides for easier absorption. Studied for supporting skin elasticity, hydration, and joint comfort. The body's natural collagen production declines with age.
Commonly studied range: 2.5–15 g per day; 10 g is a common daily serving.
Best time: Any time — consistency matters more than timing. Mixes into coffee or a smoothie.
Pairs well with: Vitamin C, which is a cofactor in collagen synthesis.

Biotin & Hair-Skin-Nails Blends
What it is: Biotin (Vitamin B7) supports keratin infrastructure; typically combined with Vitamins A, C, E and antioxidants in beauty formulas.
Commonly studied range: Biotin is commonly included at 2,500–10,000 mcg in beauty products.
Best time: With a meal for the fat-soluble vitamins in the blend.

Frequently Asked Questions
Can I take multiple supplements at once?
Many people build a “stack” of complementary supplements. The timing chart above helps you group them sensibly — fat-soluble compounds with meals, magnesium in the evening, energy-oriented compounds in the morning. If you'd like help assembling a routine around a specific goal, our Build Your Stack tool walks you through it in about 60 seconds.
What does “commonly studied range” mean?
It's the span of daily amounts that appear most often in published human research and commercial products. It is not a prescription. Your ideal amount depends on your body, diet, and health status — which is why we point you to a healthcare provider for anything personalized.
Are these supplements third-party tested?
Ageless Labs products are made in the USA in GMP-certified facilities. GMP (Good Manufacturing Practice) certification covers quality and consistency standards throughout production.
How long until I notice a difference?
It varies by ingredient and goal. Some effects (like magnesium's role in an evening routine) are felt relatively quickly, while structural or cellular-health benefits are studied over weeks to months of consistent use. Consistency is the single biggest factor.
