Top 5 Anti-Aging Supplements That Actually Work, According to Longevity Experts

Let’s face it—aging is inevitable. But what if we could age better? What if we could move with ease, keep our minds sharp, and glow from the inside out, all while celebrating another birthday? That’s the promise behind today’s best anti aging supplements. And according to leading longevity experts, there are now scientifically backed ingredients that actually help slow down the aging process.

Whether you’re in your 30s and want to get ahead of the game, or you’re in your 50s looking to turn the clock back a little, this guide is for you. We’ve rounded up the top five anti-aging supplements that are supported by science, approved by wellness pros, and readily available for Canadians looking to upgrade their health game.

Why Supplements Matter for Healthy Aging

Before we jump into the list, let’s get something straight: no pill is a magic bullet. But many health supplements in Canada now contain powerful compounds that target aging at its root—cellular health, inflammation, and oxidative stress.

As we age, our bodies produce fewer of the compounds that keep us energized, wrinkle-free, and mentally focused. Supplements can help fill in those gaps and optimize how we age—not just how long we live.

Longevity specialists and researchers emphasize that certain ingredients can help protect your DNA, boost energy-producing mitochondria, and reduce chronic inflammation. The key? Choosing supplements that are backed by evidence and used in clinical-grade doses.

Ready to meet the top contenders? Here we go.

1. NMN (Nicotinamide Mononucleotide) – The Cellular Energy Booster

Why it works: NMN is one of the hottest anti-aging discoveries of the past decade. It’s a precursor to NAD+—a molecule that fuels your cells and declines rapidly as you age.

When NAD+ levels drop, everything from your metabolism to your brain function starts to suffer. NMN works by restoring those levels and supporting mitochondrial health—meaning more energy, sharper focus, and improved skin elasticity.

What experts say: Dr. David Sinclair of Harvard Medical School (a pioneer in longevity research) is a strong proponent of NMN. His research shows it may help slow the aging process at the cellular level.

Recommended dose: 250–500 mg per day, taken in the morning.

Look for: Purity-tested NMN in capsules, ideally paired with resveratrol for added antioxidant support.

2. Collagen Peptides – The Skin, Joint, and Hair Reviver

Why it works: Collagen is the protein that keeps your skin plump, your joints flexible, and your hair strong. Starting in your 20s, your natural collagen production drops by about 1% each year. By your 50s? You're likely producing half as much as you did in your youth.

Supplementing with hydrolyzed collagen peptides helps replenish those stores, improve skin hydration, and reduce wrinkles. It's also great for joint support and gut health.

What experts say: A 2021 meta-analysis published in the Journal of Cosmetic Dermatology confirmed that oral collagen supplements improve skin elasticity, hydration, and dermal collagen density over time.

Recommended dose: 10–15g daily. Look for grass-fed, hydrolyzed collagen peptides for better absorption.

Pro tip: Mix it into your morning smoothie or coffee—it’s virtually tasteless!

3. Curcumin with Black Pepper (BioPerine) – The Inflammation Fighter

Why it works: Chronic inflammation is one of the leading contributors to aging and age-related diseases. Curcumin, the active compound in turmeric, has potent anti-inflammatory and antioxidant properties.

But here’s the catch: curcumin has notoriously low bioavailability. That’s why curcumin supplements with piperine (black pepper extract) are the gold standard—they dramatically improve absorption.

What experts say: Curcumin is one of the most researched anti-aging compounds in the world. Studies show it supports cognitive function, joint health, cardiovascular health, and may even protect against neurodegeneration.

Recommended dose: 500–1,000 mg of curcumin standardized to 95% curcuminoids, combined with at least 5mg of piperine.

Bonus: Some formulas also include ginger extract for synergistic anti-inflammatory effects.

4. Resveratrol – The Longevity Polyphenol

Why it works: Resveratrol is a plant compound found in red wine and certain berries that’s famous for activating sirtuins—the so-called “longevity genes.”

It acts as a powerful antioxidant, protecting your cells from oxidative stress, a key driver of aging. When paired with NMN, resveratrol may amplify the effects of NAD+ restoration.

What experts say: Longevity researchers believe that resveratrol mimics the effects of calorie restriction, a proven method for extending lifespan in various organisms. While results in humans are still being studied, early data looks promising.

Recommended dose: 150–500 mg daily. Look for trans-resveratrol (the active form), preferably micronized for better absorption.

Pro tip: Resveratrol is fat-soluble—take it with a meal that includes healthy fats for best results.

5. Omega-3 Fatty Acids (EPA & DHA) – The Brain and Heart Protector

Why it works: Omega-3s are essential fats that reduce inflammation, support brain function, and improve heart health. They also help maintain skin hydration and elasticity—yes, your fish oil could be your secret beauty weapon!

As we age, our risk of cognitive decline and cardiovascular issues increases. Supplementing with high-quality omega-3s can be a major line of defense.

What experts say: Multiple studies show that omega-3 supplementation can slow cognitive aging, reduce depression risk, and lower triglycerides—key metrics of aging well.

Recommended dose: 1,000–2,000 mg of combined EPA and DHA daily. Make sure the product is third-party tested for purity and heavy metals.

Look for: Triglyceride form (not ethyl ester) for better absorption.

Are These Supplements Safe?

For most healthy adults, the above supplements are safe when taken at recommended dosages. However, it's always smart to consult your healthcare provider—especially if you're on medication or managing chronic conditions.

Canadians have the added advantage of choosing from top-tier Health supplements Canada brands that comply with strict safety and quality standards. Products that carry an NPN (Natural Product Number) have been reviewed and approved by Health Canada.

Choosing the Right Brand in Canada

When shopping for the best anti aging supplements, quality is everything. Don’t be swayed by fancy packaging or too-good-to-be-true claims. Look for brands that:

Are transparent about ingredient sourcing

• Use clinical-grade dosages
• Are third-party tested for purity and potency
• Provide certificates of analysis (COAs)
• Are manufactured in GMP-certified facilities

One standout name in the Canadian market is Physicians Research. Known for its science-driven formulas and commitment to evidence-based ingredients, the brand offers a wide range of health supplements ideal for anyone serious about healthy aging.

Bonus Tips to Maximize Supplement Benefits

Taking supplements is just one part of the longevity puzzle. Here are some daily habits to supercharge your anti-aging strategy:

Eat a Colorful Diet

Load up on leafy greens, berries, and healthy fats. Antioxidants from food work hand-in-hand with your supplements.

Stay Active

Exercise increases circulation, supports detox, and helps your body utilize nutrients more efficiently.

Prioritize Sleep

Your body repairs and regenerates while you sleep. Aim for 7–9 hours of quality rest.

Manage Stress

Chronic stress accelerates aging. Try breathwork, journaling, or even a quick walk to reset your nervous system.

Get Outside

Sunshine boosts mood and vitamin D levels. Just don’t forget your SPF!
