What a Pharmacist Says About Longevity Supplements

Longevity supplements are often marketed like a shortcut to healthy aging—but in Brello’s webinar Smart Supplementing: What Helps and What to Skip, pharmacist and functional nutritionist Stephanie Chan, PharmD, FDN-P kept the conversation grounded: dietary supplements may help most when they fill a real need, not when they stack on top of an already crowded routine.¹⁷

If you’ve ever stood in the supplement aisle thinking, “What am I even supposed to buy?”—you’re not alone. Chan said she often sees people show up with “20 bottles” of nutritional supplements, many of which may not match a clear goal.¹⁷

This is for informational purposes and isn’t medical advice.

Why longevity supplements can feel confusing

The supplements industry is loud, fast, and trend-driven—so it’s easy to lose sight of basics like dietary intake, essential nutrients, and whether something is doing anything at all.^4,14

Chan’s framing was simple: supplements may make sense when they help you:

• bridge nutritional deficiencies from diet shifts (keto, gluten-free, calorie cuts)
• support higher-demand seasons (stress, heavy training, travel, calorie deficit)
• account for absorption challenges (gut issues, fast transit, disrupted digestion)¹⁷

It’s also worth remembering: more pills doesn’t automatically equal more health benefits—and high doses or excessive doses can create new problems or new variables.^4,17

When longevity supplements might help

1) When your diet has gaps

Diet changes can reduce variety—especially when people lean hard on lean proteins, vegetables, and smaller portions.¹⁷ That can sometimes create gaps that affect energy, focus, and how steady your routine feels. This can also come up when people experiment with meal timing or intermittent fasting for sustainable weight loss without a clear nutrition plan.

Common “gap” nutrients people often check include:

• Vitamin D (including questions around vitamin D deficiency / low vitamin D levels) for bone health, immune function, and general wellness.³
• Vitamin C (often listed as ascorbic acid) for antioxidant support and tissue maintenance.¹⁰
• Vitamin E (including supplemental vitamin E) as part of antioxidant defenses.⁹

Food-first still matters: green leafy vegetables, whole grains, citrus fruits, and adequate protein support a strong base before any supplemental vitamin is added.⁴

Note: People also ask about vitamin D and blood pressure, but supplement decisions are worth grounding in the specifics of your overall routine and guidance from a healthcare professional (rather than marketing headlines).^3,4

2) When life is high-demand

Chan compared the body to a car: if your body needs to operate at a higher capacity (stress, intense training, endurance goals) but you fuel the same—or less—your reserves can drain faster.¹⁷

This is where people often notice changes in:

• energy and focus (cognitive function)
• mood and mental health strain
• sleep quality shifts
• a sense that they’re not recovering well during a hard season¹⁷

3) When digestion or absorption is off

Your gut plays a vital role in absorbing nutrients from food and dietary supplements.^8,17 If digestion is off (or transit is too fast), even “good” supplements may not land the way you expect.

Red flags to watch for

“More isn’t always better”

Chan’s repeated caution: mega-stacks can overwhelm routines—and high doses aren’t automatically better unless they match a real need.¹⁷

Influencer picks and exaggerated claims

Chan noted the mismatch problem: online recommendations may not align with your goals, your health status, your body weight, or your current routine.¹⁷
She also reminded viewers that supplement companies can’t claim to cure or treat conditions—so disease-linked language should raise your skepticism.^14,17

A quick example of what “skeptic mode” looks like:

• If a product implies it can prevent or treat prostate cancer, cardiovascular disease, or any other chronic disease, treat that as a red flag and verify what it’s actually allowed to claim.¹⁴

Medication and longevity supplements interactions

Chan emphasized that supplements can interact with medications and sometimes with each other (more on that below).¹⁷

Low-quality brands

Because supplements aren’t regulated like prescription drugs, she encouraged looking for quality signals—especially third-party testing.^14,17

“Test, don’t guess”

Chan used “test, don’t guess” as a rule of thumb—sometimes with labs, sometimes by paying attention to symptom patterns.¹⁷ The point isn’t self-diagnosis; it’s avoiding random buying.

She gave magnesium as a practical example: it’s involved in many body processes (including roles in cellular energy production and overall cellular function), and some people associate low magnesium with patterns like cramps or sleep issues.^2,17

Common longevity supplements mistakes (and how to avoid them)

Taking everything at once

Starting five things at once can make it hard to tell what helped—especially if energy, brain health, mood, digestion, or skin health changes over time.¹⁷

Forgetting nutrient “competition”

Chan specifically mentioned mineral competition: for example, iron and calcium can compete for absorption.^15,17

Ignoring fat-soluble vitamins

Chan called out the fat-soluble group—A, D, E, K—which generally absorb better with food (because fat helps absorption).^5,17
That matters if you’re taking vitamin d or vitamin e as part of a routine.^3,9

Quality check (label-reading, simplified)

Chan’s approach: keep it boring, clear, and verifiable.¹⁷

Pharmacist’s longevity supplements label-reading checklist

What to look for	What to be cautious with
Third-party seals (USP / NSF)	Proprietary blends (hidden amounts)
Bioavailable forms	Artificial colors, fillers, extra dyes
Clear serving size and dose	“One-a-day” claims that sound too perfect
Simple ingredient list	Mega-doses without clear rationale

A quick evidence note: “popular” is not the same as “proven.” For many ingredients, the best data comes from randomized controlled trials—and some trends still lack solid scientific backing.⁴

The “science behind the habit” (in plain English)

This is where longevity supplements marketing loves big words. Here’s the calmer version.

Cellular energy, mitochondria, and energy production

A lot of “longevity” talk circles back to cellular energy and energy production. Nutrients like magnesium play a role in many processes tied to how the body uses energy, which connects to cellular energy production and broader cellular function.²
You’ll also see terms like mitochondrial function used in these conversations; the key is keeping the claim realistic and evidence-based, not hype-based.⁴

Oxidative stress and reactive oxygen species

“Oxidative stress” is commonly described as an imbalance where reactive oxygen species (ROS) and similar byproducts outpace the body’s antioxidant defenses.^9,10 This is why you’ll see longevity supplement labels talk about “antioxidant properties,” “potent antioxidant properties,” and “combat oxidative stress.”

In general education sources, vitamins like vitamin c (ascorbic acid) and vitamin e are frequently discussed in the context of antioxidant roles.^9,10 Ingredients like alpha lipoic acid also show up in longevity discussions, with evidence that varies by context.¹⁶

DNA repair, cellular aging, and cellular senescence

Researchers study cellular senescence (a kind of “retirement mode” for older cells) and broader cellular aging as part of the overall aging process.¹ The big-picture goal is a better health span—more years of steady function—not just adding time. If you want the bigger-picture definition, this guide to what longevity means breaks down lifespan, life expectancy, and healthspan in plain English.¹

Systemic inflammation and cardiovascular risk

Long-term, low-grade systemic inflammation is often discussed alongside cardiovascular risk, chronic disease patterns, and overall aging biology.¹² You may also see markers like c reactive protein referenced in inflammation conversations, but it’s worth keeping expectations realistic: supplements aren’t a guaranteed lever, and lifestyle often carries a lot of weight here.^12,4

Webinar Q&A: what people actually asked

Gummies: helpful or hype?

Chan said gummies can improve adherence, but she flagged two common issues:

• extra sweeteners/colors
• lower doses or limited forms (she couldn’t find magnesium glycinate gummies for her child)¹⁷

Hair loss supplements

Chan said hair loss can have different causes (hormonal patterns, stress/thyroid, nutrient intake). She mentioned Nutrafol as a well-known option people ask about and stressed consistency because hair changes often lag by months.¹⁷
She also noted collagen and biotin are common topics; collagen often gets discussed in relation to hair and skin elasticity (and broader skin health) as people get older.¹⁷

Vitamin C, elderberry, respiratory infections

Chan said vitamin C is often a reasonable “food-first or supplement” conversation (with citrus fruits as a food-first option).^10,17 This comes up a lot during cold season when people worry about respiratory infections and the immune system.^10,17

Patches

Chan didn’t rule patches out, but she noted absorption can vary by person (skin thickness, hydration, and other factors).¹⁷

“I have a cabinet full of supplements.” Here’s the reset Chan suggested.

Chan’s reset was practical: 1) check expiration dates and storage
2) ask “why am I taking this?”
3) ask “is this helping me?”¹⁷

If you can’t answer those, simplifying is often more useful than adding more.

If you want a simple “start here” foundation

Chan shared a “top three” that many people consider foundational:

1) Magnesium (often used in the evening because it can feel calming)^2,17
2) A probiotic (because gut function affects absorption)^8,13,17
3) Omega-3 / fish oil (especially if you don’t eat seafood regularly; quality matters)^6,17

She also noted that diet style matters: for example, people who don’t eat much meat sometimes explore B vitamins, since some B vitamins are commonly found in animal foods.¹⁷

She mentioned ingredients people ask about online (with evolving evidence) like alpha lipoic acid and calcium alpha ketoglutarate—with a reminder that marketing often outpaces certainty.^16,17

What “support healthy aging” can look like

Longevity supplements may support healthy aging when they strengthen a foundation—not when they replace it. For readers who want a more structured wellness foundation beyond supplements alone, What Is Brello Rise? explains Brello’s broader approach to daily support.

A realistic “support healthy aging” routine usually starts with:

• a healthy diet (color, fiber, protein—think green leafy vegetables, whole grains, lean proteins)
• sleep and stress habits that protect sleep quality and reduce chronic load
• supplements chosen for nutritional deficiencies or clear goals—not just marketing^4,17

That foundation supports:

• cardiovascular health and heart health (patterns that influence long-term cardiovascular disease risk)^6,12
• brain health and cognitive function (especially when sleep and diet are stable)¹²
• joint health, skin health, and overall health as part of a steady, sustainable routine.⁴

For older adults and aging populations, the “boring basics” often matter more than exotic claims—because long-term outcomes are shaped by consistency, not novelty.⁴

Final Thoughts

Longevity supplements can play a role in healthy aging, but the best results usually come from keeping things simple: start with a healthy diet, fill real nutrient gaps, and choose quality dietary supplements with clear labels and third-party testing. Watch for exaggerated claims, proprietary blends, and high doses that don’t match your goals. When you track how you feel—energy, sleep quality, focus—you can reassess what’s worth keeping. Small, steady habits support cellular health far better than a cabinet full of bottles. If building those routines feels harder than it sounds, this guide on how long it takes to form a habit can help make the process feel more realistic.
