Longevity Starter Stack: NMN + Marine Collagen

Two clinically-studied nutrients. One intelligent daily ritual.

You shouldn't have to choose between feeling sharp and looking vital. The Longevity Starter Stack is designed for those who understand that true wellness runs deeper than the surface — restoring the cellular energy your body produced effortlessly at thirty.

NMN (Nicotinamide Mononucleotide) raises NAD⁺ levels, the coenzyme your cells depend on for energy metabolism, DNA repair, and cognitive function — all of which naturally decline with age. Paired with sustainably sourced Marine Collagen, this stack supports the structural integrity of your skin, joints, and connective tissue from the inside out.

This stack is built for the health-conscious adult in their 40s, 50s, and 60s who values clean, evidence-informed supplementation and refuses to accept decline as inevitable. If you're ready to invest in the biology of longevity, this is your starting point.

Why we made it

• Cellular energy, restored — NMN replenishes NAD⁺ to support mental clarity and sustained physical vitality
• Structural resilience, rebuilt — Marine Collagen delivers the amino acids your skin, joints, and bones need to stay strong
• Clean, purposeful formula — no fillers, no proprietary blends, just two well-researched actives at transparent doses
• Synergistic by design — NAD⁺ metabolism and collagen synthesis share overlapping pathways, making these nutrients more effective together

What's in it

• NMN (Nicotinamide Mononucleotide) — 500mg
  A direct precursor to NAD⁺, the coenzyme central to cellular energy production, DNA repair, and sirtuin activation. Human studies suggest NMN supplementation meaningfully raises NAD⁺ levels in adults over 40.
• Hydrolysed Marine Collagen — 5,000mg
  Sourced from wild-caught fish and enzymatically hydrolysed for superior absorption. Provides Types I and III collagen peptides, the primary structural proteins in skin, tendons, cartilage, and bone matrix. Clinical trials support improvements in skin elasticity and joint comfort within 8–12 weeks.

How to use

Take one serving of NMN with water each morning on an empty stomach, and stir one serving of Marine Collagen into your preferred hot or cold beverage daily.

Common questions

How long before I notice a difference?
Most people report improvements in energy and mental clarity within 2–4 weeks of consistent NMN use. Marine Collagen benefits for skin elasticity and joint comfort are typically observed after 8–12 weeks. Longevity is a long game — we recommend a minimum 90-day commitment to assess your full response.

Is this stack safe to take alongside other supplements or medications?
Both NMN and Marine Collagen have strong safety profiles in published human studies. That said, if you are on prescription medications or managing a health condition, we always recommend consulting your physician before introducing any new supplement protocol.

Why marine collagen specifically, rather than bovine?
Marine collagen peptides are smaller in molecular weight than bovine-derived alternatives, which translates to faster and more efficient absorption through the gut wall. Our source is also sustainably certified and free from common allergens associated with land-animal processing.

What's inside. Every Purelongevity formula is built around clinically-dosed actives drawn from peer-reviewed human trials. We use bioavailable forms (NMN — not niacinamide; magnesium glycinate — not oxide; trans-resveratrol — not the cis isomer) at the doses the literature actually supports. No proprietary blends. No fillers. Every active is listed by name and milligram on the Supplement Facts panel.

What we don't use. Artificial colors. Artificial flavors. Hydrogenated oils. Titanium dioxide. Magnesium stearate. Carrageenan. Soy. Gluten. Dairy. GMOs.
