The quiet truth

You don't know who to trust in the supplement space.
Neither did we.

That's why we built Coastline. As busy parents, we wanted something we could trust — not trends or hidden doses, but the most evidence-backed compounds for longevity, at the doses that actually work.

The Coastline system

Two steps. One complete system.

Morning

Morning Blend + Softgels

Blend + Softgels

10 ingredients with breakfast. Energy, focus, muscle, gut health.

Mix one scoop of the Morning Blend with water and take one softgel with your first meal. Creatine, taurine, and glycine fuel your muscles and mind. CoQ10 and astaxanthin protect your cells. Ergothioneine crosses the blood-brain barrier for long-term neuroprotection.

Evening

Evening Capsules

Evening Capsules

3 ingredients before bed. Sleep, recovery, brain health.

Take two capsules 30-60 minutes before bed. L-theanine calms the mind and improves sleep architecture. Glycine deepens sleep quality. Lithium orotate supports mood and long-term neuroprotection at a safe trace dose.
Get Started

What's inside

13 foundational ingredients

Creatine5.25g+ Buffers cellular energy production, keeping muscles strong and powerful throughout the day. Shown to accelerate muscle gains, improve bone density, and sharpen cognitive function during stress and sleep deprivation. Also reduces cellular waste accumulation linked to aging.
Glycine5g+ Improves sleep quality and reduces daytime sleepiness while boosting alertness and memory. A building block for collagen and a precursor for glutathione, your body's master antioxidant. Also shown to reduce blood sugar swings and lower inflammatory markers linked to aging.
Inulin4g+ Prebiotic fiber that feeds beneficial gut bacteria and counters the gut dysbiosis that accelerates aging. Creates short-chain fatty acids that improve blood sugar control, reduce inflammation, and increase mineral absorption — especially calcium for bone health. Evidence suggests it also supports cognition and mood.
Taurine3.05g+ The most abundant amino acid inside your cells, shown to extend lifespan 10-12% in animal models. Reduces blood pressure, lowers LDL cholesterol and triglycerides, and improves fasting blood sugar. Also enhances endurance performance, reduces chronic inflammation, and targets nearly all hallmarks of aging.
Magnesium150mg+ Cofactor for 300+ enzymes and associated with a 6% reduction in all-cause mortality per 100mg increase. Clinically demonstrated to reduce blood pressure, improve blood sugar control, and enhance insulin sensitivity. Also speeds sleep onset by ~17 minutes and helps muscles recover faster from exercise.
Ergothioneine5mg+ A rare amino acid with exceptional antioxidant power that crosses the blood-brain barrier and accumulates there. Shown to extend lifespan in animal models and improve cognitive function and memory. Also increases NAD+ levels in cells and protects mitochondrial DNA from damage.
CoQ10200mg+ Essential for your mitochondria to produce ATP (cellular energy) and acts as a potent antioxidant protecting cell membranes. Clinically demonstrated to reduce migraine frequency and duration, improve heart health, and reduce inflammatory markers. Also offsets negative effects of statin medications.
Lutein10mg+ Accumulates in the macula where it filters harmful blue light, reducing the risk of age-related macular degeneration. Beyond eye protection, shown to improve word learning, attention, memory, and reasoning. Also protects skin against UV radiation and increases skin elasticity and hydration.
Astaxanthin6mg+ An exceptionally potent antioxidant — 100x more powerful than vitamin E — shown to extend lifespan 12% in animal models and target most hallmarks of aging. Reduces LDL cholesterol, systolic blood pressure, and oxidative damage while increasing your body's own antioxidant defenses. Also improves working memory and protects skin against UV damage.
Zeaxanthin2mg+ A carotenoid that accumulates in the fovea (center of the retina) and works synergistically with lutein for comprehensive eye protection against blue light. Paired with lutein, shown to improve word learning and cognitive function. Both increase BDNF (brain-derived neurotrophic factor), supporting brain health and plasticity.
Glucosamine750mg+ The amino sugar your body uses to build and maintain cartilage, associated with reduced all-cause mortality across cardiovascular, cancer, and respiratory categories. Shown to reduce joint pain, enhance physical function, and decrease markers of collagen breakdown. Also extends lifespan in animal models by mimicking calorie restriction and increasing autophagy.
L-theanine200mg+ Reduces stress and anxiety while improving sleep quality — shown to help you fall asleep faster with better overall sleep architecture. Offsets the negative effects of caffeine on sleep and supports healthy cortisol rhythms. Also improves depression and anxiety scores and reduces blood pressure increases during stress.
Lithium400mcg+ A trace mineral associated with longer lifespan in human populations. Clinically demonstrated to maintain cognitive function and improve mood at just 400mcg daily. At trace doses, increases autophagy in the brain (clearing dysfunctional proteins), improves stem cell function, and may reduce neurodegenerative disease risk.

What you will feel

Complete support
for decades to come.

Sustained energy +
Steady fuel all day without crashes. Creatine and taurine support mitochondrial energy production at the cellular level.
Brain clarity +
Sharper focus, less afternoon fog. Ergothioneine protects brain cells directly where it matters most, lithium supports long-term neuroprotection, and creatine powers cognitive function under stress.
Deeper sleep +
Fall asleep faster, wake rested. L-theanine and glycine improve sleep quality and reduce time to fall asleep.
Gut comfort +
Reduced bloating as balance restores. Inulin feeds beneficial gut bacteria, creating short-chain fatty acids that reduce inflammation.
Heart health +
Support for healthy blood pressure and cholesterol. CoQ10 fuels cardiac muscle cells while taurine helps blood vessels relax and reduces inflammation.
Joint support +
Less stiffness, more comfortable movement. Glucosamine sulfate supports cartilage repair and reduces joint space narrowing over time.
Stronger muscles +
Greater strength, faster recovery. Creatine accelerates muscle gains and improves bone density over time.
Healthier skin +
Better elasticity, natural UV defense. Astaxanthin protects against UV damage while glycine supports collagen production.
Sharper vision +
Macular protection and blue light filtering. Lutein and zeaxanthin accumulate in the retina, reducing age-related vision decline.
Cellular defense +
Long-term protection at the cellular level. Taurine, CoQ10, and astaxanthin target all 12 hallmarks of aging to slow biological decline.

Our Story

Sceptics first,
founders second

The wellness industry is loud, contradictory, and exhausting. One guru swears by this. Another says it's worthless. You're left with a cabinet full of half-used bottles and more questions than answers.

At Coastline, we cut through the noise. Our team of clinical researchers spent years reviewing thousands of studies to identify what actually works. The result? 13 ingredients. Nothing speculative. No fads. No fluff. No filler.

This is what happens when science, not marketing, leads the way.
