Complete Upgrade.
Day and Night.
Comprehensive support that's easy to stick with.
Step 01 — Morning
Morning Blend + Softgels
With breakfast · 10 ingredients
Morning Blend
A precision-dosed powder with the building blocks your cells need most. Mix with water at breakfast for sustained energy, sharper focus, and metabolic support throughout the day.
The most studied performance compound in sports science. Creatine buffers ATP levels in your muscles and brain, acting as a cellular energy reserve. Supports cognitive function under stress and helps maintain muscle strength as you age.
A key amino acid your body uses to build collagen, produce glutathione (your master antioxidant), and support healthy sleep cycles. Research shows glycine helps maintain cellular repair processes and may promote healthy aging at the metabolic level.
A prebiotic fiber that feeds the beneficial bacteria in your gut. At the clinical dose of 4g, inulin supports digestive regularity, nutrient absorption, and a healthy gut microbiome — the foundation of immune function and overall wellbeing.
The most abundant amino acid in your cells — and levels drop significantly with age. Taurine supports mitochondrial function, cardiovascular health, and endurance. A landmark 2023 study in Science linked taurine supplementation to healthier aging across multiple body systems.
Involved in over 300 enzymatic reactions in your body, yet most adults are deficient. Magnesium supports muscle and nerve function, energy production, and cardiovascular health. It also plays a critical role in sleep quality and stress regulation.
A powerful antioxidant your body actively transports to the cells that need it most — brain, liver, kidneys, and eyes. Often called the "longevity vitamin," ergothioneine protects against oxidative damage and supports cognitive health as you age.
Softgels
Four fat-soluble antioxidants taken with breakfast for optimal absorption. They support your mitochondria, protect your vision, and defend against oxidative stress at the cellular level.
Essential for mitochondrial ATP production — the energy currency of every cell. Your body makes less CoQ10 after age 30. Supports heart function, reduces fatigue, and protects cells from oxidative stress.
A carotenoid that concentrates in your retina and brain. Lutein filters harmful blue light, protects your vision from age-related decline, and supports cognitive processing speed. Your body can't produce it — it must come from your diet.
One of nature's most powerful antioxidants — up to 6,000 times stronger than vitamin C. Derived from microalgae, astaxanthin crosses the blood-brain barrier to protect your brain and eyes. Also supports skin elasticity and exercise recovery.
Works alongside lutein to form your eye's natural UV shield. Zeaxanthin concentrates in the center of your retina (the macula), where it protects against blue light damage and supports sharp central vision as you age.
Step 02 — Evening
Evening Capsules
Before bed · 3 ingredients
Capsules
Three targeted compounds timed for your body's overnight repair cycle. They support deep sleep, calm the nervous system, and maintain joint health while you rest.
A natural compound your body uses to build and repair cartilage. Glucosamine supports joint cushioning, flexibility, and comfort — especially important as cartilage production slows with age. Timed for evening when your body's repair processes are most active.
An amino acid found naturally in green tea that promotes calm without drowsiness. L-theanine increases alpha brain wave activity, helping you unwind and transition into restful sleep. Also supports focus and stress resilience during the day.
At micro-dose levels (400mcg — far below therapeutic doses), lithium orotate supports neuroprotection and mood stability. Research links trace lithium intake to brain health and emotional resilience. A subtle but powerful addition to your evening routine.

Start My System — $99/mo“The nutrients your body needs most are the ones it's losing.”
After 35, things start to shift. Taurine declines. Creatine drops. CoQ10 production slows. Your cells' DNA accumulates damage. Cellular defenses weaken. Strength fades. It happens gradually, invisibly — and faster than you can replace through food alone. These aren't fringe compounds — they're the building blocks your cells depend on every day.
And the supplement industry? It makes the problem worse. Mystery ingredients that hide what's inside. "Pixie-dusted" formulas with 90 ingredients at trace amounts. Loud marketing, quiet science.
There's a better way.

What It Does
5 benefits you'll feel — from week one.
Every ingredient earns its place. Here's how they work together — morning and evening — to keep you sharp, strong, and resilient.
Click to scroll to a benefit ↓
Sustained energy
without the crash.
Real energy comes from your mitochondria — the powerhouses inside every cell. Coastline supports energy at its source, not with stimulants that leave you depleted by 3pm.
Stay sharp through work and play. Whether it's a board meeting or a backyard game of catch, you've got the fuel to show up fully.
Key Ingredients
Essential for mitochondrial ATP production. CoQ10 shuttles electrons in the energy chain inside your cells — and your body makes less of it after 30.
May support heart function and reduce fatigue. Also studied for migraine frequency.
Buffers ATP levels in muscles and brain. Think of it as your cellular energy reserve — for physical and mental performance.
May support cognitive function under stress and help maintain muscle strength as you age.
The most abundant amino acid in your cells — and levels drop significantly with age. Supports mitochondrial function and endurance.
May support cardiovascular health and healthy metabolism.
Bounce back
like you used to.
Whether it's weekend basketball, a morning run, or chasing your kids around the yard — your body needs to recover as hard as it works.
Creatine builds strength. Magnesium reduces soreness. Taurine supports endurance. Together, they help you stay active without paying for it the next day.
Key Ingredients
Consistently shown to increase muscle strength and power. Also supports bone mineral density in older adults during training.
Cofactor for 300+ enzymes. Reduces muscle soreness and speeds recovery from exercise. About half of adults don't get enough.
Enhances endurance performance, especially in heat. Supports cardiovascular function and reduces inflammatory markers.
Your evening routine,
optimized.
Better sleep doesn't start when your head hits the pillow. It starts with what you give your body in the hours before. Our evening capsules support your natural wind-down.
Better sleep means better mornings. Better mornings mean a better you. It's a simple chain — and it starts here.
Key Ingredients
Found naturally in tea. Reduces stress and anxiety, improves sleep quality, and helps you fall asleep faster. No grogginess the next morning.
A trace mineral at ~1/100th of prescription doses. Supports cognitive function and mood at levels found naturally in tap water.
Acts as a chronobiotic — helps regulate your circadian rhythm for better sleep-wake cycles.
An amino acid that improves sleep quality and reduces daytime sleepiness. Also a precursor for glutathione — your body's master antioxidant.
Gut health, heart health,
and everything between.
A healthy gut is the foundation. Coastline includes Inulin — a prebiotic fiber that feeds beneficial bacteria, strengthens your gut lining, and improves nutrient absorption. From there, Taurine, CoQ10, and Magnesium support the numbers your doctor watches: blood pressure, cholesterol, and blood sugar.
When your gut and heart are working right, everything else follows.
Key Ingredients
Prebiotic fiber that supports growth of healthy gut bacteria (Bifidobacteria). Strengthens gut lining, increases calcium uptake, and reduces LDL cholesterol and triglycerides.
Also enhances magnesium absorption — working together with the magnesium in your morning blend.
Reduces both systolic and diastolic blood pressure. Lowers LDL cholesterol and triglycerides. Improves fasting insulin and blood sugar control.
Extended lifespan 10-12% in mice by targeting nearly all hallmarks of aging.
Reduces hospitalizations and mortality in heart failure. Essential for mitochondrial energy production — and your body makes less after 30.
Also offsets the CoQ10 depletion caused by statin medications.
Higher intake associated with 6% reduced all-cause mortality per 100mg/day. Reduces blood pressure, improves blood sugar, and supports insulin sensitivity.
Over 50% of adults don't meet the recommended daily amount.
Defend your brain, eyes,
skin, and cells — long term.
The sharpness you rely on today needs protecting for tomorrow. Coastline delivers compounds that cross the blood-brain barrier, shield your eyes from blue light damage, support skin elasticity and hydration, and defend your cells against oxidative stress.
Think of it as insurance for the things you can't replace. Your cognitive edge. Your vision. Your skin. Your cellular health. Supported every single day.
Key Ingredients
Crosses the blood-brain barrier and accumulates in the brain. Boosts NAD+ levels. Improves cognitive function and memory in clinical trials.
Protects mitochondrial DNA from damage — one of the most promising longevity compounds in current research.
Accumulate in the macula of your eye to filter blue light and protect against age-related vision decline. Lutein also concentrates in the hippocampus — supporting memory and learning.
Most adults only get 1-2mg/day. Coastline delivers the clinical dose from the AREDS2 study.
Over 100x more potent than vitamin E as an antioxidant. Extended lifespan 12% in mice. Improves working memory and reaction time.
Accumulates in cell membranes and mitochondria — protecting your cells from the inside out.

Our Story
“Skeptics first.
Founders second.”
We didn't start Coastline because we believed in supplements. We started because we didn't. Every product we tried was either underdosed, overhyped, or hiding behind a label designed to confuse.
So four of us — dads, researchers, skeptics — built the thing we couldn't find. Thirteen ingredients. Every dose matched to the clinical trial, not the marketing budget. Timed to your biology. Simple enough to actually stick with.
No fads. Nothing speculative. Just the science — and the stubbornness to get it right.

Co-Founder, Coastline Longevity
