“You don't notice it at first. Then one day you can't keep up.”
After 35, things start to shift. Taurine levels drop. CoQ10 production slows. Magnesium depletes faster than you can replace it 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. Proprietary blends 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
Five ways Coastline supports your body.
Every ingredient earns its place. Here's how they work together — morning and evening — to keep you sharp, strong, and resilient.
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 dad. 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.

11 body systems.
13 ingredients.
Most supplements target one thing. Coastline supports your entire body — brain, heart, muscles, joints, gut, eyes, skin, immunity, and more. Every system that keeps you going.
Not 11 separate bottles. One system, clinically dosed, covering the full picture — because aging doesn't pick favorites.
Be here for the moments
that matter.
Graduations. Weddings. Grandkids. The moments worth living for are still ahead of you. Coastline supports the systems that keep you going for decades — heart, brain, eyes, and cells.
This isn't about adding years to your life. It's about adding life to your years — and being there for the people who need you most.
Key Ingredients
One of nature's most potent antioxidants — over 100x more powerful than vitamin E. Sourced from microalgae. Supports heart, brain, and skin health.
Accumulate in the macula of your eye to filter blue light and protect against age-related vision decline. Also support cognitive function — lutein concentrates in the hippocampus.
Crosses the blood-brain barrier. Boosts NAD+ levels. Protects mitochondrial DNA from damage. One of the most promising longevity compounds in current research.

Our Story
“Built by researchers, not marketers.”
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.
As Dads ourselves, we built what we couldn't find — a system backed by clinical research, dosed correctly, timed to your biology, and simple enough to actually stick with. No fads. No filler. Just the 13 most evidence-led compounds for longevity.
This is what happens when science, not marketing, leads the way.

AG1 is a greens powder with 75 ingredients at undisclosed doses. Coastline is a precision system with 13 ingredients, each at clinical trial doses, timed to your circadian rhythm. We show every milligram on the label. Most greens powders use proprietary blends that hide what's inside.
Yes, but you likely won't need to. Coastline includes 5.25g of creatine monohydrate — a clinical dose that matches what most people supplement separately. You can replace your standalone creatine with Coastline and simplify your routine.
No. Coastline is 100% caffeine-free. We support energy at the cellular level — through mitochondrial function, not stimulants. No jitters, no crashes, and it won't interfere with your sleep.
Many people notice improvements in energy and clarity within the first few weeks. The full benefits build over time as ingredients reach optimal levels in your body. We recommend 60 days — which is exactly why our guarantee covers that period.
