Expert Opinions
"The 13 ingredients of Coastline I consider to be foundational to the future of human health."
"After reviewing thousands of research papers and analyzing countless supplement protocols, these 13 ingredients represent the gold standard. Each one has robust clinical evidence and addresses fundamental aspects of healthy aging that I see compromised in my practice every day."

Sleep & Circadian Health Researcher
"Coastline is what happens when you combine scientific rigor with real-world clinical understanding."
"After over two decades working in the clinical nutrition industry, I’ve seen how confusing the supplement landscape can be — even for health professionals. Coastline takes a refreshingly disciplined approach: evidence-driven ingredients, clinically meaningful doses, and clear intent behind every inclusion.
It’s a formulation built not to follow trends, but to stand the test of time — one that truly supports the biology of aging from the inside out."
– Dr. Jacqueline Jacques, ND
Doctor of Naturopathic Medicine
Wellness Industry Expert
"I value Coastline's quality, scientifically rigorous ingredients. It eliminates hassle with the greatest certainty of results."
"When I'm looking at a supplement, I'm considering two primary factors – one, is it noticeably effective as determined by, primarily, human trials, and two, is it dosed appropriately. Coastline does both to the fullest degree. Additionally, it does this in one simple supplement matrix that hits all aspects of healthspan, and with a certainty in quality."

"Coastline represents a new era of precision supplementation — one rooted in clarity, science, and consistency."
"Most supplements are built around marketing stories rather than measurable outcomes. What Coastline has done is strip away that noise and focus only on ingredients with real mechanistic data behind them — compounds that directly influence the pathways of cellular health, recovery, and longevity.
For me, that’s the future: fewer ingredients, more certainty, and an evidence-based foundation people can trust every single day."
– Dr. Chris Pollock, PhD
"Developed after a thorough evaluation of the latest advances in health sciences, Coastline represents the state of the art In longevity science."
"Coastline bridges cutting-edge aging research with practical human health. Its ingredients aren’t speculative — they’re backed by strong mechanistic evidence supporting cellular resilience and healthy aging. It’s a rare formulation that truly reflects where longevity science stands today."

Morning Blend Ingredients
Creatine Monohydrate - 5250 mg
The gold standard form for cellular energy metabolism and cognitive function. Supports muscle strength, power output, and brain health while helping maintain ATP production - your body's primary energy currency. Research shows it may help preserve muscle mass and cognitive performance as you age, making everyday activities feel easier and supporting mental clarity throughout your day.
L-Glycine 5000 mg
A foundational amino acid that's crucial for collagen synthesis, supporting healthy skin, joints, and connective tissues. Acts as a calming neurotransmitter that can improve sleep quality while supporting detoxification processes in the liver. As glycine production declines with age, supplementation helps maintain tissue repair, wound healing, and may support longevity pathways.
Inulin (from Chicory) 4000 mg
A premium prebiotic fiber that selectively feeds beneficial gut bacteria, supporting digestive health and immune function. Helps improve mineral absorption, particularly calcium and magnesium, while promoting regular bowel movements. A healthy gut microbiome is linked to better mood, immune response, and even cognitive function - making this a foundation for overall wellness.
Taurine 3050 mg
An essential amino acid that declines significantly with age, supporting cardiovascular health, exercise performance, and cellular protection. Helps regulate electrolyte balance, supports healthy blood pressure, and may improve insulin sensitivity. Research suggests taurine supplementation can help maintain youthful cellular function and energy levels as you age.
Glucosamine 750 mg
A building block compound essential for healthy cartilage and joint function. Helps maintain joint mobility, reduces stiffness, and supports the body's natural ability to repair and maintain connective tissues. Particularly important as natural glucosamine production decreases with age, leading to joint discomfort and reduced mobility over time.
Magnesium Citrate 150 mg
An essential mineral cofactor in over 300 enzymatic reactions, supporting energy production, muscle function, and nervous system health. Helps regulate blood sugar, supports bone health, and promotes restful sleep. Most people don't get enough magnesium from diet alone, making supplementation crucial for optimal cellular function and stress management.
L-Ergothioneine 5mg
A powerful 'longevity vitamin' and master antioxidant that accumulates in tissues throughout the body, particularly the brain, heart, and liver. Provides cellular protection against oxidative stress and inflammation while supporting mitochondrial health. Research suggests it may help maintain cognitive function and support healthy aging at the cellular level.
Morning SoftGel Ingredients
Coenzyme Q10 200 mg
An essential cofactor for mitochondrial energy production, supporting heart health and cellular energy metabolism. Acts as a powerful antioxidant protecting cells from oxidative damage while supporting cardiovascular function. CoQ10 levels naturally decline with age, making supplementation important for maintaining energy levels, exercise performance, and long-term heart health.
Lutein 10 mg
A carotenoid antioxidant that selectively accumulates in the retina, providing protection against blue light damage and supporting long-term eye health. Helps maintain visual acuity, reduces eye strain from screen time, and may support cognitive function. As natural lutein leve
Zeaxanthin 2 mg
Works synergistically with lutein to form the macular pigment, providing enhanced protection for the central retina and supporting sharp, clear vision. Helps filter harmful blue light, reduces glare sensitivity, and supports overall eye comfort during daily activities. Essential for maintaining long-term eye health and visual performance as you age.
Astaxanthin 6 mg
One of nature's most potent antioxidants, providing comprehensive cellular protection and supporting skin health, eye health, and exercise recovery. Helps reduce inflammation, supports cardiovascular health, and may improve skin elasticity and hydration. Research shows it can help reduce exercise-induced fatigue and support overall vitality and healthy aging.
Evening Capsules
Glucosamine Sulphate 750 mg
Supports joint health and cartilage repair during overnight recovery when your body naturally rebuilds and repairs tissues. Helps maintain joint flexibility, reduces morning stiffness, and supports the body's natural healing processes. Taking it in the evening aligns with your body's natural repair cycle for optimal joint support and long-term mobility.
Lithium 400 mcg
A trace mineral that supports brain health, mood stability, and cognitive function at safe nutritional doses. May help protect neurons, support healthy brain aging, and promote emotional balance. Research suggests it can support longevity pathways and help maintain cognitive clarity and mental resilience as you age, making it an important component of brain health optimization.
L-Theanine 200 mg
An amino acid from tea that promotes calm, focused relaxation without drowsiness while supporting better sleep quality. Helps reduce stress and anxiety, promotes alpha brain wave activity associated with relaxed alertness, and can improve sleep onset and quality. Perfect for evening use to help you unwind and prepare for restorative sleep.
