Healthspan is the length of time you live with vitality, clarity, and independence — not just lifespan. Coastline is built to support the systems that decline with age: energy metabolism, mood, sleep, inflammation, joints, skin, and cognition. The goal isn’t just to live longer — it’s to live better.

All ingredients are used at levels shown to be safe and effective in human studies. All products are third-party tested for purity and potency.

Most people feel improvements in sleep, focus, and energy within the first 1–2 weeks. Deeper benefits — like joint support, skin resilience, and gut health — build gradually with consistent daily use. Think long-term investment, not overnight fix.

No problem. Longevity is about consistency, not perfection. Just resume your regular routine the next day — your body will thank you over time.

Yes — all Coastline Longevity products are 100% vegan, non-GMO, and free from major allergens like gluten, soy, and dairy. Even ingredients like glucosamine, which are often sourced from shellfish, are vegan-certified in our formulas.

Your body follows a circadian rhythm, and our formulas are designed to align with it. We include energizing ingredients like creatine and magnesium in the Morning Blend, and calming, recovery-oriented ingredients like L-theanine and lithium orotate in the Evening Capsules to help your body perform and recover optimally.

While our ingredients are generally safe and well-tolerated, we recommend consulting your healthcare provider if you’re on medication or taking other supplements with overlapping ingredients (like magnesium, glycine, or lithium). Always best to double-check.

Yes — Coastline is designed for all adults looking to support their healthspan. Most users are 30+, but anyone focused on long-term vitality can benefit from our system. It’s safe and effective for both men and women.

If you are pregnant, nursing, or planning to be, please consult your doctor before taking Coastline. While our ingredients are generally safe, this is an important step with any supplement.

Inulin is a prebiotic fiber that supports gut health — but for some people, it can temporarily cause bloating or gassiness, especially if your diet is low in fiber. This usually fades as your gut adjusts. If you’re sensitive, start with a half scoop of the Morning Blend for a few days and build up gradually.

It’s simple:
- Morning: 1 scoop of Morning Blend powder, mixed with water + 1 softgel.
- Evening: 2 capsules with or after dinner.
That’s it — 1 scoop + 3 pills a day for full coverage.

You don’t have to, but many people find it more comfortable on a full stomach. Feel free to mix it with your morning smoothie or drink it on its own after breakfast.

Yes, absolutely. With Coastline you can adjust the frequency of delivery (1-3 months) and/or cancel anytime.
