OUR STORY

Game, set, Benealth.

"We're passionate tennis players. One season, Winter began feeling a persistent knee ache that made play uncomfortable. Looking for answers, we dove into the science of bone and joint health, and found that most supplements were missing the essentials. Everything existed in pieces, but never in the right ratios, never in one complete formula. So we created it. And we're taking it ourselves, every day. Deep Sea Three is part of Winter's daily routine."

— Winter, Founder, Benealth

Make it a morning ritual.

Strong bones aren't built in a day. They're built every day. Here's how to make Deep Sea Three a habit that sticks.

Morning ritual: a bowl of oats with berries and nuts, coffee and orange juice

  • 1. Pair it

    Keep the bottle next to something you already do every morning: the kettle, your coffee, your toothbrush. Same place, same time.

  • 2. Take it

    Take 2-3 capsules daily with a glass of water or your morning coffee/ tea, ideally with food. That's it.

  • 3. Keep the streak

    Tick off each day and share your ritual with #benealth. Small, steady habits add up.

Do not exceed the recommended daily dose.

How it fits into your life.

  • Keep doing what you love

    Calcium, phosphorus and vitamin D3 help maintain normal, healthy bones: the frame behind every serve, stride and school run.

  • Move with ease

    Type I collagen supports the cartilage, tendons and connective tissue that keep you moving.

  • Skin that feels healthy

    Collagen plus vitamin C, which supports natural collagen formation, for skin firmness and elasticity.

  • Smile with confidence

    Calcium and phosphorus are building blocks of healthy teeth.

Microcrystalline form, designed for bioavailability and gentle on the stomach.

More than calcium.

  • What's inside

    A microcrystalline hydroxyapatite complex: calcium and phosphorus in a natural ~2:1 ratio, Type I collagen and trace minerals, plus vitamins C, D3 and K2 (MK-7).

  • Why it works

    Bone needs a framework (collagen) and minerals (calcium + phosphorus). Many calcium supplements only supply one mineral without the framework; Deep Sea Three brings all essentials together for building bones, with the vitamins that support their utilization.

  • Where it's from

    New Zealand's cold, oxygen-rich waters, with marine ingredients sourced under MSC certification.

Questions, answered.

What is Deep Sea Three?

Deep Sea Three is a food supplement made from microcrystalline hydroxyapatite, a marine complex from New Zealand that naturally contains calcium, phosphorus and Type I collagen, with added vitamins C, D3 and K2 (MK-7). It supports bone strength, joint mobility and healthy teeth.

How is it different from a regular calcium supplement?

Most calcium supplements contain only calcium carbonate or citrate. Deep Sea Three supplies calcium and phosphorus in hydroxyapatite (the mineral structure found in bone), plus collagen, vitamins and trace minerals, so the body gets the whole set of bone-building materials together.

What's in each capsule, and how do I take it?

Each 600 mg capsule provides 150 mg calcium, 77 mg phosphorus, 150 mg protein (including 86 mg collagen), plus vitamins C, D3 and K2 and natural trace minerals. See the full nutrition table on the product page. Daily dose: Adults: 2 capsules daily with food. Children 8+ and teens: 1. Perimenopause, postmenopause and adults 50+: 3. See the Deep Sea Three page for the full guide. Most people find it easiest to make it part of their morning routine.
