Benealth’s Deep Sea Three (microcrystalline hydroxyapatite complex) is far more than calcium — it’s the entire bone matrix your body instinctively uses to rebuild and strengthen itself.

Clinically Proven Benefits

Deep Sea Three is shown to be ~40% more bioavailable than supplements made with calcium carbonate or citrate, and uniquely demonstrated to reduce bone resorption (CTX) by up to 30% in six months.

Research also shows greater reversal of bone loss compared to calcium alone, alongside improved joint comfort as natural collagen supports cartilage integrity.

The Science: How Deep Sea Three Works

Hydroxyapatite is the exact mineral structure of human bone.
Unlike isolated calcium, Deep Sea Three integrates directly into bone tissue, giving your body the full blueprint it naturally recognises.

Native collagen forms the flexible scaffold that strengthens bone, tendons, and connective tissue. Most supplements use hydrolysed (broken) collagen — ours is intact, structurally identical to what your body uses in nature.

Vitamin C + D3 + K2 [MK-7]

• Vitamin C: Supports collagen formation, antioxidant protection

• Vitamin D3: Enhances calcium absorption in the gut for improved mineral uptake

• Vitamin K2 (MK-7): Activates osteocalcin (which binds calcium to bone) and MGP (which prevents calcium deposits in arteries)

Essential Trace Minerals

Magnesium, zinc, manganese, and more — natural cofactors in 500+ enzymatic reactions that drive bone remodeling, collagen synthesis, and connective-tissue repair.
