- What we use

Red algae
Aquamin®, harvested off Iceland. Calcium, magnesium, and trace minerals. And our D3 is from algae too.
930mg of calcium and 68mg of magnesium from Aquamin® Icelandic red algae, 80mcg of K2 as MK-7 from natto, 25mcg of VegD3® from algae, and 25mg of an organic veggie and fruits blend. Vegan, non-GMO, gluten free. Three slim tablets a day. Supports bone strength and density.†
From the ranch
Calcium. From the sea, not the quarry.

Three tablets. All the benefits.
Bone strength
930mg calcium from Aquamin® Icelandic red algae — a whole mineral complex, not ground rock.†
Heart & arteries
80mcg K2 as MK-7 helps direct calcium to bones, not arteries.
Immune support
25mcg VegD3® from algae — the same D3 form, without the sheep’s wool grease.
Daily minerals
72 trace minerals including magnesium and strontium, already present in the algae.
Clean label
Vegan, non-GMO, gluten free. No dairy, shellfish, soy, or animal ingredients.
This is for you if:
You’re vegan and still want real calcium.
The calcium is algae, and the D3 is VegD3® from algae rather than sheep wool grease. That’s what makes the bottle qualify.
You want a source you can look up.
Aquamin® is a named marine mineral complex from Marigot Limited, harvested off Iceland — not unlabeled “calcium carbonate.”
You want the cofactors included.
Magnesium, 72 trace minerals, K2 as MK-7, and D3 come in the same tablet instead of three more bottles.
You’ll take three slim tablets a day.
They’re built narrow on purpose, and once a day with food is the whole routine.
This may not be for you if:
You won’t take three tablets a day.
Three is three. If you won’t do it, buy something you will actually take.
You’re on blood thinners.
Vitamin K2 is worth a conversation with your doctor before you start.
You want the cheapest calcium per milligram.
That’s carbonate, and it’s four dollars at any pharmacy. Algae costs more to source and we won’t pretend otherwise.
You want a fast result.
This supports bone health over time. Nothing about bone density moves in a month.

Red algae vs. the calcium in the drugstore aisle.

What’s in the bottle
Anatomy of a tablet.
Aquamin® red algae
930mg of calcium and 68mg of magnesium from mineralized Lithothamnion harvested in Icelandic waters, with 72 additional trace minerals including strontium and vanadium.
Vitamin K-2 (MK-7)
80mcg of menaquinone-7, the longer-acting form, sourced from fermented soybeans.
VegD3® vitamin D3
25mcg of cholecalciferol from organic algae instead of lanolin. It’s the reason this bottle is vegan.
Organic veggie & fruits blend
25mg of organic broccoli sprouts, carrot, kale, spinach, tomato, broccoli, strawberry, raspberry, wild blueberry, tart cherry, cranberry, and pomegranate.
Together: 930mg calcium per serving of three slim tablets, 30 servings per bottle. Supports bone strength and density.†
How to use
Three slim tablets. Once a day.
Pour whatever you drink in the morning — water, coffee, juice. Take three slim tablets, easiest with food. Same time daily. Bone density rewards the boring version.

Three slim tablets daily, or as directed by a healthcare professional. Store cool and dry, away from direct light.
Why algae instead of limestone, shell, or bone?
Walk the calcium aisle and most of what’s there is calcium carbonate — ground limestone, oyster shell, or in some cases bone meal. It’s cheap, it works, and almost no label tells you which one you’re holding.
Aquamin® is different in kind, not just in marketing. It’s a mineralized red algae (Lithothamnion) collected off Iceland, and because it’s a whole mineral complex it arrives with magnesium and dozens of trace minerals already in it rather than isolated and recombined.
The vitamin D is the part most people don’t know about: standard D3 is made from lanolin, which is wool grease. If a calcium supplement says “vegan,” the D3 is the reason it can. Ours is VegD3®, from algae.
Trade-off, stated honestly: it’s three tablets daily, not one. And algae calcium costs more to source than ground limestone, which is why this bottle is priced above the drugstore shelf. If cost per milligram is your only measure, carbonate wins and we won’t pretend otherwise.
