Organic Lithothamnion – marine calcium and magnesium, vitamins D3 and K2
Your body draws on its calcium reserves every day but can never replenish them on its own. Lithothamnion answers that need with calcium from a seaweed.
Lithothamnion (Lithothamnium calcareum) is a calcareous red seaweed that, as it grows on the ocean floor, naturally concentrates calcium and magnesium in its porous skeleton. Our Organic Lithothamnion is harvested at a depth of 18 metres off the coast of Maranhão, Brazil, then combined with plant-derived vitamins D3 and K2, the duo that anchors calcium in bone. Two capsules provide 83% of the NRV for calcium. Organic, 100% natural, in plant-based capsules. Algorigin is a Swiss brand: Lithothamnion is available in more than 600 Swiss pharmacies.
Strong bones over time: calcium is needed for the maintenance of normal bones, and vitamin D contributes to its normal absorption.
The duo that anchors calcium: vitamin D contributes to the normal absorption of calcium, and vitamin K contributes to the maintenance of normal bones.
Digestion and acidity: calcium contributes to the normal function of digestive enzymes; Lithothamnion is traditionally used for its buffering effect on stomach acidity.
“As a PhD in biology, I recommend a 3-month course: just the right length of time to build deep, lasting results, with complete confidence.”

What is Lithothamnion?
Lithothamnion (Lithothamnium calcareum, also known as maerl) is a small red seaweed from the seabed that fixes calcium and magnesium from seawater in a porous calcareous structure, like a plant coral. Harvested, dried and ground into powder, it provides natural marine calcium together with magnesium and around thirty trace elements (silicon, iron, iodine in trace amounts).
Lithothamnion has been used for decades in herbal medicine for two purposes: remineralisation (bones, joints, menopause) and digestive comfort, thanks to its alkalising power, which buffers stomach acidity (acid reflux, heartburn). Our formula adds plant-derived vitamins D3 and K2, needed for calcium to be absorbed and then directed to the bones. For your heart and brain, discover our vegan omega-3 too
What are the benefits of Lithothamnion?
Bones
Calcium is needed for the maintenance of normal bones and teeth. Vitamin D contributes to normal absorption/utilisation of calcium and phosphorus and to the maintenance of normal bones. Vitamin K contributes to the maintenance of normal bones. Magnesium contributes to the maintenance of normal bones.
Lithothamnion and the stomach: acidity, reflux, heartburn
Lithothamnion is traditionally used as a natural antacid: its calcium carbonate buffers excess stomach acid. Calcium contributes to the normal function of digestive enzymes. Our customers take it with meals for comfort after big meals. See the Digestion Pack.
Muscles, tiredness, nerves
Magnesium contributes to normal energy-yielding metabolism, to the reduction of tiredness and fatigue, to normal muscle function and to the normal functioning of the nervous system. Calcium contributes to normal muscle function.
Menopause
After 50, calcium and vitamin D needs increase. Lithothamnion is the foundation of our Menopause Pack.
Lithothamnion and sleep
Magnesium contributes to the normal functioning of the nervous system and to normal psychological function. Taken with your evening meal, Lithothamnion provides magnesium and calcium.
Growth
Vitamin D is needed for normal growth and development of bone in children (adjusted dosage).
Who is it for?
Over 50 and during the menopause
To maintain bone health over the long term, with the D3 + K2 duo.
For stomach acidity and reflux
As a natural antacid, taken with meals, aluminium-free.
Vegetarians, vegans and people who avoid dairy
A 100% plant-based, lactose-free source of calcium. The vitamin D3 comes from lichen, the K2 from plant fermentation.

They take and recommend our Lithothamnion
Real comfort
I feel much lighter after meals since I started taking Lithothamnion. And I'm so glad to have found a natural option, an alga rather than a synthetic molecule. I feel much better day to day.
A good everyday product
I've been taking Lithothamnion for a few weeks, two capsules with meals. I definitely feel more comfortable after big meals. It's a good natural product and I plan to keep going for a few more months.
A good mealtime habit
Two capsules with meals has become second nature, and I feel good with this routine. I also know that calcium is needed for the maintenance of normal bones, so I'm playing the long game. A natural product I recommend.
Part of my daily routine
I've been taking it with every meal for two months and I feel more comfortable day to day. I like the ingredients: a seaweed harvested at sea, minerals, vitamins D3 and K2, nothing else. I'm very satisfied.
Organic Lithothamnion: an excellent food supplement
Lithothamnion's formula is very well suited to older people: calcium, magnesium and vitamins D3 and K2, carried by an alga. My 81-year-old mother takes it all year round and it suits her perfectly. Thank you
Laboratory testing
Purity isn't something you claim, it's something you verify. We have both our raw materials and our finished products laboratory-tested for purity and active compound content, and we publish the results.
Strong bones over time
Calcium is needed for the maintenance of normal bones, and vitamin D contributes to its normal absorption.
The duo that anchors calcium
Vitamin D contributes to the normal absorption of calcium, and vitamin K contributes to the maintenance of normal bones.
Digestion and acidity
Calcium contributes to the normal function of digestive enzymes; Lithothamnion is traditionally used for its buffering effect on stomach acidity.
Dosage: how should I take Lithothamnion?
Take 2 Lithothamnion capsules a day, with a meal and a glass of water. A single dose of 1 capsule is also possible. A jar lasts 25 days.
When should I take Lithothamnion: before or after a meal?
With a meal, for calcium absorption and its buffering effect on acidity. If you suffer from night-time reflux, with dinner.
How long does a course of Lithothamnion last?
3 months for remineralisation, renewable; all year round for digestive comfort, as a maintenance habit.
Lithothamnion and sleep: in the evening?
Yes, taking it with dinner is perfectly fine (magnesium).
Precautions
If you take anticoagulants (vitamin K), consult a doctor before use. If you take levothyroxine, leave 4 hours between doses (calcium reduces the absorption of thyroid hormone). Do not combine with another calcium supplement without medical advice. Lithothamnion contains trace amounts of iodine: if you have a thyroid condition, seek medical advice.

Frequently asked questions about Lithothamnion
What are the benefits of Lithothamnion?
Lithothamnion provides marine calcium (needed for the maintenance of normal bones) and magnesium (reduction of tiredness and fatigue, muscle function). It is traditionally used as a natural stomach antacid. Our formula adds vitamins D3 and K2, which contribute to the maintenance of normal bones.
Is Lithothamnion effective against heartburn and reflux?
Lithothamnion is a natural antacid: its calcium buffers stomach acid. Taken with meals, it is traditionally used for acid reflux and heartburn. If reflux persists, see your doctor.
Is Lithothamnion dangerous? Does it have side effects?
At the recommended doses, it is well tolerated. Too much calcium can cause constipation: stick to 2 capsules a day and drink enough water. If you take anticoagulants (vitamin K) or levothyroxine, or have a thyroid or kidney condition (stones), seek medical advice.
Lithothamnion and levothyroxine: can they be combined?
Yes, taking them 4 hours apart: calcium reduces the absorption of thyroid hormone.
How long should I take Lithothamnion?
3 months for remineralisation, all year round for digestive comfort.
When should I take Lithothamnion, before or after a meal?
With a meal. In the evening with dinner if you suffer from night-time reflux, or for the magnesium.
Lithothamnion or conventional calcium: what is the difference?
Lithothamnion provides natural marine calcium together with magnesium and trace elements, in an organic seaweed; standard supplements are isolated calcium salts. Our formula adds the D3 and K2 needed for calcium absorption and uptake into bone.
Is Lithothamnion suitable for vegans?
Yes: alga, plant-based capsule, vitamin D3 from lichen and plant-based K2.
Does Lithothamnion contain iodine?
In trace amounts, like any seaweed. If you have a thyroid condition, ask for advice.
Powder or capsules?
Lithothamnion powder (often sold for gardening) has a chalky taste and is measured out by the spoonful. Algorigin capsules deliver a precise dose, with D3 and K2, and no taste.
