How STOMACH works
Built around the barrier.
Your stomach makes acid strong enough to break down a steak. A layer of mucus over a single sheet of cells keeps that acid off the stomach wall, and your body renews the surface every few days. STOMACH supplies four ingredients chosen for that lining.
-
Supports the gastric lining
Vitamin A, as beta-carotene, supports normal mucous membranes, including the lining of your stomach.
-
Supports collagen formation
Your body needs vitamin C to form collagen. Researchers have studied Centella asiatica for its role in collagen and fibronectin production.
-
A film-forming fiber
Chitosan forms protective films, which is why you find it in medical dressings. STOMACH uses CM chitosan, a water-soluble form.
-
Nothing to decode
All four ingredients are on the label. Two of them share one blend line, and we tell you that up front.
These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.
The formula
Four ingredients that work.
Vitamins A and C carry their own amounts on the Supplement Facts panel. Centella asiatica and CM chitosan share one blend line, so the label does not list their individual amounts.
Centella asiatica extractAlso called gotu kola. A traditional botanical studied for its role in collagen and fibronectin production. 
CM chitosanA water-soluble form of chitosan, the film-forming fiber made from shellfish chitin. 
Vitamin AAs beta-carotene. Supports the maintenance of normal mucous membranes. 
Vitamin CAs ascorbic acid. Needed for normal collagen formation and helps protect cells from oxidative stress.
The routine
One capsule. Twice a day.
No powders and no shakers. One jar holds 60 capsules, a 30-day supply.
-
Morning
Take one capsule with breakfast or a light snack.
-
Evening
Take the second with your evening snack. Same times, every day.

Good questions
Questions, answered.
Start with what is in the jar. Then look at the details that matter to you.
What is LITMUS?
LITMUS is the new name for Alexsyn’s supplements, formulated in the USA. Each product does one job, names every ingredient on the label and tells you what it does not do. STOMACH supports the stomach lining.
What does a stomach lining supplement do?
A stomach lining supplement supplies nutrients that support the normal structure of the barrier between digestive acid and your stomach wall. In STOMACH, vitamin A supports normal mucous membranes and vitamin C supports collagen formation, alongside Centella asiatica and CM chitosan. It is not an antacid and does not treat any digestive condition.
How does the stomach lining protect itself from acid?
The stomach lining, called the gastric mucosa, works in layers. Surface cells coat it with a gel of mucus and bicarbonate that keeps acid off the wall. Tight junctions seal the gaps between those cells. And your body replaces the surface cells every few days, so the barrier is always being rebuilt.
How often does the stomach lining replace itself?
The surface cells of the stomach lining turn over every three to five days in healthy adults. Because that renewal never stops, the nutrients the lining relies on, such as vitamin A for mucous membranes and vitamin C for collagen, matter every day.
How can I support my stomach lining?
Start with the basics: regular meals, less alcohol and no smoking. If you take pain relievers such as ibuprofen often, ask your doctor about it, because they reduce the protective mucus your stomach makes. Nutrition counts too. STOMACH supplies vitamins A and C with Centella asiatica and CM chitosan, one capsule twice a day.
Is STOMACH the same as Amend GI™?
STOMACH uses the same four ingredients as Amend GI™: Centella asiatica extract, CM chitosan, vitamin A as beta-carotene and vitamin C. LITMUS is Alexsyn’s new name, and STOMACH is the new name and label. See the ingredients.
How do I take STOMACH?
Take one capsule twice a day, one in the morning and one in the evening, with a light snack. Each jar holds 60 capsules, a 30-day supply.
How much does STOMACH cost?
A single jar is $39.95. Subscribe and it is $33.96 a jar delivered monthly (save 15%), or $95.88 for three jars every 90 days, which works out at $31.96 a jar (save 20%). Skip or cancel a subscription anytime.
What is the money-back guarantee?
100% money-back. Email info@takelitmus.com within 45 days of purchase and the refund goes back to your original payment method. Read the terms.
Is STOMACH vegan?
No. CM chitosan is derived from shellfish, so STOMACH is not suitable for a vegan diet.
