A Soothing Herbal Complex of Marshmallow Root, Chamomile & Meadowsweet

Acid Calm is a herbal food supplement for comfortable digestion, taken daily after breakfast or lunch. Mucilage-rich marshmallow root and cooling meadowsweet are blended with calming chamomile, as whole-herb powders in plant-based capsules.

The Herbs

Acid Calm brings together two groups of herbs traditionally used for the upper digestive tract. Soothing, cooling herbs calm gastric heat and protect the stomach lining. A calming herb settles the stress that so often unsettles the stomach. Together they make a blend for comfortable digestion after meals.

To Soothe and Cool

Marshmallow Root (Althaea officinalis): Traditionally used to soothe upper gastric heat and irritation, especially during episodes of excess acidity. Its natural mucilage coats and cools the stomach lining, helping it rest and recover.

Meadowsweet (Filipendula ulmaria): A gentle, cooling digestive herb, traditionally used to balance gastric juices and soothe an over-acid stomach.

To Settle

Chamomile (Matricaria recutita): Traditionally used to relax tight, spasmodic digestive muscles and ease trapped wind and an unsettled stomach, while calming the nervousness that so often accompanies digestive upset.

How to Take: 2 capsules a day with water, ideally after breakfast or lunch.

Safety & Cautions

Do not exceed the recommended daily intake.

Food supplements must not be used as a substitute for a varied, balanced diet and a healthy lifestyle.

Not suitable for use during pregnancy or breastfeeding.

If you are taking any prescribed medication, please consult one of our Medical Herbalists or your healthcare practitioner before use.

Keep out of reach of children. Store in a cool, dry place away from direct sunlight.

An After-Meal Ritual

Eat Smaller Meals: Four or five lighter meals through the day in place of three large ones, eaten slowly and chewed well.

Stay Upright: Two to three hours upright after eating, with the head of the bed slightly raised if night-time discomfort is a problem.

Know the Triggers: A simple food diary to spot what aggravates the stomach, often fried food, hot spices, fizzy drinks, coffee and alcohol.

Sip a Calming Tea: A cup of Zen Maitri Digestion Tea between meals.

Marshmallow root is traditionally taken for indigestion,
acidity and an irritated stomach. It is a demulcent, meaning it is rich in
mucilage — a slippery plant substance that coats and soothes. Acid Calm
combines it with chamomile and meadowsweet.

Brahmi (Bacopa monnieri) is a small creeping marsh plant used in Ayurveda as a medhya rasayana — one of a small group of herbs named specifically for the intellect. It is traditionally taken over months rather than occasionally.

Focus contains no caffeine and no stimulants. It is taken consistently over weeks rather than for an immediate lift, so it works differently from coffee and will not cost you your evening.

Speak to your doctor or one of our Medical Herbalists before combining Acid Calm with any prescribed medicine, including proton pump inhibitors such as omeprazole or lansoprazole. Persistent indigestion should always be looked at by your doctor rather than managed at home.

Take two capsules daily with water, after breakfast or lunch. One bottle contains 60 capsules, a 30-day supply. Leave at least two hours between Acid Calm and other supplements.

Three botanicals and a plant cellulose shell: marshmallow root, chamomile flowers and meadowsweet herb. No fillers, binders, flow agents, magnesium stearate or artificial additives. Vegan and gluten-free.

The capsules are the fullest formula at seven botanicals, adding shankhpushpi. The tincture is faster-acting with six. The tea is a simple four-herb infusion. Many people take the capsules daily and keep the tincture for demanding afternoons.

Many individuals incorporate our Acid Calm Capsules into their wellness routines to naturally manage symptoms of occasional acid indigestion and support a comfortable stomach lining. Ingredients like
Marshmallow Root, Chamomile, and Meadowsweet are valued for their natural ability to coat and soothe the digestive tract.

Many people take Balance in the morning and Deep Sleep at night, as they are formulated for different parts of the day. Both contain ashwagandha, so if you would like to check the combined amount is right for you, speak to one of our Medical Herbalists.

Balance contains no caffeine and no sedative herbs. Ashwagandha, rhodiola and tulsi are taken in the morning in traditional practice, and the formula is designed for daytime use.

Customer photo review of Acid Calm Supplements | For Indigestion and Acid Reflux Relief

Have had stress related acid reflux for many years. Once you have it for 3 years, you have it for life! If you have got this because of a stressful job, leave your job! Have recently discovered these tablets - they really help. Would add I am also on ones from the Dr. and the homeopath - life's a bitch!

Acid Calm has changed my life, I no longer use PPIs and my acid reflux is completely under control every day.

I have found these tablets helpful. They have lessened the problem but they have not cured it.

Acid Calm is amazing, changed my life. Brilliant customer service too. So happy I found this company.

This was my first time trying this, so far so good, wanting to continue to see results in a longer period.
