Andrews Original Salts are a remedy that has been used for over a hundred years. It comes as an effervescent powder that aims to be a fast and effective relief for an upset stomach including symptoms of indigestion. The medicine contains magnesium sulfate, sodium bicarbonate and sodium saccharin. Together they aim to safely control the level and strength of stomach acid to help resolve an upset stomach. The powder dissolves quickly in water and is easy to take at home, work or on the go.

Doctor’s advice

Who is Andrews Original Salts for?

This is best described as treating the symptoms of over-indulgence. More specifically, Andrews is recommended as an antacid for the relief of indigestion. It is suitable for adults and children over the age of 12, making it an option for almost all ages.

How does Andrews Original Salts work?

Andrews Original Salts contain three key ingredients: Sodium bicarbonate, sodium saccharin, and magnesium sulfate.

Sodium bicarbonate works as an antacid in the stomach by neutralizing acidity. Sodium saccharin and sodium bicarbonate in combination also relieve discomfort caused by acidity in the stomach. Magnesium sulfate works in the gut by triggering secretions that favor an accumulation of water and electrolytes in the gut, helping relieve constipation.

Should anyone avoid taking Andrews Original Salts?

Patients with intolerances or allergies to any of the ingredients should avoid taking Andrews salts. This includes people with high blood pressure and heart or kidney issues.

Because of the sugar content, diabetics should also use it with caution. If a laxative is required every day for any longer than 2 weeks, or if there is persistent abdominal pain, then you should consult your doctor for advice.

Are there any side effects?

The main side effect of the medication is diarrhea, which may occur with extensive usage. Inappropriate frequent or prolonged use in people with severe kidney dysfunction may lead to high magnesium or calcium in the blood, which can also cause serious problems.

Occasionally, some people experience a severe allergic reaction to the medication. If you experience any mouth swelling, airway swelling, or shortness of breath, you should treat this as an emergency and dial 911 for emergency services.

Alternatives to Andrews Original Salts

Andrew’s Original Salts is a popular remedy for digestive discomfort, particularly issues such as indigestion, heartburn, and bloating. However, several alternatives can offer similar relief. These alternatives range from over-the-counter antacids to natural remedies, depending on your preference and needs.

1. Milk of Magnesia

Milk of Magnesia is a well-known antacid and laxative. It works by neutralizing stomach acid and providing relief from indigestion and heartburn. It can also help with constipation, which makes it a versatile option. It’s liquid, much like Andrew’s Original Salts, and can be taken when required for quick relief from digestive discomfort.

2. Gaviscon

Gaviscon is a widely used over-the-counter product for heartburn and indigestion. It works by forming a protective barrier on top of the stomach contents, helping to prevent acid reflux. Gaviscon is available in liquid and chewable tablet forms and provides fast relief from the symptoms of acid reflux, indigestion, and bloating.

3. Rennie

Rennie is an antacid that contains calcium carbonate and magnesium carbonate. It works by neutralizing excess stomach acid, providing relief from indigestion, heartburn, and bloating. Rennie comes in chewable tablet form and is often recommended for its fast-acting relief.

4. Peppermint Oil Capsules

For those looking for a more natural option, peppermint oil capsules can provide relief from digestive issues such as bloating, indigestion, and discomfort. Peppermint has been shown to help relax the muscles of the digestive tract, reducing cramping and bloating. It’s available in enteric-coated capsules, which help the oil reach the intestines without irritating the stomach.

5. Simethicone

Simethicone is a commonly used remedy for bloating and trapped gas. It works by breaking down gas bubbles in the stomach and intestines, helping to relieve bloating and discomfort. Simethicone is available in liquid and tablet forms and is a great alternative if your main concern is bloating rather than acid reflux or indigestion.

6. Baking Soda (sodium bicarbonate)

Baking soda is an old home remedy for heartburn and indigestion. It works by neutralizing stomach acid, providing temporary relief from discomfort. Simply mix a small amount of baking soda in water to drink. However, it’s important to use this method sparingly, as excessive use of baking soda can lead to electrolyte imbalances.

7. Apple Cider Vinegar

Although it may seem counterintuitive, some people find relief from heartburn and indigestion by using apple cider vinegar. It’s believed that the acidity helps to balance stomach acid levels. To use it, dilute one to two teaspoons of apple cider vinegar in a glass of water and drink before or after meals. This may help reduce symptoms of acid reflux for some people, but it’s not suitable for everyone, so listen to your body.

8. Probiotics

Probiotics are beneficial bacteria that support gut health and digestion. They can help balance the gut microbiome, improving digestion and reducing symptoms like bloating, indigestion, and gas. Probiotics are available in supplements, yogurts, and fermented foods like kefir and sauerkraut.
