Scott’s Emulsion is a long-established cod liver oil supplement, sold as a thick sweetened liquid and taken by the spoonful. It is used mainly as a general tonic for children — a source of vitamins A and D and omega-3 fatty acids — rather than as a treatment for any particular condition.
What is Scott S Emulsion?
Scott’s Emulsion is a food supplement, not a registered medicine. It does not appear in the South African Medicine Price Registry, and it is not expected to: supplements follow a different regulatory route from scheduled medicines here.
(Searching that register for “emulsion” returns unrelated hospital products — intravenous fat emulsions and nutrition bags — not this product.)
The product’s own labelling describes it as a cod liver oil emulsion. An emulsion means the oil is suspended in a water-based liquid rather than sitting separately, which is what makes it pourable and drinkable instead of an oily dose. That formulation is the reason the product has survived for well over a century: it made cod liver oil possible to give to children.
Cod liver oil is conventionally a source of three things:
- Vitamin A — for vision, skin and immune function.
- Vitamin D — for calcium absorption, bone development and immune function.
- Omega-3 fatty acids, EPA and DHA — for brain, eye and cardiovascular health.
Formulations change, and they differ by country. The amount of each vitamin in the bottle on your shelf is the figure that matters, and only your label carries it. Read it before assuming what you are giving.
What is Scott S Emulsion commonly used for?
It is used as a general nutritional supplement, most often:
- As a children’s tonic, given daily through childhood, particularly in winter.
- For vitamin D, which supports calcium absorption and bone development.
- For vitamin A, supporting vision, skin and immune function.
- For omega-3 intake, particularly where a child eats little oily fish.
- During recovery from illness, or where appetite has been poor.
It is worth being clear about what a supplement of this kind does and does not do.
Where a genuine deficiency exists, correcting it matters. Vitamin D deficiency is common, and severe deficiency in children causes rickets. Vitamin A deficiency remains a major global cause of childhood blindness and infection.
Where no deficiency exists, the benefit is much smaller. A supplement is insurance against a gap in the diet, not a general enhancer. It will not make a well-nourished child stronger, taller or more resistant to colds, and no supplement substitutes for food.
There is also a specific reason to pay attention to the label with this product rather than any other: vitamin A accumulates in the body. Unlike vitamin C, excess is stored rather than excreted, and too much over time causes real harm. That is a dosing question, not a scare — it simply means “a bit extra for good measure” is the wrong instinct here.
Who commonly looks for Scott S Emulsion and why
- Parents and grandparents, often because they were given it themselves as children. It has been sold for generations and is widely recognised in South Africa.
- Parents of fussy eaters, worried a child is not getting enough from food.
- Families through winter, when sunlight exposure drops and vitamin D levels fall with it.
- People recovering from illness, or caring for someone with a poor appetite.
- Adults wanting omega-3 without swallowing capsules, and older people wanting vitamin D for bone health.
- People who dislike fish, looking for the nutrients without the meal.
The underlying question is nearly always the same: is my child getting enough? That is a reasonable question, and a clinic nurse, pharmacist or dietitian can answer it far better than a shelf can — sometimes with a blood test, often with a look at what the child actually eats.
What to check on the label before taking Scott S Emulsion
- The vitamin A and vitamin D content per dose, and the dose for your age group. These are the numbers that matter most, and they differ between formulations and countries.
- Whether the dose is per 5 ml or per larger spoonful — the commonest source of accidental overdosing at home.
- The age from which it is suitable. Do not give it to an infant below the stated age without professional advice.
- Other supplements you or your child already take. Multivitamins, fortified milk formulas and cod liver oil capsules all contribute vitamin A and D. Adding this on top can double an intake without anyone intending to.
- Sugar content, if the product is being given daily to a child, and particularly if dental health is a concern.
- Fish allergy. Cod liver oil is a fish product.
- The expiry date and the storage instructions once opened.
- Use a proper measuring spoon or cup, not a kitchen teaspoon, which varies widely in size.
Safety, interactions and when to seek professional advice
For most people, taken at the stated dose, cod liver oil products are well tolerated. Mild effects include a fishy aftertaste, burping, nausea or loose stools.
Speak to a doctor, pharmacist or clinic nurse before taking it if you or the person taking it:
- Is pregnant or planning pregnancy. This one matters. High-dose vitamin A can harm a developing baby, and cod liver oil supplements are generally avoided in pregnancy unless a professional has advised otherwise.
- Is already taking a multivitamin, another vitamin A or D product, or fortified formula.
- Takes warfarin or another blood thinner — omega-3 in higher amounts can affect bleeding.
- Has liver disease, kidney disease, or a condition causing high blood calcium.
- Has a fish allergy.
- Is an infant, or is due for surgery, where higher-dose omega-3 may be stopped beforehand.
Signs of taking too much are worth recognising. Excess vitamin A over time can cause headache, nausea, blurred vision, dry or peeling skin, hair loss, bone or joint pain and liver problems. Excess vitamin D raises blood calcium, causing thirst, frequent urination, nausea, constipation, confusion and, over time, kidney damage. These come from sustained overdosing, not from a single extra spoonful — but they are the reason to measure doses and to count everything else being taken.
Seek advice promptly for persistent headache, vision changes, unusual tiredness, ongoing nausea or vomiting, unexplained bone or joint pain, or yellowing of the skin or eyes. Get emergency help for swelling of the face or throat, or difficulty breathing.
And see a doctor rather than reaching for a tonic if a child is not gaining weight, is persistently tired, pale or unwell, is repeatedly infected, or has stopped eating properly. Those are symptoms that deserve a diagnosis. A supplement given in their place can delay one.

Frequently asked questions
What is Scott’s Emulsion used for? As a general nutritional supplement — a source of vitamins A and D and omega-3 fatty acids, most often given to children as a daily tonic.
Is it a medicine? No. It is a food supplement and is not registered as a scheduled medicine in South Africa.
What is in it? The label describes a cod liver oil emulsion. Amounts of vitamin A and D vary by formulation, so read the bottle you have.
Can I give it to my baby? Only from the age stated on the pack, and preferably after asking a clinic nurse or pharmacist. Infants have low tolerance for excess vitamin A.
Can I take it in pregnancy? Generally avoided, because high-dose vitamin A can harm a developing baby. Ask your doctor or midwife before taking any cod liver oil product.
Can I take it with a multivitamin? Check both labels first. Vitamin A and D from two sources add up, and doubling them is easy to do unintentionally.
Will it stop my child getting sick? No. It helps fill nutritional gaps; it does not prevent infections. If a child is frequently unwell, see a doctor.
Is it safe with a fish allergy? No. Cod liver oil is a fish product. Ask a pharmacist about a non-fish source of vitamin D and omega-3.
