What Is Complan Strawberry Shake and How Does It Help?

 

The Complan strawberry shake is a nutritionally complete supplement drink designed to help you maintain adequate calorie and nutrient intake when eating enough through food alone becomes difficult. Each 57g sachet contains 26 vitamins and minerals, including vitamin D, calcium, iron, and B vitamins — nutrients that are easy to fall short on during illness, recovery, or periods of reduced appetite. It's a convenient, ready-to-mix option that takes just moments to prepare, making it genuinely practical for everyday use.

Complan has been a trusted name in nutritional support in the UK for decades. Manufactured by Nutricia, the brand sits within a wider portfolio of products aimed at supporting people who need extra nutritional help. Whether you're recovering from surgery, managing a long-term condition, or simply finding it hard to eat enough, a supplement shake like this can play a useful supporting role alongside a balanced diet. You might also want to explore our range of vitamins and supplements for additional nutritional support options.

 

How Does Complan Shake Work to Support Nutrition?

 

Complan Shake works by delivering a concentrated source of energy, protein, carbohydrates, fat, and micronutrients in a single drink. When mixed with water or milk, each sachet provides a calorie-dense, nutrient-rich serving that helps bridge the gap between what you're eating and what your body actually needs.

  • Provides energy from carbohydrates and fat to support daily caloric requirements
  • Contains protein to help maintain muscle mass, particularly important during recovery or illness
  • Delivers 26 vitamins and minerals including vitamin C, zinc, and iron to support immune function and general health
  • Dissolves easily in water or milk, making it accessible even when appetite is very low

 

Who Should Consider Using Complan Shake Sachets?

 

This product is suitable for adults and children over five years of age who need additional nutritional support. It's particularly useful for people who are underweight, recovering from illness or surgery, or who have a medical condition that affects their ability to eat normally. It is not intended to replace a varied, balanced diet in healthy individuals who have no nutritional concerns.

  • Adults with reduced appetite due to illness, surgery, or ageing
  • People who are underweight or at risk of malnutrition
  • Those recovering from a hospital stay or medical procedure
  • Individuals with conditions that increase nutritional requirements

For long-term use, it's worth speaking to your GP or a registered dietitian to ensure your overall nutritional needs are being met. If you're managing a condition that affects your diet — such as a digestive issue — you may also find it helpful to browse our IBS and cramps range for complementary support products. The Complan strawberry shake is not intended as a sole source of nutrition unless under medical supervision.

Specifications of Complan Shake Strawberry Flavour Sachets 57g

 

What Is Complan Shake Strawberry and What Is It Used For?

 

Complan Shake Strawberry Flavour Sachets 57g is a nutritionally complete food supplement drink produced by Nutricia. It is used to help increase calorie and nutrient intake in people who are unable to meet their nutritional requirements through food alone. This might be due to illness, surgery, ageing, or a medical condition that reduces appetite or increases the body's nutritional demands.

Each sachet, when mixed with water or milk, provides a source of energy, protein, carbohydrates, fat, and 26 vitamins and minerals. It is not a licensed medicine — it is classified as a food for special medical purposes (FSMP) category supplement and is available without a prescription. It is suitable for adults and children over five years of age.

 

What Do You Need to Know Before Using Complan Shake?

 

Before using Complan Shake, check the following contraindications and warnings carefully:

  • Not suitable for children under 5 years of age as a sole source of nutrition
  • Contains milk — not suitable for people with a cow's milk protein allergy or lactose intolerance
  • People with phenylketonuria (PKU) should check the phenylalanine content before use
  • If you have diabetes, consult your GP or diabetes care team before use, as the product contains carbohydrates and sugars
  • Not recommended as a sole source of nutrition unless under medical supervision
  • If you are pregnant or breastfeeding, seek medical advice before using regularly

Regarding drug interactions, no clinically significant interactions have been identified for Complan Shake as a food supplement. However:

  • High vitamin K content may theoretically affect anticoagulant therapy — if you take warfarin, speak to your GP or anticoagulation clinic
  • High mineral content (calcium, iron, zinc) may affect absorption of certain antibiotics or thyroid medications if taken simultaneously — separate by at least two hours

 

How Should You Use Complan Shake Sachets?

 

  1. Open one 57g sachet of Complan Shake Strawberry powder
  2. Pour the powder into a clean cup or shaker bottle
  3. Add approximately 200ml of warm or cold water, or full-fat milk for extra calories
  4. Stir vigorously or shake well until the powder is fully dissolved and no lumps remain
  5. Drink immediately, or cover and refrigerate — consume within 24 hours if refrigerated
  6. Discard any unused portion after 24 hours
Indication Age Group Dose Frequency

What Are the Possible Side Effects of Complan Shake?

 

As a food supplement rather than a licensed medicine, Complan Shake does not have a formal side effect profile in the same way a drug would. However, some people do experience digestive discomfort, particularly when first introducing it. If you're also managing digestive health concerns, our indigestion range may offer additional support.

Common side effects:

  • Bloating or wind, especially when first starting
  • Nausea if consumed too quickly
  • Feeling of fullness or heaviness

Less common side effects:

  • Diarrhoea, particularly if lactose intolerant
  • Stomach cramps
  • Allergic reaction in those with milk protein allergy (rash, itching, swelling — seek urgent medical attention)

 

How Should You Store Complan Shake Sachets?

 

Proper storage helps maintain the quality and nutritional value of the product. If you're building a broader health routine, you might also find our weight loss range worth exploring alongside nutritional supplements.

  • Store unopened sachets in a cool, dry place below 25°C
  • Keep away from direct sunlight and moisture
  • Do not store near strong odours — the powder can absorb them
  • Once mixed, consume immediately or refrigerate and use within 24 hours
  • Do not freeze the prepared drink
  • Keep out of reach of children
  • Do not use after the expiry date printed on the sachet

Frequently Asked Questions

Where can I buy Complan Strawberry Shake Sachets online in the UK?

You can buy Complan Shake Strawberry Flavour Sachets 57g directly from Cured Pharmacy, a GPhC-registered UK online pharmacy. Simply add the product to your basket and select your preferred delivery option at checkout. Orders are dispatched promptly and delivered to your door across the UK.

How does Complan Shake work in the body?

Complan Shake delivers a concentrated blend of carbohydrates, protein, fat, and 26 vitamins and minerals in a single drink. When consumed, these nutrients are absorbed through the digestive tract to help meet daily energy and micronutrient requirements. It is particularly useful when dietary intake alone is insufficient to cover the body's needs.

How do I make up a Complan Shake sachet step by step?

Empty one 57g sachet into a clean cup or shaker, add around 200ml of warm or cold water or full-fat milk, then stir or shake until fully dissolved. Drink straight away for the best taste and nutritional quality. If you can't finish it immediately, cover and refrigerate it — but use it within 24 hours.

How many Complan sachets can I have in one day?

Adults can generally have up to two sachets per day as a supplement alongside their normal diet. Children over five should have no more than one sachet daily, and ideally under the guidance of a dietitian. If you are considering using Complan as your only source of nutrition, always speak to your GP first.

What is the best time to take Complan Shake?

There is no single "best" time — it depends on your individual routine and why you're using it. Many people find it helpful between meals or as a breakfast replacement when appetite is low in the morning. Others use it as a late-evening supplement to boost calorie intake before bed.

Can Complan Shake cause side effects?

Some people experience bloating, wind, or mild nausea when they first start using Complan Shake, especially if they drink it quickly. These effects usually settle within a few days as your digestive system adjusts. If you develop a rash, swelling, or difficulty breathing, stop use immediately and seek medical attention as this could indicate an allergic reaction.

How do I manage digestive side effects from Complan Shake?

Start with a smaller amount — perhaps half a sachet — and gradually increase to a full serving over several days to allow your gut to adapt. Drinking slowly rather than gulping the shake down can also reduce bloating and nausea. If symptoms persist, speak to your pharmacist or GP.

Is Complan Shake suitable for people with diabetes?

Complan Shake contains carbohydrates including sugars, which can affect blood glucose levels. If you have diabetes, you should consult your GP or diabetes care team before using it regularly. Monitoring your blood glucose more closely when you first introduce it is a sensible precaution — you can find relevant monitoring tools in our diabetes monitoring range.

Who is eligible to use Complan Shake Sachets?

Complan Shake is suitable for adults and children over five years of age who need additional nutritional support. It is particularly appropriate for people who are underweight, recovering from illness or surgery, or who have a condition that reduces appetite or increases nutritional needs. It is not suitable for children under five as a sole source of nutrition.

Is Complan Shake suitable for vegetarians?

Yes, Complan Shake is suitable for vegetarians as it does not contain meat or fish-derived ingredients. However, it does contain milk-derived ingredients, so it is not suitable for vegans. Always check the current product label for the most up-to-date ingredient information.

What happens if I miss a serving of Complan Shake?

If you forget to have your Complan Shake at the usual time, simply have it when you remember — there is no need to double up on servings. Missing one serving occasionally will not cause harm, but try to maintain a consistent routine to get the most benefit from it. Do not take two sachets at once to compensate for a missed one.

What are the alternatives to Complan Shake in the UK?

Other nutritional supplement drinks available in the UK include Fortisip, Ensure Plus, and Fresubin, which come in various flavours and formulations. Some of these are available on NHS prescription for people who meet clinical criteria for malnutrition. Your GP or a registered dietitian can advise on the most appropriate option for your specific situation.

How does Complan Shake compare to a standard meal replacement shake?

Unlike many commercial meal replacement shakes aimed at weight loss, Complan Shake is designed to supplement nutrition and support calorie intake — not to reduce it. It contains a broader range of vitamins and minerals than most diet shakes and is formulated for people with increased nutritional needs rather than those looking to cut calories. If weight management is your goal, our weight loss range may be more appropriate.

How long can you use Complan Shake for?

Complan Shake can be used for as long as nutritional supplementation is needed, but long-term use — particularly as a meal replacement — should be reviewed by a GP or dietitian. They can assess whether your nutritional needs are being met and whether any adjustments to your diet or supplement routine are required. There is no fixed maximum duration for use as a dietary supplement.

What are the latest findings on nutritional supplement drinks like Complan?

NICE guidance (CG32) on nutrition support in adults recommends oral nutritional supplements for people who are malnourished or at risk of malnutrition and who cannot meet their needs through food alone. Research consistently supports the use of nutritional supplement drinks in improving calorie and protein intake in older adults and those recovering from illness. Always follow the advice of your healthcare team when using these products as part of a clinical nutrition plan.

How Should You Use Complan Shake Strawberry Sachets?

Complan Shake Strawberry is simple to prepare and can be made with either water or milk depending on your preference and calorie needs. Using full-fat milk instead of water will increase the calorie and protein content of each serving, which may be beneficial if you are trying to gain weight or recover from illness.

What Is the Correct Dose of Complan Shake?

The appropriate number of sachets per day depends on your age and the reason you are using the product. As a general guide, adults should not exceed two sachets per day when using Complan as a supplement alongside meals. Always follow the advice of your GP or dietitian if you have been recommended this product for a specific medical reason.

When Is the Best Time to Use Complan Shake?

There is no single best time — it really depends on your daily routine and why you are using it. Many people find it most useful between meals when appetite is low, or as a breakfast option when eating solid food first thing in the morning feels difficult. Others prefer it as an evening supplement to top up their calorie intake before bed, particularly during recovery from illness or surgery.

How Long Can You Use Complan Shake For?

Complan Shake can be used for as long as you need additional nutritional support. However, if you are using it as a meal replacement rather than a supplement, it is important to review this with your GP or a registered dietitian to ensure your full range of nutritional needs is being met over time. Regular review helps ensure the product remains appropriate for your situation and that your diet is as varied and balanced as possible.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of Complan Shake?

As a food supplement rather than a licensed medicine, Complan Shake does not carry a formal adverse effects profile in the same way a pharmaceutical product would. That said, some people do notice digestive discomfort when they first introduce it, particularly if they are not used to high-calorie supplement drinks. These effects are usually mild and tend to resolve on their own within a few days.

  • Bloating or a feeling of fullness
  • Flatulence (wind)
  • Mild nausea, especially if consumed quickly
  • Stomach heaviness after drinking

What Are the Less Common Side Effects of Complan Shake?

Less commonly, some individuals may experience more noticeable digestive symptoms, particularly those with underlying sensitivities to dairy or certain carbohydrates. If you have a known intolerance, check the ingredient list carefully before use.

  • Diarrhoea, particularly in those with lactose sensitivity
  • Stomach cramps or abdominal discomfort
  • Constipation if fluid intake is not maintained alongside use
  • Changes in stool consistency or frequency

What Are the Serious Side Effects of Complan Shake?

Serious reactions to Complan Shake are rare but can occur in people with a cow's milk protein allergy. Symptoms of an allergic reaction can include skin rash, itching, swelling of the face, lips, or throat, difficulty breathing, or a sudden drop in blood pressure. These symptoms require immediate medical attention — call 999 or go to your nearest A&E department without delay.

What Should You Do If You Experience Side Effects?

If you notice mild digestive side effects such as bloating or nausea, try reducing your serving size initially and building up gradually over several days. Drinking the shake slowly rather than all at once can also help. If symptoms are persistent, worsening, or causing significant discomfort, stop use and speak to your pharmacist or GP for advice.

Can Complan Shake Interact With Other Medicines?

No clinically significant drug interactions have been identified for Complan Shake as a food supplement. However, the product contains vitamin K, which may theoretically affect the action of anticoagulant medicines such as warfarin — if you take a blood thinner, speak to your GP or anticoagulation clinic before using regularly. The mineral content (calcium, iron, zinc) may also reduce the absorption of certain antibiotics (such as tetracyclines or fluoroquinolones) and levothyroxine if taken at the same time — separate administration by at least two hours to minimise this risk.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
