What Is OneVit Complete?
OneVit Complete is a daily multivitamin and mineral supplement designed to provide a broad range of micronutrients in a convenient single tablet.
It contains 27 vitamins, minerals and additional micronutrients, making it a comprehensive option for supplementing a varied and balanced diet.
The formula includes nutrients involved in many normal bodily functions, including energy metabolism, immune function, bone health and protection of cells from oxidative stress.
OneVit Complete should not be viewed as a replacement for nutritious food. Instead, it is intended to supplement a balanced diet where additional micronutrient support may be appropriate.
For people following a medically supported weight-management programme, maintaining good nutritional intake remains important alongside calorie reduction.

What Are the Benefits of OneVit Complete?
OneVit Complete provides a broad range of micronutrients rather than concentrating on a single vitamin.
Its formulation can contribute to several normal physiological functions.
Immune System Support
Nutrients including vitamins A, C and D, along with selenium and zinc, contribute to normal immune-system function.
Energy Metabolism
B vitamins including B1, B2, B3, B5, B6 and B12 contribute to normal energy-yielding metabolism.
Reduction of Tiredness and Fatigue
Several nutrients contained in the formula, including vitamin C, vitamin B6, vitamin B12, folate and iron, contribute to reducing tiredness and fatigue.
Bone and Muscle Support
Vitamin D contributes to the maintenance of normal bones and muscle function, while calcium is needed for the maintenance of normal bones.
Protection From Oxidative Stress
Vitamin C, vitamin E, selenium and zinc contribute to protecting cells from oxidative stress.
These benefits refer to the established physiological roles of the individual nutrients and should not be interpreted as OneVit preventing or treating disease.
Why Take a Multivitamin During Weight Management?
Reducing calorie intake is often an important component of weight loss.
However, eating fewer calories can make the quality of the foods you choose particularly important.
A well-designed weight-management diet should continue to provide:
- adequate protein;
- vegetables and fruit;
- fibre;
- essential fats;
- vitamins; and
- minerals.
A multivitamin can complement this approach where additional micronutrient support is appropriate.
It should not replace healthy food or be used as a substitute for a balanced diet.

Why Take Vitamins With Orlistat?
This is particularly relevant to MySlimCare customers using orlistat-based treatments.
Orlistat reduces the absorption of dietary fat.
Because vitamins A, D, E and K are fat-soluble, treatment with orlistat may also reduce their absorption.
European product information therefore advises people using orlistat to maintain a diet rich in fruit and vegetables and states that use of a multivitamin supplement may be considered.
OneVit Complete contains all four of these fat-soluble vitamins:
- Vitamin A
- Vitamin D
- Vitamin E
- Vitamin K
This makes it a potentially convenient supplement for people whose healthcare professional has recommended multivitamin supplementation during orlistat treatment.
Can I Take OneVit Complete With Orlistat?
A multivitamin can generally be used alongside orlistat, but timing matters.
Because orlistat reduces fat absorption, taking your multivitamin at exactly the same time may reduce absorption of some of its fat-soluble vitamins.
OneVit guidance recommends taking the multivitamin at least two hours before or after orlistat.
For example, someone taking orlistat with their main meals might take their multivitamin later in the evening.
Always follow the instructions supplied with your products and any advice given by your healthcare professional.
Can I Take OneVit Complete With Xenical?
Xenical contains 120mg orlistat.
Because orlistat can interfere with absorption of fat-soluble vitamins, a multivitamin may be considered as part of an appropriate nutritional plan.
OneVit Complete should be separated from the orlistat dose rather than taken simultaneously.
Can I Take OneVit Complete With Alli?
Alli contains 60mg orlistat.
Like other orlistat products, Alli can reduce absorption of some vitamins. Current Alli information advises taking a multivitamin daily while using orlistat.
OneVit Complete contains vitamins A, D, E and K alongside a range of additional vitamins and minerals.
Can I Take OneVit Complete With Orlos?
Orlos is another orlistat-based weight-management product.
The same principle applies: because orlistat can affect absorption of fat-soluble vitamins, a multivitamin may be appropriate.
Take the supplement separately from your orlistat dose according to the product directions.
Can I Take OneVit Complete With Other Weight Loss Treatments?
OneVit Complete is a nutritional supplement rather than a weight-loss medicine.
However, that does not mean every supplement is automatically appropriate with every medication.
If you use prescription weight-management medicines or medicines for other medical conditions, tell your healthcare professional about any vitamins and supplements you take.
This is particularly important where medicines can interact with individual minerals or vitamins.

How Do I Take OneVit Complete?
The recommended use is straightforward:
Take one tablet once daily.
It can normally be taken with food or water.
If you are using an orlistat-containing medicine, take OneVit Complete at least two hours before or after the orlistat dose.
Do not exceed the recommended daily amount.
When Is the Best Time to Take OneVit Complete?
For most people, the important factor is taking the supplement consistently according to its directions.
If you are taking orlistat, timing becomes more important.
A practical option may be taking your multivitamin in the evening or at bedtime, provided this leaves sufficient separation from your last orlistat dose.
The most appropriate routine may vary according to your other medicines.
Is OneVit Complete Suitable for Vegetarians?
Yes. Available product information identifies OneVit Complete as suitable for vegetarians.
Is OneVit Complete Vegan?
Do not assume vegetarian and vegan mean the same thing.
Although OneVit Complete is identified as suitable for vegetarians, customers following a strict vegan diet should verify the current packaging or manufacturer information before purchasing.
Is OneVit Complete Gluten-Free?
Available product information states that OneVit Complete is free from:
- gluten;
- nuts;
- dairy;
- lactose;
- soya; and
- eggs.
It is also identified as suitable for vegetarians.
Always check the current product packaging if you have a diagnosed allergy or intolerance, as formulations can change.
Does OneVit Complete Contain Vitamin D?
Yes.
Each tablet contains 15µg of vitamin D, equivalent to 300% of the listed Nutrient Reference Value in the available product specification.
Vitamin D contributes to:
- normal immune-system function;
- maintenance of normal bones;
- maintenance of normal muscle function; and
- normal absorption and utilisation of calcium and phosphorus.
Does OneVit Complete Contain Vitamin B12?
Yes.
OneVit Complete contains 22µg of vitamin B12 per tablet.
Vitamin B12 contributes to normal:
- energy-yielding metabolism;
- nervous-system function;
- psychological function;
- red blood cell formation; and
- immune-system function.
It also contributes to reducing tiredness and fatigue.
Does OneVit Complete Contain Iron?
Yes.
Each tablet contains 5mg of iron.
Iron contributes to several normal functions, including:
- formation of red blood cells and haemoglobin;
- oxygen transport;
- energy metabolism;
- cognitive function; and
- reduction of tiredness and fatigue.
Does OneVit Complete Help You Lose Weight?
OneVit Complete should not be marketed as a weight-loss medicine.
It does not replace:
- calorie control;
- physical activity;
- behavioural changes; or
- appropriate weight-management treatment.
Instead, its role is nutritional.
It provides vitamins and minerals that can complement a balanced diet, including during a structured weight-management programme.
This distinction is important for both accurate customer information and responsible supplement marketing.
Can OneVit Complete Replace a Healthy Diet?
No.
Food supplements should complement rather than replace a varied and balanced diet.
Whole foods provide protein, fibre, essential fats, carbohydrates and numerous other compounds that cannot simply be replaced by a multivitamin tablet.
OneVit Complete is best viewed as an addition to good nutrition, not an alternative to it.
Who Should Check Before Taking OneVit Complete?
Speak with a healthcare professional before starting a multivitamin if you:
- are pregnant or breastfeeding;
- take prescription medicines;
- have a medical condition;
- already use other vitamin or mineral supplements;
- have been advised to restrict a particular nutrient; or
- are unsure whether the product is suitable for you.
Combining several supplements containing the same nutrients can result in unnecessarily high total intakes.
