bariboost
Designed in the UK. Crafted for life after bariatric surgery
If you’ve had gastric sleeve, bypass, or duodenal switch surgery, your nutritional needs are different. Bariboost was created to meet those needs properly — with the right nutrients, at bariatric doses, in forms your body can actually absorb.


Why Bariboost Bariatric Multivitamin Exists
After bariatric surgery, your nutritional needs change — dramatically and vitamin deficiencies aren’t just possible — they’re common.
Iron, B12, vitamin D, folate, thiamine and trace minerals are harder to absorb, even years after surgery. Many patients are told to “take a multivitamin” — but most off‑the‑shelf products are not bariatric‑appropriate, are underdosed, overcomplicated, or not aligned with BOMSS guidance.
why bariboost?
Bariboost was created to solve that problem
• BOMSS aligned doses for sleeve, bypass & mini bypass

Why We Chose These Forms
- Better tolerated than ferrous sulphate/fumarate
- Chelated form of iron
- Highly bioavailable and absorbable
- Less stomach and digestive problems like constipation
- Gentle on the stomach
Bariboost bariatric multivitamin contains 50mg of iron bisglycinate (ferrous bisglycinate) which is a gentle form of iron.
The ideal form of iron required by the bariatric patient should contain enough elemental ion, be highly bioavailable (easily absorbed) with low risk of gastro-intestinal (GI) side effects to promote adherence and reduce risk of iron deficiency anaemia after bariatric surgery.
Most multivitamins and bariatric multivitamins brands use ferrous fumarate, ferrous gluconate or ferrous sulphate in their formulation. Ferrous fumarate and ferrous sulphate has poor bioavailability and causes significant side effects. Ferrous gluconate does not contains enough elemental iron.
At Bariboost, we use Iron bisglycinate also known as ferrous bisglycinate as it is the superior form of supplemental iron and has shown greater benefit over other iron supplements in increasing haemoglobin concentration with reduced GI side effects.
Iron bisglycinate is an amino acid chelate. Chelated iron bisglycinate is formed by binding iron to two molecules of the amino acid glycine. Think about it like a chicken sandwich with two slices of bread (amino acid glycine) and a slice of chicken (iron). This unique structure is similar to complexes naturally occurring in our bodies and allows for improved absorption. Iron bisglycinate does not form insoluble compounds with iron absorption blockers like dietary phytates and tannins which means they are less affected by them. Phytates are mainly found in cereal grains, nuts and legumes while tannins are primarily found in coffee, tea, legumes and some cereal gains.
The chelated form is also more soluble, which means better absorption and better absorption in turn reduces gastrointestinal side effects like heartburn, nausea, constipation, diarrhoea and abdominal pain.
BOMSS Guidance recommends between 45 to 60 mg and 100 mg of elemental iron daily for menstruating women. Bariboost contains 50mg of elemental iron. As chelated ions are better absorbed, a lower doses can be used compared to ferrous fumarate and ferrous sulpate where the bioavailability of supplemented iron ions is very low.
Evidence suggests that ferrous bisglycinate 25 mg elemental iron is as effective as ferrous sulphate 50 mg elemental iron (ferrous sulphate 200 mg is equivalent to 65 mg elemental iron). Using a lower dose treatment simultaneously reduces the chances of side effects and increases the safety of therapy. A study of the tolerability of iron bisglycinate versus ferrous sulphate showed that more people preferred the bisglycinate form because it caused less GI upset.
BOMMS recommends regular bloods monitoring including monitoring of iron levels.
- Methylcobalamin is natural and more bioavailable than the synthetic cyanocobalamin
- Methylcobalamin is the active, body-ready form of Vitamin B12

Clean Formula
Rice concentrate (or rice hulls) is the fibre and silica part of the outer layer of rice and does not contain any of the white rice.
It is a natural source of silica and one of the most effective anti-caking agents available. Most other food supplement companies use synthetic anti-caking agents like Silicon Dioxide. Bariboost uses a small amount of a natural, certified organic and gluten-free rice concentrate powder.
The rice concentrate powder we use is made by a patent-pending process to grind the sterilized rice hulls in such a way that the silica particle size is optimized for use as flow agents in food supplements.
As rice naturally takes up silica from the soil and concentrates it in its hulls, it produces a healthy and natural alternative to other synthetic anti-caking/flow agents like silicon dioxide.

Bariboost uses Bamboo Leaf Extract as flow agent. Bamboo is a fast-growing plant that are distributed in tropical and subtropical to mild temperate regions. Its shoots, leaves and stems have been used in many Asian cuisine delicacies for centuries.
Bamboo is a rich source of natural silica extract. The extract used by Bariboost is derived from the leaves of the Bambusa vulgaris plant. These evergreen leaves contain about 70% silica as they absorb silica from the soil and continue to accumulate it throughout their life. However, since the leaves contain toxic levels of cyanide, only properly processed extract form is used.
Bamboo Leaf Extract 75% Silica has been suggested to be beneficial for mineral absorption and has therapeutic effect for improving the health of your bones, joints, hair, skin, and nails.

Pullulan capsules used in Bariboost are edible, tasteless, odourless, organic, natural plant-based and vegan capsules made from fermented tapioca starch and contains absolutely no animal products. They are safe, stable, easy to swallow, easily digested, and offer protection for oxygen-sensitive and moisture-sensitive ingredients.
Pullulan does not react or cross link with the contents of the capsules. It is also not absorbed by the human body which means that only the content of the capsule is absorbed.

Capsules are purer as unlike tablets, they do not require additives like binders and coatings to maintain its shape. The pullulan capsules we use break down easier in the body, which makes the vitamins and minerals contained more readily available for the body to digest and absorb.
Bariboost contains no animal-derived ingredients.
✓ Vegan vitamin D3 from lichen
✓ Pullulan capsules (not gelatin)
✓ Suitable for vegetarians and vegans
✓ No animal products used in the formulation
built by a bariatric patients for biariatric patients
Built from a real bariatric journey — just like yours
Bariboost wasn’t created in a boardroom. It started with one person, post‑surgery, overwhelmed by the number of tablets, the conflicting advice, and the fear of getting it wrong. After months of frustration with products that didn’t meet BOMSS standards, they decided to create the supplement they wished existed — one that was simple, safe, and genuinely supportive. Bariboost is more than a vitamin. It’s a promise that no bariatric patient should feel alone or confused about their nutrition again.

Frequently Asked Questions
After bariatric surgery, the body’s ability to absorb and process nutrients can be reduced. Bariboost uses methylated vitamins such as methylcobalamin (Vitamin B12) and L-methylfolate because they are already in their active, body-ready forms.
Unlike standard forms that require additional conversion steps, methylated vitamins can be used by the body immediately. This makes them a practical choice for long-term supplementation after gastric sleeve, gastric bypass, and mini gastric bypass surgery.
Bariboost uses:
Methylcobalamin (active Vitamin B12)
Calcium L-methylfolate (active folate)
- Active forms
- Highly bioavailable
- Ready for the body to use
- Designed for long-term bariatric support
Chelated minerals are minerals that are bound to amino acids. This structure helps protect the mineral during digestion and may improve absorption and tolerance.
Because nutrient absorption can be affected after bariatric surgery, Bariboost uses carefully selected chelated minerals including iron bisglycinate, copper bisglycinate and magnesium glycinate.
Many bariatric patients also experience stomach sensitivity. Chelated minerals are often better tolerated and may cause fewer digestive complaints than some traditional forms.
Bariboost includes:
Iron Bisglycinate
Copper Bisglycinate
Magnesium Glycinate
- Highly bioavailable
- Better tolerated
- Gentle on the stomach
- Designed for post-bariatric nutritional support
Bariboost does not contain calcium by design.
Calcium and iron are commonly recommended after bariatric surgery, but they should generally be taken separately because calcium can interfere with iron absorption when taken at the same time.
Bariboost contains 50mg of iron and is formulated to provide key bariatric vitamins and minerals without compromising iron absorption. By keeping calcium separate, patients can take their calcium supplement at a different time of day and follow common bariatric supplementation practices.
This approach also allows greater flexibility, as calcium requirements can vary between individuals.
- Supports optimal iron absorption
- Aligns with common bariatric supplementation practices
- Allows calcium to be taken separately
- Provides greater flexibility for individual needs
Typical routine:
- Bariboost Multivitamin: 2 capsules daily
- Calcium + Vitamin D supplement: taken separately
- Vitamin B12 injections: as advised by your bariatric team or healthcare professional
This simple approach helps many bariatric patients reduce tablet burden while maintaining long-term nutritional support.
Yes. Bariatric multivitamins are specifically formulated for people who have had gastric sleeve, gastric bypass, mini bypass, or duodenal switch surgery. After bariatric surgery, nutrient absorption changes and the risk of deficiencies increases. Standard high-street multivitamins are often not designed to provide the levels of iron, vitamin B12, folate, zinc, copper, and other nutrients commonly required following bariatric surgery.
Bariboost contains bariatric-appropriate doses and carefully selected nutrient forms, including methylated vitamins and chelated minerals, to support long-term nutritional needs after surgery.
Bariatric vitamin supplementation is generally recommended for life.
Procedures such as gastric sleeve, gastric bypass, and duodenal switch permanently alter how nutrients are absorbed. Without appropriate supplementation, nutritional deficiencies can develop months or even years after surgery.
For this reason, bariatric patients are usually advised to take vitamins and minerals for life and to have regular blood tests to monitor their nutritional status.
Bariboost was designed with bariatric patients in mind.
If you struggle to swallow capsules, Bariboost capsules can be opened and the contents mixed with water, juice, or yogurt.
This makes Bariboost suitable for many patients during the early post-operative stages or for anyone who finds swallowing capsules difficult.
No.
Bariboost is not intended for use during pregnancy because it contains levels of Vitamin A that are formulated for bariatric patients and may not be suitable during pregnancy.
If you are pregnant, planning a pregnancy, or become pregnant while taking Bariboost, seek advice from your bariatric team, GP, or healthcare professional regarding appropriate supplementation.
Yes. Bariboost was specifically formulated for people who have undergone bariatric surgery.
The formula contains bariatric-level doses of vitamins and minerals that may not be appropriate for the general population. Bariboost is designed for the unique nutritional requirements of gastric sleeve, gastric bypass, mini bypass, and duodenal switch patients.
If you have not had bariatric surgery, you should seek advice from a healthcare professional before using a bariatric multivitamin.
Yes. The British Obesity and Metabolic Surgery Society (BOMSS) recommends regular vitamin B12 supplementation following bariatric surgery, often through intramuscular injections.
Bariboost contains 500mcg of methylcobalamin, the active form of vitamin B12, but it can be taken safely alongside your recommended B12 injections.
Vitamin B12 is a water-soluble vitamin and excess amounts are generally excreted by the body. Bariboost is designed to complement—not replace—the recommendations of your bariatric team.
Always follow the advice of your bariatric surgeon, specialist nurse, dietitian, or healthcare provider.
For many gastric sleeve and gastric bypass patients, Bariboost can replace multiple separate supplements and simplify their daily routine.
Most people will not need additional iron, folic acid, or vitamin D supplementation unless specifically advised by their healthcare professional.
However, most bariatric patients will still need:
- A separate calcium and vitamin D supplement
- Regular vitamin B12 injections if recommended by their bariatric team
- Routine blood monitoring
For many patients, a simple routine of Bariboost, calcium, and vitamin B12 injections provides comprehensive long-term nutritional support.
Yes. Bariboost is 100% vegan and vegetarian.
Features include:
- Vegan Vitamin D3 from lichen
- Pullulan capsules instead of gelatin capsules
- No animal-derived ingredients
- Suitable for vegetarians and vegans
