What sets Bonusan supplements apart
Bonusan is a Dutch supplement company from Numansdorp. It was founded in 1966 by the Bogaerds family and is still run by the third generation. Products are developed in its own factory, together with health professionals across Europe. That background shows in the catalogue: more than 350 specialist products, from standardised herbal formulas to single nutrients. You will find it among our full brand range.
The nutrient forms do the work
Bonusan tends to use forms the body can use straight away. In the multivitamins, vitamin B6 appears as pyridoxal-5-phosphate, vitamin B12 as methylcobalamin and folate in its active form. Vitamin K2 is supplied as menaquinone-7. Magnesan Forte Plus, on the shelves for over twenty years, combines magnesium malate and citrate with taurine and L-glycine, which is unusual in a magnesium tablet. Formulas leave out synthetic colours, flavours and fragrances, and most avoid gelatin, yeast and sucrose.
What the range covers
- Basics: multivitamins, vitamin C as an ascorbate complex, and vitamin D3 options including D3 with K2.
- Gut: the Bacteri products, with Bacteri 17 offering 17 bacterial strains in sachets.
- Herbal formulas: standardised extracts such as the ginseng, rhodiola and schisandra blend in Relaxonyl.
- Specialist: lactoferrin, a Topsport line for athletes, and cPNI products written for certified PNI therapists.
Why we stock Bonusan at BONO
We look at three things before a brand goes on our shelves: the form of the ingredient, the dosage, and whether a combination makes sense. Bonusan scores well on all three, which is why it sits alongside brands we already trust. We are not pushing it for margin; we carry it because the labels are specific and the forms are the ones we would choose ourselves. We buy directly from the brand, so you get authentic stock, our compliance team checks every product before it goes live, and independent labs spot-check batches. Curious about the rest of our method? Read how we select our brands.
Who it suits, and what to expect
Bonusan fits you if you already read labels and want to know exactly which form of a nutrient you are taking. Many buyers come to the brand through an osteopath, dietitian or therapist, but you do not need a referral for the general range. The honest part: it costs more than a supermarket multivitamin, because active forms and standardised extracts are more expensive raw materials. If price matters more to you than the specific form, a simpler product may serve you just as well.
Two more practical points. Give a daily supplement two to three weeks of consistent use before you judge it; nutrient levels move slowly. And check the label if you avoid animal ingredients: the D3 in Bone Formula is vegan, but the krill oil capsule wall uses fish gelatin and lactoferrin comes from milk. The cPNI products are the one part of the range where advice from a certified PNI therapist is genuinely worth having first, since they are dosed around a personal plan.
Frequently asked questions
What kind of brand is Bonusan?
Bonusan is a Dutch family company that makes food supplements in its own factory in Numansdorp. It was founded in 1966 and is now in its third generation. The range is broad, more than 350 products, and covers vitamins, minerals, amino acids, fatty acids, probiotics and standardised herbal formulas. Formulas are developed with health professionals, which is why labels name the exact nutrient form rather than just the nutrient.
Where are Bonusan supplements made?
In the Netherlands, at the company's own production site in Numansdorp, which has been in use since 1968. Making products in house means the brand controls sourcing, formulation and testing in one place instead of handing it to a third party. Practically, that gives you traceable batches and consistent formulas. We buy our stock directly from the brand, with no intermediaries, so what arrives with you is authentic.
Which nutrient forms does Bonusan use, and does that matter?
Yes, the form decides how much work your body has to do before it can use a nutrient. Bonusan mostly picks forms that are already active, so no conversion step is needed. That is one of the main reasons we carry the brand.
| Nutrient | Form used | Why that choice |
|---|---|---|
| Vitamin B6 | Pyridoxal-5-phosphate | Already active form |
| Vitamin B12 | Methylcobalamin | Usable without conversion |
| Folate | Active folate | Skips a conversion step |
| Vitamin K2 | Menaquinone-7 (MK-7) | Long half-life form |
| Magnesium | Malate and citrate | Well absorbed forms |
Are Bonusan supplements suitable for vegans or people with allergies?
Some are, some are not, so read the label per product. The vitamin D3 in Bone Formula is vegan, and many tablets use cellulose capsules or fillers. But the krill oil capsule wall contains fish gelatin, lactoferrin is made from milk protein, and the Bacteri sachets use maltodextrin, inulin and FOS as carriers. The brand leaves out synthetic colours, flavours and fragrances, though functional additives such as sorbitol are used where a capsule needs to stay flexible.
How do I take them, and how long before I notice anything?
Most Bonusan tablets and capsules are meant to be taken during or straight after a meal, which helps with fat-soluble nutrients such as vitamin D3 and omega-3. The Bacteri sachets are different: they are mixed into a glass of water, preferably on an empty stomach before bed or half an hour before breakfast. Give any daily supplement two to three weeks of consistent use before judging it. With probiotic supplements, some wind in the first week is common and usually settles.
Why do Bonusan supplements cost more than supermarket vitamins?
Because of what goes into them. Active forms such as pyridoxal-5-phosphate, methylcobalamin and MK-7 cost more per gram than the cheaper basic forms, and standardised herbal extracts are pricier than plain powders. You also pay for testing: the brand checks quality in its own laboratory and again externally. That is a fair trade if you care about the exact form on the label. If you only need to top up a basic daily amount, a simpler product can be enough.
How much vitamin D should adults in the UK take?
UK guidance is 10 micrograms (400 IU) a day for most people, and everyone is advised to consider a supplement during autumn and winter, when sunlight here is too weak. That matters when reading Bonusan labels, because products such as Vitamin D3 75 are dosed well above the basic amount. Use the reference values below to see where a product sits.
| Group | Daily amount | Do not exceed |
|---|---|---|
| Adults and 11 to 17 years | 10 mcg (400 IU) | 100 mcg (4,000 IU) |
| Children 1 to 10 years | 10 mcg (400 IU) | 50 mcg (2,000 IU) |
| Babies under 12 months | 8.5 to 10 mcg | 25 mcg (1,000 IU) |
Do I need to be careful with the vitamin K2 products if I take medication?
Yes. If you use anticoagulants, often called blood thinners, such as coumarin derivatives, speak to your doctor or pharmacist before starting a product with vitamin K. Vitamin K can affect how those medicines work. This applies to combinations such as Vitamin D3 & K2 Forte and to bone formulas that include K2 as menaquinone-7. Product labels carry the same warning, and it is worth taking seriously rather than treating as small print.
What are the cPNI products, and can I simply order them myself?
The cPNI products are a separate part of the range, developed for certified PNI therapists rather than for general use. They are usually dosed around a personal plan, with specific timing instructions, and several carry restrictions: some are not for use during pregnancy or breastfeeding, and formulas with St John's wort can interfere with medicines such as antidepressants and sedatives. You can buy them, but the brand itself advises getting advice from a certified PNI therapist first. For everyday use, the general range is the sensible starting point.
