Frequently asked questions
Subscriptions, returns, rewards, choosing products, analysis and production.
Orders via the MKN webshop are sold and administratively handled by Cosmotrend BV. Payments run through Stripe.
Choose your product or bundle, add it to your basket and complete checkout. An account is not required to order, but it is to manage your points and your subscription.
After checkout you receive a confirmation with an overview of your order.
Payment runs through Stripe. Depending on your country, Bancontact, iDEAL, Visa, Mastercard, American Express, Apple Pay and Google Pay are among the options.
Which methods apply to you is shown at checkout.
Yes. An invoice is drawn up for every order and sent by e-mail.
At checkout you indicate whether you order as a private individual or as a business. For a business order you enter your VAT number; the invoice is then made out in the company’s name.
Yes. The prices shown include VAT. In Belgium the reduced rate of 6 % applies to food supplements. Shipping costs are calculated separately and visible before payment.
Companies outside Belgium can enter their VAT number at checkout. After verification, VAT is reverse-charged and the invoice shows no VAT. Without a valid and verifiable number, Belgian VAT is charged.
Payment details are processed directly by Stripe. Cosmotrend BV neither receives nor stores card details.
Shipping is from Belgium. Cosmotrend BV works with a fixed carrier partner.
Orders are generally dispatched within one working day of payment being received. Orders placed at the weekend or on a public holiday are processed the next working day.
Delivery time depends on the country of destination. For Belgium, the Netherlands, Luxembourg, France and Germany that is usually one working day after dispatch; elsewhere in Europe two to three working days; outside Europe three to four working days.
These times are indicative estimates from the carrier and do not count as a guaranteed delivery date.
To all countries of the European Union, and in addition to the United Kingdom, Switzerland, Norway, the United States and Canada.
For delivery outside the European Union, import duties, taxes or administrative charges may apply. These are borne by the recipient.
The shipping rate depends on the zone. Within the European Union a free-shipping threshold applies per zone.
The exact amount is shown in the basket before payment.
As soon as the shipment is handed to the carrier you receive an e-mail with a track & trace number. If you have an account, the tracking number is available there too.
Report this within two months of delivery via the contact form, with your order number and clear photos of the packaging and contents.
Cosmotrend BV takes the case up with the carrier and arranges a suitable solution.
Choose a formula or bundle and set the term yourself. Cosmotrend BV handles the sale, the deliveries and the payments. You pay per delivery; the discount is tied to the chosen term.
Have a question about your running subscription? Do let us know via the contact form. We look at what is possible together with you.
You can choose from four terms:
The discount applies to all deliveries within the chosen term.
Yes. You can stop at any time, provided you one month in advance report it. The current month is still delivered and charged; after that the subscription stops.
Report your cancellation via the contact form, or by e-mail to customerservice@mykeynutrients.com. State your name and order number, and we confirm your cancellation in writing.
The discount belongs to the term you choose. If you stop earlier than agreed, we recalculate the discount to the term you actually took and settle the difference on your final invoice. For example: take twelve months at −20 % and stop after four deliveries, and those four deliveries are charged at the three-month rate (−12.5 %).
Get in touch with us. Postponing a delivery, switching formula within the same family or changing your address we arrange in consultation. Preferably report it well before your next delivery, so we can still hold it back.
The subscription ends at the close of the agreed term. It is not renewed automatically.
Want to carry on? Then you choose a new term yourself or place a one-off order.
Orders via the MKN webshop are sold and administratively handled by Cosmotrend BV.
Yes. You can return your order within the statutory withdrawal period provided the products are unused and the original seal is completely intact.
Report your return first via the page Right of withdrawal. You don’t have to give a reason.
The refund is made no later than fourteen days after we receive your withdrawal.
Cosmotrend BV may withhold the refund until the products are received or until you have provided valid proof of dispatch.
The purchase amount and the cost of standard outbound delivery are refunded via the same payment method. The direct costs of the return shipment are for the customer, except where a wrong or damaged product was delivered.
A food supplement whose seal has been broken cannot be resold for reasons of health protection and hygiene. For such products the right of withdrawal lapses once the seal is broken.
So always check the product name, variant and packaging before opening.
Report this as soon as possible via the contact form and state your order number. In case of damage, preferably add a few clear photos.
Cosmotrend BV arranges a suitable solution and, where a return is needed, covers the return costs.
With the MKN Rewards programme you automatically collect points on eligible purchases. The programme is managed by Cosmotrend BV.
For every two euros you spend, you receive one point.
One point represents € 0.10 in shop credit. That corresponds to 5 % of the eligible purchase amount.
The points are added to your account. You do not need to request them separately.
Yes. Loyalty points and subscription discount are independent of each other. You keep earning points on the product amount actually paid.
You can redeem points from 100 points, worth € 10 in shop credit.
At checkout you choose how many available points you want to use. The shop credit is then deducted from the eligible amount.
Each point stays valid for one year from the date it was awarded.
In your account you see how many points you have and when they expire.
When you refer someone via the official referral programme, you can both receive a reward.
The precise terms and validity rules are set out on the Rewards page.
Points for your own purchase appear automatically in your account once the order is finally processed.
A referral reward is granted as soon as the referred customer’s order meets the conditions and is finally processed.
There are three ways to choose:
Bottle-on-the-Go
Functional drink concepts for daily use, with different accents within the gut–organ axes and longevity.
Biotics
Targeted formulas for food sensitivities, digestive comfort and moments when your food tolerance is extra challenged.
X-Fusion
Formulas in which ingredients are deliberately combined around one clear goal.
Fraction Series
Separate nutritional fractions and macronutrients that can be built up step by step and combined in a targeted way.
ComboRoll
Composite combinations for supporting selected pathways, including as targeted optimisation after an analysis.
HERO Collection
Practical nutritional support for moments when food-first is temporarily hard to apply, for example while travelling or on a busy schedule.
Gutletic
Gut-friendly sports nutrition for use before, during or after exertion, depending on the specific formula.
Growth Series
Phased sports nutrition according to training build-up, sports discipline and the relevant biomotor qualities.
In many cases that is possible, but not every combination is automatically needed or suitable.
Always check:
The α, β and γ variants of one product are generally alternatives or consecutive steps. They are not used together as standard.
Are you using medicines, pregnant or breastfeeding, or do you have a medical condition? Then discuss combinations with your doctor or pharmacist first.
That differs per formula. So always follow the instructions on the label or the personal protocol.
Some products are used with a meal, digestive enzymes are taken around the meal according to their specific instructions, and sports products can be used before, during or after exertion.
So there is no general intake moment that applies to the whole MKN range.
That depends on the formula, the purpose of use and your personal situation.
With a temporarily much-changed stool, such as diarrhoea, or when using digestive enzymes, you can sometimes notice your response more quickly. For formulas aimed at nutritional status, build-up or support over a longer period, more time is usually needed.
That too is product-specific. Some formulas are used briefly and situationally; others are part of a programme spanning several weeks or months.
Follow the recommended duration of use on the label, in the product advice or in your personal protocol. Using it longer is not automatically better.
No. You can choose a formula based on the purpose of use, the product information or Find your formula.
An analysis becomes interesting when you want to choose less generally and more on the basis of your personal biology. It can help set priorities, but it is not a compulsory gateway to MKN.
Depending on the analysis chosen, My InnerSelfie brings together several layers of biological information. These may include genetic variants, the microbiome, relevant biomarkers and personal context.
My Key Nutrients is the nutrition and supplement range. Information from an analysis can be used to choose and combine more precisely within that range.
So the analysis provides insight; MKN can be one part of the practical nutrition strategy that follows.
Yes. You can start with a general or goal-oriented formula and decide later to personalise further.
An analysis is a snapshot or baseline measurement. It does not simply prove that an earlier product choice was “right” or “wrong”, but it can show which points of attention are relevant at that moment.
Yes. CosmoPulse is the decision and follow-up environment for sport. It brings together various sporting and biological data and translates them into usable information for athlete and staff.
Where relevant, MKN formulas can form part of an individual nutrition or supplement protocol. The selection is made according to the sport, the training phase, the load and the personal profile.
An analysis can be relevant for those who:
An analysis is not a medical diagnosis. Persistent, severe or unexplained complaints always belong with a doctor first.
MKN is sold by Cosmotrend BV and produced by Cosmofarma BV. Both companies have their own legal and operational role.
All production-related certificates, accreditations, audits and quality claims on this page relate exclusively to Cosmofarma BV and to the scope stated in the document concerned.
The MKN products are produced in Belgium by Cosmofarma BV, at the production site in Eeklo.
Cosmotrend BV is responsible for commercialisation, webshop sales, payment, delivery and customer service.
Cosmofarma BV carries out production. Depending on the product this includes weighing, mixing, filling, packaging and checking according to established production and quality procedures.
Trace
Raw materials, suppliers, production data and finished products are linked to a batch number and a documented file.
Test
Checks are carried out according to product specifications and a risk-based control plan. Which analyses are needed depends on the raw material, the product form, the composition and the assessed risk.
Trust
A production batch is released only after the required checks have been carried out and the accompanying documents assessed.
Every production batch is checked according to the applicable control plan. That does not mean the exact same full analysis package is automatically run on every batch.
Depending on the product and the risk analysis, checks may cover identity, composition, microbiology, purity or contaminants such as heavy metals, among others.
Cosmofarma carries out internal checks and, where the control plan or the regulations require it, has analyses performed by an external laboratory.
Ask it via the contact form. We reply within two working days.
