Personalized supplement manufacturing: from genetic, blood and questionnaire data to custom vitamin packs

What personalized supplements mean

With a conventional supplement, everyone gets the same thing: one formula, one dosage, one pack. With personalized supplements, the formula is calculated for one individual person. Rather than selecting a matching variant from a range, the amount of each nutrient is determined from that person’s data.

The market uses the term in broader and narrower senses. There are three typical levels:

This chapter is about the third level – personalized supplements in the strict sense, often marketed as custom vitamin packs. It places the highest demands on data interpretation and production, and on your choice of a personalized supplements manufacturer.

The data sources: genes, blood and questionnaire

A personalized formula is only as good as the data it is based on. There are three possible sources, plus basic data about the person:

Genetics act in three ways: a gene variant can block the conversion of a nutrient into its active form, it can make an otherwise beneficial substance unfavorable for that person, or it can raise the amount needed for a nutrient to be effective.

You do not necessarily have to re-test. If usable genetic or blood data already exists, for example at a lab or a testing company, it can be interpreted – see from SNP data to a formula and from lab results to a formula. If it is missing, the analysis can be carried out by the manufacturer: Novogenia is itself a genetic lab and also runs blood analyses.

How a personalized formula is calculated

At Novogenia, seven steps lead from the base recommendation to the final dose of each nutrient:

1. Base recommendation: for every active ingredient, every age and every sex there is a recommended intake, derived from studies and the positions of scientific bodies, with the established reference values (D-A-CH, EFSA) as the frame.
2. Body weight and other factors: a higher body weight moves the formula upwards, in particular for nutrients involved in energy metabolism; a lower body weight moves it downwards. Competitive sport raises the requirement, and age shifts it in both directions.
3. Genetic weighting: where a genetic weakness is present, its effect is weighted using the literature on that specific variant. Maximum genetic risk leads to the maximum dose; a below-average genetic problem leads to a below-average dose.
4. Diet and lifestyle: the questionnaire answers are applied to the same nutrient.
5. Blood values: where a blood value exists, it takes precedence. A measured deficiency sets the nutrient to its maximum dose; a measured excess removes it from the formula entirely.
6. Several areas per nutrient: most nutrients are driven by more than one area of the analysis; the highest resulting requirement counts.
7. Window and ceiling: finally, the calculated requirement is fitted into a fixed dosing window.

This way, each nutrient is dosed individually and to the microgram – with no coarse grid of preset strengths. Two consequences are worth knowing, not least for your communication: a dose cannot be traced back to a single gene, because it results from many genes and other data. And two people can receive the same dose at the upper limit – for entirely different reasons. The full method is described in How a personalized nutrient recipe is calculated.

The dose always stays within fixed limits

Personalization does not mean “as much as possible”. Harmonized EU-wide minimum and maximum amounts for food supplements are foreseen in the EU directive but have never been adopted. A serious manufacturer therefore needs its own transparent rules. At Novogenia, these apply:

• Dosing window: a minimum of about one third and a maximum of about three times the reference intake – with documented exceptions: vitamin D3 and vitamin B12 go above that range; magnesium, zinc, calcium and copper stay below it.
• Ingredients without a reference intake, such as omega-3, coenzyme Q10 or lutein, have a fixed minimum and maximum per ingredient.
• Safety ceiling: for every nutrient with an EFSA tolerable upper intake level, the maximum is at or below that level. National statutory maximum amounts are complied with as well.
• Capping rule: a calculated requirement below the minimum is set to the minimum, one above the maximum is set to the maximum. No value outside the window is ever produced.

All limits per nutrient are listed on our page on micronutrient dosing limits.

What personalization can do – and what it cannot

The individual building blocks of the calculation are scientifically substantiated: the reference values, the literature on each gene variant and EFSA’s safety assessments. For the finished, fully personalized combination product, however, there are no large randomized trials proving a benefit over standardized supplementation. That applies to personalized nutrigenetics as a whole.

For you as a provider, this means: sell personalization as what it is – a transparently calculated, individually dosed formula – and not as a health promise. Health-related marketing claims are only allowed if they are authorized in the EU. Also explain to your customers that their formula will change over time: with age, with new questionnaire or lab results, and with new scientific findings.

Production: one formula per person

The biggest hurdle is not the calculation but the manufacturing. Instead of one batch of identical boxes, there is an individual product for every person. That requires a dosage form that can be combined freely and a production process that reliably assigns each formula to the right person.

• A combinable form: at Novogenia, each nutrient sits in its own Microtransporters, which are put together for each person according to their formula – more on this in our chapter on dosage forms.
• Daily stick packs: each daily serving goes into a white, brand-neutral stick pack with a window. Two lines of text of up to 25 characters each make it personal, for example with the customer’s name.
• Box: the stick packs go into a dispenser box with 30 or 90 daily servings, fully in your design – or, for the pilot, into a plain white box with your brand sticker.
• Reproduction on subscription: the formula is recalculated for every new production run – at least with the current age, and with new questionnaire or blood data where available.
• Shipping: directly to your customers, under your brand.

The business model for partners

A genetic test or a blood analysis is bought once. A personalized supplement is consumed and reordered. That is exactly what makes it attractive for labs, testing companies, practices, platforms and brands: a one-time analysis becomes a lasting customer relationship.

A pilot pays off twice: you see how your target group responds to the offer, and together we learn what monthly customer numbers are realistic.

What you should bring as a partner

• Access to your target group: customers who are willing to share data and sign up for a subscription – from your practice, lab, shop or community, for example.
• Data, or a way to get it: existing genetic or blood data, or the decision to run the analysis through the manufacturer.
• Data protection and consent: genetic data and health data enjoy special protection under the GDPR. Clarify early who processes which data and how consent is obtained.
• Brand and design: logo, colors and copy for the box and inserts – for the pilot, a sticker is enough.
• Sales and customer service: who explains the product, who answers questions about the formula, who manages the subscription?
• Billing: the decision whether you bill customers yourself or billing runs through the manufacturer.
• Responsibility: whoever sells under their own name is responsible for the product, its labeling and its marketing claims.

Checklist before launch

• Your target group and sales channel are clear.
• The data source is decided: genetics, blood, questionnaire or a combination.
• Data protection, consent and the data flow between you and the manufacturer are settled.
• The manufacturer’s dosing rules are documented and make sense to you.
• The packaging for the pilot is chosen, for example a plain white box with your sticker.
• The subscription model and billing are defined.
• Pilot size and criteria for scaling up are agreed.
• Your marketing claims have been reviewed – no health promises.
• The regulatory notification is scheduled.
