Most food supplement brands have 30, 50, even 100 products in their catalogue. We have 3. And it's not because we're lazy (though we don't do 5am cold plunges either). It's because we apply the same brutal filter to our products that you should apply to what you put in your body: Is there robust clinical evidence? At effective doses? Or is it marketing dressed up as science?
At Longevitalis we have a non-negotiable principle: we only launch a product when the ingredients, at the correct doses, have solid studies behind them. We don't iterate quickly. We don't launch 'premium' versions with unicorn powder. We research for months, read meta-analyses until our eyes hurt, and only then manufacture.
In this article, I'll explain why having 3 products is a strategic (and ethical) decision, how we filter ingredients with scientific rigour, and why a small catalogue protects you from market noise. Spoiler: the food supplement industry is designed to confuse you. We do the opposite.
What you'll learn:
- Why a small catalogue signals rigour (not lack of ideas)
- The ingredient filtering process we use (spoiler: brutal)
- How the industry confuses you with evidence-free 'innovations'
- Why we only launch products we use ourselves
- What 'clinically effective dose' means (and why it matters more than price)
What it means to have only 3 products at Longevitalis
Longevitalis has 3 products in its catalogue. Not 30. Not seasonal collections. Not a 'new launch' every quarter to justify marketing campaigns.
Each product addresses a specific biological mechanism related to longevity: deep sleep, inflammatory response, mitochondrial function. We don't make generic multivitamins. We don't make 'energy' without defining what energy means at the cellular level.
This starkly contrasts with the industry model: launch many SKUs, test what sells, discontinue what doesn't work. It's fast fashion applied to your health. We do the opposite: slow research, surgical launch, long-term commitment.
Each formula takes months to develop. We read PubMed studies until 2am. We consult with experts. We test doses. And only when we're confident the product meets our evidence standard do we manufacture it.
How we filter ingredients: the process we use
Here's the filter we apply to every ingredient before considering it for a product. It's the same one you should use before buying any food supplement.
Filter 1: Are there meta-analyses or clinical studies in humans? We don't accept mouse studies or in vitro research. We want randomised controlled trials (RCTs) published in peer-reviewed journals. If an ingredient only has studies in laboratory cells, it's out.
Filter 2: What's the biological mechanism? There has to be a clear explanation of how it works at the cellular level. For example, magnesium glycinate acts on NMDA and GABA-A receptors to promote muscle relaxation and sleep. We don't accept 'improves wellbeing' without a mechanism.
Filter 3: What's the effective dose in studies? Most market products use ridiculously low doses (proprietary, of course) that don't reach therapeutic thresholds. We only use clinical doses: the ones that worked in studies. This increases production costs. We don't care.
Filter 4: Is it safe long-term? We review safety studies, interactions, reported side effects. If there are red flags, even if the ingredient is 'trendy', it doesn't make it.
Filter 5: Would we use it ourselves? This is the final, non-negotiable filter. If Fran (founder) wouldn't take it for 6 months straight, we don't launch it. Simple.
Why the industry confuses you with giant catalogues
The food supplement market is worth $140 billion. And it's designed to confuse you. Here's how:
Tactic 1: 'Exotic' ingredients without evidence. Tibetan ashwagandha powder. Extract from rare Himalayan berries. Sounds premium. No robust studies. But it sells because it seems sophisticated.
Tactic 2: 'Proprietary' doses. When you see 'proprietary blend 500mg' with no breakdown, it signals that individual doses are ridiculously low. It's legal. It's opaque. And it stops you verifying whether you're taking effective doses.
Tactic 3: Launch products every month. If a brand launches 'innovations' constantly, ask yourself: how much time did they dedicate to researching each formula? Serious science doesn't work in 3-week sprints.
Tactic 4: Emotional marketing over science. 'Awaken your inner warrior'. 'Ancestral energy'. Zero biological mechanisms. Lots of storytelling. If a product can't explain how it works at the cellular level, be suspicious.
We do the opposite: small catalogue, complete transparency on ingredients and doses, scientific explanation for every claim. Boring for Instagram. Effective for your biology.
What 'clinically effective dose' means (and why it matters)
This concept is critical and the industry deliberately ignores it. Clinically effective dose = the amount of ingredient used in studies that demonstrated benefits.
Practical example: magnesium glycinate improves sleep quality in studies using 300–500mg of elemental magnesium. If a product has 50mg and says 'contains magnesium', technically it's true. But it's useless.
Another example: glycine promotes deep sleep in studies with 3g (3000mg) before bed. Many products have 100–200mg. It's like putting a drop of petrol in a car and expecting it to start.
At Longevitalis every ingredient is at clinical doses. This makes our products more expensive to produce. But it's the only ethical standard if you take science seriously.
When evaluating a food supplement, ask: what's the dose of each active ingredient? Does it match the dose used in studies? If the brand doesn't specify clearly, it's a sign they probably don't.
The 3 Longevitalis products: what they do and why they exist
Each product in our catalogue exists because we identified a key biological mechanism for longevity that was poorly solved in the market.
LongeviNocturno: food supplement for deep sleep. We combine magnesium glycinate, glycine, taurine, apigenin and L-theanine at clinical doses. Each ingredient has solid meta-analyses showing improvement in sleep latency, N3 phase (deep sleep), and perceived quality. We created it because deep sleep is longevity pillar #1 and most products use melatonin (which creates dependence) or symbolic doses of magnesium. Here's the complete story behind LongeviNocturno.
Product 2 (in development): focused on low-grade chronic inflammatory response. We're researching liposomal curcumin, quercetin and resveratrol. We won't launch until we're certain of bioavailability and effective doses.
Product 3 (in research): mitochondrial optimisation. Exploring NAD+ precursors, PQQ, CoQ10. Same process: months of research before manufacturing.
Notice how we don't launch all 3 at once. We launch when it's ready, not when the marketing calendar says so.
How to choose supplements with scientific rigour
If you're going to buy food supplements (from Longevitalis or anyone else), use this checklist:
1. Is there complete transparency on ingredients and doses? If you don't see exact milligrams of each active ingredient, red flag.
2. Does the brand cite specific studies? Not 'studies show'. We want PubMed IDs, authors, years. If the brand makes claims without references, be suspicious.
3. Do the doses match scientific literature? Search the ingredient on PubMed + 'dosage' or 'clinical trial'. Compare with the product label.
4. Does the price reflect quality? Ingredients at clinical doses cost more. If a product is very cheap, it probably uses symbolic doses or low-bioavailability forms (example: magnesium oxide vs glycinate).
5. Does the brand have clear philosophy or just marketing? Read the 'about us'. If it's all emotional storytelling and zero science, out.
At Longevitalis our principle is simple: we only launch products when the ingredients, at clinically effective doses, have robust evidence. That's why we only have 3 products. Because prioritising quality over quantity means saying no to 97 of every 100 ideas.

Why we'll never launch a product every month
Some brands launch 'innovations' every month. We won't be one of them. Here's why:
Serious science takes time. A robust meta-analysis requires reviewing dozens of studies, assessing methodological quality, identifying biases. That doesn't happen in 3 weeks between Instagram campaigns.
Formulating at clinical doses is expensive. Using 3g of glycine instead of 100mg multiplies the cost by 30. Manufacturing in Spain with rigorous quality controls also costs. We don't compete on price. We compete on effectiveness.
We're not a lifestyle brand. We're a longevity brand backed by science. That means our catalogue grows when evidence justifies it, not when the marketing calendar demands it.
We prefer depth over breadth. Better to have 3 products that work brutally well than 30 that are mediocre. Our goal isn't for you to buy more. It's that the product you buy changes your measurable biology (sleep, inflammation, mitochondrial function).
This philosophy isn't sexy for investors wanting exponential growth. But it's the only ethic if your business is literally people's health.
Our catalogue grows when science justifies it, not when the marketing calendar demands it
Side effects of trusting giant catalogues
Buying from brands with 50+ products has hidden risks:
Risk 1: Ineffective doses. To maintain margins with so many SKUs, brands reduce doses. You end up with products that technically 'contain' ingredients but in useless amounts.
Risk 2: Unstudied interactions. If a brand launches 10 new products a year, did they really study interactions between them? Probably not.
Risk 3: Diluted quality control. The more products you manufacture, the harder it is to maintain consistent standards. More suppliers, more batches, more variables.
Risk 4: Consumer confusion. Do you need the 'Complex Pro' or the 'Advanced Formula' or the 'Premium Blend'? Artificial complexity paralyses you and you end up buying by price or packaging, not evidence.
We eliminate these risks by having 3 products. Each one manufactured in Spain, with brutal quality controls, ISO certifications, and complete traceability. Boring. Effective.
FAQ: Real questions about our philosophy
Why only 3 products if there are many longevity mechanisms?
Because we prioritise depth over breadth. We'd rather have 3 products with brutal evidence than 30 mediocre ones. We'll expand the catalogue when we identify mechanisms poorly solved in the market AND have solid evidence to do it better.
How do I know the doses are really clinical?
Each label specifies exact milligrams per ingredient. You can search the ingredient on PubMed + 'clinical trial dosage' and verify our doses match studies. Example: for magnesium glycinate sleep support we use 400mg elemental magnesium, same as in meta-analyses.
Will you launch more products soon?
Only when they're ready according to our 5-step filter. We have 2 in research (anti-inflammatory, mitochondrial) but we won't give dates. They launch when science justifies it, not when Q3 says so.
Why don't you make generic multivitamins?
Because 80% of the Spanish population don't have multiple deficiencies that justify multivitamins. What they do have is terrible sleep, chronic inflammation and declining mitochondrial function. We solve real problems, not invent needs.
Is it more expensive to manufacture at clinical doses?
Yes. Using 3g of glycine instead of 100mg multiplies the cost of raw material by 30. But it's the only honest way to make food supplements if you take science seriously. We don't compete on price. We compete on effectiveness per milligram.
How do I verify the studies you cite are real?
We cite authors, year and journal on every article. You can search PubMed or Google Scholar. We also use ::study-citation components when highlighting specific findings. If you find we've invented references, we'll refund you and close the company.
Conclusion: fewer products, more science
In a market designed to confuse you with infinite options, having only 3 products is a radical act of clarity.
We don't launch products to justify marketing campaigns. We launch them when we identify a key biological mechanism for longevity that's poorly solved in the market, research for months, and design formulas with verifiable clinical doses.
This means our catalogue grows slowly. But every product we add meets the same brutal standard: robust evidence, effective doses, complete transparency.
If you're looking for 30 options with pretty packaging, we're not your brand. If you're looking for 3 products that really move the needle on your biology, welcome.
Longevity isn't bought from giant catalogues. It's built with informed decisions, repeated over decades. We just manufacture the tools. You decide whether to use them.
