NéstorYour Supplements Assistant
Néstor is the biochemist friend who's read the fine print for you: the counterweight to wellness noise. He won't sell you green powders or promise a jar will change your life. He explains why bisglycinate absorbs and oxide doesn't, and why the 12€ one sometimes beats the 80€.
I'll tell you straight, no smoke, with judgment. Néstor.

What they can do for you
- A sensible base. By your goal, your age and what you can invest, with specific forms and the why behind each.
- You learn to read labels. Molecular forms, certifications and ingredient order: you tell value from pretty packaging.
- He finds it and commits. He locates each product and marks which gets his vote, with neutral criteria. You decide.
- Interaction warnings. If something may clash with a medication he says so first and sends you to your doctor. Supplements aren't harmless.
- When evidence is thin. He tells you straight: what we know, what sells hard without proof and what to skip.
- Minds your wallet. Most value for the price: a good generic taken daily beats a luxury premium.
Who it’s for
Néstor is for anyone with a drawer full of magnesium, collagen and multivitamin bottles and no clue which ones do anything. For people who lift and wonder about creatine, who've seen an ad for adaptogens and want a second opinion, or who take medication and don't want to mix blindly. Open him with a half-filled online cart or in front of the pharmacy shelf.
Situations where it helps
Reviewing what you already take
You photograph the four supplements you take every morning. Néstor checks the molecular form of each, the real dose per serving and whether any hides an opaque blend, then tells you which make sense for your goal and which you can drop without missing out. Usually you end up taking fewer things, chosen with more thought.
Three magnesiums, three prices
You have three tabs open with magnesium products at wildly different prices. You paste the links to Néstor, who compares each form, how much elemental magnesium you actually get and how many capsules a day it takes, then tells you which he'd pick and why. The final call is still yours.
When medication is involved
You take a blood thinner and someone suggested omega-3. Before buying, you run it past Néstor. He explains why that combination calls for caution and what to ask, and insists you get it confirmed by your doctor or at the pharmacy first. He won't leave you hanging, but he won't play prescriber either.
Things you can ask Néstor
- I've been vegan for two years. Which form of B12 suits me, and how do I read the dose?
- I'm 50 and want a simple base for more energy without spending over $25 a month.
- This collagen claims to erase wrinkles in a month. Is there evidence, or is it marketing?
- Which seals on a label actually mean something and which are just decoration?
- I do strength training four days a week. Does creatine add anything, and which form should I buy?
How it differs from a generic AI chat
Néstor sells you nothing and won't fill your shelf. He starts from your goal, age and budget, suggests a few things with the exact form and the reason for each, and commits when comparing products. He reads labels from a photo or a link, warns you about possible clashes with medication and tells you straight when something is marketed far beyond what's been proven.
What it doesn’t do
Néstor doesn't prescribe or diagnose deficiencies, and he doesn't stand in for a doctor or pharmacist. On medication, during pregnancy or while nursing, or with a medical condition, get any new supplement cleared by a professional first. Only a blood test shows if you're short of iron or vitamin D. For a severe reaction after taking something, such as trouble breathing, call emergency services.
Frequently asked questions about Néstor
Does he recommend specific products or just ingredients?
Both. Néstor explains which form and dose to look for, finds products that fit and tells you which one he'd choose, without commissions or a pet brand. You always have the final say and, if you take medication, so do your doctor or pharmacist.
What do I do with the supplements already in my cupboard?
Take photos of the labels and send them over. Néstor reviews forms, real doses and blends, then tells you what's worth continuing for your goal, what's expendable and whether anything might interfere with your medication. That way you decide with information, without binning things at random.
Is he useful if I know nothing about chemistry?
Yes. Néstor translates labels into everyday language: why one form absorbs better than another, what each number means and which seal carries weight. The aim is that, over time, you can read a bottle on your own.
