- Choosing supplements today is complicated: there's too much information, too much marketing, and very little real medical clarity.
- The right decision doesn't start with the product, but by understanding what your body needs, what your blood tests say, and what stage of life you're in.
- At tres60, we offer the first free medical consultation with specialized doctors, at no cost and with no obligation to purchase.
- Our team covers longevity, sports medicine, gynecology, urology, hormonal health, and clinical nutrition. Each professional addresses what your case requires.
The problem: too much information, too little clarity
Do these questions sound familiar?
- What supplement should I take if they all seem good?
- Which one is best for sleep?
- Do I need to take omega 3 and magnesium?
- Which type of magnesium do I choose from all the existing forms?
- When should I stop taking a supplement?
- What do I do about my chronic inflammation?
- If my family doctor prescribed vitamin D, is the pharmacy one better or one that is better formulated?
- Is everything sold in pharmacies always the best?
If you've ever asked them, you know how frustrating it is to search for clear answers. The internet is full of information, but much of it is marketing disguised as health advice. And when it comes to your body, going in blindly is a risk you shouldn't take.
Why "taking supplements" is not the same as "taking the right ones for you"
Blindly supplementing often leads to three consequences:
- You spend money on products you don't need, while neglecting those that would make a difference in your case.
- You take insufficient doses or poorly absorbed chemical forms, and then conclude that "it doesn't work for you."
- You ignore real problems (iron deficiency, hypothyroidism, hormonal imbalances) that require medical diagnosis, not more capsules.
The difference between a useful supplement and one that provides nothing is almost never in the product itself. It's in whether you're taking it because it's right for you.
How to correctly decide which supplements to take
1. Start by understanding what's happening in your body
Before any ingredient, the first thing is to identify what's happening to you. Fatigue, poor sleep, chronic pain, brain fog, anxiety, hormonal changes, frequent infections... These aren't labels, they're clues. Each one points towards a different type of approach.
2. Review the basics before complicating things
Sleep, diet, light exposure, exercise, hydration, stress management. If the foundation fails, no supplement can compensate. If the foundation is solid, supplements enhance.
3. Rely on data, not intuition
A basic blood test (CBC, ferritin, vitamin D, B12, thyroid profile, lipid profile) rules out the most common causes of fatigue, low mood, or exhaustion. From there, supplementing makes much more sense and has a much greater effect.
4. Choose products with real criteria
A good supplement should have:
- Scientific evidence behind each ingredient.
- Effective, not symbolic, doses.
- Absorbable chemical forms (e.g., bisglycinate for magnesium, not oxide).
- Minimal unnecessary excipients.
- Manufacturing with quality standards (ISO 22000, GMP).
- Traceability and transparency.
- Formulation designed by healthcare professionals, not by marketing departments.
5. Have real support
The most underestimated part, and at the same time, the one that makes the biggest difference. Taking a supplement without understanding why, for how long, and what you should notice is a recipe for abandonment. That's why at tres60 we include a free medical consultation: it's not a complement, it's part of the product.
What sets us apart: the tres60 medical team
The market is full of brands that sell capsules and then forget about you. Others offer an automated questionnaire that only looks like medical advice in a photo. We do it differently.
tres60 is the first brand in Spain with an integrated medical team: professionals with established careers who are behind the formulation, consultation, and follow-up.
First free medical consultation: Dr. Patricia Núñez de Aysa and Dr. Joel Cuesta Gascón
It's not a phone triage or a chatbot. These are doctors who listen, evaluate your case, analyze your global needs, and map out a route to refer you, if necessary, to the exact specialist your situation requires.

- Dr. Joel Cuesta Gascón: Physician expert in sports medicine, rehabilitation, and nutrition.
Gynecology and women's health: Dr. Myrna
Women's health needs doctors who listen and truly understand hormones. Dr. Myrna is our gynecologist, specializing in menopause and Polycystic Ovary Syndrome (PCOS). She addresses cycles and hormonal changes with empathy and the most up-to-date evidence.
Urology, hormones, and performance: Dr. Irene Hernández
Integrated urology is one of the most overlooked areas in daily well-being, especially in men. Dr. Irene Hernández combines urology, sports nutrition, and hormonal health. Her goal: to optimize hormonal balance and vital energy so you perform at your best every day.
Advanced clinical nutrition: Irene Teruel and José Gutiérrez
We don't believe in one-size-fits-all diets. We work with leading nutritionists in their fields:
- Irene Teruel: specialist in inflammatory pathologies and women's health. If your body experiences inflammation, pain, or digestive discomfort, she has the clinical tools to help you.
- José Gutiérrez: expert in body composition and weight loss. Approach based on real metabolic health, without rebound and adapted to your lifestyle.
Why our consultations are free
Because we understand that making the right decision shouldn't depend on how much money you're willing to spend on a private consultation before knowing if you need a supplement. Because real support is not an extra: it's part of doing things right.
And because, if a medical team isn't willing to talk to you before selling you something, perhaps it's not the medical team you need.
How to make the most of this consultation
To make your consultation useful, we recommend arriving with:
- Your main reason (e.g., I sleep poorly, I have low energy, my cycle disrupts me).
- Any recent blood tests you have.
- A list of medications or supplements you are taking.
- Your current routine: rest, diet, physical activity.
- What you've already tried that hasn't worked.
With that, the consultation stops being generic and starts being useful to you.
What we won't do
So you also know what we are not:
- We do not sell capsules to people who don't need them.
- We do not promise miraculous effects.
- We do not replace your primary care physician or your referring specialist.
- We do not treat serious pathologies: we guide, accompany, and refer when necessary.
- We do not use automated questionnaires without medical review.
Health is 360
We don't see you as a knee pain, a dysregulated cycle, or a bad night. We see you as a complete system. Because health is 360: a day, a cycle, a life lived in 360 degrees, and all of them must always be fulfilled.
That's why this blog. That's why the free consultations. Because when you understand how your body works, you have the power to choose how to live.
Conclusion
Choosing the right supplements and who to trust should not be a minefield. It's a decision that deserves judgment, evidence, and real support.
If you have questions about your case, schedule your first free medical consultation with our team. Tell us what's happening and we'll guide you at no cost and with no obligation.
And if you prefer to start by taking a quick test to understand what suits you, you can take our test or write to us directly via WhatsApp.
Frequently asked questions
Is tres60's medical consultation really free?
Yes. The first consultation with Dr. Patricia Núñez de Aysa or Dr. Joel Cuesta Gascón is free, with no cost or purchase obligation. Consultations with other specialists on the team have specific conditions that are explained before scheduling.
How does tres60 differ from other supplement brands?
In three main ways: real medical formulation (not commercial), an integrated clinical team with free consultation, and a global health approach. We don't sell isolated products; we support processes.
Do I need a blood test before the consultation?
It's not essential, but it helps a lot. If you have a recent blood test (within the last year), bring it. If not, we'll guide you on whether it's advisable to get one.
Will you always prescribe something for me?
No. If your case doesn't require supplementation, we'll tell you. And if it needs evaluation by your primary care physician or a specialist, we'll refer you. We don't sell capsules to those who don't need them.
When will I notice the effects of the supplements?
It depends on the active ingredient and the goal. Some effects (muscle relaxation with magnesium, rest with melatonin) are noticed within a few days. Others (hormonal regulation, immune support, sustained energy) require between 2 and 8 weeks of consistent intake. Consistency is the most underestimated factor.
Are your products compatible with medication?
Most are compatible with common medications, but there are exceptions (especially anticoagulants, antidepressants, hormones, thyroid medications). That's why the initial consultation is important: there, we evaluate each case.
Does tres60 replace my primary care physician?
No. We are a complement, not a substitute. If you have a diagnosed condition or chronic medication, your doctor remains the primary reference. We provide guidance on supplementation, habits, and wellness routines.
