Every body is unique. That’s why we don’t all need the same. Discover how personalized nutrition and supplementation are your allies for your wellbeing.

As time goes by, our body, our needs, and our preferences change.

This is because we keep experiencing and discovering more about ourselves, and with these changes, our nutritional needs change too!

Personalized nutrition gives us a snapshot of how our body is doing, what it needs to face the stage we’re in, and how to make wise decisions to optimize our wellbeing.

What is personalized nutrition and why is it important?

Personalized nutrition is a nutritional strategy based on your personal characteristics: age, lifestyle, digestive health, physical activity, or even genetics.

The goal is to help you feel better, have more energy, strengthen your defenses, and prevent the natural wear and tear of the body.

Benefits of personalized nutrition

Personalized nutrition is key to maintaining a strong immune system.
Especially when our body undergoes changes — for example, with age, when starting a new routine, training, or lifestyle adjustments — both women and men experience changes in metabolism, hormonal balance, gut health, etc.

By adjusting our nutrition, we help our body adapt better to new routines or daily needs, staying strong and ready for whatever comes.

Proper nutrition also supports our immune system, and with a strong shield, nothing can stop us!

How to put personalized nutrition into practice?

To put it into practice, the best thing is to listen to your body:

• How’s your energy?
• Do you catch colds easily?
• Are your digestion and concentration at their best?
• How would you assess your stress levels?
  

Evaluate your goals and plan of action:

Choose which areas you need to strengthen or want to pay more attention to, and create your strategy or action plan, knowing what’s important and how to support yourself through healthy habits, including nutrition and hydration, regular physical activity, supplementation, etc.

For example, here are a few steps you can take depending on your wellness goals:

• Strengthen your immune system:

  If you feel that your goal is to support the normal functioning of your immune system, then an action plan could be to review your diet and check whether it’s rich in nutrients like vitamin C, D, zinc, selenium, iron, etc.

Vitamin C (sources: citrus fruits, fresh vegetables), vitamin D (mainly found in oily fish and sun exposure), zinc (in shellfish, meat, legumes, nuts), and selenium (in shellfish, fish, eggs, whole grains), all contribute to the normal function of the immune system.

• Maximize your energy:

  Do you feel like your energy isn’t what it used to be? If you notice fatigue or tiredness, include nutrients like iron, biotin, vitamin C, or B vitamins in your diet.

Iron and biotin contribute to normal energy metabolism.
Additionally, vitamins C, B6, and B12 help reduce tiredness and fatigue.

• Support healthier skin and hair:

  Your skin is your largest organ, and if you want it, along with your hair and even your nails, to look their best, then biotin, selenium, or collagen support are excellent options.

• Improve digestion:

  They say the stomach is the second brain, and sometimes we overload it with stress, rushed eating, or missing nutrients. If this is your focus, consider supporting it with yogurt or probiotics, your gut microbiome will thank you!

Maintaining a balanced and varied diet is essential for well-being. But in some cases, food supplements can help meet nutritional needs when dietary intake is limited.
High-quality supplements with science-backed ingredients can make a big difference!
