Dr. Daniel Yadegar, a cardiologist turned functional medicine expert, has dedicated his career to uncovering the deeper connections between lifestyle, nutrition, and overall well-being. His journey—from working in a cardiac care unit to founding Wellbel, a brand rooted in science-backed wellness—reflects his commitment to treating the whole person, not just isolated conditions.

In this conversation, Dr. Yadegar shares what led him to functional medicine, how addressing the root cause of health issues can lead to profound transformations, and why he believes in the power of high-quality, natural ingredients like those found in LINNÉ. He also offers practical tips for anyone looking to take their first steps toward a healthier lifestyle.

Can you share your journey into functional medicine and what inspired you to pursue this path?

My journey into functional medicine is deeply rooted in both my personal and professional experiences. While practicing as a cardiologist and serving as Associate Director of the Cardiac Care Unit, I realized that traditional medicine often focuses on treating disease after it has already developed, rather than preventing it in the first place. I wanted to go beyond cardiology and address all aspects of a patient’s well-being—nutrition, sleep, stress management, and longevity. That realization led me to complete advanced training in age management and regenerative medicine, which fundamentally changed my approach to healthcare.

Your approach emphasizes treating the root cause of health issues rather than just the symptoms. How did you develop this philosophy, and what impact have you seen it have on your patients?

This philosophy developed over time as I witnessed how interconnected the body truly is. Instead of isolating symptoms and treating them individually, I began focusing on underlying triggers—nutritional deficiencies, inflammation, gut health, environmental toxins, and stress. When you address these core imbalances, patients experience profound transformations. I’ve seen people reverse chronic conditions, regain energy, improve mental clarity, and dramatically enhance their quality of life by getting to the root of their health challenges.

You are the founder of Wellbel, a brand focused on enhancing beauty and wellness from within. Can you share the story behind Wellbel and how it reflects your philosophy on health?

Wellbel was born from the idea that beauty is a reflection of inner health. So many products on the market were filled with synthetic ingredients, unnecessary additives, and short-term fixes. I wanted to create a solution that was clean, effective, and science-backed—one that supported hair, skin, and nail health through essential nutrients that truly nourish the body. Wellbel aligns with my philosophy that when we give the body what it needs, it naturally thrives, and the results are evident not just in how we feel but in how we look.

What role do you believe lifestyle and environmental factors play in overall health, and how can incorporating natural products like LINNÉ support those efforts?

Lifestyle and environment are fundamental to health. Chronic exposure to toxins, poor nutrition, lack of sleep, and high stress levels all contribute to disease and premature aging. One of the best ways to counteract these influences is by using high-quality, natural products—whether it’s in what we eat, what we put on our skin, or how we support our body’s detoxification processes. LINNÉ products are an incredible example of this. Their formulations use botanically sourced, nutrient-dense ingredients that work in harmony with the skin, rather than exposing it to harmful chemicals. Choosing products like these helps reduce our toxic load and supports long-term vitality.

As someone who advocates for a personalized approach to health, what are some practical tips you can offer our readers to better understand their own bodies and unique needs?

1. Listen to your body. Pay attention to how foods, environments, and routines make you feel.

2. Prioritize gut health. The gut is central to overall health—imbalances can affect digestion, immunity, mood, and skin.

3. Use functional lab testing. Instead of guessing, test for nutrient deficiencies, hormone imbalances, and inflammatory markers.

4. Reduce exposure to toxins. Choose clean personal care products, eat organic when possible, and avoid processed foods.

5. Understand your genetics. While lifestyle is key, knowing your genetic predispositions can help you make more informed health choices.

LINNÉ focuses on using botanical ingredients with proven benefits. How do you view the relationship between nature and medicine in your practice?

Nature has always been our most powerful source of medicine. Many modern pharmaceuticals originate from plant compounds, yet synthetic versions often lack the full-spectrum benefits of their natural counterparts. In my practice, I encourage using botanical ingredients wherever possible—whether in nutrition, supplementation, or skincare. LINNÉ products seem to embody this philosophy, offering plant-based formulations that are both gentle and effective, helping to support skin health naturally and sustainably.

With so much information available about wellness, it can be overwhelming to know where to start. What advice would you give to someone looking to take their first steps toward a healthier lifestyle?

Start small and be consistent. Instead of overhauling everything at once, focus on a few foundational habits—eating whole, nutrient-rich foods, prioritizing sleep, reducing stress, and incorporating movement into your day. Swap out conventional personal care products for natural alternatives like LINNÉ. Health is a journey, and the key is to create sustainable habits rather than chase quick fixes.

In your opinion, how does functional medicine bridge the gap between traditional and alternative health approaches?

Functional medicine takes the best from both worlds. It applies the scientific rigor of conventional medicine—advanced lab testing, data-driven diagnostics, and research-backed treatments—while also embracing holistic healing principles, including nutrition, stress management, and environmental health. It’s not about choosing between modern medicine and natural healing; it’s about integrating both for the most effective, individualized approach.

You often share insights on nutrition and its impact on health. Are there any specific foods or supplements you frequently recommend for skin health and vitality?

Absolutely. Some of my top recommendations include:

• Collagen-rich foods (bone broth, wild-caught fish) to support skin elasticity and repair.

• Omega-3 fatty acids (salmon, flaxseeds, walnuts) to reduce inflammation and enhance skin hydration.

• Antioxidant-rich foods (berries, dark chocolate, green tea) to fight oxidative stress.

• Zinc and vitamin C for collagen production and skin healing.

• Probiotics and prebiotics to maintain gut health, which directly impacts skin clarity.

You’ve had the chance to try some of LINNÉ products. How did they fit into your wellness routine, and what impact did you notice from using them?

I’ve been incredibly impressed with LINNÉ products. Their formulations are clean, thoughtfully crafted, and truly effective. What stood out to me was the balance of potent botanicals and ingredients that actually support skin health rather than just masking issues. After incorporating them into my routine, I noticed improved hydration, a more even skin tone, and a general sense of skin resilience—exactly the kind of benefits I look for in products I recommend to my patients.

What’s next for you in your practice and mission to transform healthcare? Are there any projects or initiatives you’re excited about that you can share with us?

I’m constantly working on ways to make functional medicine more accessible to a wider audience. Right now, I’m focused on expanding Wellbel’s product line, and I’m also developing new educational platforms such as my instagram page (@drdanyadegar) to help people take control of their health with science-backed, holistic strategies. My ultimate mission is to bridge the gap between modern medicine and personalized, preventative healthcare, empowering individuals to live healthier, more vibrant lives.
