Guest Expert: Dr. Colleen Hartwick, Naturopathic Doctor

In recognition of Men’s Health Awareness Month, this compelling episode of The Tonic dives deep into a growing—and frequently overlooked health crisis: low testosterone in younger men. Hosted on Zoomer Radio and featuring special guest Dr. Colleen Hartwick, a leading naturopathic doctor specializing in male hormonal health, this conversation brings clarity to a complex issue affecting millions.

Once thought to be an age-related concern, low testosterone is now being seen in men in their 20s, 30s, and 40s. These are levels previously seen in 60 and 70 year olds. Dr. Hartwick shares her clinical insights into why this trend is accelerating—and what natural and lifestyle-based strategies can help correct the imbalance. She enlighten listeners on how sex hormones affect neurotransmitters such as dopamine which lend motivation and vigour to a man’s constitution.

🎯 Key Topics Covered:

• The biological role of testosterone in libido, energy, mental health, muscle mass, and metabolism
• The surprising link between testosterone and dopamine, motivation, and mental well-being
• Common causes of low testosterone in younger men, including:
• Chronic stress
• Poor sleep and sleep apnea
• Sedentary lifestyles
• Excess body fat and aromatization, the process where white body fat turns testosterone into estrogen.
• Endocrine-disrupting toxins in plastics and personal care products, even fragrances can contain hormone disrupting compounds.
• Alcohol overuse and dietary deficiencies

Dr. Hartwick breaks down the most reliable testing methods, including total testosterone, free testosterone, sex hormone binding globulin (SHBG), and cortisol levels—to help men get a clearer picture of what’s going on hormonally. She also highlights common symptoms men shouldn’t ignore, low libido, fatigue, loss of muscle mass, belly fat gain, lack of concentration, and depression-like mood drops. She stresses the fact there is a natural age related decline in testosterone measuring approximately 1% annually.

🏋️‍♂️ Natural Ways to Boost Testosterone:

• Prioritize sleep—your hormone cycle depends on it
• Lift weights & strength train—build muscle to trigger hormone release
• Engage in friendly competition—even a game night or debate can spark hormonal upticks
• Reduce alcohol and avoid xenoestrogens in plastics and body care
• Eat a testosterone-boosting diet:
• Healthy fats: avocado, olive oil, nuts & seeds
• Crucial minerals: zinc (pumpkin seeds, oysters), magnesium (dark chocolate), Vitamin D
• Cruciferous vegetables: broccoli, kale, cauliflower to balance estrogen
• Supplement strategically under professional guidance, with:
• Zinc, Vitamin D, Magnesium, Omega-3s
• Herbal adaptogens like ashwagandha, rhodiola, fenugreek, and Tongkat Ali

✅ First Steps If You Suspect Low Testosterone:

Dr. Hartwick emphasizes that if you suspect your testosterone is low, the first step is getting tested. SHBG is among the most important markers to get tested as it tends to gobble up free testosterone. In the meantime, two key changes you can make today are: get better sleep and strength training, lift something heavy! Moderation of alcohol consumption is also suggested as it contributes to channeling testosterone down an estrogen pathway. She also touches on the importance of incorporating healthy fats into your diet to supply testosterone building blocks.

🔍 Why This Episode Matters:

Understanding the Real Causes Behind Skin Conditions: Insights from Dr. Dasha Leneva

In this insightful episode of The Tonic, naturopathic doctor Dr. Dasha Leneva joins host Jamie to bust popular skincare myths and share evidence-based strategies for managing skin conditions like acne, eczema, and psoriasis. This must-listen conversation blends naturopathic insight with practical advice for anyone seeking healthier skin from the inside out.

🔍 Is drinking more water the key to glowing skin?

Dr. Leneva addresses this persistent myth by citing research that shows hydration does help reduce trans-epidermal water loss but has minimal effect on acne and eczema. These benefits do tend to tap out at approximately 2 litres per day. While staying hydrated is important, overhydration won't be your miracle cure. She emphasizes that skin reflects internal health, and treating symptoms externally isn't enough without addressing underlying causes.

👩‍⚕️ Beyond Teen Acne: The Role of Hormones and Stress

Think acne is just a teenage issue? Think again. Dr. Leneva highlights that over 50% of adult women and 40% of adult men still suffer from breakouts well past the age of 25. The culprits? Often chronic stress, insulin resistance, and hormonal imbalances. She explains how high androgen levels (like testosterone and DHT) are tied to adult acne, and how identifying hormonal triggers is instrumental for long-term skin clarity.

🌿 Managing Eczema and Psoriasis Naturally

From vitamin D3 to omega-3s and targeted probiotics, Dr. Leneva discusses the multifactorial nature of eczema and psoriasis. While these conditions may have a genetic component (such as a filaggrin gene deficiency) which disrupts the skin barrier, she shares a hopeful message: symptoms can be managed effectively with the right combination of gut health, moisturization, and lifestyle changes. She stresses timing moisturization following a shower as a wise protocol. Even cold plunges and saltwater treatments, trending on social media, have their place—but only for the right skin types. Dasha shares how salt water may help some skin conditions but the lowering of stress during a seaside vacation likely plays a part. They also touch on the effects of chlorine as an irritant.

🧘 Skin and Stress: A Two-Way Street

Dr. Leneva makes a powerful case for the mind-skin connection. Stress hormones like cortisol increase oil production, break down the skin barrier, and trigger inflammation. But she doesn't stop at the science—she offers actionable tools like cognitive behavioral therapy (CBT), mindfulness, and adaptogenic herbs (magnesium, valerian, passionflower) to help patients manage emotional triggers which can manifest physically on their skin.

🔥 Saunas, Sea Salt & Skin Detox – What Works and What Doesn’t

Do saunas actually “detox” your skin? What about infrared vs. traditional heat? Dr. Leneva explains how excessive sweating can sometimes make acne worse and how saunas can flare sensitive conditions like eczema and rosacea. Sea salt treatments like Dead Sea soaks may soothe mild eczema but aren’t cures. Ultimately, balance and consistency are better long term than extremes.

🧴 Minimalism in Skincare

Her final take-home truth? You don't need a 12-step skincare routine. Overdoing it can damage your skin. Instead, focus on simple, targeted routines backed by science—and always listen to what your skin is trying to communicate. "Your skin isn’t betraying you," she says. "It’s giving you clues—learn to decode them." Hopefully, these tips will help you decode your particular situation so you can address the cause and not merely the symptoms of your skin concerns.

Whether you're struggling with skin conditions or simply overwhelmed by conflicting advice, this episode offers clarity, compassion, and holistic strategies to help you glow from the inside and out.

IBS & Stress: The Gut-Brain Connection You Need to Understand

IBS—irritable bowel syndrome—is one of the most common yet misunderstood digestive issues affecting millions of people worldwide. In this eye-opening episode of The Tonic, host Jamie Bussin welcomes back naturopathic doctor Colleen Hartwick to explore the real causes of IBS and what you can do about it—starting today.

IBS is no longer a mystery illness. Once referred to by names like “mucous colitis,” IBS is now understood to be a complex gut-brain axis disorder. She also refers to its recognition in the Merck Manual, the diagnostic tool used by the medical profession, as being updated as a disorder of the gut-brain axis. Dr. Hartwick explains how the body’s nervous system—especially the vagus nerve—plays a pivotal role in either calming digestion or triggering symptoms. When you're stressed, the body flips into “fight or flight” mode, shutting down digestion, disrupting enzyme production, and triggering constipation, diarrhea, gas, and bloating. The body prioritizes survival over digestion when exposed to stress, which leads to many of these symptoms.

But what actually causes IBS flare-ups? According to Dr. Hartwick, common culprits include:

• Dietary triggers like dairy, gluten, and high-FODMAP foods (e.g., onions, garlic, apples).
• Artificial sweeteners including aspartame and sucralose, which disrupt gut bacteria, and the microbiome.
• Hormonal shifts (especially in women during menstruation).
• Sleep deprivation and dehydration, which amplify gut sensitivity.

Listeners will learn practical tips to take control of IBS symptoms. Dr. Hartwick suggests starting with a food and symptom journal, noting bowel movements, stress levels, sleep patterns, and diet to uncover individual triggers. This simple, personalized approach empowers people to identify patterns and reclaim control of their gut health. This can help determine “cause and effect” trends in gut health.

She also covers natural remedies for IBS, including:

• Magnesium Bisglycinate: Ideal for stress-related IBS and better sleep.
• Magnesium Citrate: A gentle, natural support for constipation relief, she also discusses the role of soluble fibre and adequate hydration.
• L-Theanine: A calming amino acid that boosts GABA levels in the brain, an excellent option for stress related IBS.
• L-Glutamine: Essential for healing a leaky or inflamed gut, especially after diarrhea.
• Probiotics: Focused on diverse strains featuring Lactobacillus and Bifidobacterium to support microbiome balance.
• Digestive enzymes and bitters to enhance food breakdown and reduce bloating.

The podcast also dives into lifestyle interventions which can help regulate the nervous system and ease IBS symptoms, such as:

• Creating a consistent daily routine (sleep, meals, activity).
• Practicing mindfulness and breathing to mange stress.
• Identifying de-stress rituals—from walking to rock climbing—that keep you in the moment. Avoid stressing about the future or ruminating about the past.
• Staying hydrated to support motility and stool formation.

This conversation goes beyond surface-level solutions. It’s a deeply informed, science-based look at how IBS is connected to your emotions, habits, hormones, and gut microbiome—and what you can do holistically to feel better.

Whether you're newly diagnosed, dealing with unexplained digestive issues, or searching for natural solutions that work, this episode is a must-listen. Dr. Hartwick’s insights are clear, compassionate, informative, and grounded in naturopathic clinical experience.
