Travel is one of life's great medicines. It disrupts routine in the best possible way, broadens perspective, and reconnects us with the world beyond our daily lives. But it also places real demands on the body -- disrupted sleep, unfamiliar foods, new pathogens, time zone shifts, and the low-grade stress of logistics can quietly chip away at immune resilience and mental clarity.
As a naturopathic doctor, supporting my patients' immune and nervous systems is central to my clinical work. But it starts with what I do myself. Here are the 12 tools, habits, and supplements I personally rely on to stay well while traveling -- and at home. As always, these reflect my own experience and preferences. I recommend consulting with a qualified provider before beginning any new supplement protocol, as individual needs vary significantly based on health history, lab findings, and current medications.
1. Wellness with Welltory
Heart rate variability (HRV) is one of the most informative and underutilized biometrics available to us. Free apps like Welltory track HRV and provide a real-time snapshot of your productivity, energy, stress resilience, and nervous system state. With this biofeedback, you can start to understand how your body personally responds to various stressors -- jet lag, poor sleep, alcohol, different foods, exercise intensity -- and make smarter decisions accordingly.
I check my HRV score every morning so I have an objective baseline for how to approach the day. One of the most effective techniques I use to immediately improve my score is the 4-7-8 breathing method -- inhale for 4 counts, hold for 7, exhale for 8 -- combined with a mindful focus on what I can control: my actions and my reactions. The stronger our nervous system resilience, the better equipped we are to withstand physical and environmental stressors of all kinds.
2. Activate the Adrenals
Travel -- even enjoyable travel -- is a biological stressor. Change, disrupted sleep, new environments, and irregular schedules all tax the adrenal glands, which play a central role in immune regulation and stress response. Supporting adrenal function while traveling is one of the most overlooked aspects of travel wellness.
For those who prefer a supplement approach, I personally use Adrenal Complex, which includes key immune-supportive nutrients: vitamin A, vitamin C, zinc, B vitamins for energy, and adrenal glandulars. That said, adrenal and immune support is highly individual. I recommend cortisol, DHEA, and nutrient testing before selecting a supplement, so the protocol actually matches your physiology rather than just a label. If you're interested in this kind of evaluation, schedule a consultation [blocked] and we can look at your numbers together.
3. Fastic -- It's Fantastic
When traveling, meal timing is one of the first healthy habits to go. But our metabolism and circadian biology are deeply optimized for regular periods of fasting -- our ancestral physiology simply did not have access to food around the clock. Intermittent fasting supports metabolic function, cognitive clarity, cellular repair, and immune health, and has a growing body of research behind it.
The Fastic app is a practical tool for tracking your fasting window while on the road, holding you accountable without requiring a rigid approach. If you indulge at dinner -- as you absolutely should on vacation -- Fastic can help you calibrate when to eat next to offset the impact. A 16-hour fasting window between your last and first meal of the day is a reasonable general target, which for most people simply means pushing breakfast a few hours later.
4. Sunny Vitamin D3
Vitamin D is foundational to innate immunity -- the body's first line of defense. Despite living in a sun-rich country, the majority of my patients come in deficient, particularly during winter months or after prolonged periods indoors. Optimal levels in my clinical experience sit above 50 ng/mL, and many patients fall well below that.
For travel, I use Nutrabiogenesis' Vitamin D3/K2 -- a potent liquid formula that is easy to pack in a carry-on. The inclusion of vitamin K2 is clinically important: it works synergistically with D3 to direct calcium to the bones rather than soft tissues, supporting bone density without increasing cardiovascular risk. I recommend testing your vitamin D level before supplementing, as the optimal dose varies considerably from person to person.
5. Habitually Hydrate
Dehydration is one of the most common and most overlooked contributors to travel fatigue, headaches, and immune vulnerability. In cooler months or during long flights, thirst signals diminish -- meaning we often need to drink more than we feel like drinking.
I carry a one-liter water bottle as a daily reminder and a sustainability practice. A general starting point for daily intake is half your body weight in ounces, though individual needs vary based on activity, climate, and health status. Not all water sources are equal, and neither are all water bottles. For urban travel, I use the Astrea One filtered stainless steel bottle -- no epoxy liner, which eliminates the risk of BPA leaching. For backcountry or international travel where water quality is uncertain, the Grayl Geopress purification bottle provides reliable filtration against bacteria, protozoa, and particulates.
6. Thieves Essential Oil
One of my favorite travel companions is Thieves essential oil -- a fragrant blend of cinnamon, clove, rosemary, eucalyptus, and lemon with well-documented antimicrobial properties. The name comes from a legend about 15th-century thieves who reportedly protected themselves from plague by wearing a formula of these oils.
I use it as a natural hand sanitizer in place of conventional commercial products, many of which contain synthetic fragrances, triclosan, and other chemicals with questionable effects on immune and hormonal health. Thieves oil is versatile: it can be applied topically as a sanitizer, diffused aromatically to support mood and sinus clarity, or used to freshen a hotel room. As with any essential oil, dilution in a carrier oil is recommended for direct skin application.
7. Maintaining Movement
Regular movement is one of the most evidence-supported immune and mental health interventions we have -- it reduces circulating stress hormones, stimulates endorphin release, supports lymphatic circulation, and improves sleep quality. While traveling, the temptation to skip it is real, but even a 20-minute walk makes a measurable difference.
Beyond the exercise itself, prioritize outdoor movement when possible. Exposure to natural light helps regulate circadian rhythm, supports melatonin production at night, and can significantly reduce jet lag. Fresh air and green environments have their own documented effects on cortisol levels and psychological wellbeing -- benefits no hotel gym can replicate.
8. Systemic Enzymes
Most travelers pack an NSAID -- aspirin, ibuprofen, or naproxen -- for pain and inflammation. The problem is that NSAIDs carry a range of adverse effects with frequent use, including gastrointestinal bleeding, cardiovascular risk, and renal stress. For a natural alternative, I rely on a Systemic Enzyme Complex, a proteolytic enzyme formula derived from sources like bromelain (from pineapple) that supports the body's natural inflammatory resolution processes.
I take it proactively before and after high-output days -- long hikes, strenuous activities, or simply full travel days that leave the body depleted. Typical dosing for me is 2 to 4 tablets depending on the level of support I need, taken away from food. As with any supplement, I recommend discussing it with your provider if you are on blood-thinning medications or have a relevant medical history.
9. Magnesium Bisglycinate
Magnesium is one of the most commonly deficient minerals I see in lab work, and also one of the most clinically useful to replenish. It is involved in over 300 enzymatic processes in the body, including muscle relaxation, nervous system regulation, sleep quality, and bowel motility.
For travel, magnesium bisglycinate is my preferred form -- it is gentle on the gut, highly bioavailable, and particularly effective for muscle recovery after physical activity, difficulty falling asleep, and travel-related constipation (which, for what it is worth, is one of the most common complaints I hear from patients who travel frequently). I recommend starting with a lower dose at home -- around 200mg -- and titrating up gradually to find your personal therapeutic dose, which can range from 400mg to several grams depending on the individual. Complete, regular bowel movements are essential for detoxification and immune health, so this one earns its place in the travel kit.
10. Activated Charcoal
Activated charcoal is one of the most versatile and underrated travel supplements. It is a highly porous, adsorbent material that binds to toxins, gases, and irritants in the gastrointestinal tract and facilitates their elimination. I keep it on hand for food poisoning, traveler's diarrhea, post-indulgence bloating, and excessive alcohol consumption.
One important note: activated charcoal has no selectivity -- it binds to everything, including medications and other supplements. Always take it at least two hours away from any medications or supplements to avoid reducing their absorption. As a bonus travel tip: if your toothpaste gets confiscated at security, activated charcoal powder makes a surprisingly effective -- and whitening -- substitute.
11. Sleep Hygiene
Sleep is the most powerful immune intervention available to us, and it is the first thing to suffer during travel. Protecting sleep quality on the road requires intention. A few principles I follow consistently:
Avoid large meals within 2 to 3 hours of bedtime -- digestion competes with the restorative processes that occur during sleep
Unplug and power down devices at least one hour before bed -- blue light from screens suppresses melatonin and delays sleep onset, and powered devices emit low-level EMF that may affect sleep architecture
Use that hour for reading, a warm bath, or relaxing music -- the nervous system needs a transition period between the stimulation of the day and the stillness of sleep
Expose yourself to natural morning light as early as possible -- this is one of the most effective circadian anchors, especially across time zones
12. Byron White Formulas
For acute and chronic immune challenges, the Byron White Formulas are the most clinically effective herbal immune support I have used in practice and personally. These are sophisticated, practitioner-grade formulas designed to support the immune system's response to a range of acute and chronic pathogens. I travel with A-C and reach for it at the first sign of immune stress.
These formulas are potent and have specific contraindications, so they are not something I recommend self-prescribing. If you are interested in exploring whether they are appropriate for you, contact my office [blocked] and we can discuss your situation.
Where to Find Trusted Supplements
Not all supplement retailers are created equal, and quality control in the supplement industry varies widely. For products I personally trust and recommend, I use Fullscript -- a professional dispensary stocked with practitioner-grade brands, vetted for quality and potency. Feel free to explore it for the products mentioned here and beyond.
