The Supplements Worth Packing for Your Next Vacation
Vacation is when your body is asked to do the most with the least support. Different time zones, longer days on your feet, more sun exposure than usual, irregular meals, and sleep that rarely matches your routine. None of this shows up as illness. It shows up as fatigue, dull skin, bloating, and that specific kind of tiredness that a few days at the beach somehow doesn't fix.
This isn't about overpacking your toiletry bag with supplements. It's about understanding which four things your body actually loses faster while traveling, and what's worth carrying because of it.
Electrolytes: Because Water Alone Isn't Hydration
Cabin air during flights typically sits at 10 to 20 percent humidity, compared to the 30 to 60 percent your body is used to on the ground, which accelerates water loss through breathing and skin even before you've landed. On the ground, heat, long walking days, and increased sweat compound it further.
Here's the part that surprises most people: drinking more plain water doesn't fully fix this. Without sodium and potassium, water you drink can pass through your system without being properly retained, leaving you dehydrated despite frequent bathroom breaks. Electrolytes regulate osmolality, the balance between minerals and water in your blood, which is what actually allows your cells to absorb and hold onto fluid rather than flushing it straight through.
A study comparing plain water to an electrolyte beverage during long-haul flights found that those drinking electrolytes maintained a better net fluid balance by the end of the flight, with reduced markers associated with blood thickening from prolonged immobility. This isn't a wellness claim, it's a measurable hydration difference.
Why it matters specifically on vacation: dehydration doesn't just cause thirst. It contributes to headaches, fatigue, and a level of brain fog that can make the first day or two of a trip feel hazier than it should, right when you actually want to be present.
Collagen: Because Vacation Skin Takes More Damage Than You Realise
This is the one most people don't connect to travel, but the mechanism is well documented. Ultraviolet radiation, the kind you're getting significantly more of on vacation, whether you're at the beach, sightseeing, or simply outdoors for longer stretches than usual, triggers the release of enzymes called matrix metalloproteinases, or MMPs, in the skin. These enzymes actively break down collagen, the structural protein responsible for skin firmness and texture.
UVA penetrates deep into the dermis causing oxidative stress and collagen breakdown, while UVB affects the outer skin layers and drives inflammation, and both pathways activate the same collagen-degrading MMP response. Add in long walking days, more makeup wear than your usual routine, sun exposure, and disrupted sleep, and your skin's collagen turnover is genuinely working harder than it does at home.
This doesn't mean a vacation will visibly age your skin. It means the body's natural collagen replenishment is being asked to keep up with more breakdown than usual, for a sustained number of days. Supporting that input, rather than only treating the output with skincare, is the more complete approach.
Magnesium: Because Travel Stress Drains It Faster
Magnesium is involved in over 300 enzymatic reactions in the body, many tied directly to stress response and sleep regulation, and the body uses it up faster under physical and psychological stress, which travel reliably produces, between time zone shifts, packed itineraries, and disrupted routines.
The research on magnesium and sleep quality specifically is well established. Magnesium supplementation has been shown to improve subjective measures of sleep, including how quickly people fall asleep and how efficiently they stay asleep. It also plays a documented role in melatonin synthesis, helping convert the amino acid tryptophan into serotonin and eventually melatonin, the hormone responsible for regulating your sleep-wake cycle, which is exactly the system that gets disrupted across time zones.
There's a second, less talked about reason magnesium matters on vacation: it helps activate the parasympathetic nervous system, the "rest" mode that counters the low-grade cortisol elevation that comes from new environments, navigation stress, and packed schedules, even on a trip you're genuinely enjoying.
Sleep and Digestion Support: Because Your Routine Doesn't Travel With You
Different beds, different time zones, heavier or richer meals than usual, more alcohol than your typical week, and later nights all compound at once on vacation. Sleep becomes lighter and more fragmented just when you need it to recover from a more physically demanding day than your normal routine.
Digestion takes a similar hit. Unfamiliar food, inconsistent meal timing, and travel-related stress are common, well-recognised disruptors of normal digestive rhythm, often showing up as bloating or sluggishness that has nothing to do with what you ate being "wrong," and everything to do with your system being thrown off its usual pattern.
This is where an evening wind-down ritual does double duty, supporting the transition into rest while gently aiding digestion after a day of less predictable eating, rather than relying on either a sleep aid or a digestive aid alone. AKYA's PM Unwind Tea is built around exactly this overlap, a caffeine-free blend of chamomile, lemon balm, lavender, licorice, and peppermint, sipped 30 to 60 minutes before bed. Chamomile and lemon balm support the wind-down into rest, while peppermint and licorice lean into easing digestion after a heavier or later meal than usual, which makes it a fitting fit for the exact pattern most vacation evenings fall into.
Building This Into a Simple Vacation Kit
You don't need to overhaul your suitcase. Four categories, used consistently across the trip, cover what travel specifically depletes:
- Electrolytes during flights and on high-heat, high-activity days
- Collagen daily, to support the structural protein your skin is breaking down faster under increased sun exposure
- Magnesium, ideally in the evening, to support sleep onset and ease travel-related nervous system tension
- An evening tea ritual to wind down and support digestion after a day that didn't follow your normal eating pattern
Where AKYA Fits Into Your Travel Kit
Two of our formulas are built around exactly this gap.
Essential Collagen Formula delivers 5,000mg of Nippi Japanese marine collagen peptides per sachet, Type I and III, alongside Vitamin C as the synthesis cofactor and Hyaluronic Acid for hydration support. It mixes into water in seconds, doesn't alter taste, and travels well as a single daily sachet, making it easy to keep the habit going even when the rest of your routine is in flux. Available in Orange and Mixed Berry.
For the evening, PM Unwind Tea is a caffeine-free infusion of chamomile, lemon balm, lavender, licorice, and peppermint, built specifically to ease the transition from a stimulating day into rest while supporting digestion at the same time. It's designed to be sipped 30 to 60 minutes before bed, especially after a later meal, more screen time, or a fuller day than usual, which is precisely the pattern most vacations fall into.
The takeaway: Vacation doesn't pause what your body needs, it intensifies a few specific demands: hydration, skin resilience, nervous system regulation, and digestive ease. Packing for those four things isn't excessive. It's the difference between coming home rested or coming home needing a few days to recover from your own holiday.
