Both sit on the sun-drenched Costa Blanca. Both are serious about your health. But choosing between ZEM and SHA is not so much about quality. Both are exceptional. It’s more about knowing which kind of experience and transformation you’re looking for.
Two Clinics 30 Minutes Apart
ZEM Wellness Clinic in Altea and SHA Wellness Clinic in L’Albir are barely 30 minutes apart on Spain’s Mediterranean coast.
They share the same 300 days of sunshine per year, and the same backdrop of mountains meeting sea. They both offer a genuine commitment to integrative health. Yet from the moment you arrive at each, you feel something fundamentally different.
SHA is alive. There are communal tables at dinner. Guests swapping stories between treatments. The hum of a community of people who love both life and their health. It’s the kind of place where you go thinking you’ll focus inward and end up making friends for life.
ZEM is still. Opened in 2025, it was designed from the ground up as a luxury health haven. It’s a space to slow down, to hear yourself think. At ZEM, you let the Mediterranean rhythm do some of the healing. The name of the town says it all: Altea literally refers to longevity. At ZEM, that’s not a marketing line. ZEM philosophy is embedded in everything from the circadian-aligned daily schedule to the organic ingredients grown at their own farm, Finca Althaya, just minutes away.
So this isn’t a question of better or worse. It’s a question of what you need right now.
Integrative vs. Mediterranean Medical Approach
SHA’s method is built on integrative medicine, and a deliberate fusion of Western functional and preventive medicine with Eastern healing traditions. Dr Vicente Mera leads anti-aging and hormonal work. The departments collaborate to build a 360° picture of each guest, and the result is deeply personalised clinical care that manages to feel warm rather than cold.
ZEM’s approach draws from more than 25 medical specialties, which is really a lot. This includes genetics, neurology, sleep medicine, immunology, and more. The results are interpreted through the lens of Mediterranean longevity science. The team includes psychologists (a rare and valuable addition in this space), and the protocols are designed not just to treat or optimise, but to walk alongside you as you reconnect with what actually makes you well.
Brain health is now a real strength at ZEM. Professor Bruno Ribeiro do Couto, the neuropsychologist who ran SHA’s cognitive units in Spain and Mexico, has moved to ZEM, where he is developing its neurocognitive unit. His fields are brain health, sleep and cognitive performance.
It sounds fancy but you get biofeedback-enhanced meditation, neuroplasticity sessions, guided circadian practices, and these sessions are actually awesome. ZEM treats the nervous system as central, not peripheral.
Both ZEM and SHA include psychology, which we consider essential and which remains surprisingly rare in medical wellness. At SHA, it tends to be one powerful consultation within a broader clinical program. At ZEM, the psychology and sexology unit is led by Dr Jessica Castejón, and the psychological and emotional dimensions feel more woven into the daily fabric of your stay.
The Food at ZEM and SHA Wellness Clinic
Food at SHA is medicine, and it’s delicious medicine at that. Three distinct menus give guests real choice. The gourmet SHA menu is for those wanting to eat well without restriction, and the Biolight menu for a lighter, more active detox. The Kushi menu is for those committing to intensive caloric discipline and deep detox. Medicinal teas, miso soup at breakfast, a glass of apple kudzu vinegar before meals … Every detail is therapeutic. Cooking classes help guests take the approach home. But in our experience, making food (and desserts in particular) so enjoyable can also be a little counter-productive for guests looking for lifestyle changes. In particular, the desserts at SHA are so incredibly beautiful and delicious that it may feel really hard to let go of sugar, although these desserts are made without gluten or refined sugar …
Food at ZEM is medicine too, but it speaks a different dialect. Ingredients from Finca Althaya, the clinic’s own organic farm, arrive at your table following the principles of Mediterranean longevity: anti-inflammatory, seasonal, circadian-aligned. The chef creates personalised meals that feel like pleasure. But in our personal experience, ZEM food still includes some foods which can be inflammatory: tomatoes for example.
When we compare both, SHA offers an approach to food which is slightly more medically elaborate than ZEM. If you want structured dietary discipline with clear caloric tiers, SHA gives you a little more control. If you want food that nourishes deeply and makes you rediscover the joy of eating well, ZEM’s farm-to-table approach is extraordinary.
Programs For Your Wellness Objectives
Both SHA and ZEM Wellness Clinic cover the major wellness goals: longevity, detox, weight management, stress and sleep, cognitive health, aesthetics. The difference is in emphasis and level of personalisation.
Overall, you can create any program you need at ZEM Wellness Clinic, because the whole concept is truly flexible.
On the other hand, at SHA Wellness Clinic, you need to choose one of the main programs for your first stay … After that, you can choose the Stay Your Way program (from 4 nights, from 2400€), which lets you completely customise your experience to your goals as well.
So, we can say that both offer programs which are completely tailored to any objective. In practice, when dealing with really complex cases of demanding clients, we have seen slightly more flexibility at ZEM than at SHA.
At SHA:
- SHA’s most medical program is certainly the Advanced Longevity (4 to 14 nights, from 4800€) with 88 biological age markers, NAD therapy, hyperbaric sessions and photobiomodulation.
- The Rebalance & Energize (from 4 nights, from 2500€) is the entry-level program, the natural starting point for most guests at SHA, and the ideal experience for those dealing with burnout or chronic stress.
- Clients also love the Leader’s Health and Performance program (used to be minimum 7 nights, now available from 4 nights, from 3600€). It was built for executives who need to stay sharp under pressure.
At ZEM:
- ZEM’s standout program is the ZEM Prime Longevity (7 or 14 nights, from 7500€), focused on cellular health, biological vitality and measurable wellbeing indicators.
- Clients also really like the new ZEM Neuro Balance (from 6000€): it is ideal for those needing to reset their nervous system and restore sleep and mental clarity.
- The ZEM Detox is a great success as well (from 5500€): a multidimensional recalibration targeting physical, cognitive and emotional wellbeing simultaneously.
- The most affordable way to start is ZEM Essential (3 or 7 nights, from 2500€).
We at Serenity Ways have also curated an exclusive Serenity Ways Reset program at ZEM (5 days, 3200€), combining the best of what ZEM offers (at least from our perspective …) in a thoughtfully designed short-stay format.
The Rooms
The hospitality part of a wellness clinic is rarely the deciding criterion for wellness travellers, but it plays an essential part in how well they regenerate their energy during a retreat.
SHA has the history, and in 2026 it renovated its entry-level suites, which had been a common point of feedback from guests. The new design is genuinely beautiful: the Restyled Deluxe Suite (70m²) starts at 725€/night. The original Deluxe Suite, with bay views, is still available from 650€/night. Higher suite categories were always excellent.
And the addition of Villa Alma, a 995m² private villa across from the main entrance, with private spa, indoor pool, gym and 5 en-suite bedrooms … This makes SHA one of the only medical wellness destinations in the world with true executive group privacy at this level.
ZEM was built from scratch and opened in 2025 with luxury as a non-negotiable. Rooms start at 50m² (the Standard Room, from 550€/night), with outdoor bathtubs and eco-materials. The Feng Shui rooms (55m²) are designed according to harmony principles with panoramic Altea Bay views. The Grand Suite (110m², 2400€/night) has a private massage cabin and chill-out terrace. The Altea Suite (200m², 3200€/night) is among the most spectacular rooms on the Costa Blanca. There are 85 rooms and 10 suites in total at ZEM.
What Does Each Cost?
At both clinics, the program is priced per person and the room per night on top, so a couple pays two programs and one room.
At SHA, the shortest stay is 4 nights. Rebalance & Energize costs 2500€, and a Deluxe Suite adds 650€ per night from November to March, or 750€ from April to October. That puts one person at about 5100€ to 5500€.
At ZEM, ZEM Essential costs 2500€ for 3 nights, and a Standard Room adds 550€ per night, so about 4150€ for one person.
For a longevity program over 7 nights, SHA Advanced Longevity costs 8400€ and ZEM Prime Longevity 7500€, before the room. We can price your exact dates at both and send you the two quotes side by side.
