Teresa Feix is 30 years old and lives in beautiful Liezen in Styria. In addition to her job in accounting, competitive sport dominates her everyday life. She loves being outdoors in nature most of all – whether on skis, on the bike or on foot. The opportunities for sport in the mountains are wonderfully varied for her.
Our beautiful landscape, the calm and freedom – that is what gives me a sense of slowing down, joy and gratitude. I really enjoy repeatedly coming up against new challenges, pushing my body and exploring my limits.
From Mountain-Bike Marathon to Ski Mountaineering
Until November 2020, Teresa competed in all her races at mountain-bike marathon events. That same year she discovered ski mountaineering – and it immediately became one of her greatest passions. She was admitted to the Styrian regional squad and has been coached by professional trainers ever since.
Training on skis on the glacier begins as early as October. To be perfectly prepared for the ski-mountaineering races in the vertical, individual and sprint disciplines, she combines long base sessions with interval training. Until the start of spring, Teresa spends most of her time around Schladming, which offers the best conditions for this. In summer, long base sessions on the road and mountain bike as well as intervals are on the plan – and she also trains on roller skis in the classic style.
Everyday Training and PANACEO
In training, for recovery and in everyday life, Teresa uses PANACEO products. Before taking the supplements and certified medical devices, she often struggled with stomach and gut problems during physical exertion.
Since I fuel myself during my training sessions and competitions – both in ski mountaineering and on the bike – with PANACEO Energy ISO² and PANACEO Sport Pro-Support powder, I have got my stomach and gut problems under control.
According to the manufacturer, the volcanic mineral PMA-Zeolite it contains supports a healthy, strong intestinal wall. Teresa has found the best possible fuelling for herself in endurance sport with these products – and also attributes an increase in performance to them.
Teresa's Intake and Recommendation
To be able to deliver my physical performance, I mix 2–4 scoops of PANACEO Energy ISO² and 1–2 portion scoops of PANACEO Sport Pro-Support powder with water into my PANACEO bottles. If I need an extra energy kick, I add the specified daily dose of PANACEO Energy BOOST³ powder. The PANACEO Sport Pro-Support powder in particular helps me protect my stomach and intestinal wall. Since the stomach and gut are heavily stressed during physical activity, I recommend these products to every athlete – in competitive as well as recreational sport.
For the recovery of her muscles after exertion, Teresa reaches for PANACEO AMINO8 in powder or capsule form. Her daily routine also includes the supplements Green Health Immun-Aktiv Plus and Green Health Magnesium & Calcium in capsule form.

PANACEO ISO² DRINK
Isotonic drink powder for carbohydrate fuelling during long endurance sessions and competitions.
