Contrex is a French brand of natural mineral water sourced from Contrexéville in the Vosges region of northeastern France. It is distinguished by its naturally high mineral content, particularly calcium and magnesium, and has historically positioned itself around health, hydration, and women’s wellbeing [1]. The brand is currently part of Nestlé Waters [1].

The history of contrex spans more than two centuries, originating from the thermal springs of Contrexéville.

The source at Contrexéville gained medical prominence in 1760 when Dr Bagard investigated reports of individuals recovering from kidney stones after consuming the water [2]. In 1774, Dr Thouvenel, physician to Louis XVI, formally recognized the source’s properties and established the first thermal center in the town [2].

Key milestones in the brand’s development include:

• 1760 — The water source at Contrexéville attracts medical attention through Dr Bagard [2].
• 1774 — Dr Thouvenel recognizes the source and establishes the first thermal center [2].
• 1861 — The water is officially recognized as a natural mineral water of public utility.
• 1903 — Health-related properties receive recognition from the French Ministry of Health and the Academy of Medicine.
• 1908 — The first major bottling facility is established.
• 1912 — The Contrexéville thermal center attracts royalty and prominent visitors from across Europe.
• 1976 — The water officially adopts the shorter brand name CONTREX® [2].
• 1992 — Nestlé acquires the Perrier portfolio, integrating contrex into Nestlé Waters France.
• 1997 — PET packaging is introduced.
• 2019 — The brand launches CONTREX® Green, expanding beyond traditional bottled water [2].

Contrex water originates from the Vosges, a mountainous region in northeastern France. Groundwater travels slowly through geological formations beneath the Vosges before reaching the source, naturally acquiring its characteristic mineral composition [3].

The source area is intrinsically linked to the spa town of Contrexéville, whose thermal-water tradition established the region’s reputation long before contrex became a mass-market brand. While closely connected, contrex refers specifically to the commercial water brand, whereas Contrexéville is the municipality and geographical source location.

A defining characteristic of contrex is its relatively high level of mineralization. Published figures indicate the following approximate composition:

• Calcium: 479 mg/L
• Magnesium: 72.2 mg/L
• Sodium: 8 mg/L
• Sulfates: 1,148 mg/L
• Bicarbonates: 378 mg/L
• Dry residue at 180°C: 2,073 mg/L [2]

This profile makes the brand particularly recognizable for its calcium–magnesium balance. Based on current composition, one litre provides approximately 60% of reference calcium intake and more than 19% of reference magnesium intake [2]. As a classified natural mineral water, its mineral composition remains stable over time, and the water is sourced from a specific underground aquifer without chemical treatment [2].

Unlike many mainstream bottled-water brands that focus primarily on thirst or refreshment, contrex emphasizes the body’s mineral needs and personal wellbeing. The brand positions itself as an ally for bodily care, highlighting its calcium and magnesium content [1].

Historically, contrex has employed a female-oriented marketing strategy. Nestlé describes the brand as having been a partner to women for over 60 years. In 2017, it launched “Les Elles by CONTREX®,” a programme designed to support initiatives improving women’s conditions in society [3]. This establishes three primary positioning pillars:

1. Mineral richness
2. Health and personal wellbeing
3. Women’s empowerment and social engagement

Contrex is primarily available as bottled natural mineral water in various sizes, including 1.5 L, 1 L, and 50 cl bottles [2].

Beyond conventional plain mineral water, the brand introduced CONTREX® Green in 2019. This range extends into lightly flavoured and infused beverages, combining fruit flavours and plant infusions with a low-sugar positioning [1].

Contrex is part of Nestlé’s water business. Nestlé’s portfolio of French water brands includes Vittel, Perrier, contrex, and Hépar. The acquisition of the relevant Perrier portfolio in 1992 established what became Nestlé Waters France [3]. Legal information on the contrex website identifies Nestlé Waters Marketing & Distribution as the operating entity [2].

Given that the brand’s identity relies on its natural underground source, environmental protection is integral to its strategy. In 1992, contrex introduced a programme to protect the area surrounding the source from pollution, including restrictions on pesticide use [2]. Current environmental commitments also encompass source protection, sustainable packaging, and carbon-impact reduction [2].

Women’s wellbeing is a central element of the contrex brand identity. Marketing campaigns have historically encouraged women to prioritize self-care and maintain healthy daily habits. This evolved into the Les Elles by CONTREX® programme launched in 2017, which Nestlé describes as a social and sustainable initiative supporting those committed to improving women’s conditions [3]. Consequently, the brand image combines French mineral-water heritage, mineral nutrition, and women’s wellbeing.

The identity of contrex is strongly tied to its French origin and the Vosges landscape. Marketing communications typically follow a narrative linking minerals to bodily health, wellbeing, and everyday hydration. This distinguishes contrex in the bottled-water market; it is marketed not merely as water, but as a naturally mineral-rich product with a specific nutritional profile.

The primary distinction between contrex and standard drinking water lies in mineral composition. While all drinking water contains some minerals, natural mineral waters possess characteristic profiles. Contrex is notable for its high calcium and magnesium levels, with a published dry residue of approximately 2,073 mg/L indicating significant mineralization [2]. This profile also contributes to a distinctive taste compared to low-mineral waters.

As of 2026, contrex continues to emphasize its mineral composition and association with women’s wellbeing. A Nestlé Waters announcement from August 27, 2026, highlighted the importance of calcium and magnesium in women’s nutrition, reinforcing the brand’s positioning as a daily partner for women [3]. The brand is evolving from its historical identity as a French spa water into a broader wellness brand while retaining its core proposition of naturally mineral-rich water from the Vosges.
