Available in countless varieties tailored to boost specific bodily functions, dietary supplements form a booming market in France worth over €2 billion. A recent study shows 44% of French adults have used them in the past year, with top choices targeting digestion, sleep, and immunity. But when do these concentrated vitamins and minerals become essential?
According to the European directive on these products, dietary supplements are foodstuffs designed to complement a normal diet, providing concentrated sources of nutrients or other substances with nutritional or physiological benefits—alone or combined. France's ANSES agency emphasizes they are not medicines but are strictly regulated at EU and national levels, including authorized ingredients and maximum daily doses.
Consumers seek benefits like better digestion, weight management, immune support, or easing menopause symptoms—often occasionally, though 46% use them year-round per recent market research. Yet, without underlying health issues, a varied, balanced diet meets most nutritional needs. So, when should you consider supplements?
True nutrient deficiencies are rare in developed countries' general populations. Vitamin D stands out as a common exception across all ages, since few foods provide it meaningfully—it's mostly synthesized via UVB sun exposure. In low-sun periods like winter, supplements such as drops or capsules from Granions Laboratory (granions.fr) can be invaluable.
Beyond this widespread issue, certain groups face specific risks. Vegans, excluding all animal products, often lack vitamin B12, crucial for brain and nervous system health.
Diets without fish or seafood may lead to shortfalls in omega-3s like EPA and DHA, vital for brain and eye health. Research in Archives of Ophthalmology links them to preventing age-related macular degeneration (AMD). Those permanently avoiding food groups should get regular blood tests; supplements can correct confirmed deficiencies.
Pregnant women may need iron, calcium, or vitamin B9 (folate) for fetal development—but only under medical advice, as ANSES notes rare cases of neonatal issues like hypercalcaemia or hypothyroidism tied to pregnancy-specific supplements.
Women with heavy periods (menorrhagia) can use iron supplements to prevent anemia. Seniors, with age-related immune vulnerabilities or malnutrition from isolation and poor eating, also benefit—especially in winter.
Before starting any supplement, especially vitamin- or mineral-rich ones, consult a healthcare provider to avoid exceeding safe limits. Ultimately, proven deficiencies alone justify use; supplements never replace a balanced diet, quality sleep, and regular exercise.
