Vitamin D is a fat-soluble vitamin whose oral absorption depends on the presence of fats in the meal. The transdermal route bypasses this problem: D3 is dissolved in a lipid vehicle that crosses the skin directly into circulation. This method provides continuous absorption over 24 hours and ensures a stable blood level, independent of meals.
Yes. Studies estimate that 70 to 80% of French people have insufficient or deficient vitamin D levels, particularly in autumn and winter (insufficient sunshine) and among people with dark skin, seniors and indoor workers. Vitamin D deficiency is associated with weakened immunity, seasonal depression, bone health issues and chronic fatigue.
The Barrière Hello Sunshine patch delivers a daily dose of vitamin D3 (cholecalciferol) suited to maintenance needs. For a confirmed deficiency, higher doses prescribed by a doctor may be necessary. For daily preventive use (autumn and winter), the patch is a simple and effective solution.
The research is substantial: meta-analyses show that vitamin D supplementation reduces symptoms of depression, particularly seasonal affective disorder (SAD) in autumn and winter. D3 is involved in the synthesis of serotonin, the well-being neurotransmitter. Regular intake is advised from October.
In general, supplementation is a priority from September to April in France (insufficient sunshine). In summer, 15-20 minutes of sun exposure per day on arms and legs is enough to maintain adequate levels. If you work indoors, have dark skin or permanently use high SPF, year-round supplementation is recommended after medical advice.
Vitamin D is fat-soluble and can accumulate: do not exceed the recommended dose without medical supervision (a blood test is advised). In cases of hypercalcaemia, sarcoidosis, hypoparathyroidism or active tuberculosis, consult your doctor. May interact with thiazides and certain kidney medications.
