■ Top 5 Noteworthy Ingredients to Combat 'Spring Ailments'
An analysis of iHerb's vast search data from February to March 2026 revealed the 'Ingredient Keyword Ranking' that garnered particular interest this spring. The lineup reflects the real concerns of the new lifestyle season.
■ Decoding 'Problem-Specific, Correct Ingredients' for Women in their 30s and 40s from Data
The top-ranking ingredients are deeply connected to the concerns and lifestyles often experienced by women in their 30s and 40s. This generation, constantly striving in both work and family, seeks to 'efficiently maintain their well-being'. iHerb's search data reveals unique ingredient selection patterns for this age group.
① [For Spring Stress and Accumulated Fatigue] Magnesium
When lifestyle rhythms change with a new season, the quality of rest tends to decline. Magnesium is the ingredient chosen during such times. It is an essential mineral involved in over 300 enzymatic reactions in the body, chosen not for temporary refreshment but for internal conditioning and recovery.
② [For UV Damage and Skin Clarity Care] Astaxanthin × Glutathione
Protecting the skin externally with sunscreen is a given. Beyond that, an increasing number of people are incorporating 'oral antioxidants' before the peak of summer. Astaxanthin, which targets oxidative stress caused by UV rays, and Glutathione, which supports a bright impression from within. Combining these two is a classic pattern for women in their 30s and 40s.
③ [For 'Dullness' from Busyness and Early Aging] Liposomal Vitamin C × Zinc
This generation, with limited time for care, prioritizes the 'absorption efficiency' of ingredients. 'Liposomal' forms, which stay in the body longer than general Vitamin C, are often chosen. Combined with zinc, a source of vitality, the popularity of this minimal-effort approach to well-being is growing.
④ [For Spring Fluctuations and Decreased Vitality] NMN
Spring, with its seasonal changes and the impact of new lifestyles, can easily lead to fluctuations in physical condition. NMN is gaining attention for addressing the vague fatigue and decreased vitality that become more noticeable with age. Known as a precursor to NAD⁺, which is involved in energy metabolism in the body, it is adopted as a care method to maintain a healthy state from within, rather than as a temporary measure.
