Willbase Inc. (headquartered in Chuo-ku, Tokyo; President: Hiroki Tanaka), operator of the over-the-counter medicine and supplement selection support site “CureBell,” conducted a survey in May 2026 on continuation and purchasing behavior among 601 supplement and health-food users nationwide.
As a result of the survey, the number-one discontinued ingredient/product was “zinc.” DHC’s multivitamin, which ranked top for cost performance, also appeared as the second-most discontinued product, highlighting a reality where popular, cost-effective products are nevertheless not continued. Conversely, gummy-form supplements rose to second place in repeat-intent rankings, indicating that “ease of taking” is a key to habitual use.
Survey Overview
Method: Internet survey
Target: Men and women with experience using supplements/health foods
Valid responses: 601 (female 450 / male 141 / other 10)
Survey period: May 2026
POINT 1 — Zinc is the top discontinued ingredient: “difficulty swallowing” and “forgetting” hinder continuation
When respondents were asked in a free-response format about products or ingredients they stopped using midway, “zinc” was top with seven mentions. DHC multivitamin (4 mentions) and DHC zinc (3 mentions) brought the total mentions of DHC products to over ten entries on the abandonment list.

* Free responses were normalized and aggregated. Representative discontinuation reasons were extracted from multiple answers.
The largest factors for discontinuation were “difficulty swallowing” and “forgetting to take.” Tablet and capsule shapes and sizes were shown to block sustained use and habit formation.
POINT 2 — DHC multivitamin ranks first for cost performance: verifying the “chosen but not continued” reality with numbers
For “products perceived as good cost performance,” DHC’s multivitamin led with 38 mentions (6.3%). Across all responses, DHC brand products accounted for 31.6%, underscoring a brand strength combining recognition, price, and availability.

However, cross-referencing with the abandonment ranking shows DHC’s cost-performance top products are also present on the discontinuation list. The numbers indicate that “cheap and good” and “able to continue” are different issues; products chosen for cost and recognition may have a lower buying barrier and thus enter a cycle where they are tried but discontinued.

Heme iron shows high CP and low discontinuation, suggesting better continuity characteristics.
POINT 3 — 41% buy in bulk once a month; monthly spending of ¥1,000–3,000 is common — subscription uptake is limited
Monthly spending on supplements was most commonly ¥1,000–3,000 (41%). Purchase frequency was dominated by “once a month” (41%), indicating a style of buying a certain amount in bulk. High-frequency buyers (weekly or more) comprised only 8%, showing that transition to subscriptions or regular deliveries has not progressed significantly.
Bulk buying can result in a feeling of security after purchase and may not lead to daily usage habits. Low purchase frequency and the abandonment reason “forgetting to take” may be two sides of the same problem.
POINT 4 — Gummy supplements rise for “ease of continuation” — UHA dominates taste, repeat intent is 2nd (29 mentions)
When asked which gummy supplements they found tasty, products from UHA Mikakuto gathered 33 mentions and took a commanding lead. Mentions of “gummy supplements (general)” also totaled eight, indicating strong support for the gummy format itself beyond specific brands.

Additionally, for “products respondents want to repeat,” gummy supplements in general (shape specified) ranked second with 29 mentions, following DHC’s multivitamin (37). This number far exceeded DHC’s heme iron and zinc (12 each), and notably the answers specified the gummy “form” rather than a particular brand or ingredient.

* “Gummy supplement,” “UHA gummy supplement,” and “gummy supplement iron” were combined; many answers specified the form.
Combined with the POINT 1 discontinuation reason of “tablets (capsules) being hard to swallow,” gummy formats appear to directly solve that problem. The experience of “tasty and easy to take, therefore continued” may be one answer to the habit-formation challenge that conventional supplements have not solved.
Summary
Underlying reasons for the “bought but not continued” problem include resistance to tablets/capsules, forgetting doses, and weak perceived effects. This survey revealed that even cost-performance leaders like DHC are not always continued, with zinc ranking as the top discontinued ingredient.
While DHC accounted for 31.6% of cost-performance mentions, the presence of the same products in the abandonment ranking suggests that perceived price/quality and the experience of being able to continue are separate considerations. Gummy supplements secured second place (29 mentions) for repeat intent thanks to their unique values of taste and ease of continuation. Going forward, the supplement market will need to emphasize not only ingredient design but also product form and user-experience design as important axes for habit formation and differentiation. Supporting continuity and habit formation through subscription or regular-delivery mechanisms is also an industry-wide challenge given the prevalence of monthly bulk buying.
