Multivitamins is a leader-dominated AI category
Across ChatGPT, Claude, Gemini, Grok and Deepseek, multivitamins is one of the most concentrated AI recommendation categories tracked. Centrum holds 24.7% of brand recommendation share — roughly three times its nearest rival, One A Day at 8.2%, followed by Blackmores (5.4%), Supradyn (4.9%) and Nature Made (4.4%).
At a manufacturer level, Haleon leads the category at 25.1% share, a 9.9-point lead over Bayer. Crucially, that position is almost entirely Centrum-led: Centrum is classified 'Defend' while Multicentrum is 'Review'. The strategy is one brand, one focus — protect and strengthen Centrum's recommendation authority rather than spreading investment.
The core risk: uneven across AI platforms
Centrum's biggest vulnerability is not share — it is platform variance. There is a 59-point spread between its strongest and weakest platform. Centrum is strongest where AI rewards mainstream wellness language (Grok index 125, ChatGPT 115, Gemini 104) and weakest where AI demands ingredient-level proof (Claude 90, Deepseek 66).
Closing the gap is a proof problem, not an awareness problem. Platforms like Deepseek and Claude need stronger technical evidence — bioavailability, ingredient forms, mineral chelates, dietary specificity and third-party testing — to keep recommending Centrum with confidence.
- Grok 125 · ChatGPT 115 · Gemini 104 — reward mainstream wellness language
- Claude 90 · Deepseek 66 — demand ingredient-level technical proof
- Deepseek is the #1 global platform fix
Asia is three different Centrum realities
Centrum's Asian footprint splits into three strategic clusters. Defend leadership in Taiwan (33%), Philippines (32%), Malaysia (31%), Thailand (29%), China (23%) and South Korea (20.4%). Accelerate growth in Vietnam, Indonesia and India, where gaps to the leader are a narrow 3.6–6.4pp. Treat Japan (7%, a 26pp gap) as selective, segment-specific expansion only.
- Defend: Taiwan, Philippines, Malaysia, Thailand, China, South Korea
- Accelerate: Vietnam, Indonesia, India — narrowest gaps, highest upside
- Selective: Japan — structurally weak, senior/nutrient-gap segments only
The phrases AI needs to repeat about Centrum
AI recommendations use direct, consumer-facing language. Centrum should engineer content so winning phrases appear consistently across PDPs, FAQs, pharmacy pages and reviews — while closing the negative drivers that cause technical platforms to hedge.
- Completeness — 'complete daily nutrition', 'fills nutrient gaps'
- Energy & immunity — 'supports immunity', 'helps reduce tiredness'
- Absorption — 'bioavailable forms', 'certified high absorption'
- Verification — 'third-party tested', 'USP verified', 'non-GMO'
- Fix negatives: methylated B12/folate, mineral chelate detail, bioavailability proof
Five moves to stay #1
- Own the mainstream daily wellness answer on every platform
- Add technical proof underneath without losing simplicity
- Fix Deepseek as the #1 platform priority
- Execute the Asia cluster strategy (defend / accelerate / selective)
- Stretch into adjacent segments only where proof aligns (mineral supplements first)
