[Plainspeak](https://www.trendhunter.com/trends/plainspeak), a new [women's supplement brand](https://www.trendhunter.com/trends/selfish-supplements), is employing this strategy as it enters the competitive wellness space, banking on women telling others about its refreshingly simple, once-daily solution with creatine, clear whey protein and more in a lemonade-like format. On Instagram, Plainspeak encourages newcomers to send them a DM for a sample, and they'll receive a colorful mailer with a scan-to-buy QR code for its Strength Water designed to replace five key daily supplements. As it builds its brand in public, Plainspeak's sampling strategy means that it currently has the capacity to engage with every person and talk to them about their experience with the product. ## Trend Insights (Trend Hunter) - Score: 5.1/10 - Popularity: 27% | Activity: 43% | Freshness: 83% - Audience gender: 10% men, 90% women - Primary generations: Millennial, Gen X - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Marketing](https://www.trendhunter.com/marketing) > [Interactive](https://www.trendhunter.com/interactive) ## Key Themes ### Why This Trend Is Growing - **Mail-order Sampling:** Physical trial kits create a tactile discovery channel for crowded wellness brands seeking lower-friction customer acquisition beyond rising digital ad costs. - **Scan-to-buy Packaging:** QR-enabled mailers turn product samples into measurable commerce touchpoints that connect offline experience with immediate online conversion. - **All-in-one Supplements:** Simplified daily formulations reflect consumer demand for streamlined wellness routines that replace multiple products with one functional format. ### Industries Being Reshaped - **Wellness Supplements:** Ingredient-stacked drink mixes signal room for differentiated formats that combine convenience, efficacy and lifestyle branding. - **Direct-to-consumer Marketing:** Sample-led outreach offers emerging brands a more personal acquisition model built around conversation, feedback and organic advocacy. - **Functional Beverages:** Lemonade-like supplement drinks blur boundaries between hydration, nutrition and performance support for consumers seeking approachable health products. ## Related on Trend Hunter - [5-in-1 Supplement Drinks](https://www.trendhunter.com/trends/plainspeak.md) - [Matcha-Infused Protein Supplements](https://www.trendhunter.com/trends/fayn-allwhey-protein-matcha.md) - [Triple-Benefit Digestion Supplements](https://www.trendhunter.com/trends/protein-ocean-gi.md) - [Combinational Creatine Supplements](https://www.trendhunter.com/trends/titan-nutrition-creatine-hydration.md) - [Muscle Pump Enhancement Supplements](https://www.trendhunter.com/trends/gorilla-ultimate-pump-complex.md) - [Stimulant-Free Citrus Hydration Drinks](https://www.trendhunter.com/trends/hydramax-florida-sunshine.md) - [Potent Liver Detox Supplements](https://www.trendhunter.com/trends/liver-assist-xt-advanced.md) - [Hormonal Protein Health Supplements](https://www.trendhunter.com/trends/gnc-amp-wheybolic-alpha-v2.md) - [Proactive Cycle Supplements](https://www.trendhunter.com/trends/ditto-premenstrual-daily.md)
