Frequently Asked Questions
SmartStack isn’t about random supplements thrown together. We create intelligent supplement stacks, expertly formulated combinations of nutrients that work better together. Every ingredient has a purpose. Our products are vegan, non-GMO, UK-made, and designed to deliver real results without the fluff.
We prioritise organic, plant-based and naturally sourced ingredients wherever possible. We also work only with trusted suppliers who meet UK and EU quality standards. You won’t find synthetic preservatives or artificial colours in any of our stacks. What are what we like to call “ecoganic”
Yes, many stacks are designed to complement each other (e.g. Lights Out + Calm Commander, or Bloat Buster + Immunity Boost). We recommend checking the label for overlapping ingredients or messaging us for tailoured guidance.
We stand by our stacks. If you’re not completely satisfied, you’re covered by our 100% money-back guarantee. Just email us within 30 days and we’ll make it right—no fuss, no awkward forms.
While our stacks are made with gentle, well-tolerated ingredients, we recommend speaking with a healthcare professional if you’re managing a health condition, taking prescription medication, or have specific dietary needs.
Yes. All SmartStack products are designed for daily use and contain safe, evidence-backed ingredients in carefully balanced doses. We don’t use fillers, synthetic additives, or anything we wouldn’t take ourselves. As always, consult your GP if you’re pregnant, breastfeeding, or on any form of medication.
While many customers report benefits within 7–10 days, most stacks show their full effect after consistent use for 3–4 weeks. Remember… SmartStack supplements are built for sustainable, long-term support, not overnight fixes.
Absolutely. Every SmartStack is 100% vegan-friendly, with no animal-derived ingredients, gelatine capsules or dairy-based fillers. We also ensure all products are non-GMO, gluten-free, and free from common allergens where possible.
Yes! You can save with our Subscribe & Save plan, or choose from curated bundles designed to target multiple needs at once. Flexible, cancel anytime—and always with free UK delivery.
No. We avoid common allergens whenever possible. All SmartStack supplements are gluten-free, dairy-free, and soy-free. If a product does contain a potential allergen, it will be clearly listed on the label.
