Frequently asked

Questions about this bundle

Can I take this bundle year-round?
Yes — Vitamin C, Vitamin D3, and a daily probiotic are foundational supplements safe for daily, year-round use. The "fall & winter" badge reflects when most customers stock up, not when it stops working.
Where does the "70% of immune cells live in the gut" claim come from?
The figure is widely cited in immunology research — the gut-associated lymphoid tissue (GALT) is the largest immune organ in the body. We include a daily probiotic in this bundle to support that gut-immune connection.
Do I need to take this with food?
Vitamin D3 is fat-soluble, so taking it with a meal that contains some fat improves absorption. Vitamin C and the probiotic can be taken any time, though many people take the probiotic on an empty stomach or just before bed.
Can I swap a bottle inside this bundle?
Bundle compositions are fixed — that’s how we’re able to lock in both the savings and the synergy between bottles. If you’d rather build your own mix, you can add any of our bottles individually from the shop and still get our pack-pricing discounts on each.
How does Subscribe & Save work on bundles?
Pick monthly delivery on any bundle at checkout and you save an extra 10% off the bundle price on every order. You can pause, swap, or cancel any time from your account — no fees, no questions.
Do all three bottles ship in one box?
Yes. Every bundle ships in a single box from our fulfillment partner, typically arriving in 2–5 business days. Orders over $50 get free shipping.
How long does a bundle last?
Each bundle is built around a 30-day routine — the bottles are sized so you finish them at roughly the same pace. If you subscribe, the next box arrives just as you’re running low.
What’s your return policy?
You have 30 days to try a bundle. If it isn’t working for you, email hello@moorevitamins.com and we’ll make it right — full refund, no need to ship anything back.
