Questions, answered

About Fortify.

Is this safe with my GLP-1 medication?

Yes. Every SQ[1] formula is designed to be taken alongside semaglutide, tirzepatide, and other GLP-1 medications. We deliberately exclude ingredients known to interact with these drugs (such as chromium picolinate) and stick to nutrients well-studied for safety. As with any supplement, share the panel with your prescribing physician — we publish full doses on every product page so they can review at a glance.

When will I notice the difference?

Most customers report changes in the first 2–4 weeks: more steady energy, fewer GI complaints, and easier recovery from workouts. Lab-measurable changes (vitamin D, B12, ferritin, magnesium) typically normalize over 4–8 weeks. Body-composition benefits — muscle preservation, hair, skin — show up over 8–12 weeks of consistent use.

What if it doesn't work for me?

We offer a 30-day money-back guarantee on every order. If you're not feeling the difference, email hello@getsq1.com within 30 days of delivery and we'll refund the product cost — no return shipment required. Subscription customers can also pause, skip, or cancel from their account at any time.

Do I need to take it forever?

Take SQ[1] for as long as you're on a GLP-1 — that's when the nutrient gap is largest. Many customers stay on it 3–6 months past coming off the medication while their dietary intake re-stabilizes. There's no dependency or withdrawal; you can stop any time.

Can I take this with my multivitamin?

SQ[1] Fortify is designed to layer on top of a baseline multivitamin like SQ[1] Nourish. There's minimal overlap by design — Fortify focuses on bone, joint and immune-support nutrients (calcium, vitamin K2, glucosamine) that aren't in most multis at research-based doses.

Will calcium interfere with my iron absorption?

Calcium and iron compete for absorption when taken simultaneously. We recommend taking Fortify in the evening and any iron-containing supplement (like Nourish) in the morning to maximize absorption of both.
