Question 1

Does this actually work?

Accepted Answer

Every formula uses clinical doses of ingredients with human trials behind them. We link studies on each ingredient page so you can check the evidence yourself. Results vary by person, but the dosing matches what the research used.

Question 2

Is it safe?

Accepted Answer

Made in FDA-registered, GMP-certified facilities in the US. Every batch is third-party tested for potency, heavy metals, and microbial contamination. If you're on prescription meds or pregnant, check with your doctor before any supplement, ours included.

Question 3

When will I feel it?

Accepted Answer

It depends. Stimulant-style ingredients (caffeine, citrulline, theanine) show up in 30 to 60 minutes. Most nutrient and adaptogen benefits build over 2 to 4 weeks. If you're not feeling anything by week six, something's off. Tell us.

Question 4

What if I don't like it?

Accepted Answer

90-day refund guarantee, no questions. Email hello@ingredientmd.com, we refund the order. You keep any bonuses. Shipping's free both ways within the US.

Question 5

How do I cancel my subscription?

Accepted Answer

One click in your account at ingredientmd.com/shop/orders. No phone call, no retention department, no dark patterns. You can pause, skip a month, or cancel outright.

Question 6

Do you ship internationally?

Accepted Answer

Not yet. US addresses only for now. International fulfillment is on the roadmap and we'll post an update when it ships.

Question 7

What's a COA?

Accepted Answer

Certificate of Analysis. A third-party lab report showing the batch's potency, purity, and heavy-metal test results. We post one per batch, linked from each SKU page. If a brand can't show you one, that's a flag.
