Frequently asked questions.

Three things: clinical dosing, bioavailable forms, and 40 years of practice-tested formulation. Most store supplements are underdosed or in a form the body absorbs poorly. Magnesium Oxide has roughly 4% absorption; Magnesium Glycinate — what we use — is dramatically better. More on the Schrock Difference.

Dietary supplements are not "approved" by the FDA the way pharmaceutical drugs are — this applies to every supplement brand. The FDA regulates supplements under a different framework: GMP-certified manufacturing facilities, ingredient purity testing, no disease claims, and adverse-event reporting requirements. All products on this site comply fully. The FDA disclaimer on every product is required by law for all US dietary supplements.

Most products do not contain gluten, dairy, soy, or common allergens, but formulations vary by product. Always check the ingredient list on the specific product page. If you have questions about a specific ingredient, email hello@drschrock.com and we'll answer directly.

Most botanical and nutritional supplements require consistent daily use for 30–60 days before meaningful results are noticeable. Supplements work with your body's natural processes — that takes time. Some products (Magnesium for sleep, Lavender Oil for relaxation) produce more immediate effects. Others — Joint Help, Prostate Support, Adrenal Support — build systemically over 60–90 days. Consistency is the single biggest factor.

Many of our customers take several products together, and most of the formulas are designed to complement each other. If you're on prescription medications, consult your physician before adding new supplements — some combinations interact with certain prescription medications. We've spent years putting together coordinated multi-product approaches in our Protocols.

Consult your OB-GYN or midwife before taking any supplement during pregnancy or while breastfeeding. Many botanical compounds have not been studied in pregnant populations, and some that are safe generally are contraindicated during pregnancy. Please check with your provider first — this is genuinely important advice, not a generic disclaimer.

Some supplements interact with medications — particularly blood thinners, thyroid medications, diabetes medications, and antidepressants. Check the ingredient list of any product you're considering with your prescribing physician or pharmacist before adding to your regimen. It's worth the 5-minute conversation.
