Three things: we dose every active at clinically meaningful amounts — the levels real research is built on, not a trace — we start with real, whole-food ingredients, and every batch is third-party tested and made in a cGMP-certified U.S. facility.^* No fairy-dusting, no fluff, every milligram printed on the label.

All Optimal Human products are manufactured in a cGMP-certified facility right here in the United States, using premium ingredients sourced from trusted growers around the world. Made in the USA isn't a sticker for us — it's where every batch actually gets made and tested.

We start with real, whole-food ingredients and source each one from growers we trust — nothing you can't pronounce, nothing added just to pad a label. Every finished batch is then third-party tested for potency and purity before it ships, so what's on the label is what's in the tub.^*

We dose every active at clinically meaningful amounts — the levels real research is actually built on, not a sprinkle for the label. That's the whole reason we started this: we got tired of paying for supplements that put a pretty ingredient list on the front and a useless dose on the back. Every milligram is printed right on our label so you can check our math.^*

Every product page has a "View Supplement Facts" section that shows the full panel — serving size, every active, and the exact amount per serving. We print all of it because the whole point of Optimal Human is that you never have to guess what's inside. If a number's missing or you want more detail, reach out and we'll walk you through it.

It depends on the product, so the honest answer is: check the label on that product's page, where we spell out the specifics for each formula. Some of our lineup (like the greens gummies) is built vegan, gluten-free, and non-GMO; others aren't a fit for every diet. If you're weighing a specific product against a specific need, ask our team and we'll point you straight.

Where our products are sweetened, we lean on things like stevia rather than added sugar — our Superfood Greens, for example, is stevia-sweetened with no added sugar. Sweeteners vary by product, so check the label on the one you're eyeing for the exact breakdown. The goal is always the same: make healthy taste good without the junk.

Allergens vary from product to product, so please check each product's label for its specific allergen information rather than trusting a blanket answer. If you have a serious allergy and want to be certain before you order, contact us and we'll get you the details on that exact formula.

For most of our powders, drink mixes, and gummies, a cool, dry spot away from direct sunlight — with the lid or pouch sealed — keeps them at their best. Every product carries its own best-by date on the packaging, so check there for specifics. Tallow and liquid products can have their own storage notes on the label, so give it a quick read when it arrives.

Yes — every single batch is tested by an independent lab for potency, heavy metals, and microbial contaminants before it ever ships. Tested, then tested again. Certificates of analysis are available on request.

Absolutely. COAs are available on request for every batch — just email our team with the product and, if you have it handy, the batch or lot number on your packaging, and we'll send the report over. We test in the open because we've got nothing to hide.

No supplement is "FDA-approved" — dietary supplements aren't approved by the FDA the way drugs are, and any brand claiming otherwise is bending the truth. What we do is manufacture in a cGMP-certified U.S. facility and third-party test every batch for potency and purity.^* *These statements have not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease.

If you're pregnant, nursing, or trying to become pregnant, please talk to your doctor before starting any supplement — including ours. Your needs during that season are specific, and your OB or midwife is the right person to give you the green light on what fits your routine.

If you take prescription medication or manage an ongoing health condition, check with your doctor or pharmacist before adding any new supplement. They can flag anything that might interact with your specific meds. It's a five-minute conversation that's always worth having.

Most of our products are built to play well together — a lot of customers run the greens plus electrolytes plus coffee as their daily stack, for example. That said, everyone's routine and health picture is different, so if you're combining several products or already take other supplements, check with your doctor first. When in doubt, start with one, get a feel for it, then layer in from there.

Our products are made from real, whole-food ingredients at sensible doses, and most people do great with them. As with any new supplement, some people notice a short adjustment period — especially with fiber, probiotics, or anything new to your routine — so ease in and drink plenty of water. If anything doesn't sit right, stop and check with your doctor.^*

Depends on the product. Our Mind Fuel nootropic shot, for instance, is built for clean focus without the caffeine jitters or crash, while our Mushroom Super Coffee is intentionally lower-caffeine for calm focus.^* Each product page and label spells out exactly what's inside, so if caffeine matters to you, check there before you buy.

Everyone's different. Many customers notice steadier energy within the first week or two, but supplements work best with consistency — give it 30 days as part of a balanced routine and let it do its thing. *These statements have not been evaluated by the FDA. Individual results may vary.

For most of our daily products, one serving a day is the move — many people take their greens or colostrum in the morning and their electrolytes whenever they need them. Each product page and label lists the exact serving and any timing tips. The single most important thing? Take it consistently — the best supplement is the one you actually remember to use.

Think of Optimal Human like eating well or moving your body — it works best as an ongoing daily habit, not a one-and-done fix.^* That's exactly why we built subscriptions: so the good habit runs on autopilot and you never scramble to reorder. You're always free to pause or cancel whenever it suits you.

Same 90+ ingredients across 8 functional blends — just different formats.^* The tub is your everyday at-home scoop and the best value per serving; the single-serve sachets are no-mess stick packs built for travel, the office, or tossing in a gym bag. A lot of customers keep the tub at home and the sachets on the go.

We do — and it's built for them, not just a shrunk-down adult dose. Our core lineup is formulated around adult nutrition needs, so for the little ones we made the Kids Superfood Greens Gummies: the same real-food nutrition in a kid-sized serving they'll actually ask for. As with any supplement, check with your pediatrician first.^*

Subscriptions ship on your schedule and save you money versus one-time orders. You can skip, reschedule, or cancel anytime from your account in a couple of clicks — no fees, no phone calls, no hassle. It's your habit, on your terms.

Your first order is charged when you place it, and each renewal is charged on the day your next shipment is scheduled — the date you'll always see (and can change) in your account. We'll send a heads-up email before a renewal processes, so there are never any surprise charges. Need to push it back a week? A couple of clicks and it's done.

All of it lives in your account — log in, open your subscription, and you can skip the next order, pause, change your ship date, swap flavors, or cancel entirely. No fees, no phone tree, no "are you sure" gauntlet. If you get stuck, our team can sort it out fast.

Yep — you're in control. From your account you can swap flavors (say, Lemon Lime to Strawberry Lemonade on the electrolytes), change quantities, or adjust what's in your recurring order. Change it as often as you like; there's no penalty for keeping it fresh.

Subscribers pay less per order than one-time buyers, and the exact savings are shown right on each product page when you choose the subscribe option. You lock in the lower price for as long as you stay subscribed — and you can still skip, pause, or cancel anytime. Best price, zero commitment.^*

Shipping is fast and flat, and it's completely free on U.S. orders over $100. Subscriptions make hitting that threshold easy since your favorites arrive on a schedule. You'll always see your exact shipping at checkout before you pay.

Orders typically process within one to two business days, then ship to your door — most U.S. customers have it in hand within a few business days of that. You'll get a tracking link by email the moment it's on its way. If anything looks stuck, message us and we'll chase it down.

Right now we currently ship within the United States only. We know folks outside the U.S. want in, and we're working on it — the best way to be first to know when that changes is to get in touch so we can flag your country.

We accept returns on unopened products. Because our supplements are consumable health products, we're unable to accept returns once a product has been opened. If your order ever arrives damaged or incorrect, reach out and our team will make it right. You can read the full details in our refund policy.

Start by contacting our team with your order number. As long as the product is unopened, we'll walk you through the return step by step. You'll find the full terms in our refund policy.

You'll find us on the shelves at GNC, Kroger, T.J.Maxx, and Harps — grab yours on your next run. Selection can vary by location, so it's worth a quick call to your local store to confirm what's in stock. Prefer your couch? Shop the full lineup online with fast, free U.S. shipping over $100.

Ask away. Our team answers real questions from real people over on our contact page — no bots, no maze. Whether it's an ingredient question, a COA request, or help with an order, we've got you.
