The average person serious about their circulation is taking six, seven, eight different supplements.

An energy formula. Something for the heart. Magnesium before bed. CoQ10 somewhere in the mix. Each one purchased for a good reason.

None of them were designed to work together — and none of them were designed around the fact that circulation has two distinct biological phases.

Daytime and overnight. Activation and repair. Two completely different physiological demands — running on a 24-hour cycle your body never switches off.

FLOW AM + PM was built around that reality. Not another supplement for the shelf — a complete system to replace most of what's already on it.

The Reasons Why the FLOW Stack Will Replace Your Circulation Supplements — For Good

"I was spending over $200 a month on separate supplements — CoQ10, magnesium, a circulation formula, something for energy, something for sleep. My kitchen drawer was a mess and I still wasn't feeling the difference I was looking for. A friend recommended FLOW and honestly I was skeptical. Now it's the only thing I subscribe to. It shows up at my door every month, I take two capsules in the morning and two at night, and I've cancelled everything else. Wish I'd found this two years ago."

"My sock marks are finally gone!"

I've had those deep red sock marks around my ankles for years. My legs would just swell up during the day and by the time I took my socks off in the evening it looked awful. My doctor said it was just poor circulation. I tried compression socks, elevating my legs, all of it. About five weeks after starting FLOW I realised the marks had basically disappeared. My ankles look normal again. I didn't expect that at all, it wasn't even the main reason I bought it.

"From non-restorative to highly restorative sleep"

I've had a Garmin for three years so I've got a lot of data. My sleep score was sitting in the low 40s pretty consistently, non-restorative, poor quality, the watch would basically tell me I needed a nap every morning. I started taking FLOW PM about a week before this screenshot and honestly didn't connect the two at first. Then I looked at the trend and it was obvious something had changed. 94, highly restorative. I'm sleeping the same hours. Whatever is happening overnight is different.

"My hands are finally warm"

I've had cold hands my whole adult life. Like embarrassingly cold — I'd warn people before shaking hands. In winter they'd go completely white and take ages to come back. I bought FLOW mainly for energy but around week three I was making coffee and just noticed my hands looked... normal? Pink? I held them next to my husband's and they were basically the same temperature. I actually cried a little bit. Twenty years of cold hands and this is what helped.

"The dark circles I'd accepted as permanent"

I thought my dark circles were just genetics. My mum has them, I have them, I'd made peace with it. I wasn't taking FLOW for that reason at all. I started it because of the afternoon energy crashes. About six weeks in a colleague asked if I'd been on holiday because I looked 'fresher.' I hadn't changed anything else. No new skincare, same sleep hours. I think the overnight repair aspect of the PM formula is doing something because the difference in the mirror is real. I still can't fully explain it but I'll take it.

"The redness I couldn't get rid of"

I've had this patchy redness across my cheeks and nose for years. Tried every skincare thing you can think of. Was told it was rosacea, then told it wasn't, then told to just manage it with products. Someone in a health forum mentioned that vascular instability can show up in the skin and suggested I look into circulation support. I was sceptical but tried FLOW. Two months later the patchiness had calmed down dramatically. I'm not saying it's a skin product. But whatever it's doing to my circulation is showing up on my face.

"I replaced 11 supplements with two"

That shelf was my life for about four years. I was taking eleven separate things just for circulation. CoQ10, nattokinase, magnesium, citrulline, beetroot capsules, you name it. I'd built my own stack from reading studies. It was exhausting to manage and honestly expensive. When I looked at what FLOW AM and PM actually contained I realised it covered almost everything I was taking, in better forms, at better doses, timed properly for day and night. The shelf is clear now. I feel better organised and I feel better generally. I wish I'd found this two years ago.

Why Cold Hands and Feet Are a Circulation Signal (Not Just Bad Luck)

Millions of people write off cold extremities as genetics or thin blood. The biology tells a different story — one that connects your peripheral warmth directly to nitric oxide, vascular tone, and how well your body manages circulation under stress.

Brain Fog Isn't in Your Head — It's in Your Blood Flow

What Happens to Your Cardiovascular System While You Sleep

Eight hours of darkness aren't passive. Your blood vessels repair, your endothelium restores itself, your blood pressure resets, and the systems that protect your arteries do their most important work — all while you're unconscious. Here's what that actually looks like.

General information

Product information

Usage & Safety

Shipping & Delivery

What is the FLOW AM + PM system?

FLOW is a two-part daily supplement system designed to support healthy circulation around the clock. The AM formula supports daytime blood flow and delivery, while the PM formula supports nighttime vascular maintenance and recovery.

Who is FLOW designed for?

FLOW is designed for adults looking to proactively support circulation and long-term cardiovascular wellness as part of a daily routine.

Is FLOW intended to replace medication?

No. FLOW is a dietary supplement and is not intended to diagnose, treat, cure, or prevent any disease. Always consult your healthcare professional before making changes to medication or supplement routines.

How long does it take to notice benefits?

Individual experiences vary. Some users notice changes in energy or circulation awareness within weeks, while others experience benefits with consistent, long-term use.

How is FLOW packaged?

FLOW is delivered in sealed, zip-lock refill pouches. One-time purchases include refill pouches only. Customers on the subscription plan receive optional refillable glass jars with their first order, and subsequent monthly refills are delivered in zip-lock pouches designed for freshness and convenience.

Do you offer a money-back guarantee?

Yes. We offer a 30-day money-back guarantee on your first purchase. If you’re not satisfied for any reason, contact our support team within 30 days of delivery and we’ll help make it right.

What’s the difference between FLOW AM and FLOW PM?

FLOW AM supports circulation, oxygen delivery, and vascular responsiveness during the day. FLOW PM supports overnight circulation maintenance, vascular relaxation, and recovery.

Are the ingredients clinically studied?

Yes. FLOW is formulated using ingredients and standardized extracts that have been widely researched in scientific literature for their role in supporting circulation and vascular function.

Does FLOW contain stimulants or caffeine?

No. Both formulas are non-stimulant and caffeine-free.

How long before I notice results?

Initial effects (better circulation, warmer extremities) often occur within 4-8 hours. Energy improvements typically manifest within 7-10 days. Measurable blood work changes (D-dimer, fibrinogen, blood viscosity) show up at 4-6 weeks. Maximum benefits are usually achieved by week 8-12. The key is daily consistency - sporadic use eliminates the cumulative fibrinolytic effect.

How do I take FLOW?

Take 2 capsules of FLOW AM in the morning, preferably with food. Take 2 capsules of FLOW PM in the evening, preferably with or after your last meal.

Does FLOW contain any common allergens?

FLOW AM and FLOW PM do not contain gluten, dairy (including milk, whey, or casein), eggs, peanuts, tree nuts, fish, shellfish, or sesame.

FLOW PM contains nattokinase, an enzyme derived from fermented soybeans (natto). We warn customers that this product contains traces of soy.

Who should not take FLOW?

FLOW is not recommended for individuals who are pregnant or breastfeeding, or those taking blood pressure medications, blood thinners, nitrates, or with underlying medical conditions without consulting a healthcare professional.

Can FLOW be taken long-term?

FLOW is designed for consistent daily use as part of a long-term wellness routine. Do not exceed the recommended dose.

Should I stop using FLOW before surgery?

Yes. Discontinue use at least 14 days prior to any scheduled surgery or dental procedure.

Where do you ship?

We currently only ship within the United States.

How long does shipping take?

Orders are typically processed within 1–2 business days. Standard delivery usually arrives within 3–7 business days after shipment.

Do you offer subscriptions?

Yes. FLOW is available as a monthly subscription so you never run out. You can pause or cancel anytime.
