"Started in my calf. Spread to my foot. This stopped both."
My doctor said keep taking magnesium. I gave this six weeks instead. The foot cramps stopped first. Then the calf. Wish I found it sooner.
"Back to my morning walk for the first time in a year."
The cramps ruined my sleep so badly I stopped exercising. Month two on this and I am back to three miles every morning.
"I kept a list of everything I tried. This is the last thing on it."
Four forms of magnesium. Tonic water. Pickle juice. Two years. A retired nurse told me it was a blood flow problem. She was right.
Your blood gets thicker as you age. At night, less blood reaches your calf. The muscle runs low on oxygen, waste builds up, and the nerve fires. That is the cramp. FlowRest thins the blood, opens the vessels, and helps the muscle use the oxygen once it arrives.
2 capsules on an empty stomach, one hour before bed. That is it. Empty stomach so the enzymes work on your blood, not your food.
Magnesium calms the nerve after the cramp starts. It never touches the blood flow problem that caused it. A JAMA study tested magnesium against a sugar pill in adults over 65. No difference. FlowRest starts at the cause, not the symptom.
Most people notice a shift around week three or four. Blood takes time to thin. Vessels take time to open. Give it six weeks. Stopping at ten days is stopping too soon.
If you take warfarin, Eliquis, or Xarelto, talk to your doctor first. Nattokinase affects how blood behaves and so do those drugs. For most people on statins only, there is no issue.
Try FlowRest for 30 days. If your nights haven't changed, we refund you in full. No forms. No questions. See our Refund Policy.

6 Ingredients. All Aimed At Your Blood.
Every Ingredient
Has a Job.
Cramps start when blood stops reaching your calf overnight. Each ingredient below fixes part of that.
Nattokinase 10,000 FU
Thins The BloodYour blood gets thicker as you age. Nattokinase breaks that down so blood can reach your calves again.
Pine Bark Extract
Opens The VesselsHelps vessel walls relax and let more blood through. A study of 113 people showed up to 40% fewer cramps.
CoQ10
Restores Muscle EnergyStatins deplete CoQ10 without telling you. This puts it back so your muscles can use the blood once it arrives.
Bromelain
Second Blood AngleWorks with nattokinase to thin the blood. Two enzymes, same problem, different angles.
Aged Garlic Extract
Softens ArteriesStiff arteries push blood less well. Aged garlic helps them stay soft and flexible.
Turmeric

No fillers. No blends. Every dose is on the label.
Quality You Can Trust.
Nattokinase comes from natto, a fermented Japanese food used for over a thousand years.
Ours is made in a cGMP facility, non-GMO, and third party lab tested. What is on the label is what is in the capsule.

FLOWREST FAQ
Your Biggest Questions, Answered
Real answers before you try it.
Will this actually stop my cramps?
Most cramps happen because blood stops reaching the calf overnight. Nattokinase thins the blood. Pine bark opens the vessels. CoQ10 helps the muscle use the oxygen. When blood reaches the muscle, the nerve has nothing to react to. The cramp never fires.
I've tried magnesium. Why didn't it work?
Magnesium works at the nerve after the cramp has already started. It never touches the blood flow problem that caused it. A JAMA study tested magnesium against a sugar pill in adults over 65. No meaningful difference. FlowRest starts at the cause, not the symptom.
How do I take it?
2 capsules on an empty stomach, one hour before bed. Empty stomach so the enzymes work on your blood, not your food. Before bed so they are active during the hours when cramps happen most.
When will I feel something?
Most people notice a shift around week three or four. Blood takes time to thin. Vessels take time to open. Give it six weeks. Stopping at ten days is stopping too soon.
I'm on a statin. Does that matter?
Yes and it matters a lot. Statins deplete CoQ10 without telling you. CoQ10 is what your muscle cells need to use oxygen. Even if more blood reaches your calf, a CoQ10-depleted muscle still can't use it properly. That is exactly why CoQ10 is in this formula.
I'm on a blood thinner. Can I take this?
If you take warfarin, Eliquis, or Xarelto, talk to your doctor first. Nattokinase affects how blood behaves and so do those medications. For most people on statins only, there is no issue. That conversation is not one to skip.
Why not just take nattokinase by itself?
Nattokinase thins the blood but does not open the vessels or restore muscle energy. Pine bark works on the vessel walls. CoQ10 fixes what statins deplete. Without all three you are still leaving parts of the problem untouched.
What if it doesn't work for me?
Cramp free or your money back. Try it for 30 days. If your nights haven't changed, we refund you in full. No forms. No questions. See our Refund Policy.
