I checked the labels behind that shin test. Three of five didn't have the number.

The dent means it's fluid, not fat. But the test doesn't tell you what to do about it. That's the part I reviewed.

This week I got the same question twice: if the dent stays, then what? I review supplement labels for a living, so I sat down to look at what comes after the test.

What the dent means

Fat bounces back when you press it. Fluid between the cells doesn't bounce. It sinks and takes time to return. That's what you're seeing when the dent holds: it's not fat. It's fluid that builds up when the body's drainage is running behind.

Why it collects in the belly

Your liver is the body's drainage system. It decides how fast the excess clears out. When it falls behind, that fluid settles wherever there's the most room: the belly. That's why it feels tight, like a drum, and why it's bigger at night than in the morning. Fat doesn't behave that way. Water does.

Why diet and exercise don't touch it

Walking burns calories; the fluid between your cells isn't calories. Eating less targets fat; the fluid doesn't notice. That's why some men lose weight and the belly stays just as tight. They weren't doing it wrong. They were aiming at the wrong problem. And at a routine checkup, almost nobody explains this, because it's not a disease. It's just a drain that's running slow.

The number almost nobody checks: 30 versus 80

There's a seed that helps the liver drain better: milk thistle. The compound that does the work is called silymarin. I checked five bottles from different pharmacies: three didn't list a silymarin percentage anywhere. They just said "seed extract." The other two were between 30 and 50 percent.

The studies that show results use extract standardized to 80 percent. In a 300-milligram dose, the difference is between roughly 90 milligrams of active compound and 240. If you've ever tried milk thistle and felt nothing, you probably never took the full dose. That's not the plant's fault. Almost nobody tells you what's actually in the bottle.

The brand that prints the number: Enerra

Of the five formulas I reviewed, Enerra is the only one with the number printed on the label. 300 milligrams of milk thistle at 80 percent. That's 240 milligrams of the active compound. It also contains inositol, pueraria, turmeric, vitamin C, and L-methionine. Nothing hidden behind the word "extract." And it doesn't ask you to quit drinking. It just gives your liver what it needs to keep up.

The numbers I check before recommending anything

More than 53,000 people take it. Fewer than 1 percent have ever asked for their money back. It carries 4.7 stars, verifiable on the product page. The guarantee runs 90 days, not 30 or 60. The liver doesn't catch up in a month. The buy 2, get 1 free bundle covers exactly those 90 days. If the belt notch hasn't moved by day 90, send the bottles back, even empty, and get a full refund.

Before you pay

Flip any milk thistle bottle over and look for the silymarin percentage. If it's not there, you know what you bought: the name of the plant, not the plant. The dent test told you what the problem was. Now you know what number to look for.

Quick questions

Do I have to quit drinking?
No. The idea is giving your liver what it needs to work, not taking anything away.

When will I notice something?
First few days, more bathroom trips. That's a good sign. Face puffiness, one to two weeks. Belt notch, between week three and week eight.

What's in the formula?
Milk thistle 300mg at 80% silymarin (240mg active), plus inositol, pueraria, turmeric, vitamin C, and L-methionine. The percentage is printed on the label, not hidden.
