Your hormone panel looks off. Testosterone is lower than expected, SHBG is weird, estradiol does not match the dose, and recovery feels worse than it should.
Then the boring part of the bloodwork shows ALT at 58 and AST at 51.
ALT AST hormones liver enzymes are easy to treat as background noise. That is usually a mistake. The liver helps clear hormones, makes transport proteins, processes medication, stores glycogen, handles alcohol, and responds to inflammation. If the liver signal is off, your hormone panel needs more context.
This does not mean every elevated ALT or AST is liver disease. Hard training can move AST. Medications can move both. Fatty liver can raise ALT while also pushing SHBG down. Context is crucial.

What do ALT and AST actually measure?
ALT and AST are enzymes that leak into the blood when cells are stressed or damaged. ALT is more liver specific. AST is found in the liver, skeletal muscle, heart, red blood cells, and other tissues.
That difference matters.
A mild ALT rise often points you toward liver stress first. A mild AST rise after heavy training may be muscle related, especially if creatine kinase is also high. When both are elevated, you need to look at the pattern, not just the red flag.
Most labs use reference ranges around 40 U/L, but ranges vary. Some liver specialists treat persistently elevated ALT above the low 30s in men and high 20s in women as worth attention, especially with metabolic risk. The American College of Gastroenterology guideline on abnormal liver chemistries also warns that “normal” lab ranges can miss early liver disease in some people.
So the useful question is not “is this number barely out of range?” It is “does this result fit training, alcohol, medication, fatty liver, infection, bile flow, or a real liver problem?”
Why liver enzymes change hormone interpretation
The liver is not just a detox organ. It is one of the main places where hormones get converted, cleared, packaged, and transported.
Sex hormone binding globulin, or SHBG, is made in the liver. SHBG controls how much testosterone and estradiol travels bound in the blood versus how much is more available to tissues. Liver stress, insulin resistance, thyroid status, calories, medications, and androgens can all change SHBG.
That is why a hormone panel can look confusing when liver markers are ignored.
Low SHBG with borderline ALT can fit metabolic dysfunction or fatty liver. High SHBG with high thyroid markers can tell a different story. Estradiol can feel harder to interpret when alcohol intake, liver clearance, body fat, and medication load are changing at the same time.
A 2020 review in The Lancet Gastroenterology & Hepatology described non-alcoholic fatty liver disease as strongly tied to insulin resistance and cardiometabolic risk. That matters for hormones because insulin resistance often travels with low SHBG, lower testosterone, worse sleep, more visceral fat, and poorer recovery.
If ALT and AST are abnormal, do not read testosterone, estradiol, or SHBG in isolation. Read them with glucose, insulin, A1c, triglycerides, HDL, waist circumference, alcohol intake, medication history, and training load.
How ALT, AST, GGT, and bilirubin differ
ALT and AST get most of the attention, but they are not the whole liver panel. GGT, alkaline phosphatase, bilirubin, albumin, and platelets often explain the pattern better.
Use this as a first pass.
| Marker | What it often reflects | Why it matters for hormones |
|---|---|---|
| ALT | Liver cell stress | Often rises with fatty liver, medication stress, hepatitis, alcohol, or inflammation |
| AST | Liver or muscle stress | Can rise after hard training, muscle damage, alcohol, or liver disease |
| GGT | Bile duct and oxidative stress signal | Often tracks alcohol intake, fatty liver risk, and medication load |
| Bilirubin | Red blood cell breakdown and bile handling | High levels can be benign, but patterns matter with other liver markers |
| Alkaline phosphatase | Bile duct, bone, or liver source | Helps separate bile flow issues from pure liver cell stress |
| Albumin | Liver protein production and nutrition status | Low levels can signal more serious illness or poor protein status |
| Platelets | Blood cell count affected by liver and spleen health | Low platelets with liver abnormalities needs medical attention |
GGT is especially useful when alcohol, fatty liver, or medication load is part of the story. A normal ALT with high GGT can still be a liver stress clue. High bilirubin with normal enzymes may be Gilbert syndrome, which is common and usually benign, but you do not assume that without context.
If your goal is hormone optimisation, this panel tells you whether the hormonal signal is happening in a stable system or a stressed one.
When high AST is probably from training
AST can rise from muscle damage. Heavy lifting, endurance races, new training blocks, injections into muscle, and muscle injury can all push AST up without primary liver disease.
That is one reason lifters get false alarms.
If AST is higher than ALT after brutal training, and creatine kinase is high too, muscle is a plausible source. A study in the British Journal of Clinical Pharmacology showed that weightlifting can raise AST, ALT, lactate dehydrogenase, myoglobin, and creatine kinase for several days in healthy men. The liver was not the main issue. The muscles were leaking enzymes after damage.
The practical fix is boring. Retest after 5 to 7 days without hard training, alcohol, or unnecessary supplements. Keep hydration normal. Do not draw labs the morning after a maximal deadlift session and treat the result as a permanent diagnosis.
Still, training does not explain everything. If ALT is persistently high, GGT is high, bilirubin is abnormal, symptoms are present, or the pattern repeats after rest, do not hide behind “I lift.” Get it evaluated.
When elevated liver enzymes point to a real problem
Persistent ALT or AST elevation deserves a proper workup. The common causes include fatty liver, alcohol, viral hepatitis, medication effects, supplement toxicity, autoimmune liver disease, hemochromatosis, bile duct issues, and less common genetic conditions.
Fatty liver is the one hormone-focused people miss most often.
It is not just a liver issue. It often sits inside the same pattern as visceral fat, insulin resistance, high triglycerides, low HDL, sleep apnea, low SHBG, and lower testosterone. You can keep adjusting supplements, but the panel will keep pointing back to the same system.
Medication and supplement history matters too. Acetaminophen, some antibiotics, antifungals, anti-seizure drugs, statins, anabolic steroids, oral SARMs, high-dose niacin, green tea extract, kava, and many “liver detox” products can affect liver markers. More natural does not mean safer.
Use this decision frame.
| Pattern | More likely explanation | Next move |
|---|---|---|
| ALT higher than AST, metabolic risk present | Fatty liver or insulin resistance pattern | Check A1c, fasting insulin, lipids, waist, ultrasound if appropriate |
| AST higher than ALT after hard training | Muscle damage possible | Check CK and retest after rest |
| AST higher than ALT with high GGT and alcohol use | Alcohol related stress possible | Reduce alcohol and repeat labs with clinician guidance |
| High ALT or AST with high bilirubin | Liver or bile flow issue possible | Medical evaluation, do not self-manage |
| Persistently elevated enzymes | Ongoing liver, muscle, medication, or metabolic issue | Repeat, review exposures, and work up properly |
If values are very high, symptoms are present, urine is dark, stool is pale, skin or eyes are yellow, abdominal pain is severe, or confusion appears, that is not an optimisation problem. That is medical care now.
What should you check when hormones and liver enzymes are both off?
Do not respond to weird hormones and high liver enzymes by changing 5 things at once. Build a cleaner picture first.
A useful repeat panel usually includes:
| Category | Markers |
|---|---|
| Liver | ALT, AST, GGT, alkaline phosphatase, bilirubin, albumin |
| Muscle | Creatine kinase, LDH if training damage is suspected |
| Metabolic | Fasting glucose, fasting insulin, A1c, triglycerides, HDL, LDL |
| Hormones | Total testosterone, free testosterone, SHBG, estradiol, LH, FSH, prolactin |
| Inflammation and iron | CRP, ferritin, transferrin saturation |
| Thyroid | TSH, free T4, free T3 |
| Context | Alcohol, medications, supplements, recent illness, training, sleep |
Timing matters. Test in the morning. Keep the conditions repeatable. Avoid hard training for several days if you are trying to understand baseline AST and ALT. Do not drink alcohol before the draw. Do not start a new supplement stack the week before testing and then act surprised when the panel gets noisy.
For hormone readers, SHBG is the bridge marker. If SHBG is low, ALT is drifting up, triglycerides are high, HDL is low, and waist circumference is moving the wrong way, the likely issue is not a missing testosterone booster. It is metabolic strain.
For a broader hormone framework, read how to read your testosterone bloodwork. If fatigue is the main symptom, compare this with ferritin and iron fatigue bloodwork. If SHBG is low, read why SHBG gets low on TRT.
What actually improves liver enzymes and hormone context?
The fix depends on the cause. That sounds obvious, but this is where people get stupid with supplements.
If the pattern points to fatty liver or insulin resistance, the best evidence is still boring. Lose visceral fat. Improve sleep. Reduce alcohol. Walk more. Lift consistently without turning every session into a recovery debt. Eat enough protein. Stop living on liquid calories and late-night ultra-processed food.
A 2015 review in Journal of Hepatology found that 7 to 10% weight loss is often associated with meaningful improvement in non-alcoholic fatty liver disease features. Smaller losses can still improve liver fat. The point is not crash dieting. The point is reducing the metabolic pressure on the liver.
If alcohol is the driver, the intervention is alcohol reduction. If medication is the driver, talk to the prescriber. If training is the driver, retest after rest before making conclusions. If viral hepatitis, bile flow, autoimmune disease, or iron overload is possible, the right move is medical workup, not milk thistle.
Kabal helps because the timeline matters. Liver enzymes, SHBG, testosterone, estradiol, sleep, alcohol, training, medications, and waist change together. Looking at one screenshot from one lab draw makes people overconfident.
The Bottom Line
ALT AST hormones liver enzymes are not background noise. They can change how you interpret testosterone, estradiol, SHBG, fatigue, recovery, and medication response.
Mild AST elevation can come from hard training. Persistent ALT elevation often deserves more liver and metabolic context. GGT and bilirubin help separate alcohol, bile flow, medication, and liver stress patterns. Do not guess from one marker. Retest under cleaner conditions, read the full panel, and fix the cause instead of chasing hormones in isolation.
