What Is Okra?
Okra (Abelmoschus esculentus, Abelmoschus manihot) is a tropical plant from the mallow (Malvaceae) family. This is the same family of plants as marshmallow, cotton, and hibiscus. It is also known as lady’s finger, bhindi, and gumbo [1, 2].
Traditional uses include treatment of stomach ulcers, indigestion, diarrhea, and constipation. Okra is also used as a remedy for infections, fever, and arthritis. Others use it as a treatment for skin wounds, pimples, and itchiness .
Okra Nutrition Facts
- 31% carbohydrate
- 14% protein
- 8% fiber (soluble)
- 2% fat (linolenic, linoleic acid, oleic acid)
Okra is also rich in vitamins, including :
- Flavonol derivatives
- Hydroxycinnamic derivatives
- Quercetin and derivatives
- Pectic rhamnogalacturonan I structure
How It Works
Okra may achieve its health benefits through numerous mechanisms of action, including:
- Increasing the breakdown of glucose and fat (by reducing levels of a receptor called PPARγ) .
- Reducing fasting insulin and blood glucose (by increasing glycogen and glucose entry into muscle tissue) [12, 13].
- Causing programmed cell death of tumor cells (through the increase of genes called caspase-3, caspase-9, and p21) .
- Increasing tumor cell destruction by reducing inflammatory signals (such as inducible nitric oxide protein, tumor necrosis factor, and NF-κB) [15, 14].
- Protecting the liver (by causing an increase in superoxide dismutase, catalase, glutathione peroxidase, and glutathione) .
- Reducing signs of liver damage (by reducing levels of enzymes called SGPT and total bilirubin) [16, 17].
- Increasing albumin, a beneficial blood protein made in the liver [18, 16].
- Reducing the absorption of cholesterol from the gut .
- Increasing blood antioxidants (such as malondialdehyde, superoxide dismutase, glutathione peroxidase, and catalase) [13, 20].
- Blocking H. pylori from sticking to healthy stomach cells [21, 22].
- Reducing sun damage (through a pathway called Nrf2-ARE) .
- Decreasing harmful substances in nerves (reactive oxygen species and hydrogen peroxide) .
- Reducing the activation of a protein linked to Alzheimer’s disease (called tau phosphorylation) .
- Reducing kidney damage. Okra decreases proteinuria and oxidative markers (beta 2-microglobulin, N-acetyl-beta-glucosaminidase, lipid peroxide, superoxide anion) in the kidneys [25, 26].
Health Benefits of Okra
Possibly Effective for:
In a study of 417 patients with kidney disease, ornamental okra reduced high protein levels in the urine, which is a marker of kidney damage .
In 35 patients with kidney disease related to diabetes, ornamental okra acted as an antioxidant, reduced high protein levels in the urine, and increased kidney function. A systematic review of 7 trials and over 500 people concluded that okra may be used as an add-on therapy in people with kidney damage from diabetes [26, 27].
All in all, promising but limited evidence suggests that okra may help with kidney disease. You may discuss with your doctor if including okra in your diet or taking supplements could be helpful in your case.
Animal and Cell Research (Lack of Evidence):
No clinical evidence supports the benefits of okra for any of the conditions listed in this section. Below is a summary of the existing animal and cell-based research, which should guide further investigational efforts. However, the studies listed should not be interpreted as supportive of any health benefit.
Okra also enhanced sugar use by the muscles in diabetic rats (increased muscle glycogen) .
Okra supplements reduced sugar absorption in the gut of diabetic rats .
In a cell-based study, okra extract prevented the death of the pancreatic cells that produce insulin (beta-cells) .
In diabetic rats, it reduced harmful cholesterol in the blood (total cholesterol, LDL cholesterol, and very-low-density lipoprotein compared to controls) and increased beneficial HDL cholesterol [16, 13].
- Improving liver appearance and activity (improved morphology and increased superoxide dismutase, catalase, glutathione peroxidase, and glutathione)
- Normalizing liver enzyme levels (SGPT and total bilirubin)
- Increasing a beneficial blood protein made in the liver (albumin) by up to 30%
- Increasing total blood protein levels
- Increasing enzymes that break down harmful compounds and protect cells from damage (Superoxide dismutase (SOD), Catalase (CAT), Glutathione peroxidase (GPx), Glutathione (GSH))
- Reducing lipid peroxidation, which can lead to heart disease
- Reducing markers of cell damage (Malondialdehyde -MDA-)
The okra seed, but not the pod, improved markers of endurance in mice (swimming time) .
Okra seeds reduced harmful compounds that decrease energy production (reduced blood lactic acid and blood urea nitrogen), while increasing energy storage, liver and blood vessel protection (increased glycogen and malondialdehyde, superoxide dismutase, and glutathione peroxidase) [20, 47, 48, 49].
A similar study in rats found that it reduced nerve-related inflammation and pain (temporomandibular joint) .
In mice, both okra extract and its flavonoids quercetin and rutin prevented the brain damage caused by a drug (dexamethasone) and the resulting cognitive impairment .
Some genes increase the risk of Alzheimer’s disease (hemochromatosis gene). In a cell-based study, okra increased beneficial antioxidants in cells with this gene (decreased reactive oxygen species (ROS) and tau phosphorylation), which may protect against disease .
Limitations and Caveats
Research on okra in humans has been limited to ornamental okra, and may not extend to other varieties. Most potential benefits have only been tested in animals and cells. The effects of dietary okra may not be the same in humans.
Side Effects & Precautions
However, it reduced sexual function in animal studies and resulted in increased body weight.
- Reduced testicle weight and function
- Reduced sperm count and movement
Men trying to have children should consult taking okra with their doctors.
Supplement/Herb/Nutrient-drug interactions can be dangerous and, in rare cases, even life-threatening. Always consult your doctor before supplementing and let them know about all the drugs and supplements you are using or considering.
You may eat okra or take supplements if you and your doctor determine that it could be appropriate for your health condition. Remember that taking okra should never be done in place of what your doctor recommends or prescribes.
Because okra is not approved by the FDA for any conditions, there is no official dose. Users and supplement manufacturers have established unofficial doses based on trial and error.
Supplemental doses of 400 mg okra capsules are available. It is also sold as okra pepsin E3.
For kidney disease, doses of 2.5 g, 3x/day of ornamental okra were standard .
Okra is eaten in typical food amounts.

Users taking supplemental okra claim that it helped coat their stomach and improve digestion. Some people also gave it to their pets for digestive health.
Some users disliked the slimy texture of okra; cooking it quickly or incorporating it into soups reduces the undesirable texture according to some.
