Moringa benefits, like preventing diabetes and promoting heart health, stem from its rich nutrient profile containing iron, calcium, carotenoids, quercetin and vitamin C, as well as active substances such as polyphenols and chlorogenic acid. These compounds give this plant its antioxidant, antidiabetic, analgesic and anti-inflammatory properties, with over 100 bioactive compounds characterized in recent comprehensive research.
Moringa (Moringa oleifera) is a medicinal plant that can be taken to help manage blood sugar levels, assist in the treatment of respiratory problems, protect the liver, reduce muscle fatigue and promote weight loss. Recent systematic reviews analyzing 573 primary research articles have demonstrated promising efficacy for diabetes mellitus, obesity, cancer, hypertension, and dyslipidemia.
However, while extensive research supports many moringa benefits, consultation with healthcare providers remains important before starting supplementation. The FDA has not approved moringa as a registered food supplement, and should therefore only be taken as directed by your doctor or a medicinal plant specialist.
Health benefits
According to recent scientific studies and systematic reviews, moringa may be beneficial for:
1. Increasing breast milk supply
Moringa is often prescribed as a galactagogue to help increase breastmilk production. Although its exact mechanisms are not fully known, it appears to have phytoestrogens that work similarly to estrogen in the body. It also appears to improve prolactin hormone levels, supporting milk production.
2. Increasing respiratory capacity
Moringa helps relieve symptoms associated with chronic respiratory diseases like asthma by increasing hemoglobin levels and oxygen circulation.
3. Preventing diabetes
Moringa has antioxidant properties that reduce oxidative stress, lower blood sugar, and protect tissue from damage. Clinical trials showed glycemic control with 8g/day of leaf capsules and 2400mg/day of powder. Animal studies showed effective doses of 100–300 mg/kg over 2–8 weeks.
4. Protecting the heart
Because it is rich in fiber, this plant helps reduce cholesterol absorption and formation of arterial plaques. Its antioxidant effects reduce systemic inflammation, contributing to overall cardiovascular health.
5. Managing blood pressure
Tocopherols, polyphenols and flavonoids in moringa act as natural vasodilators, improving circulation. A systematic review of 16 clinical studies found blood pressure-lowering effects in hypertensive individuals with no significant impact on liver or kidney function.
6. Helping with weight loss
Rich in fiber and protein, moringa promotes satiety and may reduce intake of high-calorie foods. Some animal studies also show enhanced fat burning.
7. Preventing and treating anemia
Moringa leaves are high in iron (105 mg per 100g), promoting red blood cell production and helping treat iron-deficiency anemia.
8. Increasing immunity
Moringa contains vitamin C, polyphenols, and beta-carotene. Studies in HIV patients show moringa supplementation increases CD4 cell counts and modulates immune function, helping balance overactive and underactive immune responses.
9. Analgesic and anti-inflammatory effects
It contains isothiocyanates, quercetin and chlorogenic acid, which reduce inflammation. It inhibits the TLR-4/NF-κB pathway and shows effectiveness in managing inflammatory conditions.
10. Protecting and hydrating the skin
Its B-complex vitamins and vitamins C, E, and A stimulate collagen formation and aid wound healing and hydration.
11. Improving digestion
Moringa’s fiber helps manage constipation, while antioxidant properties support treatment for gastric ulcers and hemorrhoids by improving circulation.
12. Preventing cancer
Some research suggests anticancer potential, particularly in breast and intestinal cancer, through stimulation of malignant cell destruction.
13. Improving vision
Moringa is rich in beta-carotene (precursor to vitamin A) and antioxidants like lutein and zeaxanthin (26,100 mcg/100g), which support eye function and protect against degeneration.
14. Decreasing menopause symptoms
Due to its antioxidant and hormone-regulating effects, moringa may reduce symptoms related to hormonal changes during menopause.
15. Preserving bone health
Its high calcium content supports bone strength and may help prevent conditions like osteopenia and osteoporosis.
16. Protecting the liver
With antioxidant and anti-inflammatory properties, moringa helps reduce liver fat accumulation and supports liver function. Research shows enhanced antioxidant enzyme activity and reduced inflammatory markers.
17. Reducing muscle fatigue
Moringa improves physical performance by mobilizing fat stores and slowing glycogen depletion. It may reduce lactate buildup from exercise.
18. Treating yeast infections and other fungi
Its alkaloid and flavonoid content may inhibit fungal growth, including Candida albicans, Aspergillus, Fusarium, Penicillium and others.
Moringa properties
Moringa contains antioxidant, anti-inflammatory, analgesic, anti-diabetic, vasodilator, anticholinergic, anti-rheumatic, antihypertensive, antimicrobial, hepatoprotective and healing properties.
However, some clinical applications are still under investigation and not fully confirmed.
Different forms of moringa
Moringa tea
Use 1 tsp of dried moringa leaves per cup of water. Steep for 5 minutes in warm (not boiling) water. You may also use 1 tsp of moringa powder per cup. Always follow manufacturer instructions.
Moringa capsules and powder
Capsules are typically taken once daily before breakfast. Moringa powder can be added to water, smoothies, yogurt or soups. Dosage varies by brand, so check product labels.
Dosage recommendations
- Capsules: 8g/day shown effective for glycemic control
- Powder: 2400mg/day for 12 weeks improved blood sugar markers
- Animal studies: 100–300 mg/kg over 2–8 weeks
- Human studies: Up to 20g of powder per day for at least 2 weeks
Toxicity studies in mice showed an LD50 of 3,900 mg/kg, with no mortality at doses of 500–2000 mg/kg. Wistar rat studies showed no liver or kidney toxicity at 800 mg/kg.
Comparison with other superfoods
Moringa contains vitamins A, B, C, D, E, and K. WHO recognizes it as one of the richest antioxidant sources among edible plants. Compared to leafy greens, it has higher levels of:
-
Vitamin C: 51.70mg (57% DV)
-
Vitamin B6: 1.20mg (71% DV)
-
Vitamin A: 378mcg (42% DV)
Detailed nutritional profile
Side effects and safety information
Possible side effects include nausea, vomiting, diarrhea, and rare allergic reactions (e.g., facial swelling, difficulty breathing). In very rare cases, moringa has been associated with rhabdomyolysis, a serious condition involving muscle breakdown.
Some case reports link high doses to skin reactions. Avoid bark, roots and root extracts, as they may contain toxic compounds linked to paralysis and death.
Contraindications for use
Moringa should not be taken by:
- Pregnant women (safety not confirmed)
- People with thyroid disorders (may interfere with hormone production)
Always consult your doctor before use, especially if you have chronic conditions or take medications.
