7 Proven Health Benefits of Wheat Germ & How to Use It in Your Diet
A nutrient-rich ingredient that nurtures your heart, muscles, metabolism, and skin.
Wheat germ is the embryo of the wheat kernel, a small but nutrient-rich component packed with vitamins, minerals, antioxidants, and healthy fats. Although it represents only about 2.5% of the wheat grain, wheat germ is a powerhouse of nutrition, celebrated for its positive impact on heart health, blood sugar regulation, skin and muscle support, and much more. This article explores the latest scientific findings about wheat germ’s benefits, side effects, and practical ways to incorporate it into your daily diet.
What Is Wheat Germ?
Wheat germ is the part of the wheat kernel responsible for the plant’s growth and development. During processing to produce white flour, wheat germ is often removed, but retaining it in whole grains preserves their rich nutrient profile. With its mild, nutty flavor and crunchy texture, wheat germ can enhance both the nutrition and taste of a wide range of dishes.
Wheat Germ Health Benefits
- Supports Heart Health through phytosterols and omega-3s
- Regulates Blood Sugar due to fiber and alpha-linolenic acid
- May Lower Cancer Risk via antioxidants
- Boosts Muscle Performance with high-quality protein and octacosanol
- Promotes Skin Health & Anti-Aging from vitamin E and phenolic compounds
- Reduces Menopausal Symptoms owing to anti-inflammatory effects
- Supports Weight Loss with its high fiber content
1. May Improve Heart Health
Wheat germ is rich in phytosterols, plant compounds structurally similar to cholesterol. These phytosterols possess antioxidant and anti-inflammatory properties, contributing to lower LDL cholesterol levels and reduced cardiovascular risk. The body cannot synthesize phytosterols internally; dietary sources like wheat germ are essential.
Research from Harvard School of Public Health shows that daily whole grain consumption, which includes wheat germ, can help prevent coronary heart disease. Additionally, octacosanol, a unique plant chemical in wheat germ, may further reduce LDL cholesterol, while omega-3 fatty acids provide protection against heart disease-related mortality.
| Key Compounds | Benefits |
|---|---|
| Phytosterols | Reduces LDL cholesterol |
| Octacosanol | Lowers cholesterol, supports endurance |
| Omega-3 fatty acids | Reduces heart disease risk |
2. May Reduce Diabetes Risk
The high fiber content in wheat germ helps regulate blood sugar, decrease insulin resistance, and promote stable glucose levels. Studies show dietary fiber consumption may lower plasma LDL and fasting blood glucose.
Alpha-linolenic acid, an omega-3 fatty acid found in wheat germ, has demonstrated the capacity to prevent blood clots and decrease insulin resistance—both vital for reducing the risk of type 2 diabetes. Foods containing wheat germ can be particularly helpful in diets aimed at blood sugar regulation.
3. May Lower Cancer Risk
The abundance of antioxidants in wheat germ, including vitamin E and ferulic acid, helps combat oxidative stress—a contributing factor to cancer development. Animal research and emerging cell studies suggest wheat germ’s antioxidants may have anticancer activity, both for prevention and improving quality of life in cancer patients.
Avemar, a fermented wheat germ extract, has been explored as a potential adjunct to traditional cancer therapies, helping reduce side effects and improve patient outcomes. However, more large-scale human research is needed for definitive clinical recommendations.
4. Boosts Muscle Health
Wheat germ is a source of high-quality protein and amino acids, which are essential for muscle health, growth, and repair. Furthermore, octacosanol not only benefits cholesterol but can improve endurance, exercise performance, and overall muscle function.
The vitamin E and various B vitamins present also support energy production and post-workout recovery.

5. Has Anti-Aging & Skin Healing Properties
- Ferulic acid in wheat germ slows the aging process by suppressing age-related gene expression and guarding against oxidative stress.
- Vitamin E acts as a potent antioxidant, protecting skin from free radical damage and helping prevent premature aging.
- Wheat germ oil, frequently used in cosmetic products, offers photoprotective and anti-photoaging effects, reducing damage caused by sunlight.
- Its humectant properties make wheat germ oil valuable in skin moisturization, keeping skin hydrated without greasy residue.
Applying wheat germ oil or including wheat germ in your diet can help maintain youthful, healthy skin and counter dryness or irritation.
6. Reduces Menopausal and PMS Symptoms
Wheat germ’s anti-inflammatory phytochemicals may lessen the severity of menstrual cramps and menopausal symptoms.
Clinical studies indicate that wheat germ extract, taken as three 400 mg capsules per day, from the 16th day of the cycle to the fifth day of the next cycle (for two months), can notably decrease both physical and psychological symptoms of PMS as well as overall scores for discomfort.
Women who included wheat germ in this way experienced fewer mood swings, pain, and general symptoms, with no significant side effects reported.
| Menopausal/PMS Symptom | Typical Reduction after Wheat Germ Use |
|---|---|
| Physical symptoms | ~64% |
| Psychological symptoms | ~66% |
| General score | ~65% |
7. May Aid Weight Loss
Wheat germ offers high dietary fiber (about 13.2g per 100g), helping increase satiety, regulate appetite, and promote digestive regularity. Research shows that increasing fiber intake within a calorie-restricted diet may enhance weight loss results for people with obesity or overweight.
Animal studies suggest wheat germ, especially when combined with probiotics or antibiotics, may reduce food intake and body fat.
Practical applications include adding wheat germ to smoothies, salads, yogurt, or baked goods for a crunchy boost that supports fullness and weight management.
Wheat Germ Nutritional Profile
| Nutrient (per 100g) | Amount |
|---|---|
| Energy | 360 kcal |
| Protein | 26g |
| Dietary Fiber | 13g |
| Fat | 9.7g |
| Vitamin E | 20mg |
| B Vitamins | High (B1, B6, Folic Acid) |
| Minerals | Magnesium, Zinc, Selenium, Iron, Phosphorus |
This matrix of nutrients supports every major function in the body: immune health, energy metabolism, muscle repair, antioxidant defense, and more. Wheat germ is notable for offering all nine essential amino acids in trace or sufficient amounts.
How to Include Wheat Germ in Your Diet
- Mix into oatmeal, porridge, or breakfast cereal
- Add to smoothies and shakes for a nutritional boost
- Sprinkle over salads or yogurt for extra crunch
- Incorporate into baked goods—muffins, bread, pancakes
- Use as a coating for chicken or fish instead of breadcrumbs
Begin with 1–2 tablespoons daily and adjust to taste, as wheat germ has a distinct flavor and may affect texture. Store wheat germ in the refrigerator or freezer to preserve freshness and prevent rancidity.
Recommended Amounts & Safety
Most experts recommend 1–3 tablespoons of wheat germ per day, which comfortably fits within the average diet for adults. While no specific upper limit is established, excessive intake (over 50g/day) may cause digestive discomfort due to its fiber and oil content.
Potential Side Effects
- Gluten Sensitivity: Wheat germ is not safe for those with celiac disease or gluten allergies.
- Caloric Density: Overconsumption may lead to unwanted weight gain due to its calorie-rich profile.
- Digestive Upset: Sudden large increases in fiber can cause bloating or flatulence.
Consult a healthcare professional before adding wheat germ to your diet if you have underlying digestive issues or gluten intolerance.
