Wheat germ and wheat bran are two separate parts of a whole, with the third part being the endosperm. Together, they make up the kernel or seed of the wheat plant. The whole grain kernel is protected while growing in the field by the outer husk of the wheat plant.
The primary difference between wheat germ and wheat bran is the part of the wheat plant that is ground and harvested. Wheat bran is made from the outer layer of the wheat kernel, while wheat germ is found inside the plant’s endosperm. They also differ in nutrition contents and texture.
To learn more about the differences between wheat germ and wheat bran, and how they’re produced, read on.
Smoothie Tip: I add 2 Tbsp of wheat germ into every smoothie. Also, adding frozen fruit, instead of ice, enhances the flavor and nutrient content. The secret to an easy smoothie with frozen items is having a blender powerful enough to handle the workload.
The blender I recommend has a 6 blade, multi-tiered blade, check it out and the current price on Amazon, Nutri Ninja BL685 with Auto-iQ Technology. In addition, try these easy to make smoothies for incredible health, rapid weight loss and energy!

What Part of the Wheat Plant Does Wheat Bran Come From?
Wheat bran comes from the tough outer layer of the wheat plant’s kernel. When the grain is milled, the bran is separated out. It’s considered a by-product of wheat, but it’s not discarded.
After the bran is ground, it’s used as an additive to some commercially prepared foods like cereals, flours and baked goods 1.
You can purchase wheat bran separately for use at home. Some people sprinkle it in foods like cereals or smoothies for a nutritional boost with a few added fat and calories.

Nutritional Benefits of Wheat Bran
One-half cup of wheat bran will add 4.5 grams (0.15 oz) of protein along with thiamine, niacin, potassium, magnesium, phosphorus, B6, thiamin, riboflavin and iron. Small amounts of zinc, copper and selenium are also present 2.
All that for only 63 calories and less than 2 grams (0.07 oz) of fat.
Wheat bran is most famous for the dietary fiber it contains. The American Heart Association suggests 25 grams (0.88 oz) of fiber per day to help maintain heart health 3 .
One-half cup of wheat bran contains 12.5 grams (0.44 oz), or half, of the daily requirement of water-soluble fiber.
A diet high in fiber aids in digestive health by adding bulk to stools and prebiotics to maintain gut health. A high fiber diet is associated with lower rates of colon cancer 4.
Antioxidants in wheat bran support our immune systems by helping to block the formation of cancerous cells. Some see a decrease in total cholesterol after adding more fiber to their diet. In addition, fiber helps promote heart health.
The Downsides of Wheat Bran
The many health benefits found in wheat bran are sound except for those who cannot process the proteins known as glutens. Those who are gluten sensitive or diagnosed with celiac disease need to avoid wheat bran.
Others interested in adding nutritional boosters and more fiber to their diet will find wheat bran a good source. However, to avoid gastric discomfort, add fiber slowly and gradually until your body adapts to the extra fiber.
Wheat bran is also high in fructans, which are a carbohydrate. Those with IBS (irritable bowel syndrome) will want to avoid wheat bran because their digestive system does not process these carbohydrates efficiently.
What Part of the Wheat Plant Does Wheat Germ Come From?
Wheat germ comes from the plant’s endosperm. Referred to as the heart of the wheat berry, wheat germ is considered the wheat plant’s embryo and is responsible for promoting the growth of new wheat plants. During production, it’s separated and ground into flakes.
The wheat plant is topped by wavy spikes that contain wheat berries.
Take away the husk and the outer bran layers, and you’ll find the endosperm. The endosperm is the food source for wheat berries. Tucked in the endosperm is the wheat germ.
Nutritional Benefits of Wheat Germ
Wheat germ is chock-full of B vitamins, minerals, healthy fats and a small amount of protein. It’s a nutritious addition to your daily diet 5.
Wheat germ is a nutritious food supplement that can be added to just about any type of food 6. The small golden flakes tend to have a nutty taste and are frequently sprinkled into smoothies, on top of fruit or mixed with yogurt.
Two tablespoons of wheat germ sprinkled into cereal, soup or meatloaf will add only 45 calories and 1 gram (0.03 oz) of fat 7.
Why Is Wheat Germ Bad for You?
Wheat germ contains gluten, which can be bad for you and cause inflammation if you have a gluten intolerance or irritable bowel syndrome. Wheat germ also contains fats beneficial in moderation, but consuming too much can increase your overall calorie intake and affect your diet’s balance.
Wheat germ does have a lower fiber content than wheat bran, making it slightly easier to digest for some. However, if you avoid eating wheat bran because of an intolerance, then you should probably refrain from eating wheat germ too.
Wheat Bran and Wheat Germ Nutrient Content
The vitamin and mineral content of wheat bran and wheat germ are similar.
|Fat||1.5 g||0.6 g|
|Carbohydrates||7.8 g||9.7 g|

Examining the table above, which is healthier wheat bran or wheat germ? Wheat bran is healthier than wheat germ because it has less calories and contains more fiber, calcium, iron, potassium, magnesium, phosphorus and niacin per serving than what germ.
Although wheat germ provides a good number of these nutrients as well. Wheat germ contains more zinc, folate and protein. If you want to boost your fiber significantly, then wheat bran is an efficient and effective way to do that. However, wheat germ is more easily digestible.

Are Wheat Bran and Wheat Germ Considered Whole Grains?
Wheat bran and wheat germ are not individually considered whole grains because they are separated from the wheat berry during production. Instead, whole grain wheat products utilize the entire wheat berry or kernel, which includes bran, germ and endosperm.
The three parts of the wheat berry are kept whole to make whole grain products, like cereal and flour 8.
How Is the Wheat Plant’s Endosperm Used?
The wheat plant’s endosperm is typically used to make white flour. The endosperm surrounds the wheat germ and is ground into a fine powder during production. The endosperm is also rich in vitamins and minerals.
However, when the endosperm, bran and germ are all kept intact and ground together, they produce whole grain flour instead of white flour.

Wheat Germ vs Wheat Bran: Which Cost More?
Wheat bran costs more than wheat germ. Wheat bran cost 0.20 cents per serving and wheat germ cost 0.18 cents per serving. Consuming one serving per day for a whole month, wheat bran will cost 0.60 cents more per month.
Surprisingly, the cost is not much of a difference. This is great news for whichever product you choose. I priced each one at a local Walmart and divided the total cost by serving to find the answer.
Both products are difficult to find in the local supermarket. I have better luck finding wheat germ in the cereal isle but it’s often hidden on a shelf somewhere. Amazon sells both of them at comparable prices. Check out the current price here, Wheat Germ and Wheat Bran.
Can I use wheat germ instead of wheat bran? Wheat germ can be used instead of wheat bran. The two are similar to each other and can be used interchangeably without making a noticeable difference in the food dish prepared. The two can be substituted in a 1:1 ratio.
Wheat bran or wheat germ for constipation? Wheat bran is better for constipation because it contains more fiber than wheat germ. Wheat bran contains a good number of insoluble fiber, 6.4 grams per serving, which helps speed the flow of waste through the intestines.
Wrapping Up The Wheat Germ and Wheat Bran Difference
The main difference between wheat germ and wheat bran is the part of the wheat plant 9 used. Both wheat bran and wheat germ offer tremendous health benefits and can boost your fiber intake.
They are suitable toppings for fruit, yogurt and smoothies. However, those suffering from digestive problems or irritable bowel syndrome, should probably avoid consuming wheat germ and wheat bran.
