Goji Seeds Overview
What Are Goji Seeds?
You may know goji seeds as the tiny seeds found inside goji berries. These berries come from the Lycium plant, which grows as a thorny shrub. The most common species are Lycium barbarum and Lycium chinense. People have used these plants for centuries, especially in China, Korea, and Japan. In traditional medicine, goji seeds and berries serve as a tonic for your liver, kidneys, eyes, and lungs. Ancient texts describe them as a food that helps you stay healthy and live longer.
Goji plants grow up to three meters tall. Their leaves are narrow and fleshy. The flowers are small and purple. The fruit, which holds the seeds, ranges in color from reddish-orange to black. Black goji berries are known for even more health-promoting properties. Farmers harvest the berries, then dry or process them for food and medicine. You can find goji seeds in soups, teas, juices, and even wines.

Goji seeds are part of the fruit’s pericarp, which means they are surrounded by the berry’s pulp and skin. This structure helps protect the seeds and keeps their nutrients safe until you eat them.

Goji Seeds Benefits
Antioxidants
Goji seeds give your body a strong boost of antioxidants. These natural compounds help protect your cells from damage caused by free radicals. When you eat goji seeds, you get polysaccharides, carotenoids like zeaxanthin, and phenolic compounds such as caffeic acid and rutin. These nutrients work together to fight oxidative stress.
- Clinical studies show that drinking goji juice can improve antioxidant markers in your blood.
- Eating goji berries increases your body’s antioxidant capacity and raises levels of reduced glutathione, which helps keep your cells healthy.
- Research links these antioxidant effects to better heart health and protection against diseases caused by cell damage.
Antioxidants from goji seeds may help lower your risk of chronic diseases and support your overall well-being.
Immune Support
You can support your immune system by adding goji seeds to your diet. The polysaccharides and carotenoids in goji seeds help your body fight off illness. These compounds help your immune cells work better and may reduce inflammation.
A clinical trial with older adults found that goji berry supplements improved the immune response to a flu vaccine. This means your body can defend itself more effectively. Animal studies also show that goji seeds help increase good gut bacteria, which play a role in keeping your immune system strong.
Eye Health
Goji seeds benefits include protecting your eyes. The seeds contain zeaxanthin, a carotenoid that helps keep your vision sharp. In a study, adults who ate 28 grams of goji berries five times a week for 90 days had higher macular pigment optical density. This marker shows better eye health and a lower risk of age-related macular degeneration.
The same study found that skin carotenoid levels also increased, showing that goji seeds help your body absorb and use these important nutrients. Other research shows that goji polysaccharides boost antioxidant enzymes, which protect your eyes from damage.
Skin and Anti-Aging
Goji seeds have a long history in traditional medicine for promoting youthful skin and slowing signs of aging. The seeds contain antioxidants, vitamin C, minerals, and amino acids. These nutrients help keep your skin firm, hydrated, and protected from damage.
- Ancient Chinese texts mention goji seeds as a food for longevity and healthy skin.
- Lab studies suggest that antioxidants in goji seeds may help reduce wrinkles and keep your skin looking fresh.
While more scientific studies are needed, many people use goji seeds to support healthy, glowing skin.
Blood Sugar and Heart
Goji seeds benefits extend to your heart and blood sugar levels. Research shows that eating goji berries can help balance insulin and glucose in your blood. This helps keep your blood sugar steady and may lower your risk of diabetes.
A study with people who have type 2 diabetes found that daily goji berry intake reduced blood sugar and increased HDL (“good”) cholesterol. Another trial showed that adults over 50 who ate goji berries every day had higher HDL cholesterol and a lower risk of heart disease.
By adding goji seeds to your meals, you can support your heart and help manage your blood sugar.
