Also known as goji berry, wolfberry has become a popular health food and herbal supplement due to its exceptional nutritional profile and antioxidant properties. Native to Asia, this bright red berry has been used for centuries in traditional Chinese medicine to promote wellness and longevity. In this article, we’ll explore the science-backed benefits of wolfberry for immunity, vision, heart health, and more.
Nutritional Value of Wolfberry
Wolfberries are packed with nutrients that make them a nourishing superfood. Some of the main active components include:
Vitamin A - Wolfberries provide high levels of pro-vitamin A carotenoids like beta-carotene. These antioxidant compounds support healthy vision and immune function.
Vitamin C - With over 30 mg of vitamin C per 100g serving, wolfberries supply powerful antioxidant activity to strengthen immunity and protect cells.
Polysaccharides - Wolfberries contain bioactive carbohydrates called Lycium barbarum polysaccharides (LBPs) that enhance immune response and deliver antioxidant benefits.
Zeaxanthin - This yellow pigment boosts eye health, filters blue light, and guards against macular degeneration. Wolfberries have one of the highest concentrations of zeaxanthin.
Iron - Wolfberries provide iron to support healthy red blood cell production and oxygen transport. This mineral deficiency is common, especially in vegetarian diets.
Zinc - With nearly 2 mg of zinc per 100g serving, wolfberries can help maintain immune function, metabolism, DNA synthesis, and growth.
Essential Amino Acids - Wolfberries contain all 9 essential amino acids, making them a complete protein source. Amino acids support muscle building, energy, and overall health.
With this diverse array of vitamins, minerals, antioxidants, protein, and unique phytonutrients, wolfberries deliver a nutritionally-dense punch.
Antioxidant Properties of Wolfberry
Wolfberries' high antioxidant content is one of their primary advantages. Free radicals, which are produced by normal cell processes and have the potential to cause oxidative stress and damage if left unchecked, are neutralized by antioxidants. Wolfberries contain important antioxidants like:
Phenolic Acids Compounds like chlorogenic acid and caffeine have been shown to prevent lipid peroxidation and scavenge harmful reactive oxygen species.
Carotenoids Wolfberries are abundant in carotenoids that reduce oxidative damage, such as zeaxanthin, beta-cryptoxanthin, beta-carotene, and lycopene.
Polysaccharides - LBPs separated from wolfberries show critical in vitro disease prevention agent movement by supporting superoxide dismutase (Grass), glutathione peroxidase (GSHpx), and other endogenous cell reinforcements.
Vitamin C Wolfberries contain over 30 milligrams of vitamin C per 100 grams, which boosts immunity.
According to a study, the liver, heart, and kidneys of mice can produce more antioxidant enzyme activity when wolfberry polysaccharides are present. In clinical tests on people, wolfberry juice drinking has also been shown to increase blood superoxide dismutase activity by 8 to 15%. Antioxidant defense promotes general health through this defense.
Immune-Boosting Benefits of Wolfberry
Traditional Chinese medicine has long valued wolfberries for protecting the body against disease. Modern research is now revealing the immune-modulating properties of this superfruit. Specific ways wolfberry supports immunity include:
Enhancing Natural Killer Cell Activity - Human trials show wolfberry increases the cytotoxicity of NK cells, which defend against viruses.
Boosting Lymphocyte Proliferation - Wolfberries stimulate the proliferation of lymphocytes including T cells and B cells, key players in cell-mediated and humoral immunity.
Increasing Immunoglobulin Levels - Studies demonstrate wolfberry elevates levels of IgA, IgG, and IgM antibodies involved in immune defense.
Reducing Inflammation - Wolfberries exhibit anti-inflammatory activity by inhibiting the release of IL-6, TNF-a, and other pro-inflammatory cytokines according to cell studies.
Providing Antimicrobial Action - Test tube research indicates wolfberry powder extracts have antimicrobial effects against certain bacteria and viruses like influenza.
Through a combination of direct stimulation and antioxidant-mediated effects, wolfberries can support robust immunity against pathogens.
Vision and Eye Health Benefits of Wolfberry
Abundant antioxidants like zeaxanthin make wolfberries an excellent food for protecting vision health. Human research on wolfberry indicates:
Improved Visual Acuity - Clinical studies show wolfberry extracts enhance visual acuity and color discrimination in the retina.
Reduced Eye Fatigue - Consuming wolfberry juice daily for a week reduced subjective eye fatigue in a placebo-controlled trial.
Protected Retinal Cells - Wolfberry extracts reduced apoptosis and preserved photoreceptor cells in animal models of diabetic retinopathy and retinal degeneration.
Reduced Risk of Macular Degeneration - High zeaxanthin content filters blue light and guards the macula against oxidative damage that can lead to age-related macular degeneration.
Glaucoma Protection - The antioxidant and anti-inflammatory activity of wolfberries may help reduce intraocular pressure and protect retinal ganglion cells in glaucoma.
These vision-preserving effects can be attributed to the rich supply of carotenoids like zeaxanthin and lutein that accumulate in the eye.
Heart Health Benefits of Wolfberry
Emerging evidence indicates wolfberries may also protect cardiovascular health in various ways:
Blood Pressure Reduction - Human trials associate daily wolfberry juice consumption with significant decreases in systolic and diastolic blood pressure. Bioactive LBPs may help dilate blood vessels.
Cholesterol Lowering Effects - Animal research indicates wolfberry polysaccharides can lower total cholesterol, triglycerides, and LDL (bad) cholesterol while raising HDL (good) cholesterol.
Atherosclerosis Prevention - The antioxidant activity of wolfberries inhibits LDL oxidation involved in the development of atherosclerotic lesions in rodent studies.
Improved Blood Circulation - Wolfberries enhance microcirculation and blood flow to the brain and retina in rabbits according to preliminary studies.
Cardioprotective Effects - Wolfberry extracts reduced myocardial infarct size and improved cardiac function after ischemia/reperfusion injury in rats.
Via diverse mechanisms, wolfberries promote cardiovascular health and prevent age-related decline.
Is Wolfberry the Same as Goji Berry?
Wolfberry and goji berry refer to the same red-orange fruit of the Lycium barbarum and Lycium chinense shrubs. Goji is the more common name used in the West, while wolfberry is a more accurate translation of the Chinese name “gǒu qǐ.” So whether you see it labeled as wolfberry or goji berry, it refers to the same therapeutic shrub fruits.
Who Should Not Take Wolfberry?
Wolfberries are generally very safe, with few side effects reported. But some precautions are advised:
- Those on blood thinners like warfarin should avoid wolfberry due to potential interaction effects. Wolfberries contain small amounts of vitamin K which could interfere with anticoagulant medication.
- People with pollen or latex allergies should use caution, as cross-sensitivity is possible. Discontinue use if any hypersensitivity reaction occurs.
- Wolfberries may affect blood glucose levels, so diabetic patients should monitor closely when consuming large or consistent amounts.
- Excessive consumption may potentially interact with Cytochrome P450 enzymes, so patients on medication utilizing the CYP450 pathway should consult a doctor.
- As with any new food, introduce wolfberries gradually to assess individual tolerability. Seek medical advice for any concerning reactions.
In standard amounts, most healthy adults can safely consume wolfberries and enjoy their nutritious benefits. Monitor for interactions if taking other herbs or pharmaceuticals concurrently.
What is Wolfberry Powder Good For?
Wolfberry powder provides a convenient way to get a concentrated dose of the berry’s nutrition. To make the powder, whole wolfberries are dried, ground, and pulverized into a fine powder. This powder can be:
- Added to smoothies, oatmeal, yogurt, baked goods and other foods
- Stirred into juices, tea, milk, or water as an instant health drink
- Placed into capsules or tablets as a supplement
- Used in protein balls, energy bites, or nutrition bars
- Added to lotions, creams, or face masks for antioxidant skincare
