Bilberry - Vaccinium FAQ

Do you sell Bilberry (Vaccinium uliginosum)?

We sell Vaccinium in various sizes in our online store. We also sell all-natural Bilberry herbal extract in a 50-serving boxed size as SAVVY! Brain Health Support.

In addition, Vaccinium uliginosum is one of five nootropic extracts in our BrainStorm Nootropic Brain Health Kits. (The other extracts are Cistanche, Haritaki, Polygala tenuifolia, and Semen cuscutae.)

What are the health benefits of Bilberry?

Bilberry is a powerful nootropic, an adaptogen, and an antioxidant. It’s highly valued for its healing and rejuvenating powers, and it’s used to support treatment for a variety of chronic diseases and everyday ailments.

Bilberry health benefits include antioxidant, genoprotective, antitumorigenic, anti-inflammatory, hypoglycemic, and antimicrobial effects. It promotes a healthy heart, healthy eyes, healthy skin, healthy muscles, and brain health. Among many other uses, it is recognized as a possible tool to combat chronic and infectious diseases in aging populations.

Bilberry is valued for its healing and rejuvenating powers. Some people call it the brain berry because of the support it provides for brain health. Therapeutic uses include strengthening and nourishing the joint tissues. It is also used to support the proper function of the colon, lungs, liver, and spleen. Vaccinium offers a broad spectrum of support, which is why we believe it’s a valuable health supplement.

What are other health benefits of Bilberry?

Chapter 4 of Herbal Medicine says: “Bilberry … is one of the richest natural sources of anthocyanins. These polyphenolic components give bilberry its blue/black color and high antioxidant content, and they are believed to be the key bioactives responsible for the many reported health benefits of bilberry and other berry fruits.

“Although bilberry is promoted most commonly for improving vision, it has been reported to lower blood glucose, to have anti-inflammatory and lipid-lowering effects, and to promote antioxidant defense and lower oxidative stress. … [B]ilberry is of potential value in the treatment or prevention of conditions associated with inflammation, dyslipidemia, hyperglycemia or increased oxidative stress, cardiovascular disease (CVD), diabetes, and dementia and other age-related diseases.”

Bilberry interacts with the respiratory, circulatory, digestive, nervous, renal, and integumentary body systems. Today, it’s generally recognized that it supports a whole healthy lifestyle approach and offers a wide range of health-related properties, including antioxidant, anti-tumorigenic, anti-inflammatory, hypoglycemic, and antimicrobial effects.

Is it a nootropic? Can it support memory and cognition as we age?

Bilberry is often considered a nootropic botanical because of growing interest in its potential to support memory, learning, circulation to the brain, and healthy cognitive function. Its anthocyanins and other polyphenols provide strong antioxidant activity, which may be particularly relevant to the brain because brain tissue is vulnerable to oxidative stress.

Research involving Bilberry and other anthocyanin-rich berries has explored potential benefits for memory, executive function, processing speed, and other aspects of cognition, particularly in older adults. Researchers are also investigating how berry polyphenols may support neuronal signaling, vascular function, and the brain’s defenses against oxidative and inflammatory stress.

The evidence does not establish Bilberry as a treatment for cognitive impairment or demonstrate that it can reverse age-related cognitive decline. Instead, Vaccinium uliginosum is best viewed as a nutrient- and polyphenol-rich botanical that may help support brain health and cognitive resilience as part of a broader healthy-aging lifestyle.

Vaccinium is also one of five nootropic extracts in Linden Botanicals’ BrainStorm Nootropic Brain Health Kits. 

Can it help relieve stress?

It helps maintain the balance of the central nervous system when you’re under stress. Some evidence suggests that the extract protects the brain from the effects of stress.

What are its antimicrobial properties?

Vaccinium uliginosum has shown antimicrobial properties against Fusobacterium nucleatum and Streptococcus mutans. This antibacterial activity is attributed to flavonoid glycosides and anthocyanins. These findings make Vaccinium uliginosum an interesting source of naturally occurring antimicrobial compounds and an area worthy of continued research, but Bilberry should not be considered a replacement for antibiotics when medical treatment is needed.

Can it help lower the risk of oxidative stress?

Vaccinium uliginosum may lower the risk of oxidative stress-related disease.

Can it lower insulin resistance?

Researchers have investigated its potential in lowering insulin resistance. It may also support lowering the risk of type 2 diabetes and help to better control type 2 diabetes.

Polyphenols have exhibited anti-diabetic activities against diabetic-causing enzymes. They can inhibit enzymes such as glucohydrolase enzymes, α- amylase, β-glucosidase, and α-glucosidase. Anthocyanins may also reduce glycosuria, glycated hemoglobin, and blood glucose, as well as increase the secretion of insulin and lower the rate of sugar absorption in the small intestines.

Can it support healthy vision and sensory input?

Studies suggest it can help preserve healthy vision. It helps prevent diabetic retinopathy, which is disease of the retina that results in impairment or loss of vision. It is widely used to improve night vision and decrease vascular permeability and capillary fragility. Vaccinium extract may be able to protect against blue light damage and eye strain resulting from computer and tablet use.

A 2019 study published in Molecular Vision highlights the possibility that Vaccinium uliginosum (Bilberry, Bog Blueberry) may show a preventive effect against cataract formation. These results suggest that Vaccinium uliginosum may exert a therapeutic effect on age-related cataract.

Vaccinium uliginosum contains glycosides, anthocyanins, organic acids, and polyphenols. Flavonoids and anthocyanins in berry crops have long been investigated for their ocular benefits, such as retinal cell protection, neuroprotection, night vision, and visual pigment function, berry crops (including bog bilberry). Vaccinium uliginosum is commonly consumed to support vision as an eye health supplement.

How about inflammation?

It may lower the risk of inflammation-related disease.

Can it lower blood pressure?

It may help lower blood pressure, improve lipids, and lower the risk of cardiovascular disease and stroke.

What digestive support does it provide?

It may promote healthy digestion. It has been used as an antidiarrhoeal. The effectiveness of Bilberry extract against enteric viruses may be the source for its traditional use to help stop diarrhea. It is regarded in traditional systems as being useful for constipation, irritable bowel system, flatulence, ulcers, vomiting, intermittent fever, kidney stones, and hemorrhoids. It maintains regular elimination, helping to clear accumulated toxins in the gut.

Does it support heart health and circulation?

It is often used as a heart tonic. This traditional use has been supported by a number of studies. Benefits from the anthocyanin and polyphenol antioxidants in blueberries are seen in healthy subjects and in those with existing metabolic risk factors. Underlying mechanisms for these beneficial effects are believed to include upregulation of endothelial nitric oxide synthase, decreased activities of carbohydrate digestive enzymes, decreased oxidative stress, and inhibition of inflammatory gene expression and foam cell formation.

What are its skin health benefits?

Vaccinium has the potential to alleviate immune system-related skin disorders and the ability to protect the skin against UV light photoaging.

Is Vaccinium Included in BrainStorm Brain Health Support Kits?

Among the five powerful botanicals in our BrainStorm Brain Health Support Kits, Vaccinium uliginosum (Bilberry) stands out for its remarkable cognitive and eye health benefits. Rich in anthocyanins, bilberry supports blood flow to the brain, helping sharpen focus, improve memory, and protect against age-related cognitive decline. Its potent antioxidant properties also shield brain cells from oxidative stress, a key factor in neurodegeneration.

Bilberry is equally renowned for supporting vision. From strengthening retinal function to enhancing night vision and reducing eye strain, it provides broad-spectrum support for long-term eye health. When combined with the other botanicals in BrainStorm Kits, bilberry helps create a comprehensive, science-backed formula for mental clarity, cognitive resilience, and whole-body vitality.

What are the plant’s traditional uses?

Bilberry has long been a staple in the medical traditions of the Inuit and other first nations tribes of North America. The berry is also ethnomedically important to the people of the Caucasus mountains.

The Cree and other Native American nations consumed blueberry to improve night vision. Other traditional uses include drinking a tea from the leaves as an antidiarrhoeal, drinking the juice as a heart tonic, and consuming the berries to enhance endurance. Modern research supports these traditional uses.

Can I take Bilberry every day?

Bilberry can be incorporated into a regular wellness routine when used according to product instructions. Its naturally occurring anthocyanins and other polyphenols make it particularly interesting for ongoing support of brain health, vision, circulation, antioxidant defenses, and healthy aging.

Linden Botanicals’ Vaccinium uliginosum extract is naturally caffeine-free and can be mixed into water, juice, tea, or a smoothie. For many of the areas associated with Bilberry, including cognition and long-term eye health, consistent use makes more sense than thinking of it as something to take only occasionally. As with any botanical supplement, people taking prescription medications or managing a medical condition should discuss regular use with their healthcare provider.

How long does Bilberry take to work?

Bilberry is best viewed as a botanical for ongoing support rather than an immediate cognitive or vision boost. Its anthocyanins and other polyphenols support antioxidant defenses, circulation, and cellular health, processes that are generally more relevant to consistent, long-term wellness than to producing a noticeable effect after a single serving.

How quickly someone notices a difference will also depend on why they are taking Bilberry. Research into berries and berry-derived anthocyanins has examined outcomes ranging from vascular function and eye health to memory and cognition over varying periods of time. Individual responses differ, so consistency is generally more important than expecting an immediate result.

What makes Vaccinium uliginosum different from blueberries and other Bilberries?

Vaccinium uliginosum, sometimes called Bog Bilberry or Bog Blueberry, belongs to the same Vaccinium genus as blueberries, cranberries, huckleberries, and other closely related berries. These plants share many beneficial compounds, particularly anthocyanins and other polyphenols, but they are not botanically or chemically identical.

Different Vaccinium species can vary in their concentrations and combinations of anthocyanins, flavonoids, phenolic acids, and other phytochemicals. Geography, soil, climate, harvest timing, and processing can create additional differences. Linden Botanicals specifically identifies our extract as Vaccinium uliginosum because botanical identity matters. We don’t assume that every dark-blue berry or every product marketed as “Bilberry” is interchangeable.

Why are anthocyanins in Bilberry so important?

Anthocyanins are natural plant pigments responsible for the deep blue, purple, and red colors found in Bilberries and many other fruits. They are also potent polyphenol antioxidants and are among the compounds most closely associated with Bilberry’s potential health benefits.

Bilberry anthocyanins have been studied for their relationship with brain health, retinal and eye health, circulation, blood-vessel function, inflammatory balance, and protection against oxidative stress. These areas are interconnected. The brain and eyes, for example, both depend on healthy circulation and are particularly susceptible to oxidative stress as we age.

This rich anthocyanin profile helps explain why Bilberry can have relevance well beyond vision alone. It is one of the reasons Linden Botanicals values Vaccinium uliginosum as both a brain-health botanical and a broader healthy-aging supplement.

How did you choose your Bilberry supplier?

For each of the products we sell, company owner Michael Van der Linden and members of our team do substantial research, visit the source, and meet with the collectors and processors personally. We back up our faith in our source and our processors with testing.

What does the plant look like?

Vaccinium is the Latin word for “blueberry” or “whortleberry.” Uliginosum means “full of moisture” or “marshy.” Bilberry is a perennial plant of the heather family (Ericaceae). It is closely related to the blueberry, cranberry, and huckleberry. The plant has many green, triangular, erect stems and flat, jagged, oval leaves. The urn-shaped flowers are pale pink or reddish in color.

The herb is native to naturally cool temperate areas such as the Northern Hemisphere, the Alps, Europe, Japan, Northern China, and Mongolia. It grows well on acidic soils and grows up to between 10 and 75 cm tall.

How do I consume Bilberry extract?

You can mix 1/2 teaspoon with 1 teaspoon honey, add the mixture to warm water, and drink it as a tea.

Add 1/2 teaspoon of extract to 8 oz of cool water, a cup of juice, a brain health smoothie, a concentration smoothie, or a stress relief smoothie. Stir until dissolved. Drink 1-3 servings a day.

Our team also developed a simple and healthy memory boost smoothie recipe to support nootropic brain health — particularly improved memory. These smoothies are blended drinks of fresh fruits, dark leafy greens, supplements, and Vaccinium extract that can help you improve your memory while also energizing you and transforming your body from the inside out. Best of all — they taste great!

Does Bilberry have caffeine?

No.

What flavonoids, anthocyanins, and polyphenols does it include?

Great question! First, let’s break it down. Flavonoids are plant metabolites thought to provide health benefits through cell signalling pathways and antioxidant effects. Anthocyanins are a type of flavonoid — a class of compounds with antioxidant effects. Polyphenols are micronutrients packed with antioxidants and potential health benefits. It’s thought that polyphenols may improve digestion issues, weight management difficulties, diabetes, neurodegenerative disease, and cardiovascular diseases.

Bilberry flavonoids include flavone (luteolin), flavonols (rutin, myricetin, Myricetin-3-O-galactoside, quercetrin, laricitrin, syringetin,kaempferol, isorhamnetin and quercetin, and quertectin-3-O-galactoside), and flavanols (gallocatechin, epigallocatechin, catechin, and catechin gallate).

Its anthocyanins include anthocyanidins (malvidin-3-galactoside, malvidin-3-glucoside, and cyanidin, delphinidin, petunidin, peonidin, and arabinose).

Its polyphenols include pterostilbene, resveratrol, ellagic acid, phlorizin, naringin and kaempferol.

Where can I learn more about Bilberry and other nootropic herbs?

Bilberry is just one of many botanicals being studied for their potential to support memory, learning, concentration, mental clarity, and long-term brain health. Its anthocyanins and other polyphenols make Vaccinium uliginosum particularly interesting for supporting healthy circulation, antioxidant defenses, and cognitive resilience.
