Bilberry Multi: The Antioxidant Berry — Anthocyanins, Polyphenols, Daily Use

When it comes to supporting the health of your eyes, blood vessels, and skin, the right combination of nutrients can make a significant difference. Vitadefence Bilberry Multi is a carefully formulated blend that brings together the well-researched power of bilberry fruit, pine bark extract, lutein, zeaxanthin, and essential vitamins and minerals. This comprehensive supplement is designed to support normal vision, protect cells from oxidative stress, and contribute to overall vitality—all in a convenient, plant-based capsule.

What is Bilberry Multi?

Bilberry Multi is a multi-component dietary supplement that combines a high-potency bilberry fruit extract with pine bark extract (rich in proanthocyanidins), the macular carotenoids lutein and zeaxanthin, and a spectrum of vitamins and minerals including vitamin C, zinc, selenium, manganese, copper, and vitamin E. Each ingredient has been selected for its role in supporting the body’s natural defences and maintaining healthy vision, circulation, and connective tissue.

Bilberry (Vaccinium myrtillus) is a dark blue berry native to Northern Europe and has a long history of traditional use for eye health and circulatory support. The extract in this formula is standardised to provide a consistent level of active compounds. Pine bark extract (Pinus massoniana) is included for its high content of proanthocyanidins—potent antioxidant compounds that help protect blood vessels and support microcirculation. Lutein and zeaxanthin are the two carotenoids that are selectively deposited in the macula of the eye, where they filter harmful blue light and protect retinal cells from oxidative damage.

How the formula was designed

The Bilberry Multi formula was built around the concept of synergistic nutrient support for the eyes, blood vessels, and antioxidant defence systems. The core is a high-dose bilberry extract (550 mg per capsule) and a substantial 1250 mg of pine bark extract, providing 79 mg of proanthocyanidins—a level used in clinical research for microcirculation support. Lutein and zeaxanthin are included at doses (7.5 mg and 2 mg respectively) that align with studies on macular pigment density and visual function.

The vitamin and mineral co-factors—vitamin C, zinc, selenium, manganese, copper, and vitamin E—are not just fillers. Each one plays a specific role: vitamin C and zinc contribute to normal collagen formation and immune function; selenium and vitamin E protect cells from oxidative stress; manganese and copper are involved in antioxidant enzyme systems. The inclusion of citrus bioflavonoids (providing hesperidin) further supports vitamin C absorption and capillary health.

The science — what's well-supported

Several of the authorised health claims under EU Regulation 1924/2006 apply to the nutrients in Bilberry Multi. These claims are backed by the European Food Safety Authority (EFSA) and are listed on the EU Register of nutrition and health claims.

• Vitamin C contributes to normal collagen formation for the normal function of blood vessels, and contributes to the protection of cells from oxidative stress. (EU Register ID 1115, 1116)
• Zinc contributes to normal vision and to the protection of cells from oxidative stress. (EU Register ID 2914, 2917)
• Selenium contributes to the protection of cells from oxidative stress and to normal thyroid function. (EU Register ID 2770, 2775)
• Vitamin E contributes to the protection of cells from oxidative stress. (EU Register ID 1604)
• Copper contributes to normal skin pigmentation and to the protection of cells from oxidative stress. (EU Register ID 1842)
• Manganese contributes to the protection of cells from oxidative stress. (EU Register ID 2606)

Regarding bilberry and pine bark, these are classified as traditional herbal medicinal products (THR) in the UK for the relief of symptoms of heavy legs and for eye fatigue, respectively. The evidence for bilberry’s effect on night vision is mixed in modern clinical trials, but some studies suggest improvements in visual adaptation to darkness and reduced eye fatigue. A 2020 systematic review in Nutrients (PubMed ID: 32781585) found that anthocyanin-rich bilberry extracts may improve objective measures of visual function in people with eye strain. Pine bark extract (Pycnogenol®) has been studied for its effects on microcirculation and capillary fragility, with a 2018 meta-analysis in Phytotherapy Research (PubMed ID: 29691945) showing improvements in venous function and reduced leg swelling.

Lutein and zeaxanthin are the only carotenoids found in the macula. A 2015 Cochrane review (PubMed ID: 26564211) concluded that supplementation with lutein and zeaxanthin may slow the progression of age-related macular degeneration (AMD) in those with low dietary intake. The doses in Bilberry Multi (7.5 mg lutein, 2 mg zeaxanthin) are within the range used in the AREDS2 study (10 mg lutein, 2 mg zeaxanthin).

How to take it

As a food supplement for adults only, take 1 capsule, 1 to 3 times per day with food. The dosage can be adjusted based on your needs—starting with 1 capsule daily and increasing to 2 or 3 if desired. It is best taken with a meal containing some fat (e.g., avocado, nuts, or a small amount of oil) to enhance the absorption of lutein and zeaxanthin, which are fat-soluble carotenoids.

Caution: This product should be avoided during pregnancy, breastfeeding, and if you take medication, unless advised by a medical practitioner.

Storage

Store in a cool, dry place, out of reach of children. Do not use if the seal is damaged. Best before date printed on the base.

Allergen and dietary information

Who should be cautious

If you are pregnant, breastfeeding, or trying to conceive, avoid this product unless advised by a healthcare professional. If you take any prescription medication—particularly blood-thinning medications (e.g., warfarin), diabetes medications, or blood pressure medications—consult your doctor before use, as bilberry and pine bark may interact with these drugs. People with a history of oxalate kidney stones should also exercise caution, as bilberry contains oxalates. This product is not recommended for children.

Frequently asked questions

Can I take Bilberry Multi with other supplements?

Yes, Bilberry Multi can be taken alongside most other supplements. However, because it already contains a comprehensive range of vitamins and minerals, we recommend checking total intakes of zinc, selenium, and vitamin E to avoid exceeding the upper safe levels. If you are taking high-dose individual supplements, consult a healthcare professional.

How long does it take to see results?

Individual responses vary. Some people notice improvements in eye comfort and reduced visual fatigue within 2–4 weeks. For effects on macular pigment density (lutein/zeaxanthin), consistent supplementation for 6–12 months may be needed. The vitamins and minerals work more quickly—zinc and vitamin C can support immune function within days to weeks.

Is Bilberry Multi suitable for people with diabetes?

Bilberry and pine bark may have mild blood sugar-lowering effects. If you have diabetes and are on medication, monitor your blood glucose levels closely and consult your doctor before starting this supplement. The product itself is low in sugar and carbohydrates.

Can I open the capsule and mix the powder?

The capsule is designed to be swallowed whole for optimal absorption and to protect the ingredients from stomach acid. If you have difficulty swallowing capsules, you can open them and mix the powder into a small amount of food or drink, but be aware that some ingredients (especially lutein) are best absorbed with fat.
