Vitamin C Multi: What the Authorised EU Health Claims Actually Say

Vitamin C is one of the most researched nutrients, yet many supplements overlook the synergistic potential of whole-food botanicals and co-factors. Vitadefence Vitamin C Multi combines a potent 512 mg of vitamin C with a curated blend of baobab, aged garlic, turmeric, reishi mushroom, and more—plus zinc, vitamin D, selenium, and B6. This formula is designed to support normal energy metabolism, immune function, and protection of cells from oxidative stress, all within a single, easy-to-swallow capsule.

What is Vitamin C Multi?

Vitamin C (ascorbic acid) is a water-soluble vitamin essential for the synthesis of collagen, the maintenance of healthy skin, bones, and blood vessels, and the normal function of the immune system. The EU Register of Nutrition and Health Claims authorises the claim that "Vitamin C contributes to the protection of cells from oxidative stress." However, the body cannot produce or store vitamin C, so regular dietary intake—or supplementation—is necessary.

Vitamin C Multi goes beyond a simple ascorbic acid capsule. It incorporates 13 additional botanicals and minerals, each selected for its traditional use and complementary profile. The formula includes baobab fruit pulp (a natural source of vitamin C and fibre), aged black garlic (traditionally used to support circulation), and reishi mushroom (a revered adaptogenic fungus in traditional Chinese medicine). The inclusion of BioPerine (black pepper extract) is intended to enhance absorption of key constituents.

How the formula was designed

The Vitadefence formulation team took a whole-food–inspired approach. Rather than relying solely on synthetic vitamin C, the formula includes acerola cherry (a natural source of vitamin C and bioflavonoids) and baobab fruit pulp, which provides additional vitamin C along with soluble fibre and polyphenols. The inclusion of citrus bioflavonoids (25 mg) is based on research suggesting these compounds may enhance vitamin C absorption and retention (Vinson et al., 1995, Journal of the American College of Nutrition).

The mineral cofactors—zinc (5 mg), selenium (10 µg), and vitamin D (2.5 µg)—are added at moderate levels to complement the vitamin C. Zinc and selenium are both authorised for the claim "contributes to the normal function of the immune system." Vitamin B6 (1.5 mg) is included because it contributes to normal energy-yielding metabolism and the reduction of tiredness and fatigue. The BioPerine (2.6 mg) is a patented black pepper extract shown in clinical studies to increase the bioavailability of curcuminoids and other nutrients (Shoba et al., 1998, Planta Medica).

The science — what's well-supported

Vitamin C and immune function: The European Food Safety Authority (EFSA) has confirmed that vitamin C contributes to the normal function of the immune system and to the protection of cells from oxidative stress. A systematic review by Hemilä and Chalker (2013, Cochrane Database of Systematic Reviews) found that regular vitamin C supplementation (≥200 mg/day) reduced the duration of common cold episodes in adults by 8% and in children by 14%. The 512 mg dose in this product is well within the range used in those trials.

Zinc and immune defence: Zinc is a trace mineral essential for the development and function of immune cells. A meta-analysis by Singh et al. (2011, Cochrane Database of Systematic Reviews) reported that zinc lozenges (≥75 mg/day) shortened cold duration, though the 5 mg dose here is lower and intended for daily maintenance, not acute therapy.

Elderberry and respiratory support: Black elderberry has a traditional use for the relief of cold and flu symptoms. A randomised controlled trial by Tiralongo et al. (2016, Nutrients) found that elderberry extract (300 mg/day) reduced the duration and severity of cold symptoms in air travellers. The 15 mg in this formula is a smaller, supportive dose.

Turmeric and oxidative stress: Curcumin, the active compound in turmeric, has been studied for its antioxidant properties. A review by Hewlings and Kalman (2017, Foods) noted that doses of 500–2,000 mg of curcumin are typically used in clinical trials, but the 36 mg of turmeric root extract here is intended as a complementary botanical rather than a standalone therapeutic dose.

Garlic and cardiovascular health: Aged black garlic has been studied for its potential to support healthy blood pressure and cholesterol levels. A meta-analysis by Ried et al. (2016, Journal of Nutrition) found that garlic supplements (600–900 mg/day) reduced systolic blood pressure by 8–9 mmHg. The 50 mg here is a smaller inclusion, meant to complement the overall formula.

How to take it

The recommended dosage is 1 capsule, 1 to 3 times per day or as advised by a healthcare professional. Given that each capsule contains 512 mg of vitamin C, taking 2–3 capsules per day would provide 1,024–1,536 mg, which is within the safe upper limit of 2,000 mg/day for adults set by the European Food Safety Authority (EFSA).

For best absorption, take the capsules with a meal, especially one containing some fat (the vitamin D and E are fat-soluble). If you experience digestive discomfort, reduce to 1 capsule per day and increase gradually.

Storage

Store in a cool, dry place, out of direct sunlight and away from moisture. Keep the lid tightly closed after each use. Do not use if the seal is damaged. The best before date is printed on the base of the pot. As with all supplements, keep out of reach of children.

Allergen and dietary information

This product is suitable for vegetarians and vegans. It is Kosher approved and Halal approved. The capsule shell is made from HPMC (hydroxypropyl methylcellulose), a plant-based alternative to gelatin. The brown rice flour used as a filler is gluten-free. No artificial colours, flavours, or preservatives are added.

Allergen note: While the product itself does not contain common allergens (milk, eggs, fish, crustaceans, tree nuts, peanuts, wheat, soy, or sesame), it is manufactured in a facility that also handles these ingredients. If you have a severe allergy, please consult the manufacturer.

Who should be cautious

Although Vitamin C Multi is formulated with safe, moderate doses, certain individuals should exercise caution:

• Pregnant or breastfeeding women: The vitamin A (none here) and high-dose vitamin C may be a concern. The 512 mg dose is below the 2,000 mg upper limit, but always consult your midwife or doctor.
• People with kidney stones: High-dose vitamin C (above 1,000 mg/day) may increase oxalate excretion and the risk of calcium oxalate kidney stones in susceptible individuals. If you have a history of stones, consult a healthcare professional before taking this product.
• Those on blood-thinning medication: Vitamin E (5 mg) and aged garlic may have mild antiplatelet effects. While the doses are low, it's wise to discuss with your doctor if you take warfarin or other anticoagulants.
• Individuals with haemochromatosis: Vitamin C can increase iron absorption, which may be problematic for those with iron overload disorders.

What pairs well with Vitamin C Multi

For a more targeted approach to immune and skin health, consider pairing Vitamin C Multi with Acerola Multi, a whole-food vitamin C supplement made from acerola cherry. While Vitamin C Multi is a comprehensive blend, Acerola Multi offers a higher dose of natural vitamin C (1,000 mg per serving) with added bioflavonoids, and can be taken on alternate days or alongside it for additional support.

Frequently asked questions

1. Can I take Vitamin C Multi every day?

Yes. The formula is designed for daily use. The recommended dose is 1 capsule 1–3 times per day. The 512 mg of vitamin C per capsule is well within safe limits, and the other nutrients are present at moderate levels suitable for long-term supplementation.

2. Is this product suitable for children?

This product is formulated for adults. The vitamin C and zinc levels exceed the NRV for children. For children aged 4–12, we recommend consulting a paediatrician for appropriate dosing. For teenagers, a lower dose (e.g., 1 capsule per day) may be acceptable, but professional advice is advised.

3. What is the role of BioPerine in this formula?

BioPerine is a patented black pepper extract standardised to 95% piperine. Clinical studies have shown that piperine can increase the bioavailability of certain nutrients, including curcumin (by up to 2,000%) and selenium. In this formula, it is included to support the absorption of the botanical extracts, particularly turmeric and olive leaf.

4. Can I take this with other supplements?

Generally, yes. Vitamin C Multi is compatible with most multivitamins and mineral supplements. However, because it already contains vitamin D (2.5 µg), vitamin E (5 mg), zinc (5 mg), and selenium (10 µg), be mindful not to exceed the upper safe limits of these nutrients if you take additional supplements. For example, the upper limit for zinc is 25 mg/day, so you have room for extra zinc if needed.

5. Does this product contain caffeine or stimulants?

No. The botanicals in this formula—baobab, acerola, turmeric, reishi, elderberry, etc.—do not contain caffeine. The cayenne pepper (20 mg) contains capsaicin, which is not a stimulant in the same class as caffeine, though it may cause a mild warming sensation.

6. How long does one pot last?

Each pot contains 60 capsules. At the recommended dose of 1 capsule per day, one pot will last 60 days (2 months). At 3 capsules per day, it will last 20 days. We recommend starting with 1 capsule per day and adjusting as needed based on your individual requirements.
