The oil used comes exclusively from wild cod fished in the cold waters near the Arctic, an area free of industrial pollution. Fishing follows sustainable, eco-responsible practices to preserve marine resources. Extraction is carried out at low temperature to protect the fatty acids and vitamins naturally present in the liver, and activated-carbon filtering removes impurities and residual oxidants without altering the nutritional profile — a traditional process enhanced by modern technology for remarkable freshness and purity.

Each 2-capsule serving provides 2.5 micrograms of vitamin D (100 IU) and 180 micrograms of vitamin A as retinol equivalents. Vitamin D contributes to the normal function of the immune system and helps fix calcium in bones and teeth. Vitamin A supports vision, cell structure and the body’s natural defences. These two fat-soluble vitamins work together to reinforce daily protection, particularly during periods of reduced sun exposure.

Dynveo Cod Liver Oil provides 200mg of total omega-3 per serving, including 80mg EPA and 90mg DHA. These long-chain polyunsaturated fatty acids play a recognised role in normal heart and brain function. DHA contributes to maintaining normal brain function and normal vision, while EPA supports cardiovascular function and the balance of the body’s natural inflammatory processes. The capsule format eliminates the fishy aftertaste that put many consumers off traditional liquid cod liver oil.

Recommended dose is 2 capsules a day, i.e. 1g of pure cod liver oil, suitable for adults and older children with dosage adjustable to individual needs under professional advice. Winter is a favoured time to start a course, though supplementation can be considered year-round depending on needs.

At the recommended dose of 1 to 2 capsules a day, no excess vitamin A is expected in a healthy person. Caution is advised for pregnant women and those taking other vitamin A sources at the same time. Food supplement. Not a substitute for a varied, balanced diet and a healthy lifestyle. Do not exceed the recommended daily dose. Keep out of reach of children.

Is there a risk of vitamin A overdose with cod liver oil?

At the recommended dose of 1 to 2 capsules a day, no excess is to be feared for a healthy person. Vigilance is advised for pregnant women and for anyone combining multiple vitamin A sources at once. Always follow the stated dosage and consult a healthcare professional if in doubt.

How long before noticing the first benefits?

Effects on general vitality and immunity are usually noticeable after 4 to 6 weeks of regular use, alongside a varied, balanced diet. Consistency in supplementation is key to lasting results, and each person responds differently, so patience is advised.
