"A single drop (1ml) provides 480mg DHA and 150mg EPA, the same as a whole tin of sardines. A handy dosing syringe is provided so it's easy to measure. This super fresh fish oil with just a little natural Sicilian lemon oil added is highly palatable, making it easier to give to children. One bottle can last up to 3 months, depending on dosage. Bare Biology have every batch certified and awarded a 5-star purity and quality rating from International Fish Oil Standards. This means the fish oils are completely free from heavy metals, PCBs and other nasties sadly found in polluted seas. Bare Biology only uses sustainable fish supplies of wild anchovy, sardines and mackerel and all the fish oils are in the natural triglyceride form for easy absorption and digestion."
