Nature's Answer Milk Thistle Seed is a 900mg fluid extract that is alcohol free. Nature's Answer alcohol-free extracts are made by eliminating the alcohol from the extract using our cold Bio-Chelated patented extraction technique, which results in a Holistically Balanced standardized extract. Liquid extracts are more potent than tinctures and are absorbed faster than pills or capsules. Holistically balanced ensures that the extract's elements have the same synergistic ratios as the plant. INGREDIENTS: purified water, glycerin, milk thistle seed extract (Silybum marianum, 150mg/ml). HOW TO USE: A daily dose of 1 to 2 milliliters (28 to 56 drops) diluted in 100 milliliters of water yields 150 mg to 300 mg of Milk Thistle seed extract. If required, you can up the dosage to 1 to 2 milliliters up to three times per day. A daily maximum dosage of 450 mg to 900 mg is provided. Don't take more than the suggested daily amount.
