Turmeric can also be used on skin! One of my favorite ways to use it is in a face mask. You can add 1/2 teaspoon of turmeric powder to any face mask recipe you love. My favorite recipe: Mix 2 tablespoons of unsweetened yogurt with 1/2 teaspoon of turmeric and 1 teaspoon of honey for a soothing and cooling face mask.
The minimum dosage for lysine is 850 milligrams per day for an adult. The therapeutic dosage may be up to 3 grams per day. The recommended daily allowance (RDA) for adults is 10 milligrams for every pound of body weight. So for an adult of 200 pounds, the dosage would be 2,000 milligrams, or 2 grams per day. This is a recommended daily dose for lysine; a therapeutic dose may be higher.

By the book, 3200 mg per day is the maximum safe dose.
