A simple electronic scale is very helpful and costs around $20. Most online supplement retailers offer inexpensive scales. Be sure to purchase one that measures in one-gram increments or less. If your daily dose is large, a powdered herb or supplement will usually be recommended. This is done to avoid consuming an excessive amount of capsules. All herbs and supplements are available in capsule form however. Most capsules come in 500 mg size so it is fairly easy to determine the amount of capsules to be consumed. Also keep in mind that 500 mg equals 1/2 gram and 1,000 mg equals 1 gram.
