(Updated 3 April 2013)
A good diet of healthy foods can be augmented by purchasing dietary supplements which provide additional vitamins, minerals, herbal extracts, and antioxidants.
I have been taking large doses of dietary supplements since 1982, and modifying the doses as I learn more, in my ongoing self-experimentation program.
Note: Optimal supplement dose probably varies with age, weight, gender, and genetic background, as well as the foods eaten. I am a male, 140 lb, born in the 1950's.
Table 1, below, lists the supplements I currently take every day, in addition to a well-designed vegetarian diet.
Table 2, below, lists additional supplements I take when fighting off infectious illness.

  • A - Age-related dose. Younger people take less.
  • B - Bedtime. Take when going to sleep.
  • M - For men. Not for women.
  • CW - Fish that live in cold water, such as salmon have the best omega-3 oils.
  • E - Should be taken on an empty stomach, once per day.
  • F - Absorption is best when consumed with food.
  • FF - Absorption is best when consumed with food containing fats or oils.
  • P - For best absorption, do not consume protein for 1 hour before or after taking this amino acid.
  • I - I increase this dose when fighting off infectious illness.
  • S - Smaller amounts spaced every hour or two.
  • T - Brewed in boiling water with tea.
  • X - Caution: Do not exceed this dose.
  • mg is milligram. 1 milligram = 0.001 gram.
    1 microgram = 0.000001 gram = 0.001 mg.
  • These quantities should not be taken by children, nor by pregnant or lactating women. When in doubt, reduce the dose and consult a knowledgeable professional.
  • Start gradually. When starting on supplements, start out with much smaller doses (about 1/10 of the amounts listed here) and gradually work up over a period of weeks to give your body time to adjust.
  • Where convenient, these daily doses are divided into several parts. Spreading the dosage throughout the day helps to maintain a consistently high level of supplements in the bloodstream.
  • It is worth remembering that individual people may differ somewhat in their needs and in their ability to assimilate various foods and supplements. It is important to pay attention to your own body as you experiment with your diet and lifestyle.

Powders, Pills, Capsules, and Liquids

In my quest to attain nutritional supplements at reasonable cost, I have been purchasing different items from different suppliers, who are listed below. Some items are in the form of bulk powders which can be combined and taken at the same time. Others are in the form of tablets, capsules, or liquids. Details of how I mix the powdered supplements are described in my report, below.

Additional Information:

I have compiled a detailed, 30-page report, "Nutrition, Diet, and Supplements for Peak Physical & Mental Performance." In it, Detailed descriptions are provided for each ingredient, with references to a bibliography of 40 books and journal articles. It also lists reasonably-priced sources of quality ingredients, suggests how to mix them, and the best times of day to take them. Additional information is provided on proteins, amino acids, fats, carbohydrates, and hormones. [ Click here to view the PDF. ==> furbernutrition.pdf ]
