If you want to burn more fat
during your workouts then you need to increase your L-Carnitine levels.
L-Carnitine is an amino acid
that transports released fat to muscle to burn as energy. Depending on what you
read, I've seen recommendations that say to take between 1 gram to 12 grams of
l-carnitine per day.
The high end would become
very expensive. I've priced l-carnitine at about .18 cents per gram. L-Lysine
is priced at about .07 cents per gram. That's less than half the cost.
Why lysine? Because the body
converts it to carnitine. I was doing some research on precursors to some of
the more expensive amino acids the ran across the below study. Of course I like
to hedge my bets and still take carnitine pre and post workout.
Here's what I do:
1. I take 5 1,000 mg lysine tablets with any meal.
2. 500 mg to 1,000 mg carnitine pre and post workout.
3. Consider adding 250 mg to 1 gram of choline.
4. Add 500 - 1,000 mg of Vitamin C.
Stay Strong My Friends!

Lysine-carnitine conversion in normal and
undernourished adult men-suggestion of a nonpeptidyl pathway.
Abstract
Administration
of 5 g L-lysine orally to normal adults produced a significant increase in
plasma carnitine levels within 6 h followed by a further rise by 48 h. Levels
remained high up to 72 h. Similar changes in plasma carnitine were not observed
if blood was sampled without lysine load or after administering a load of other
amino acids such as tryptophan or threonine. Maximum excretion of carnitine per
g creatinine was observed in 24 to 48 h collection after lysine load. Two
subjects showed an early peak in 3-h and 6-h collections, respectively.
Undernourished subjects failed to demonstrate similar change. After
rehabilitation the undernourished subjects behaved as did the well-nourished
subjects. These observations suggest that there may be a rapid in vivo
conversion of orally administered lysine to carnitine in humans. Conversion of
lysine to carnitine may be impaired in malnutrition.
