Should I take Creatine before or after my workout?
Seems like such an easy question - but as with most things,
nothing is ever that easy. The answer that is right most of the time is -
before your workout. However, the form of creatine (powder, liquid, gum, etc.)
you use affects the answer. In addition if you are taking a supplement that has
other ingredients in addition to the creatine - that can also play into the
answer. So - let's look at some more detail...
What do the scientific studies say about when to take
creatine?
Most of the studies involved giving volunteers powder
creatine monohydrate before a workout. If they were doing a loading phase it
was split into 4 servings (5 grams each) and these were given throughout the
day. Still other studies split the dosage even in the maintenance phase and
give half the creatine before a workout and the other half after.
How long does creatine stay in the blood stream?
When you take creatine in powder form - it is in your blood
stream for about 1 - 1.5 hours. For muscle growth the creatine must be absorbed
into the muscles. So, if you are working out and deplete your creatine supply
in your muscles AND you have creatine available in the blood stream, your
muscles can replenish their creatine supply from the creatine in your blood.
Here is the important point - if your muscles are fully
saturated with creatine and you are not working out ( so you are not depleting
your creatine stores) then after 1.5 hours the creatine in your blood will be
converted into creatinine and excreted.
So, with Creatine powder - should I take it before my
workout or after?
Here is our advice - take the powder about 1 hour before
your workout. Here is our reasoning...
It can take about 1 hour for the creatine to be absorbed
into the bloodstream - and from that point you have about 1.5 hours to use the
creatine or lose it. So, let's say you workout at 10am - here is our logic. At
9am you take the creatine powder. By 10am the creatine is in the blood stream.
Your muscles are probably mostly saturated with creatine from the supplement
you took the day before. So, some of the creatine you took at 9am may be
absorbed into the muscles - but the rest is still in the blood. At 10am you
start working out and depleting the creatine in your muscles. Your muscles then
replenish their creatine supply from the creatine in the blood stream. Your
workout ends at 11am (you really should not workout more than 1 hour - but that
is a topic for a different day). Remember, you took creatine at 9am - but it
was not absorbed into the blood stream until 10am. This means it will stay
there until 11:30am (1.5 hours). So, now you have another 1/2 hour where your
muscles can replenish their creatine supply if depleted. In a way you are
getting the best of all worlds - you have creatine available before, during and
after your workout.
You will hear other theories - but that is what we have
found to be most effective. Since creatine supplies us with energy when working
out - it is important we have creatine available during our workout. Creatine
as a recovery agent is much less clear, so taking it after a workout to help
with recovery is not proven.
Why does my bottle say take it after a workout?
Good question - there are a few reasons for that. The first
is that they have a different opinion than us on how creatine works. If this is
the case, I would call and ask them to explain exactly why they think after a
workout is better. A second reason is that your supplement has other
ingredients besides creatine. Many companies have tried to improve on creatine
by adding all types of other supplements. It may be that some of those other
supplements do much better if taken after a workout. After a workout is a great
time to take a protein supplement because your body is in a growth phase
(anabolic). Taking creatine after a workout is not a terrible idea - it is a
great time to get the creatine absorbed into the muscles. We just feel, it is
important to have creatine available to the muscles during your workout if
their creatine supply is depleted. Again, if the manufacturer can provide a
clear explanation of why to take it after a workout - fine.
What if I have been taking creatine after my workout?
Don't worry you have still been getting most the benefits of
creatine. What is probably happening is the creatine you take after your
workout on Monday is what your body will use during your workout on Tuesday. I
know - we said creatine only lasts 1.5 hours in the blood stream. However,
creatine can last for days once it is trapped within your muscles. So, the
creatine you take after your Monday workout is pulled into the depleted muscles
where it will stay for days until you use it up. The only problem is that if
you deplete your creatine stores during a workout you will not have any other
creatine available. This is why we think taking it before a workout is better.
What about liquid, serum, effervescent or creatine gum?
The body absorbs these forms of creatine more quickly. For
this reason, we still recommend taking them before a workout - but only about
20 minutes before a workout. Again, the creatine will stay in the blood stream
for up to 1.5 hours - but it will only take 20 minutes for the creatine to get
into the blood stream.
Should I take creatine on my off days?
Seems like a simple question - but it is very hard to get a
straight answer on this one. There is some evidence that indicates that
creatine can help with muscle recovery. If this is true, then taking creatine
on your off days is a good idea. Our feeling is that more research needs to be
done before anyone can conclusively say that creatine helps with recovery. This
research may not come anytime soon so you are left to make your own decision.
If you feel that creatine is helping with muscle recovery, then yes take it on
your off days. If you are not convinced that creatine helps with recovery, then
you do not need to take it on off days.
Many people believe that you need to take creatine everyday
to keep your creatine levels topped off. We do not see the research that proves
this to be true. If you are taking creatine for the muscular boost in energy,
that taking it just on workout days should be fine.
Want more facts to make this questions more confusing? A
University of Kentucky study shows that use of creatine could help the brain
recover from concussions and other injuries commonly suffered by professional
and amateur athletes (the study was published in the Annals of Neurology - 11/2000).
Brain damage was reduced 21% when creatine was given to mice three days before
injury and 36% when given five days ahead of time. Rats given a diet with
creatine for four weeks had 50% less brain damage than rats that did not
receive creatine. This may explain why pro football players can recover so
quickly from concussions - they take creatine.
So, if you play a contact sport you may want to take
creatine everyday for the possible prevention of brain damage. Of course, more
research needs to be done - but just another factor to consider when you decide
if you should use creatine on your off days.
