Creatine Supplements

Hey!

Can anyone answer a question for me?

When I was first diagnosed with Hypothyroidism one of the first thing my Dr asked me was if I was taking any creatine supplements, and I wasn't.....

It was never explained to me why he asked that, but I got the impression that had I said yes he would have told me to stop.

Anyone know what effect creatine supplementation has? Just it'd be bloody handy for my training!

Cheers

Mark

  • Markwhufc82, It doesn't seem to affect thyroid but shouldn't be taken if renal or liver function is impaired.

  • Hello Mark,

    Welcome to our forum.

    Creatine is thought to increase strength and muscle mass.

    Creatinine is a normal byproduct of muscle metabolism created by the bodies use of creatine that the kidneys excrete.  If you have low thyroid hormone the kidneys cannot perform at a normal rate and a decreased glomerular filtration rate (GFR) will result in a reduced clearance of creatine meaning creatinine levels will start to rise. This is bad news.

    The body's metabolism depends on the amount of hormones you have and good levels of T3 are required for exercise. T3 directly boosts metabolism in mitochondria & regulates fat, protein, and carbohydrate metabolism.

    Physical exercise will enhance thyroid production in a healthy person but also in hypothyroidism as long as you are optimally medicated and diet is right and the exercise is not too much.

    Don't forget heavy training might raise cortisol levels too high and commonly cause inflammation by overuse of certain muscles. Both of these can inhibit T4-T3 conversion and everyone requires good levels of T3 to function well ( let alone exercise intensely.)

    Whether you have good results from creatine or not is individual and down to genetics. One of my sons takes creatine (against my wishes but he is not hypothyroid) with juice which enhances muscle uptake as carbs are required.

  • Morning!

    Thank you both for your responses.

    That's very helpful Flower.

    I've previously trained using Creatine (years before being diagnosed) and I gained very good results particularly with regards to recovery rate, and muscle mass. The research conducted on creatine over the years confirms that it is possibly THE sports supplement to take (unlike the inconclusive research on things like protein supplementation).

    Since being diagnosed my level of exercise and fitness has increased significantly and thus far I've not had any problems. My job as an exercise therapist keeps me very active as well as my own personal regime. I take 175mg of levothyroxin a day which I'm led to believe is a hefty dosage and I'm as fit as I have been for some time. The reason I'm enquiring about creatine is just to assist a change in my exercise programme, but obviously I'm concerned about any side-effects or a return of any of the agonising symptoms I felt pre-diagnosis (cramps, bloatedness, fatigue etc...)

  • Mark,

    If you feel well that is great & medicating T4 alone obviously suits you as it does for most people..

    175mcg of Levo is a hefty dose but as long as your body is utilising it well, I don't think this matters.

  • I used to use when I was a body builder to help with muscle building. It helps eliminate fatigue when training by helping to create more ATP for energy (I missed out a few steps, but that's basically it.) Can be hard on your liver or kidneys if you already have a problem, but studies haven't shown that it actually damages them. If you take creatine, you'll probably show up a higher creatinine score on blood tests (which might be indicative of kidney damage if you weren't supplementing). that would be the most likely reason for the doc to ask you (esp if you are male and look as though you might spend time in the gym or be a athlete)

  • Hey man,

    Cheers for that, I might give my doctor a ring and see what he has to say.

    The training benefits of creatine are what's tempting. When I've supplemented it in the past I've felt great! Haha

  • Sorry to butt in here but what is wrong with a low creatinine level. ?Mines is 48 with range 44 to 80. You alla talk about building muscle but I find that mine are weak. My legs are heavy going up stairs and I have no strength in my hands either.

  • There is not usually anything wrong with having a low creatinine level.

    Please don't confuse creatine and creatinine - they are two different things.

    There is also a substance, different again, called creatine kinase which is measured when checking for muscle damage. It is tested in people who are suspected of having had a heart attack or rhabdomyolysis.

  • Yeah I'm not on about a low creatinine. Thanks for your reply though.

  • So sorry should put my glasses on.
