Anyone use L-Carnitine? Does it work? Does it help?

I can't find the source I mentioned, but this explains the suspected correlation between uric acid levels and low carnitine levels.

In spontaneously hypertensive rats, L-carnitine decreases serum UA levels and the age-dependent rise in serum UA [31],[32]. Kidneys absorb 95% of carnitine from the glomerular filtrate via an active Na+-dependent transport mechanism [33]. Impairment of this reabsorptive function can lead to carnitine deficiency, in which hyperuricemia may be present because carnitine competes for renal tubular excretion

Interestingly, at least two patents have been applied for for potential treatments for gout, based on L-carnitine.

Hello Andy,

Please share thalassemia patients who needs regular transfusion L-Carnitine help them to increase HB level or only for other health benefits ?

L-carnitine has many benefits. It is a good antioxidant that helps blood last longer and also helps protect the body from the damage that free radicals do. It also helps to fix nitric oxide in the body, which is very important for the heart and circulatory system. Nitric oxide is needed to keep blood vessels flexible, so blood can move through them more easily, which also reduces how hard the heart has to work to pump blood.

Thanks Andy for the helpful reply.

So may I try it for my 4 yrs old child.
You know she have earlier seizure disorder (last 3 yrs fully seizure free),ADHD/Moderate ASD and Verbal Apraxia.
She is very much active,intelligent,good skill of receptive language but still not improve her speech.

Please advice and if you think she can take then recommend the dose..

Thank You

She can use a child's dose of L-carnitine. Hopefully, as she grows older, speech therapy will be of more value for her. Make sure you talk to her a lot and show her the names of things.

Thank you Andy.

Please recommend a good brand for L-carnitine and dose also.

Dear Andy,

Please suggest a vitamin name which contains magnesium,calcium,B6 and Zinc.
I am searching this type of vitamin for my daughter hyperactivity.

If you have idea please advice.    

It's very difficult for me to recommend brands of supplements for those outside the US, as I do not know what is available in your areas. It is better to provide links for the products to ask my opinion about them.

Hello Andy,

You can suggest me any brand or name of USA. I will purchase from online as wheatgrass from Puritan as you earlier advised.

Thank you.

There are many brands that are equal. If you can show me a link to a product, I can advise if it's suitable.
