L-Carnitine is working on our dog

Posted by iHerb Customer on March 27 2009 | Verified Purchase

As far as I know, your product is working very well, but it's quite expensive. Our veterinarian recommended it for our dog, who has heart problems. He's been on it for over a year now and his arithmia has improved dramatically.

Thanks for your feedback!

The only complaint I have about these is the size of the tablet. The energy boost I get from taking these tablets is wonderful.

dangerous LOT# 3026239 0049

Posted by iHerb Customer on February 23 2018 | Verified Purchase

I take L-carnitine for many years. Including NOW brand that used to be just fine. However one package of NOW L-Carnitine 1000 mg in tablets I bought recently (LOT# 3026239 0049) is plain dangerous. After just 5 min I felt acute gastric ulcer sympthoms. It took me 2 weeks of healing to recover. First time I was not able to attribute my health problem to the package because I take several supplements simultaneously. So after full recovery I took just one tablet of the L-Carnitine with ample amount of food and water. The adverse effect was again almost immidiate and acute. So here we go again I am trying to recover for 10 days by now. I reported the problem to iherb suggesting to recall the product. They responded with bla-bla. I reported the issue to NOW with no response so far. Be carefull! Avoid!

Thanks for your feedback!

Adds Life

Posted by iHerb Customer on February 1 2009 | Verified Purchase

Lab tests from doctor show my L-Carnitine levels back to normal with one 1000mg tablet and a tablespoon of the liquid L-Carnitine each day. More energy and more life!

Thanks for your feedback!

The tablets need to be smaller. They are too big to swallow whole. The product is effective.

Thanks for your feedback!

Caplets not capsules

Posted by iHerb Customer on February 19 2009 | Verified Purchase

People should know these 1000 mg. pills are caplets, not capsules. I have gone back to the 500mg. capsules myself. You may need 2(or 4) capsules, but they seem to work better,for me.

Thanks for your feedback!
