Hi doctor,

I used to perform cardio exercise for around 30 to 40 minutes and weight exercise (strength training) between 20 to 30 minutes daily. I have been using one natural protein product. My wish is to lose fat. I am confused whether, I should replace my natural protein product with the second one, which I found on the internet. I have a few queries which are as follows. The second protein product has a prefix "L" over all the amino acid ingredients and also contains glutamine in addition to BCAAs. What does it mean? Is glutamine necessary? I take maximum 25 g of supplementation in my dietary intake daily. Is 25 g sufficient or do I need to increase or decrease? Lastly, should I continue with the first protein product or the second one? I am attaching the photos of the protein products here for your reference. Please help.



Welcome to

1. "L" is the structural name; in fact Lysine and L-Lysine are the same. Not only in Lysine, it gives the same meaning in all amino acids mentioned on the product package (attachment removed to protect patient identity). 2. Glutamine is safe and required for body building. You need up to 30-40 g daily as you are interested to start. Only in cases of liver, kidney, mental disorders and pregnancy either it should be avoided completely or not to be taken in high doses. 3. I suggest you to continue any protein supplement up to 40 g in two divided doses with a maximum of 20 g per time. 4. The second one, which you have mentioned, has so many ingredients and it may be helpful for muscles, but may have future complications or health hazards. 5. So, I think the first one is better till you go with normal exercises. In case of rigorous gym, then another one could be helpful (depends on man to man). 6. One can start the supplement at low doses 20 g one time at breakfast and the next same dose at evening or bedtime. In total 40 g maximum as per safety is concerned. If you are interested, then you can start with low doses of the protein product. For further information consult a nutritionist online -->

Thank you doctor,

I just wanted to confirm that in the absence of glutamine, does natural protein have any considerable adverse affect for muscle recovery, in case of moderate weight lifting?



Welcome back to

1. No, not at all. I suggest you can increase 10 g more or 1 scoop more than the present amount you are taking. 2. After two months, you can increase the dose of you protein product, but for your safety concern you should take only 40 g per day. Revert back after 10 days to a nutritionist online -->

Dear doctor,

I further wanted to ask you that I have fatty liver and other liver related problems as are evident from my reports as attached herein. And I have these issues from quite some time i.e. for more than 3 years. Also I have certain issues like semi formed stool and non digestion at times. Should I continue to use protein supplements in such a case? Or should I resort to natural diet only? Or can I use the protein supplement and use along some supplement such as Liv 52 to neutralise the effect? If I discontinue the protein supplement, can I continue to do heavy weight training with natural diet? Would it have any adverse affect in terms of fatigue and recovery? I feel very fatigued after sexual activity including masturbation even for the next of whole day. For this I am already using ayurvedic medicine i.e. ashwagandha. Should I further supplement it with some multivitamin? If so may you suggest one and whether it should be with ginseng or without ginseng as ginseng and ashwagandha might have same effect? Are there any digestive enzymes which I can use serves both the purposes i.e. digestion problems and protein absorption? I am using the following medicines currently, Fluoxetine, Vitamin B and D supplements, Brahmi, and Ashwagandha.



Welcome back to

If you are finding stool problems then stop for a week. Then add LIV -52 as this one is Ayurvedic. It help with you for digestion, hunger, enzymatic all in one action. This is also better for liver and as a whole. Needless to say focus on 244-2800 kcal high protein diet at home foods only and a small percentage can be from supplement. So, a home diet is always best for you. We have discussed this even last time and you will not have any effects even heavy exercises. Add more protein to your daily foods. Masturbations should not be frequent. Take tight deep sleep. Even you feel fatigued or tired after the semen fall, you can compensate by high quality protein. Regarding Ginseng or Aswagandha, we do not have too much studies to prove that these are always very effective. You can take Multivitamins with zinc for 15 to 20 days. Concerned enzymes, you can have Aristozyme/Unienzyme liquid or capsule but I never advice as these are allopathic part of Physician. Hence, take a medical doctor's help wherther you need or not. I advice to avoid unnecessary allopathy medicines. Thank you.
