Protein  supplementation :

Since proteins aids in weight loss protein supplementation , keto diet is trend these days.They say whey protein is water soluble and is safe but some may contain high added sugars which is not advisable. Some studies conducted on protein powders said it contained heavy metals such as lead, arsenic, cadmium, and mercury , BPA (bis-phenol) , pesticides linked to cancer.
But not all the protein powders contained these harmful substances.

So what you should do :
  • Try getting protein from diet rather than supplementation.
  • Take chemical free protein powder under medical supervision.
  • I also heard children in sports too are advised by coaches on protein supplements. Go to doctor and give it only under medical supervision.

Conclusion:

These days I am hearing alot about protein supplementation. 
I asked my friend what is for breakfast and she said protein powder in a glass of milk. I even saw my friend who eats chicken , eggs, sprouted grams, milk in a day to move the weight scale down. And heard protein supplement for teenager who is into competitive sports . So I thought of putting down this into blog about protein requirements and supplementation. Hope this helps. Again , I wish to end this article saying protein is vital for our body with various functions but before supplementation take under medical supervision. 

Thank you for reading,

Divya Lokesh.
