Glycine
Excellent quality product. Pleasant taste, sweet and pleasant to take. Contributes to quality sleep as it has a relaxing effect. This is the second time I've bought this product. I'm totally satisfied.

L-TYROSINE POWDER
Just what I was looking for
Adequate format to be able to select the dose. I include it in the pre-workout for the last phases of the definition where you are running low on motivation and energy.

VERIFIED OPINION
L-TYROSINE POWDER
Quality in training
I have seen comments that it is not noticeable at all, of course, like other things... but when a sports nutrition expert introduces it in his pre-workout shakes as essential, it will be for a reason.

L-TYROSINE POWDER
Excipient-free and highly effective
I usually buy powdered supplements from HSN for their quality and good price. This one in particular I take for thyroid and it has a remarkable effect, reducing in several points the tsh.

L-TYROSINE POWDER
Good product
When it comes to studying it is a basic to increase that focus and concentration that I have been lacking lately. Not that it is magic, but something is noticeable.

L-TYROSINE POWDER
Easy and comfortable to take
It was prescribed to me by my Internal Medicine doctor to reinforce the Eutirox treatment for hypothyroidism. It has hardly any taste, is pleasant and easy to take. You have to dose it well, of course.

The presentation is not the best but it is perfect for when you have PCOS. I would buy it again.
