What is Thr Amino Acid (Threonine)?

Thr amino acid, also known as threonine, is an essential amino acid that is used in the biosynthesis of proteins in the human body. Thr amino acids are abundant in meats, but they aren't as common in fruits and vegetables.

Ordering from Bulk Supplements is so easy with great products!

I love the products I order from Bulk Supplements! I take them myself and also put them in an Equine Supplement that I make and sell on line.

Good Deal L-Threonine

All is well. It arrived in a timely manner with no problems. It mixes well with water, or presumably any other liquid. Good reasonably priced supplements. Is a little more trouble than capsules, but only a little. And considering how much more costly the capsules are, this is a very good alternative. This is my second purchase of Bulk Supplements and so far I am very happy with them.


These are high-quality supplements. I won't go back to capsules. My order arrived timely, and I was pleasantly surprised by the potency. I won't review unless I believe in the product even with incentives. This is a great product at an awesome price. I just bought some new jars for my next larger order.

Taking as part of a protocol for chronic EBV...

Have only been taking for about a week, but 1/2tsp of this a day in conjunction with lysine seems to be reducing the viral activity. Feeling less 'flu-ey'

Good Quality

Very good quality. Bought to couple with calcium to improve absorption rate.


I like how pure it seems (would not know without analysis) Kinda clumpy, but dissolves instantly. Great price and fast ship
