This supplement is considered pharmaceutical grade and has no fillers of any kind.


As long as suggested serving size is adhered to, risk of negative side effects is low. However, taking too much may result in feelings of constipation. Taking Zinc can help with these feelings, however. Those who have been diagnosed with liver or kidney problems in the past, women who are pregnant or nursing and people who have been diagnosed with schizophrenia or bipolar disorder are cautioned from taking this product.


This supplement is soluble in water of a higher temperature. It has a somewhat bitter taste and may be blended into water, juice or a protein shake. It should be stored in an area that is free from light, heat and moisture.

Because taking more than the average amount of Histidine may sometimes result in a deflation in the amount of Zinc in the body, it is suggested that a Zinc supplement be taken in tandem with any Histidine supplement.

If wanting to increase the effectiveness of this supplement and your workout routine, it is suggested that it be taken with Beta Alanine. This way, the amount of Carnosine in the body will also be increased. This will allow antioxidants to reduce fatigue and slow muscle breakdown.

Customer Reviews

Improves breathing
I love histidine for heavy metal and copper detoxifying and for putting iron where it belongs-into the red blood cells. I used to have trouble just getting a deep breath, and, so far, histidine, about 3 grams a day (taken 2x/day) has really helped with my breathing! *

Amen-Ra Protocol
I have recently started to slowly implement the Amen-Ra protocol, which basically includes a 23 hour fast, with a 1 hour eating window. To break the fast, the regimen has a detailed Amino Elixir containing 12 amino acids among many other ingredients, maximizing life span and inducing autophagy. Search for Dr. Nun Amen-Ra to find his official website!! This website is amazing to use for sourcing the pure Amino Acids I use for my elixir. The Histidine HCL is very helpful as the hydrochloric acid helps the stomach break down and digest the many nutrients in the elixir and the one meal afterwards. Highly recommended. *

This is THE number ONE antihistamine and this granular one works right away. This is the best. It works right away, good for any itches, hives, etc.
For awhile histidine was taken off the market. I'm so happy to see back !
I was so happy to find this in powder (granular form). It takes a minute or two to dissolve and the taste in just a small amount of water is hardly there.
500mg is plenty - long lasting.*

Not only have I been ordering many supplements from here I'm very impressed with quality, distribution, and everything about bulk supplements. I'm leaving a review on histidine because of its many benefits. My favorites are for rheumatoid arthritis, and kidney support. Thanks again I really appreciate everything you guys do!*
