L-HISTIDINE GUARD
PERQUE L-Histidine Guard is an essential amino acid for gut and immune support. L-histidine supplementation can help restore optimum stomach acid production and in turn stimulate the secretion of gastric juices such as pepsin and hydrochloric acid. L-histidine is a good source of stomach acid protons, which are often lacking in people with inherent digestive issues and those with allergies. L-histidine also has significant physiological antioxidant properties.
Health Benefits:
- Supports healthy stomach acid production for optimum digestion.
- Provides safer antioxidant benefit to address oxidative stress.
- Supports healthier cellular metabolism and histidine-histamine balance.
L-histidine is important for both digestive health and immune system function. In addition to stimulating gastric acid and gastric juice production, l-histidine can scavenge free radicals and help remove toxic “divalent” metal ions from the body, providing an anti-inflammatory effect while empowering the body to boost its inherent antioxidant pools.
Histidine is the precursor for other important organic compounds such as anserine and carnosine which also add to the antioxidant capacity of the body, preventing oxidative damage to cells, and supporting skeletal, muscular and cardiac health.
Finally, L-histidine is a precursor for histamine. Histamine has a variety of roles including: functioning as a neurotransmitter, stimulating stomach cells to produce gastric acid, and providing a local immune response to foreign material.
Directions:
- As a dietary supplement, take one (1) capsule 30 minutes before meals or as directed by your healthcare practitioner.

Organic Chamomile with Lavender
I've been using essential oil balms for aches and pains, and they definitely help but their smell is rather strong. Magsoothium cream, by contrast, has a mild, pleasant flowery smell. I use it when I go out and do find it effective for moderate pain. I also use it at bedtime on my calves, as the magnesium helps with leg cramps which often wake me up - and it might be helping me to sleep better as well! I first ordered the small size to test it out, but took advantage of a recent sale and ordered two of the large size.
I appreciate how Village Green supplies the order quickly and efficiently!
High quality goods, well-informed friendly staff, reasonable pricing and regular discounts. Feels old school and good to have a small shop that's so well stocked.
I have been ordering from Village Green Apothecary for years and can’t say enough about the staff’s expertise and all they have available for customers in guidance and support. Thank you from the bottom of my heart to Louis & Tatiana for their guidance, help & support for years. I am forever grateful! I also want to thank Brian, Kirsten, Kayla & the pharmacist for all their help. Another positive about Village Green is their rewards program, supplement sales which are often and especially their phenomenal semi-annual store wide sales. I have recommended Village Green Apothecary to all those I know!
