Suggested Use
L-tyrosine is a non-essential amino acid important in the production of neurotransmitters such as dopamine, epinephrine, and norepinephrine – required for managing stress. It helps decrease cognitive fatigue due to physically stressful situations and promotes normal and healthy brain function including memory and concentration. It also supports normal muscle movement.
Advanced Info

L-tyrosine is an amino acid required for protein synthesis, and is a precursor for several important compounds, including thyroxin, melanin, and the neurotransmitters dopamine and norepinephrine. Dopamine and norepinephrine are important hormones and central nervous system transmitters that help maintain mood, attention and focus, and cognition. By increasing dopamine and norepinephrine at the cellular level, tyrosine may help maintain neurological health and improve mood, cognition, attention, and memory.

Tyrosine is a potent antioxidant and appears to act as an adaptogen during conditions of physical and mental stress, as shown by its ability to normalize blood pressure, alleviate fatigue, and improve cognitive function, attention, psychomotor skills, and memory. These effects may be due to tyrosine’s ability to affect brain chemicals and promote positive changes in brain pathways.

Tyrosine helps alleviate some of the effects of stress. Studies in humans show supplementation with tyrosine improves various aspects of cognitive function and physical symptoms of fatigue during exposure to physical stressors such as cold, high altitude, and extended wakefulness. Improvements are thought to be due to balancing brain chemicals and improving cognitive function.

Absorbs into the skin well and no irritation so far
I bought this Cyperus Rotundus oil to try out, and the 1.85 oz bottle is a good size for me. The oil has a light botanical scent that is pleasant and not too strong. I have applied it a few times and found that it is very easy to use with the included dropper. It absorbs into the skin well and I have noticed no irritation at all, which is important for my daily routine. The bottle arrived quickly and was packaged securely so there were no leaks. It is a practical addition to my shelf, and the glass container feels solid. This product does exactly what it says on the label and provides a straightforward way to use a natural oil. It is a functional and simple purchase that meets my needs perfectly.

Smooth skin without the post-shave itch
I’ve always had issues with my skin feeling super irritated after I shave my legs, so I started applying this Cyperus Rotundus oil right after hopping out of the shower. The quality of the blend is impressive—it’s got jojoba and almond oil too, so it feels very nourishing rather than just sitting on top of the skin. It absorbs quickly enough that I can put on my leggings and head to the gym without feeling like a greaseball. The functionality as a hair inhibitor is a nice bonus. I’ve noticed the hair on my shins seems to be coming back a bit softer and less stubbly than before. For a 55 ml bottle, the value for money is solid since you only need a few drops to cover a large area. It’s a great find for anyone who deals with that annoying sandpaper feeling a day after waxing. My roommate even started using it on her arms because it’s fragrance-free and doesn't mess with her perfume.

Lightweight oil that fits into a simple routine
I started using this oil as part of my regular skincare routine, mainly applying it to areas like my arms and face after showering. The texture feels light and spreads easily without leaving a heavy residue. I noticed it absorbs fairly quickly, which makes it convenient for daily use. It also has a mild scent that is not overwhelming. I like that it includes plant based ingredients, and it leaves my skin feeling soft after application.

Refreshing orange scent
These are effective at refreshing your disposal. When I am done cleaning up my kitchen I put 2 drops in the disposal side of my sink and briefly pulse the disposal to break open the drop. Don't run any water as this will wash away the drop and the fresh orange scent. I am very sensitive to perfume or floral fragrances - these are just the right amount of orange scent to make your drain smell fresh without the scent overwhelming the kitchen.
