L-Tyrosine is an amino acid which supports brain function. It can be converted by neurons in the brain into the neurotransmitters dopamine and norepinephrine (noradrenaline), hormones which are depleted by stress, excessive work and certain drugs. By replenishing norepinephrine in the brain, mental energy levels are enhanced and a feeling of contentment often occurs.

L-Tyrosine boosts certain neurotransmitters in the brain and has been used to support stress reduction and depression. L-Tyrosine is converted in the body into other key biologic compounds, including CoQ10, thyroid hormones and melanin.

Tyrosine can also enhance athletic performance. L-Tyrosine is an important component of protein and helps form the bioactive factors vital to cellular growth and maintenance. Tyrosine supplementation has the potential to increase athletic performance in a few ways. One of the mechanisms possibly contributing to fatigue during exercise is an increase in central serotonin levels and an increase in the ratio of serotonin to dopamine. Tyrosine may help decrease this ratio and compete with tryptophan (the amino acid precursor to serotonin) at the blood-brain barrier. Increased dopaminergic activity may decrease the perception of fatigue. Also, during highly stressful conditions, catecholamine levels can become depleted, and tyrosine may be particularly useful under these conditions.

NutraBio.com L-Tyrosine is pure free form crystalline amino acid from microbiological fermentation. It is NOT derived from milk. The B vitamins pyridoxine (B-6) and folic acid can assist in the conversion process.

Extremely durable, highly recommended!!
Color: Orange
This ball was a game changer for us!! I rehomed an extremely needy 110 pound one and a half year-old male Rott. This ball has been keeping him engaged for hours giving a much-needed break to me.😜 it actually stays charged a lot longer than I thought it would, and so far he is not chewed through it at all, which is incredible to me!! I think I’m gonna order another one so that I can have one charging while he plays with one and then switch off with them.

A hit for Border Collies
Color: Blue
Our border collie loves this toy! Keeps him entertained and when he throws it down it doesn't break open. Going strong for a couple days so far.

Best toy every
Color: Orange, Color: Orange
My husky loves it. It's one toy she's not been able to destroy yet. She plays without when she's outside in her lot and will play for an hr at a time. She loves it moves and bounces instead of just tossing it and letting her fetch. The battery life is really good. We charge it about twice a week. It's quiet, so she loves that. It's perfect size for her.

They love it! Good quality toy.
Color: Orange
My dogs love this ball. The texture is perfect. They like being able to bite it. It doesn’t tear apart when they do either. Other interactive balls I’ve purchased have been hard plastic and much louder. Everyone is enjoying this toy more than those. It’s so fun to watch the dogs play with this. Video is from the first moment it arrived. They both play with it hard now. We’ve had it three days. I’ll update its longevity if it’s shorter than I feel it should be.
