I am concerned recently about taking tyrosine, I have read about it increasing the melanin levels in the skin causing you to tan, now I am pretty fair skinned and have quite a few moles on my body, of which I have had some removed recently, should I drop the tyrosine or is it completely safe to take regarding skin safety i.e. could it promote the deveopment of a melanoma?

I love taking tyrosine, it is probably my favourite supplement in terms on energy levels and alertness for studying, increasing dopamine and norepinephrine, so would like to know if it is safe to take regarding the skin and if not is there an alternative for dopamine without increasing melanin in the skin?

Or am I just being paranoid!

Ive been using tyrosine for almost one year. I've noticed that the tanning effect is only enhanced, by a bit, when you get sun exposure. Other than this, I haven't noticed a serious tanning effect at a dose of 500 mg - 5 grams.

Tanning != cancer. Sun exposure = cancer.

I am a biochemistry major and I took an introductory Biochem course last summer and I asked this very question my prof because I was an avid tanner and quite a few of my tanning lotions had tyrosine in it. He told me that regardless of how you are getting the tyrosine (oral or topical) your body will use it for what its needed for and taking an over abundance of it will not make you tan more or increase production of melanin. So ingesting tyrosine will not cause melanoma. It is just the building block of melanin and you still need UV exposure to tan. It is the UV exposure that causes melanoma.

Thanks, that's put me more at rest, I don't really tend to do any tanning really so should be ok, due to living in the uk I don't get much of a choice, I will continue to take the tyrosine and keep and eye on the moles to see if they change again.

So considering that p53 (upregulated by resveratrol) is involved in tanning and tyrosine is involved in melanin production... will the two combined increase tanning even more? I took a good dosage of both and got commentary on how much I'd tanned. I'd think that a tanning pill would be big business to some people.

Yes, tyrosine is likely a melanoma promoter not an inducer per se (see this thread for an explanation of what this may imply). Tyrosine restriction inhibits growth of melanoma. If you must expose yourself to carcinogenic radiation (teh sun) or are at risk of melanoma, I would rather not add tyrosine.

I think wiserd meant that tyrosine was involved in the production of melanin, not melanoma. If melanin, then it should be safer than tanning without tyrosine. If it is a melanoma promoter, then it's obviously a bad plan.

Sorry to be commenting on old threads but I have been taking l-tyrosine for just 5 days now and I am tanning like crazy, I seem much more susceptible to sun burning, really I have hardily left the house wearing a singlet (maybe 15min in sun)but I have a distinct singlet suntan. I use retin-a on my face, my face is going a nice brown colour but could this be a bad thing? Am I increasing the damage that the sun can do to my skin? I always always wear 15+ Olay day cream and 50+ some korean brand sun screen on my face in the day even if im staying indoors but yeah im going brown. I think the UV bouncing inside from open windows is giving me this tan!

I have noticed that my birthmarks have been getting bigger/mole-ier, dunno if its because of tyrosine or not.

More than likely is, unless you're out in the sun more often since you started taking it. I don't think melanocyte stimulation always means different abnormalities/additions of/to moles, but you might look into it. Some people also use iodine/apple cider vinegar for their moles to lessen/fade them to the point where they're non-existent.

How much are you taking of tyrosine and @ what time/intervals of the day?

As far as using Retin-A in a daily regimen while @ the same time being exposed to the sun.
I don't know if using a high SPF(15+/+50?) would mitigate the affects of Retin-A + the sun, but I would look into it.

That brown color you're getting on your face is mainly due to the increased sensitivity you're getting from Retin-A.
Are you "tanning like crazy" on all exposed skin or just the face?

I would highly advise against using Retin-A out in the sun for anyone. As far as Retin-A + SPF goes, I have no clue how effective SPF is for sensitive skin(resulting from Retin-A use).

I have been taking a teaspoon of purebulk l-tyrosine in the mornings. It really seems to get me going! yesterday I had not slept for 30hrs and I took 3 doses in this period, it woke me straight up each time.

I dont use retin-a very reguarly, maybe it averages out to twice a week. Im tanning all over my body, anywhere that has been exposed to UV and I dont mean sunlight, just indoors or walking to the shop for 5min etc.. I have not spent anytime out in the sun.

Im always careful to keep my face out of the sun.

Have used retin-a for a year now.

for the people who take tyrosine, why not try n-acetyl-tyrosine ? its smaller doses, more bioavailable and it crosses BBB. yet, most of you take grams of the stuff thats not required.

Is NALT also harmful to the skin?

[UnknownSuitor]

Renfr, Don't listen to MrClock. NALT is not more bioavailable then Tyrosine. As far as I know there is no superior usage of NALT over Tyrosine.

Read the other thread 'Tyrsoine 1/8 of Limitless NZT' it should be at the top list of threads.
