Customer Reviews

Works well
If you are not absorbing methionine very well from your diet, this may be a good option. The effects can be felt immediately, but be careful about your protein and amino acid intakes, to try to avoid kidney complications.*

Order came super fast. I ordered the 500 g package and was well sealed in a white, non-transparent bag. Have been taking 1/4 tsp for about 2 weeks. Cannot tell if it makes a difference yet. Smell is rather strong and taste is strong. Started adding some neutralizing flavor as powder Gatorade to make it more palatable. Otherwise fast delivery and excellent packaging as expected from*

Order arrived in short amount of time, few days. Smaller package than expected which helps when trying to stick your hand way down in a bag of powder. Taste wasnt as bad as the strong vegetable smell. Overall, good product. *

I like the L-Methionine from bulksupplements
Though I have swapped to another brand (NutraBio) - which seems to be just a little better - I have used the L-Methionine from bulksupplements for some time and it seemed to be quite a good quality powder. *

Smell and taste are very mild. It is nothing like Cysteine with it's strong sulfur qualities. Also, the Methionine is much easier on tooth enamel because it isn't complexed with HCL like the Cysteine is.*

Mixes easy. I use it along with Choline and Insoitol. After taking 3000mg C/I and 1500mg M per day for a week or two, my skin is noticeably smoother. I know it's purportedly good for hair as well, but that's hard to judge. *

Histamine blocker
I have only had 2 doses of methionine mixed with Inositol and Choline - the oral version of MIC. The smell and taste wasn't as bad as I expected. I mixed all the powders with a small amount of agave syrup (from Costco) and held the mixture under my tongue for about a minute before swallowing it. Mixing with agave syrup seemed to cut down on the taste. Honey does not work as well.

I bought it mainly for the claims I read here of decreasing gut histamine. I thought I had developed a gluten intolerance in the last few years as I would get a runny nose, mucous in my throat, sniffling, coughing, and even extreme sleepiness almost immediately after eating gluten products. I would even get a "gluten hangover" where I had a headache and fuzziness on awakening in the morning after eating gluten products before bedtime.

WELL I can say that after the first dose - on an empty stomach 1/2 hour before eating - I only got a little bit of mucous in my throat after eating corn bread.
After the second dose I hardly knew I ate 2 biscuits packed with gluten.

I researched and I found out that what I thought was a gluten insensitivity may be an overproduction of histamine in my gut. Some mornings with my protein shake (no gluten) I would still get a runny nose. I was puzzled, until now. Soy (non GMO/Organic) was the base of most of my shakes and Soy has histamines.

With the oral MIC with methionine I feel lighter, have more energy, and less brain fog (gluten/histamine fog). My gut jiggle is gone - even after eating biscuits and cornbread.

I woke up with a headache the morning after taking the recommended amounts so I cut the doses down by 1/3 each.

The first day after taking the MIC (with methionine), I had diarrhea 3 times. Now with the reduced dose - I am good. I will continue using this product and will tell my naturopath about it on my next visit.

BTW - wine, champagne and beer, all naturally contain histamines. I wonder now if our intolerance to alcohol as we grow older is due to increased histamines - and not just age. Maybe after a month of this I will feel brave enough to drink wine. I have avoided wine for the past 2 years as I would get a headache after 2 sips. Maybe methionine will help me not have to buy the Tito's (gluten-free) Vodka I drink due to my "gluten insensitivity" which may turn out to not be about gluten at all.

I appreciate all the comments that mentioned methionine's effect on histamine!*

L-Methionine Powder
I am using this product to assist with hair growth and it has been working.*

Love all their bulk produces
I cant attest to the taste as I am using it for my cats and horses, but I have found all the products are well packaged, and appear to be pure and of high quality. I am very glad that there is a company like Bulk Supplements out there where we can get quality bulk products. I have ordered quite a few different products from this store, and all of them seem to be high quality, pure and the packaging is very good as well.! THANKS!!*

Seems to help with growing my hair
I bought this because my hair stopped growing. I take it along with several other supplements,, such as horsetail, MSM, Cysteine, Proline, so I cant say for sure it is this that is working but my hair definitely grows faster on this regimen. East to ingest and no adverse affects.*

Not so good taste. Just started it today. Seems to energize me*

This is a great product, pure, with no additives. A great product, for a better price, you will be hard pressed to find pure melatonin anywhere else for any cheaper. The only thing one would need is to buy a digital scale that weighs milligrams (on for under $30.00) to weigh out the dosage, an average dose is 3 milligrams. So this product will last a long time, and way cheaper then buying melatonin at some health food store or pharmacy, where you end up paying $10.00 + for 90 pills at 3 milligrams per tablet, plus a bunch of additives. . *

Better than St Johns Wort
I'm on antidepressants, but they're usually not enough. L-Methionine helps give me a good emotional boost. Not sure if that's the way it's intended, but that's how it works for me.*

L-Methionine and PEA together in the morning give me the energy to get out the door and get to the gym and work. Bulk supplements web site was easy to navigate and there service was extremely fast. I received my package in 2 days.
Thanks you*

fast shipping
I was a little impressed as to how fast I received my supplement, since shipments usually take longer living in hawaii. The products seems to be good, and it easily dissolves in water. I found dissolving with ester-c or juice is the best way to cover up the unpleasant taste. *

On 6/7/2014 tracy said...

When I opened it, it smelled bad lol, but once I mixed it in a protein shake I couldn't even taste it. Will definitely reorder : )*

On 5/23/2014 Shelby said...

I am so impressed with the apparent quality of the supplements I have obtained from Bulk Supplements. They all mix well and are not unpleasant to take. It will take time to see their effects since I am relatively new to supplementation,
I do want to say that the Customer Service is wonderful and the speed at which it comes is amazing. It is packaged so well also and seems so fresh.*

I have tried other methionine products and I can say that I am happy with my recent order of l- methionine from bulk supplements. One thing I noticed right away was the freshness of the product. The smell was much stronger than other products I have tried. I can really feel a difference taking this product. I feel I have more energy. I believe this product to be pure and not cut with fillers. I plan to order all my methionine from bulk supplements for now on. In my opinion it is a much better supplement than I have been using.*
