Review: If you need help, these products.....WORK! - First of all, let's take a moment and wait for all the amazing, well meaning hippies and planet earth enthusiasts to leave this review section. Go on, I'll wait tilI I hear your birkenstocks clop clop clop down the hallway before I begin. Heaven forbid anyone of them buy a product that isn't made from 100% organic and blessed by New Zealand made vegetarian duck farts. Yes this product comes from China, so by default everything is evil and cruel in the world and toxic and we're going to give ourselves cancer because it's not double certified and and kosher blessed by a rabbi's fart to boot. Wanting to use this product wouldn't have ANYTHING to do with the logic in seeing 10K plus positive reviews stating how these products have helped people (rolls eyes). Now that it's just you and I, I'll continue. I'm here because I was searching for amino acids to buy in bulk without fillers. I wanted something priced fair and pure. After all my searching, Bulk Supplements had the ideal products. The only thing that was left for me to do was scan through all the reviews to see if such products would help me. I have a connective tissue disorder so I made it a point to buy all the aminos that had an effect in regards to tissues of the body. I also bought Glutamine as I read that helped people with their SEVERE bread/wheat/carbohydrate cravings as I have severe bread cravings for that and dairy. I work out often and can never lost the extra 25 pounds because of my food addiction to wheat and dairy. After one day I felt a difference so noticeable I logged in and bought the other remaining 4 amino Acids I needed but did not buy before do to not wanting to spend so much. But since they work and it seems most of these will last 6 months to a year, I opened the floodgates and bought everyone that was unique to me. I ended up buying about 8 products on my first purchase 6 weeks ago. Coming from someone who has tried adding coconut oil, vitamins, probiotics, nothing ever seemed to make much of a difference. It wasn't until I started taking amino acids that everything moved forward for me in my health goals. THIS......STUFF.......WORKS! I also have chronic fatigue syndrome and I'm seeing progress in my energy and health. I want to add that I also bought the Potassium citrate. I can't EMPHASIZE ENOUGH HOW MUCH THAT ALSO HELPED ME! I work out every other day and I use the sauna for about 40 minutes. In conjunction with taking aminos and now getting about 5K (4700 the average, but I workout hard) mg of potassium citrate, I'm feeling so much better! Even in my workouts I had to increase the weight by about 20 percent on the machines I use, and I even had to add more reps onto my sets! My original workout felt like I never even worked out since taking these products! Now even with added weight and reps onto my workout regimen, I still feel like I didn't quite workout enough! But I keep my increases minimal as I don't want to go ahead to much. But I can't flipping believe how much these products have boosted what I can do in the weight room AND not feel like a gassed race horse when I'm done. This stuff is literally the MAGIC powder. And with how its helping me with regular health outside of working out and also keeping me from falling off on binge eating on pizza and ice cream, this stuff is it. I'll always be a consumer of these products. Since I already ordered 3 times from this company (LOL) in the last 6 weeks, I got three free sample products to try that I WOULD NOT NORMALLY BUY! But since they also helped, I ended up adding them onto my next order! And to those people that complained about getting the free samples being just a marketing ploy and other nonsense, BUGGER OFF! There are products I wouldn't have bothered to try but since I got to try them for free and I liked them, I added them onto my next purchase. Because they worked for ME. You're getting a product that could very well last for a month and free shipping, all you have to do is leave a review if you like it or not. Yes, what a scam bulk supplements is running (rolls eyes). As of now there are two other products I plan on ordering from them, the Melatonin and the BCAA 3-1-2 product. Again, I'm only doing this because of how much positive gains I'm seeing in my health and workout. Another bonus was I could never eat enough meat, I was always hungry for tuna, turkey, beef, I could never get enough and my grocery bill was always high. Now I can eat a normal serving of meat and I feel like I don't need anymore thanks to taking the Acetylcarnitine and the Creatine, components that are found in muscle tissue. How I take my supplements is as follows- I take one serving size amount of each one in the morning. Then in the evening I take one serving size of only the msm, ascorbic acid, acetyl carnitine, Arginine, L-Glutamine, D-Ribose, potassium citrate. I take this because of budget, I want what I have to last longer, but these products are most important in keeping my cravings at bay so I take them once more at night. You can take some of these 3 times a day it says, but I only do them all once, and what I just listed twice. If I was rich and could afford $300 in supplements every 2-3 months I'd take them 3 times day. But since I'm not I make them last :) In summary, what I take is what I feel my body needs. And I am 100% happy with the effects I have experienced. And as for odors like some people described when they open their packages, well.........Some of these are chemicals, aren't they? MSM will smell like a sulphur like smell, correct? Unless you want added scents to mask things (which I don't) I honestly have not had a problem with that. And for the foil cosing bag, what I did was go to Walmart and buy a package of the large sized mason jars and I use those to hold my amino's in. I can't see knocking off a star because of the foil bag seal. Just pour it in a wide mouth mason jar and get a measure spoon to dish it out. If you're wondering what products I've used with this company, if you're reading this review then this is the product I purchased and have in my pantry. I'm not rewriting a review for each item, so I am copying and pasting a review to use on every item I bought from them. Any other questions please ask, but I find that as a person with health issues and food issues these items have helped me beyond anything else I've ever tried. Why no voting buttons? We don't let customers vote on their own reviews, so the voting buttons appear only when you look at reviews submitted by others. Permalink
Review: Taking L-Proline to Help with the Healing of My Bone Fracture - Very recently I suffered a bone fracture, and also learned that I have osteoporosis. I asked my doctors what supplements I could take along with their prescriptions for me. They suggested ordinary things (multiple vitamin, calcium. Vitamin D) which I am already taking daily. Hearing this less-than-inspiring recommendation, I decided to search the medical literature to see what else might be out there. Several university or medical research studies exist which show the positive benefits of L-Proline in the healing of bone fractures. For this reason I decided to order it and begin using it on a daily basis. I have frequently purchased a variety of Bulk Supplements brand amino acids in powder form. The quality of Bulk Supplements ranks very high with me, which is why I always come back to them when I need an amino acid, such as in my case of bone fracture. Their packaging is also very durable and reusable for opening and closing. These factors are important to me, since the 500 gram package will last me some months and remain in good shape as I open and close it. I don't have to worry about repackaging it because the package does not hold up. I always recommend amino acid powders in Bulk Supplements format to my friends for a number of reasons: (1) You know exactly what you are getting with no hidden fillers; if you ever have a question about any aspect of the products, the Bulk Supplements people will give you detailed and reliable answers to you question. (2) Bulk Supplements are a better buy over capsules or tablets; the processing costs of making tablets or capsules are high and you pay for that. (3) Powders give you the freedom of mixing them in your favorite beverage and you can very easily control the dose you want to take. As you can tell, I am very satisfied with amino acid powders and the consistent quality in over 8 of the Bulk Supplements product line that I have purchased over time. i generally look for the powder form of a nutritional supplement first before considering capsules or tablets. I have avoided taking unnecessary fillers and binders for hundreds of doses of products over the years. Those gelatin capsules really add up over time. I am very certain that my fracture will heal better and sooner, as the research reports I have read will suggest.

### ⭐⭐⭐⭐⭐ One of many Bulk Supplements item I will not be without.
*by B***E on March 24, 2017*

I take a mix of Ascorbic Acid (vitamin C), L-Proline, L-Citrulline, AAKG, L-Lysine HCL, Pine Bark Extract, and Coenzyme Q10 daily. I add 16 oz of water, a splash of Black and Blueberry Sobe water for flavor and shake. Since there is ascorbic acid in this mix I use a straw so that my enamel is not damaged. The recipe is something my husband found online and recommended we start taking as we both had been catching winter viruses brought home from my husband's job at a hospital or our local gym. I also wanted help recovering from our workouts, as I was post-op, out of shape, and sore. If I miss a day, my body literally tells me I need this. I feel so much better now, and an added benefit is I find myself eating less because I am not hungry. The company is excellent and the powders are pure, with no extra additives. I did receive a small sample of COQ10 for free after ordering all the other items. When asked to review the previously purchased items, I informed them I would, but only after a month of continuous use. I also like that the company will send you coupons for future purchases of their items, because I am cheap/frugal and like saving money.
