BULKSUPPLEMENTS.COM L-Proline Powder - Amino Acid Powder for Bone, Joints and Skin - Unflavored, Gluten Free, No Filler Powder - 2000mg per Serving, 500 Servings (1 Kilogram - 2.2 lbs)

The product was fine but it was not put in a protective envelope and the shipping label was put on top of product name and directions; fortunately I know how to look that info up on line

Since I used a shotgun approach to the supplements, this time, I can’t comment on the effectiveness of this particular supplement on its own. My attempt was to use Serovital (spelling?)and some other HGH boosters as a blueprint. The mixture contains L-Glutamine, L-Lysine, n-Acetyl L-Cysteine, L-Ornithine HCL, Glycine, L-Arginine Base, L-Proline and Schisandra, all of them from Bulk Supplements. There may be a synergistic effect to them and as I run out of each I will see if they are all needed or if some can be left out. This supplement tastes like an artificial sweetener (yuck). Mix it into something with a strong flavor. The mixture works very well so far. This has been the best sleep I have had in over 20yrs. I now sleep all night long only, rarely, getting a poor nights sleep. This is usually caused by me doing something stupid like eating too much right before bed. I also have clear dreams that I can remember the next day (unheard of before). My energy is up drastically, probably due to the improved sleep. I feel like exercising and recover from hard workouts much faster than “normal”.

I ordered and have been taking this combo first thing in the morning. You can’t store these amino acids — you need to consume new ones every day for your body to use them to make collagen. So to ensure that your body has enough, you want to take about 3 grams of L-Lysine and 1.5 grams of L-Proline, along with vitamin C every day to build up your collagen levels. Follow this protocol and your arteries will be soft, supple, and calcium-deposit free also. I just started this so it is probably going to take a few months to see results.

I don't often write reviews, but I believe this is serious enough to share with anyone considering a purchase. Over 20 years ago, our doctor told my husband that his LPa value was too high (seems this can be a marker for heart disease). He suggested we begin using the amino acid, Proline. We did and after a few months, my husband's LPa numbers plummeted. We used the same brand for many years and the numbers remained low. In 2015, I decided to try a less expensive Proline option...BulkSupplements. My husband took it for close to a year and when he had his LPa tested, his values had soared to 280. Of course, I wracked my brain as to what we had done differently. I, then, decided to go back to the original brand of Proline that we used for over 20 years and lo and behold his last blood test showed a dramatic reduction of LPa...well under 100. In my mind, there can be no other reason for the steep increase in numbers and the significant decrease when we returned to our original brand. I no longer have any faith in the BulkSupplements Proline Powder...or the BulkSupplements brand. I've always been hesitant about any powder manufactured in China (how do you really know for sure what is in the powders?) Unfortunately, I went with Amazon's good reviews. Perhaps, others have had good luck with this product, but if you are using it to bring down LPa, I would recommend you think twice.

Pay more for capsules or tablets? Nope. Bulk Supplements is just what I needed to find when the company I have buying bulk (powder/loose) supplements from for years curtailed their operations because of increasing government regulation. Unadulterated products at the best price. Hopefully they'll have even more in the future. This proline powdered is just as good as what I've bought in the past and I'll definately be buying more when I run out. Ans I'll be buying other supplements in from them in the meantime.
