Customer Reviews

Great Product
this is my favorite form of carnitine for cognition and fat burn/endurance. the bulk supplements products are always pure and priced most competitively. i can definitely tell this is a high quality product after 3 days. It works better than expected.*

On 9/5/2017 Daniel said...

High Quality
This is one of the best supplements that I have had and it's very good. I wish I had this product earlier.*

On 7/10/2017 Wade said...

High quality, best prices, bulk supplements are the best *

On 5/22/2017 Russell said...

Zinga Zing Zing
This is excellent quality ALCAR. At three to four grams a day it keeps my mind pinging right along with superior memory, mood, and dare I say, intellect.

Bulk Supps is the best place to get it to boot.*

On 3/14/2017 Troy said...

Good Stuff
Seems to help noticeably with energy and focus. Would recommend.*

On 3/5/2017 Sam said...

ALCAR Vegi Caps 600mg
Excellent product, easy ti swallow and fast shipping.*

On 8/2/2016 ken said...

Pure Stuff!
I was very excited to find this product as it is pure ALCAR in capsule form. With just about every other brand you will find they will include additives like rice flour, titanium dioxide, and magnesium stearate. The quality is also very good, I have been taking ALCAR on and off for about 3 years and this is the best one I have found so far!*

On 7/24/2016 Dalton said...

ALCAR for a zippy brain
I love this stuff! Life is better with 3-4 grams ALCAR every day. This is the best place to buy it, too. Cost is low due to no advertising and the product is pure and potent. Bulk Supps is the best.*

On 6/5/2016 Troy said...

ALCAR = all right
I'm only a bit over a week into my supply, but 2x/day (morning and mid-afternoon) usage of ALCAR seems to provide more clarity and leaves me feeling more cognisant overall versus a comparable product from Onnit.*

On 5/12/2016 Jeremy said...

ALCAR Capsules are great!
This is a great energy increasing and fat burning supplement. I highly recommend!*

On 5/1/2016 Connor said...

neither here nor there
I noticed nothing from taking these. Reading others reviews I hoped they might help me feel more clear headed, or more energy. Maybe I just don't need L-carnitine. I do love this company and repeat buy other products.*

On 2/14/2016 mindy said...

so far so good
Ive only been taking this supplement for a week, but I can already tell that I am more clear headed. I will definitely continue to take them.*

On 11/10/2015 alejandro said...

Acetyl L-Carnitine (ALCAR) Capsules - 100 Gelatin Capsules
This product seems to be more potent than expected and is packaged perfectly as no moisture ever made the product sticky which seems to happen with this product. The price is right and shipped to my door fast!*

On 9/18/2015 Eric said...

Shipping was extremely fast and packaged nicely as well. I use it to put in my own fat burner recipe as a main ingredient. It's scientifically proven to aid in fat burning.*

On 8/30/2015 Eric M said...

Keeps you going
In this review about Acetyl L-Carnitine or ALCAR, in comparison with other supplements that I've tried, ALCAR works the best. In the first couple of weeks taking two to three capsules throughout the day before that morning workout. Just within the first couple of weeks I've notice that half of day and sometimes a whole day went by without food.

Great product Great results now second order.*

On 6/22/2015 alex said...

I ordered the product, and get it in fast. I am trying it out, and will see how it goes. I'm glad for finding this site, and the great deals they offer. I am sure I will be ordering more from here.*

On 6/4/2015 Keith said...

quality product at a very good price
Up til now I was buying from other sources with a lower quality and higher prices.I am lucky to find this site.*

On 5/6/2015 alakesh mitra said...

Acetyl L-Carnitine
I've been taking this supplement for the past 3 weeks and am impressed with the energy boost. I've been eating more, working out the same amount and losing weight. The only side effect I've noticed is it keeps you up if you take it late at night. I've noticed a difference in the intensity of my workouts, seem to be getting better the past few weeks. Inexpensive and effective.*

Pure, Clean Acetyl-L-Carnitine dissolves instantly in a glass of water
Update 6/12/14: L-Carnitine is for the heart. Acetyl-L-Carnitine is for the brain. The acetyl group makes acetyl-l-carnitine much more water soluble and much more able to pass through the blood brain barrier. The main function of both carnitines is to transport long-chain fatty acids into the mitochondria and metabolize them for energy production.

There are four so-called "mitochondrial targeting nutrients" necessary to crank up mitochondrial health and performance. These are:
1. Acetyl-L-Carnitine,
2. Biotin,
3. alpha lipoic acid in a 100:1 ratio to biotin (50:1 if using R-fraction ALA),
4. Niacin (plus all the other B-vitamins, especially vitamin B-5).

I have been running HIIT (High Intensity Interval Training) sprints for almost the last two years. I was running at the maximum recommended intensity of eight all-out sprints for 30 seconds three times a week.

About six months ago I received the first of the BulkSupplements materials including both l-carnitine and acetyl-l-carnitine. Soon I was running 50-second sprints, eight of them, seven days a week.

But a got sick three times early this year with bad colds, each one lasting over two weeks. I figured it was because I was exercising too hard, suppressing my immune system for too long. All that open-mouthed gasping can lead to a dry throat - and infection. So, I reduced to only five 50-second sprints seven days a week, breathing through my nose the entire time. What an improvement - no more colds. Then, timing myself with a watch, I was able to reduce the elapsed time in these sprints from 54 to 43 seconds (keeping the distance run the same). I can do this with or without caffeine. Whatever pains I had in my chest, or in my legs, no longer appear.

2. Occasional nootropic pre-workout stack: 0.20 tablespoon (0.59 teaspoon) mixed in with the morning stack.
