B-203 – Carnitine


Acetyl-L-Carnitine (ALCAR) is L-carnitine bound to an acetyl group. This form of carnitine is known as the neurological variant of L-carnitine because it can pass through the blood-brain barrier. As a result, it has more interactions with the central nervous system. These unique properties cannot be attributed to other forms of carnitine.

L-Carnitine Fumarate is bound to fumaric acid. L-Fumarate is a substance that occurs naturally in the body as a citric acid cycle intermediate; in this cycle energy (ATP) is produced. Just as vitamin D3, fumaric acid is produced in the skin when exposed to direct sunlight. Fumaric acid coupled to the L-carnitine part creates a synergistic whole. This form is widely used as an energy booster and to assist with weight loss.

L-Carnitine L-tartrate (LCLT) is L-carnitine bound to tartaric acid, and is absorbed faster than other L-carnitine variants. The rapid influx makes this form particularly suitable for time-critical situations, such as immediately before or after sporting activities and as such the supplement is mainly used by athletes. Also, L-carnitine L-tartrate interacts with hormones such as testosterone, moderating the availability of androgen receptors.

    When it comes to the world of supplementation, it seems advanced forms of carnitine are completely overlooked.

    TNT have addressed this by utilizing 3 forms of Carnitine and at a full serving size it’s adequately dosed – usually this is the part where companies bypass dosing just to claim they have something worthy, Not TNT.

    From the very onset of utilizing this prior to my workout I’ve noticed only good, scratch that – great, results.

    Athletic performance has been the main standout factor for me as well as general recovery by being less sore but training longer and more importantly harder.

    Cognitive function and mood felt great, which makes it a no brainer to be used as part of my pre workout regimen especially since it leads to more productive workouts.

    Although my calories have increased by a good 500 or so calories my weight has remained the same but visibility my condition and muscle tightness has improved.

    This is a very versatile and ultra effective product, way more than just your usual l carnitine. This definitely is going to be apart of my stack, on a bulk or cut. Absolutely love this stuff and I highly recommend it as you can see.
