Twinlab's Amino Fuel Liquid - Product Review  Hot



Twinlab's Amino Fuel Liquid is a high performance amino supplement that synergistically combines fast absorbing liquid aminos with choline, amino-supporting B complex vitamins, energizing complex carbohydrates (glucose polymers) and pure crystalline fructose (fruit sugar). This high tech formula includes branched chain, peptide-bonded and free amino acids derived from whey protein (lactalbumin), egg protein (albumin) and liver protein. The resulting peptide bonded amino acid liquid concentrate ensures a positive nitrogen balance, where high levels of protein are maintained in the muscle for maximum muscle growth, energy and performance.

Twenty amino acids are needed to produce necessary body proteins and enzymes. They build the proteins used in the growth, repair, and maintenance of body tissues, such as muscle. Amino Fuel Liquid includes a full spectrum of non-essential and essential amino acids to ensure total protein utilization. Essential amino acids can only be derived from protein foods (such as red meat and dairy products) or dietary supplements.

Amino Fuel Liquid also includes L-carnitine, which is produced in the body from the essential amino acids methionine and lysine. L-carnitine enhances cellular energy production by using fat as energy. This increased use of fat as energy can preserve muscle glycogen (stored energy) and decrease muscle fatigue. Some studies show that L-carnitine supplementation can enhance athletic performance, especially intense exercise activities.

Twinlab's formula is further enhanced by energizing complex carbohydrates, amino-supporting B complex vitamins and choline. Choline is a natural compound found in protein and fat-containing foods such as eggs, liver, soybeans and peanuts. Choline supplementation can build levels of the neurotransmitter acetylcholine in the nervous system. Since acetylcholine plays a role in muscle contractions, choline supplementation can help improve athletic performance and shorten recovery times.

Taking a potent liquid amino supplement such as Twinlab's Amino Fuel Liquid can maximize muscle growth, enhance positive nitrogen retention (stored muscle protein) and improve physical performance.


This quick-acting, easily digested liquid provides 15 grams of concentrated amino acids. One serving of Amino Fuel Liquid is equivalent to 15 one-gram peptide bonded amino acid tablets or capsule. Twinlab states that the peptide-bonded amino acids in Amino Fuel Liquid increase nitrogen retention better than free form amino acid mixtures for maximum muscle mass. You'll get more high quality nutrients for your money with Amino Fuel Liquid.

Studies have found that the nutrients in Amino Fuel Liquid have numerous benefits including:

  • Maximizes muscle growth
  • Enhances positive nitrogen retention (stored muscle protein)
  • Improves performance
  • Boosts muscle energ


Few side effects have been reported with the short-term use of amino acids. However, mega-dosing amino acids over an extended period of time may result in potential side effects, such as causing excess nitrogen to be excreted as urea in urine. The excess nitrogen has been linked with reduced kidney function.

Although side effects are uncommon, nausea, vomiting, diarrhea, body odor and stomach upset have been reported with the use of L-carnitine.

People with hypothyroidism, seizures, high triglyceride levels, ALS (amyotrophic lateral sclerosis), depression, Reye's Syndrome, kidney or liver disease should not supplement with amino acids or L-carnitine without consulting a physician.

Be aware that some drugs may interact with the nutrients in Amino Fuel Liquid including:

  • Allopurinol
  • Anticonvulsants
  • AZT
  • Chemotherapy
  • Cisplatin
  • Cyclophosphamide
  • Docetaxel
  • Doxorubicin
  • Fluorouracil
  • Gabapentin
  • Methotrexate
  • Paclitaxel
  • Phenobarbitol
  • Valproic Acid

Is it for you?

If you're a bodybuilder, athlete or fitness buff wanting to maximize muscle growth, boost muscle energy and optimize muscle protein production, Amino Fuel Liquid is for you. Vegans/vegetarians would also benefit from Liquid Amino 2222 supplementation. However, people with hypothyroidism, seizures, high triglyceride levels, ALS (amyotrophic lateral sclerosis), depression, Reye's Syndrome, kidney or liver disease should not supplement with amino acids or L-carnitine without consulting a physician.

Dosage and Directions

Shake well. Take 3 tablespoonfuls daily or as recommended by a professional trainer. Amino Fuel Liquid may be taken with meals, between meals, or as a muscle-building aid before or after training. For best results, use as part of a low fat diet and exercise program.
