Twinlab Nitric Fuel Review

Nitric oxide performs a number of biological functions in the body. One of its most important functions is to cause blood vessels to widen to allow more blood to flow through them. This is known as vasodilation. Improved blood flow is very beneficial for individuals who work out because it improves stamina during the exercise and it improves the recovery afterward. Twinlab Nitric Fuel is a nitric oxide supplement that you might be considering. This review of  Twinlab Nitric Fuel determines if it is a worthwhile supplement to buy and if it is an effective product.

Nitric oxide is produced by the cells which form the inner layer of blood vessels. In these cells, the nitric oxide is made from an amino acid called arginine. The arginine that is present in this supplement, therefore, helps to improve nitric oxide synthesis by providing the necessary building blocks for the process to occur.

Some of the other ingredients support this action like citrulline which can be converted to arginine when it runs out.

Creatinine is an energy source for muscle cells so it helps muscles restore their depleted nutrients to prepare for the next workout.

This supplement is, unfortunately, lacking some key ingredients though. For example, there are several plant extracts that have been scientifically linked with an increased production of nitric oxide in the blood vessels. Beetroot is an example of one of these plant extracts.


Six tablets of Twinlab Nitric Fuel must be taken daily with 12 to 20 oz of water. This serving should be taken 30 minutes before an intense workout. No more than nine tablets should be taken per day.


Customers can choose between purchasing a bottle of 90 tablets or a bottle of 180 tablets. This works out to 15 or 30 servings respectively. 90 tablets can be purchased online for $23.58 and 180 tablets can be bought for $46.03. There are no discounts available for buying multiple bottles at once.


We could not find any evidence of a guarantee offered by this manufacturer. This is concerning because it brings into question the effectiveness of the product – if the manufacturer is not even entirely confident that they are not willing to give customers their money back, how can customers feel confident?

Twinlab Nitric Fuel Review – Conclusion

Some of the ingredients in the supplement are well considered but this supplement is also missing some crucial ingredients. The dosage instructions are comprehensive and clear.

The price of this supplement is quite reasonable, but if you consider that the manufacturer doesn’t offer a guarantee, the price is a bit of a gamble. It’s a gamble because, in the event that the supplement doesn’t work for you, you will have wasted your money on this product. The gamble is not particularly worth it for this product because the effectiveness of this supplement is a bit questionable given the ingredients. It would probably be much more beneficial for customers to search for supplements with scientific backing to ingredients and a guarantee.
