The foundations of our brand

What makes our food supplement drink mixes different and why are we so passionate about improving your health with L-Arginine & L-Citrulline?

Unlike other food supplements, all our drink mixes start with a base of L-Arginine and L-Citrulline. We’ve added to these powerful amino acids – specifically chosen vitamins, minerals and proteins – to create a range of powerful dietary drink mixes, with great specific health benefits.

Something extraordinary happens when the amino acids L-arginine and L-Citrulline are taken together in a precise mix ratio in supplementation form. L-Arginine and L-Citrulline work in conjunction, enabled by the oxygen in our cardiovascular system, in a reaction catalysed by the enzymes nitric oxide synthases, to produce nitric oxide gas – increasing (and helping to maintain) the levels in our body of this amazingly ‘beneficial to our health’ molecule.


The mix ratio of 5g of L-Arginine with 1g of L-Citrulline has been scientifically validated in research papers by reputable organisations, to be an effective mixed dosage to function as a precursor to the production of nitric oxide in the body. Lower doses of each of these amino acids in the combination and the synergistic process has not proven as efficient. This specific mix ratio also results in the nitric oxide produced remaining in the system for a longer period, due to changes in the molecular structure of the L-Citrulline within the process – allowing maximum uptake and therefore maximum benefit.

Why is the nitric oxide gaseous molecule so important for ensuring our products deliver maximum benefit

Nitric oxide is a vasodilator that relaxes our blood vessels, ensuring a nutrient and oxygen rich delivery of blood to every part of the body, including the scalp. The production of this gaseous molecule by the amino acids L-Arginine and L-Citrulline supports the perfect ‘delivery system’ for all the complementary ingredients contained within our Food Supplement Drink Mixes and helps the vitamins, minerals, proteins, and polyphenols to get to where they need to be.


Collagen, Vitamins C, D3 & K2, Biotin, Zinc, Beetroot, Resveratrol and Grape Seed Extracts have all been carefully chosen by our team of expert nutritionists for the benefits they can deliver in improving and maintaining cardiovascular and hair health. Alongside the benefits from L-Arginine and L-Citrulline alone – and the processes these two amino acids initiate resulting in the production of nitric oxide – every ingredient contained in our formulations has the best chance to ensure impressive results. Results our customers are delighted with!
