General Questions

What do we mean by ‘more science’?

Open tab

Research and efficacy are at the centre of everything we do - for us, it isn't enough to be 'good enough', we want to be more, to do more! So, how do we do that? At Medlab, although we see great value in using the research of others, we thought we would take it one step further. This is why we have our very own PC2 research lab where our incredible team research, experiment and test our vitamins and supplements.

And not only that, more science is more than just our lab, it's our clinical trials, our new, better and unique delivery platforms (shoutout to NanoCelle), our collaborations with universities and our dedicated team of scientists, doctors and researchers.

What is NanoCelle?

Open tab

NanoCelle is a unique delivery technology that is safe, effective and convenient, administered as a spray onto the oro-buccal membrane inside of the cheek.

The vitamin is in a nano-particle size so that it can be directly absorbed into the bloodstream. This enables the formulation to be lower dose with higher absorption, in contrast to ingested forms.

NanoCelle has been shown to have a higher absorption rate than tablets, capsules, gel capsules, dermal patches, sublingual (under the tongue) liquid, and intramuscular injections. By avoiding the digestion pathway, this technology is beneficial for those experiencing gastrointestinal or digestive complications.

What is the science behind NanoCelle technology?

Open tab

In NanoCelle, the vitamin is in a nano-particle size so that it can be directly absorbed into the bloodstream, significantly increasing solubility, absorption, bioavailability and stability

How we take vitamins actually matters!

Vitamins taken orally (capsules/tablets) are absorbed in the gastrointestinal tract and then pass through the liver on the way to the bloodstream - Up to 70% of a vitamin content may be lost within this process. If a patient has poor gut health and poor liver function, this alone can limit vitamin absorption that is taken orally (tablets/capsules) NanoCelle is designed to work around poor gut health and poor liver function 

The Nanocelle is a delivery technology administered as a spray onto the oro-buccal membrane (inside of the cheek) to deliver vitamins, avoiding the digestive system Nanocelle Technology converts fat-soluble and poorly water soluble compounds into highly water soluble particle. The water soluble nanoparticle is absorbed and transported into the bloodstream. Nanocelle technology has an approved patent, so is only available from Medlab Clinical (us!!).

How does NanoCelle's absorption compare to other ways of taking vitamins?

Mg Optima Relax

What are the key benefits of Mg Optima Relax?

Open tab

Mg Optima Relax promotes relaxation during times of stress and anxiety and supports healthy sleeping. It is scientifically formulated to have a positive effect on mood and cognitive performance and also works to aid muscle recovery, muscle relaxation and provide relief of muscle aches and pains.

How do the ingredients in Mg work together to increase GABA and promote relaxation?

Open tab

L-glutamine is the precursor to GABA production, it is the most abundant amino acid in the body.  Glutamine is first converted to  glutamate, which is key for a good cognitive performance, learning ability and memory.

Glutamate is then converted into GABA or we risk over exciting our neuronal cells.  When converting glutamate to GABA it is dependent upon the activated form of vitamin B6 (pyridoxal-5-phosphate P5P). Deficiency in B6 may contribute to glutamate not being able to convert to GABA which may result in anxiety, poor concentration and poor sleep.

Zinc influences the release of GABA by helping B6 activate, which also activates glutamic acid. A deficiency in zinc will leave glutamate not effectively converted to GABA, which increases an imbalance resulting in anxiety, mood disorders. 

Magnesium binds and activates GABA receptors, for those who have a deficiency in magnesium, the GABA receptors won’t be effectively activated and applied successfully.

When should I start to notice results?
