Ingredients: 7 all natural, proven ingredients that make all the difference

  • L-Theanine - L-Theanine is an amino acid found in Camelia Sinensis (AKA green tea), which has a unique calming effect. Theanine modulates the glutamate system as well as altering the levels of monoamines (an increase in dopamine and serotonin) and GABA. Theanine is known for being calming but not to the extent that it will cause drowsiness, and is known to pair well with other stimulants. Studies: PMID: 31623400, PMID: 9566605.
  • Emoxypine - Emoxypine, also known as Mexidol, is a bioactive compound originally synthesized in the Research Institute of Pharmacology in Russia, it functions as an antioxidant which resembles pyridoxine, also known as vitamin b6. Emoxypine features an impressive array of mechanisms including cerebral blood flow enhancement, anxiety reduction, anti-stress, anti-seizure, anti-inflammatory, and neuroprotection. Emoxypine’s ability to increase GABA sensitivity and its multitude of anti-inflammatory properties are thought to be responsible for its anxiolytic action. Studies: PMID: 25894772, PMID: 11544797.
  • Lemon Balm Extract - Lemon Balm, also known as Mellisa Officinalis, is a perennial belonging to the mint family, most commonly prepared as a tea. It provides anxiety relief and mood lifting effects. These properties are thought to be due to Lemon Balm's phytochemicals ability to inhibit the degradation of GABA, via its inhibition of GABA-Transaminase, the enzyme responsible for the breakdown of GABA. Lemon balm is also shown to possess high phenolic content and antioxidant properties. Lemon balm infusion improves plasma levels of catalase, superoxide dismutase, and glutathione peroxidase and a marked reduction in plasma DNA damage, myeloperoxidase, and lipid peroxidation. Studies: PMID: 25360512, PMID: 34449930, PMID: 27620926.
  • Eria Jarensis Extract - Eria Jarensis is a not very well known plant that contains the phenethylamine compound known as NN-Dimethylphenethylamine (N,N-DMPEA), N,N-DMPEA is a ligand at TAAR1 similar to amphetamine, and also binds to the 5-HT1a receptor as an agonist, and was also shown to inhibit MAO-B, an enzyme that has an effect on the metabolism of dopamine downstream via GABA synthesis inhibition, which can increase the levels of dopamine. 5-HT1A receptor agonists may reduce the activity of serotonergic projections that inhibit dopaminergic nigrostriatal neurons, therefore increasing dorsal striatal dopamine levels. Studies: PMID: 15906386, PMID: 34244591, https://pubchem.ncbi.nlm.nih.gov/compound/N_N-Dimethylphenethylamine#section=BioAssay-Results
  • Ashwagandha - Ashwagandha is a plant native to India which belongs to the nightshade species. Use of this plant goes back at least 6000 years ago as staple traditional medicine in India. It is known for its potent calming properties and features a wide array of benefits including but not limited to reducing inflammation, balancing blood sugar, improving memory, and boosting immune function. Ashwagandha’s mood effects are primarily through GABA/Glycine activation, as well as modulation of the serotonergic system. Studies: PMID: 22754076, PMID: 37111543, PMID: 24268297.
  • Agmatine Sulfate - Agmatine belongs to a class of compounds called Biogenic Amines and is also synthesized in the body from Arginine, an Amino Acid. Agmatine has the potential to reduce anxiety and depression-like symptoms and can also reduce pain and improve cognitive health. Its cognitive health promoting properties stem from its ability to provide neuroprotection in the form of antioxidant, anti-inflammation, and anti-apoptosis actions. Agmatine is also shown to reduce drug cravings to multiple drugs including alcohol, opioids, and amphetamines. Agmatine is also shown to have a rapid antidepressant effect via a similar mechanism achieved in ketamine therapy. Studies: PMID: 36709008, PMID: 27161447, PMID: 27232669, PMID: 34888168, PMID: 28786346, https://doi.org/10.1016/j.brainres.2020.147045
  • Sabroxy (Oroxylum Indicum) - Sabroxy is a patented extract standardized to contain a minimum of 10% oroxylin A, 15% baicalin, and 6% chrysin. The main focus of this standardized extract is oroxylin A, a dopamine reuptake inhibitor. Inhibiting dopamine’s reuptake in the brain causes extracellular dopamine not absorbed by the postsynaptic neuron to be blocked from re-entering the presynaptic neuron. This leads to increased levels of extracellular concentrations of dopamine and increase in dopaminergic neurotransmission. Another example of a dopamine reuptake inhibitor is cocaine or methylphenidate (ritalin), although their effects are much more potent. Baicalin, also found in Chinese and American skullcap, is a flavonoid which increases gabaergic activity via acting as a positive allosteric modulator, which increases the receptor's response to endogenous GABA. Sabroxy is also shown to increase BDNF (Brain Derived Neurotrophic Factor), BDNF is responsible for neuroplasticity which is essential for learning and memory, and also regulates neurotransmitters. Studies: PMID: 26788077, PMID: 34531736, PMID: 35656442, PMID: 18723037, PMID: 23045656.

Shipping Issues, Delays, Lost Parcels etc.

At MandiMart we pride ourselves on our same-day dispatch and fast delivery. We are constantly on the lookout for ways to improve our delivery service and avoid delays for our customers.

It is your responsibility as the customer to ensure you have entered the correct shipping address. When you place an order, you will be sent a confirmation email confirming your order details. Your address and the product details are included in the order details; this is your opportunity to correct any possible mistakes with your order. If you become aware of errors with your order, please make us aware at the earliest possible time by sending an email to MandiMartLimited@gmail.com. We will endeavour to alter your order before it is dispatched. Unfortunately, if your order has already been packed and labelled at our warehouse, we cannot affect it in any way. We cannot be held responsible for any issues that arise due to the incorrect information you have provided.

While we try our absolute best to minimise any shipping errors, we are only human. In the event we have sent you the wrong product, we believe that we have caused enough inconvenience through our mistake, and as a result of this we will dispatch the correct product to you at the next available opportunity, irrespective of whether or not you have returned the incorrect product at that moment. However, we do ask that you return the incorrect product promptly, but at your leisure. Failure to return the incorrect products will incur an invoice and subsequently debt collection as required. 

If you have not received your order after the expected delivery guideline has passed, please contact your local post/delivery office, and quote your tracking number to them. In 90+% of cases a ‘failed delivery attempt’ has been made but the postman didn’t leave a card to let you know this. If the parcel is indeed at the local delivery office you will be able to re-arrange delivery or collection of your parcel via an online portal on the carrier’s website, or by contacting the local delivery office directly.

Unfortunately, we are not able to guarantee delivery or the time/date that our carrier will plan to make the delivery – this is out of our control. If you parcel is delayed or lost you can rest assured that we will do everything in our power to help you trace your lost parcel. This will include following up tracking numbers and contacting carriers for further clarification if the tracking information is not explicit. MandiMart cannot accept responsibility for delays or losses caused by carriers until the ‘claims waiting time’ has expired. Until this has happened the only message we will receive from carriers is to wait. After this time, we are more than happy to begin a complaint/claim against the carrier for the delay/loss of your parcel.

If you have entered a ‘SafePlace’ for your parcel to be left (i.e. when you are not present to accept the delivery) and the carrier states that they have left the parcel in the specified ‘SafePlace’, then MandiMart cannot be held responsible for any losses that you have experienced through using the ‘SafePlace’ service.


We understand that your supplement requirements are subject to change and, as such, you may occasionally need to return unused/no longer prescribed products. We offer a ‘no contest’ return policy if the product is in reasonable expiry date, in its original condition, unopened with the security seal still in place and the return is initiated within 90 days of the order being placed. If it has been longer than 90 days, send an email and we will decide this on a case-by-case basis.

We will process a refund once we have received the returned product, and inspected its condition. MandiMart accepts no responsibility for returns that are lost or damaged en route to our address. For this reason, we strongly recommend using a tracked/registered service and ensuring the products are adequately protected, as required.

MandiMart cannot accept opened, unsealed products for return in any situation other than a (possible) manufacturing defect. In this situation we require the product to be returned to us and then we will converse with our supplier/manufacturer as to whether a manufacturing defect is present in the product. This could include returning the product to our supplier/manufacturer. If a manufacturing defect is present then you will be issued a new product replacement or a refund, whichever you should prefer. Please note that the return shipping is to be paid by customer and only on discovery of a manufacturing defect will this be refunded. If there is no manufacturing defect present you will not be refunded nor will a replacement be sent to you.

While we continually strive for perfection, we are only human and mistakes will happen from time to time. If we have mistakenly sent you the wrong product, we are more than happy to cover the cost of returning this wrong product to us. We believe that you have been inconvenienced enough through no fault of your own, and as such should not have to pay for the return, or wait until the initial product is returned before the correct product is dispatched. We will immediately dispatch the correct product for you, with no regard to whether we have received your product return. However, in the instance that you have ordered the wrong product or no longer require the product you have ordered, we would expect you to fund the return yourself.
