Thiamega, a leading high dose thiamine (Vitamin B1) supplement manufactured in the United States, provides the vitamin in four different forms, each possessing unique properties.
Three of the derivatives contained within Thiamega are synthetic and were originally developed in Japan to achieve higher availability than ordinary thiamine salts. Benfotiamine, sulbutiamine, and TTFD may increase brain levels of thiamine, support cognitive function and the central nervous system health.
Thiamega Dosage – How many capsules per day?
- 1 capsule per day in the morning, with or without food
- 5 capsules per day, spread across the day, is the maximum dosage for Thiamega
- Avoid coffee/tea consumption either 1 hour before or 2 hours after taking Thiamega
- Avoid taking in the afternoon/evening, as it may interfere with your sleep cycle
Before you start taking Thiamega
Thiamega contains high dosage of thiamine derivatives. This may cause temporary side effects like insomnia, anxiety, fatigue, brain fog, and trouble concentrating, especially in individuals who are not accustomed to high dosage.
If symptoms persist for more than a few weeks, discontinue immediately.
Thiamega may not be suitable for individuals with sensitivity to sulfur-containing compounds.
Thiamega High Dose Thiamine Protocol – What does it contain and who will it benefit?
Thiamega provides a high dose of Thiamine, providing Vitamin B1 in four different forms, each with unique properties. Each Thiamega capsule delivers a total of 400 mg of thiamine, composed of thiamine hydrochloride, benfotiamine, sulbutiamine, and TTFD. This combination may serve to enhance brain function and support cognition, along with promoting healthy energy metabolism.
This high dose thiamine supplement is free from fillers and excipients, highly bioavailable and capable of penetration into the brain and central nervous system.

Benfotiamine, an S-acyl derivative of thiamine, is well known for its ability to improve blood sugar management and support peripheral nerve function.
Sulbutiamine contains two molecules of thiamine bound together by a disulfide bond.
TTFD or Thiamine Tetrahydrofurfuryl Disulfide contains one thiamine molecule bound with a sulfur-mercaptan group, which provides it with unique properties.
The molecular structure of these thiamine derivatives in Thiamega, allows them to pass through intestinal and cellular membranes without the requirement for a transport system. Once inside the cell, they deliver thiamine which can be activated and used as a cofactor in important biochemical processes.

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.
Returns
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.
