ThiActive B-Complex provides a full spectrum of nutritional B vitamins to complement the action of thiamine (vitamin B1) within the cell, including two different forms of thiamine with high bioavailability.
Benfotiamine is an S-acyl derivative of thiamine known for its ability to improve blood sugar management and support peripheral nerve function. Thiamine Tetrahydrofurfuryl Disulfide (TTFD) contains one thiamine molecule bound with a sulfur-mercaptan group, which provides it with unique properties.
The molecular structure of these two thiamine derivatives 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.
To support the process of methylation, this complex includes active folate in the form of L-methyl folate, along with non-methylated folate in the form of folinic acid (calcium folinate). Similarly, two types of active vitamin B12 are provided in the forms of methylcobalamin and adenosylcobalamin.
This formula also contains the activated form of vitamin B2 (riboflavin-5-phosphate) and vitamin B6 (pyrixodal-5-phosphate).
As an additional ingredient, D-ribose is included as a sugar precursor to promote cellular ATP production.
This product was designed for people who feel that they benefit from methylated vitamins in their active form.
How to use
- Start with one capsule per day in the morning with or without food. This can be increased to 2 capsules per day to reach a maximum dose.
- Avoid coffee/tea consumption either one hour before or two hours after.
- Avoid taking this product in the afternoon/evening, as it may interfere with sleep.
For those who consider themselves sensitive to methylated B vitamins, consider using our non-methylated B complex Thiavite.
- In some individuals, supplementation with products containing thiamine tetrahydrofurfuryl disulfide (TTFD) can induce a temporary worsening of certain symptoms such as fatigue, brain-fog, and digestive bloating or gas. This usually lasts for around one week, and is referred to as the “paradoxical reaction”.
- For those with sensitivity to sulfur-containing compounds, this product may not be suitable.
Frequently Asked Questions
It is recommended to start with one capsule per day. Increase gradually to 2 capsules per day over the space of one to two weeks. If one capsule is best tolerated, then remain at 1 capsule per day.
This complex is best taken in the morning time or early afternoon. If taken in the evening, it may disrupt sleep. This supplement should be taken at least 1 hour before, or two hours after consuming coffee or green/black tea.
This is best taken with food but can also be taken away from food depending on individual preference.
Initially some people can experience a “paradoxical reaction” with thiamine supplementation. This might include a temporary period of increased fatigue, brain-fog, and poor concentration. This reaction usually subsides within a few weeks. If symptoms remain, discontinue this supplement.
2 capsules per day
This B complex is designed to complement Thiamax, our supplement containing a bioavailable form of thiamine known as TTFD. Furthermore, magnesium and other mineral cofactors are advised when supplementing with thiamine, each of which is included in our mineral formula ThiAssist.

For me, this product did not work out. I took one capsule and had a bad reaction. Tried again the next day with the same result so I stopped trying. This is not to say it's not a good product, just not good for me. I may try another product from this company because I like the fact there are no fillers.
