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.

Important information:

  • 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.

    I was diagnosed with fibromaylgia 2008. After years of debilitating pain finally found the root cause in 2020. It is chronic lyme. I took this and all the pain came back alog with daily migraines. I have the mhtfr gene mutation. This is too high a dose for those with gene mutation. Bed ridden for five days and then stopped.

    I started slowly out precaution - on day 1-4 i was only taking the ThiActive B and on day 5 i started Thiamax - so far i haven't had any side effects and I’m gradually feeling the improvements.

    Day 1 acid reflux stopped and garlic/sulphur intolerance almost gone

    Day 3 excessive hair fall stopped

    Day 5 alot more energy and less yawning

    Still making daily observations and will start taking Thiamega

    I have a range of longterm thiamine deficiencies - hyper thyroid, repetitive kidney stones, inability to control hydration status in the body and consumption of potassium, cant processes oxalates, occasional histamine intolerance, FODmap diet intolerance, sulphur intolerance, loss of appetite and loss of muscle mass, acid reflux , low acid, sibo, gallbladder stones, persistent constipation, hemorrhoids, nutritional deficiencies despite liposomal supplementation, pre-diabetic status, high LDL and cholesterol and cardiac risk markers, checst pains, occasional anxiety, early sign of pre-menopause. It all started with low stomach acid and over the years i compiled all the other side effects of long term indigestion and insufficient acid for 25 years - additional symptoms every 3 years and no protocol helped long term. I can say thiamine is the missing link as now without hcl or acv i feel im able to produce enough acid to digest the meal and i may stop taking enzymes soon as the bosy will be capable over time to get produce its own if all stem cell signaling is functioning well after thiamine supplementation.

    I also had to treat a scar tissue on the stomach meridian that i had for 26 years.

    Everyday i take with them a spectrum of 7 types of Magnesium 500-750mg daily, zinc, selenium, copper, Molybdenum, Manganese, copper, calcium AKG, vit DK2 , liposomal vit C and liposomal PC oil and omega 3.

    p.s - I had to do energy clearing to remove the negative energetic impact from the flights and heat of transportation that took 10 days to reach me. After clearing I found that the content of the material was resonating 100% with a healing vibration for ThiActive B and 75% resonance with healing vibrations for Thimax and Thiamega - im guessing some damage happened from the heat as it reached me very hot.

    The product works better than other combination B vitamin products I have tried. There is a noticeable effect as far as being less tired and less brain fog during the day.

    The product caused a terrible interaction with the medication Metoprolol for, high blood pressure and heart arrhythmia. I staggered the consumption of the supplement by taking it 6 hours after medication. I tried taking 1/4 or 1/2 of the recommended dosage of the supplement. The reaction continued. I could not continue to use the supplement. Nearly all of the product has been wasted.

    I’ve only been on Thiamax and Thiavtive B for about a week and I have lots of energy and I’ve been more productive. Just make sure you take a some fat and early in the morning bc I’ve had a couple very late nights if I take these supplements after lunch . Ty , I’m giving it 60 days to see how I feel then .

    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.
