This is the best vitamin B1!
Verified Purchase
This is the best vitamin B1! I think its effectiveness is comparable to injections. One or two tablets under the tongue and the neuralgia subsides.

Very good!!
Verified Purchase
The product size and packaging are good. It has benefits, the aroma is normal, I hope it's of good quality. I don't know if there's an age limit for use. The composition of this essential oil is used to moisturize and nourish sensitive skin. It's a good product; I haven't opened it yet, but it's for the skin and wrinkles or reducing inflammation. I don't know if it's anti-aging, but the resveratrol must have benefits. The package size is good for the ingredient; I hope it's a quality supplement that says it's good for diet or training if you're into fitness. It has a good texture, gives energy, and the folic acid is good. It has a good flavor, helps the nervous system, metabolism, and enhances its effects and benefits. The box says it reduces redness from niacin.

Interesting thiamine
Verified Purchase
These tablets are placed under the tongue and dissolve in seconds, ideal for those who have difficulty swallowing but also for those, like me, who seek different absorption methods: the on-tongue form allows the thiamine to enter the bloodstream more directly, bypassing the digestive system. The taste of thiamine is horrible, but these tablets are tolerable because they are sweetened.

Weichorp Vitamin B1 is one of those supplements that truly works. I noticed results very quickly: my inner fatigue goes away, and I feel more energy, clarity, and focus. It's especially beneficial for those who experience weakness after eating, anxiety, dizziness, or nervous system issues. Weichorp's formula is pure, without unnecessary additives, easy to digest, and doesn't weigh down the stomach. I liked that it doesn't leave me feeling "overwhelmed" like some supplements—the effect is gentle, stable, and physiological. If you have a B1 deficiency or symptoms of deficiency (weakness, tremors, fatigue, brain fog, irritability), this option is one of the most reliable. I recommend it as a safe and effective source of thiamine.

Very good
Verified Purchase
Very good quality like all products from the Superior Source brand, valuable ingredients, good capsules and package size, you can see the effect immediately because it brings more energy, it helps the nervous system to work better, it is really effective, taste is not particularly good, but because of the effects it is definitely worth trying.

I can recommend
Verified Purchase
I have to buy a lot of things every month. Reviewing them individually gets very frustrating. That's why I created a special template. If you see this paragraph, it means I'm very satisfied with this product. Subsequent buyers can buy it without hesitation. Of course, I'm not an irresponsible buyer. If the product isn't good, I'll take the time to comment on it.

Great
Verified Purchase
I really liked the format - small tablets quickly dissolve under the tongue, no need to wash them down with water. Convenient to take with you. I felt the effect quite quickly: more energy, less fatigue. High-quality composition, without unnecessary additives. Excellent price-quantity ratio - lasts a long time. I will order again.
