great
Verified Purchase
This time, I repurchased my favorite vitamin B innate complex, which was on sale for 20% off. The ingredients and effectiveness are truly excellent. I repurchased it just a few days after my first purchase. While some say vitamin B can be manufactured chemically, I believe vitamin B innate is a natural ingredient, making it trustworthy.

Cool
Verified Purchase
A high-quality product. The ingredients are perfectly selected. No adverse reactions. The packaging is large, so it lasts a long time. The capsule size is average. The flavor is neutral. Fast, undamaged delivery. Contains only beneficial, natural ingredients, including folic acid. Improved bowel function and metabolism. Noticeable results within a week. Improved nervous system function and reduced anxiety. The effectiveness of this vitamin is undeniable.

It contains folic acid
Verified Purchase
My ophthalmologist recommended taking vitamin B, and I'm taking it now. I usually take Now Foods' B-50, but this product is quite expensive, so I bought it during a sale. It's easy to take because I don't need to take folic acid separately. I've never experienced a nasiacin flash, and I feel the quality is good. Since it contains the main components of vitamin B, I'd like to take it when I can get it cheaply.

The quality is good, the packaging is large, the taste is absent, I take it as a supplement for 10 days in a row, then a 10-day break, and so on.

The best of the best!!!
Verified Purchase
The quality of this brand is at its best (as is the price, this is the only minus that I can note)! Not only the vitamin complex, but also all the raw materials used meet the requirements and standards and have the appropriate certification! The tablets are not large, do not have a pungent smell, are easy to swallow and one per day is enough (but the dosage is very individual, so it is better to consult a doctor), all forms in this version have a good form for absorption. The packaging is large, so it will last for a long period of time, we take it as a course for prevention and stressful periods, the effect is noticeable after a few days of taking it! If you are looking for a really good and high-quality complex, I recommend that you pay attention to this one! When it runs out, I will buy it again

I bought it because I kept feeling tired.
Verified Purchase
I bought it because the price was reasonable and the content and quantity were just right. I'm feeling tired, so I'm going to try taking vitamin B supplements regularly. I hope it works.
