Review: Life saver! I feel so much better. - These are of great quality! My alergist recommend this specific kind because it's easier to absorb. I have celiac diseaseand have been trying to find supplements that work for me. These work amazingly! I can feel the difference with in weeks of starting them. I had to stop recently due to financial issues and my energy decreased, I started putting on weight despite not eating much. Felt over all blah. Within a couple weeks my energy came back, that yucky all over feeling went away, my mood is better too. I don't get upset stomach with these either. I got them with all other types of B vitamins taken and no nasty aftertaste. Overall value is worth it for the health benefits.
Review: Good quality - Quality supplement & small size makes capsule easy to swallow.

## Questions & Answers

**Q: question for the seller - Is prothera and klaire labs the same?  The photoshows one and the label is another**
A: I cannot answer that one.

**Q: The prothera and klaire labs % daily value is different. kl is much higher. what did they add?**
A: The new FDA labeling requirements include something called "Dietary Folate Equivalent" (DFE) - the same amount of "Active" folate is labeled at the higher "DFE" amount - the amount has not changed, the FDA labeling requirements have changed. This reflects the fact that "Active" folate is more bioavailable than dietary folate.

**Q: Is the prothera or Klaire labs?   Label is one and picture is the other.**
A: I assume it’s pro theta lab but honestly I don’t know.

**Q: does anyone know what these b-vitamins are made of ?**
A: Check the nutrition label on Amazon. It has a full list of ingredients.
