Fully Active Folate

90 Veggie Caps DRB-00262

Growth opportunity.

Named after the Latin word for leaf, “folium,” folate is an important B vitamin found in leafy greens that promotes healthy mood, memory and circulation and is important for human growth and development.* But since the body can’t make its own, and food sources aren’t well absorbed, folate is one of the most widespread vitamin deficiency across the globe. That’s why supplements are critical to maintaining optimal levels.* Our unique formula incorporates Quatrefolic®, the most advanced form of metabolically active folate. The result is an efficient, easily absorbed essential nutrient that can boost brain health and beyond.*

I have a terrible time absorbing B vitamins, and this brand is already metabolically available, so that my body doesn't have to break it down before being able to use it! It's great, and isn't an overly expensive source of extra folate! I'll definitely be buying this regularly!

I felt an immediate easing of anxiety when I started this product. My sleep has improved somewhat—sleeping for longer periods at a time and deeper sleep.

About to buy my 3rd bottle. I've taken this daily before I got pregnant and throughout my pregnancy. I noticed on days I missed, my emotions were all over the place. I know for women, folate is essential. Especially when you are pregnant!
