Factors for Support of B-12 Bioavailability
Vitamin B12 is a water-soluble vitamin needed for normal nerve cell activity, DNA replication, and production of the mood-affecting substance SAMe (S-adenosyl-Lmethionine). Vitamin B12 acts with folic acid and vitamin B6 to control homocysteine levels.

Absorption of vitamin B12 is reduced with increasing age. Some research suggests that elderly people may benefit from 10 to 25 mcg per day of vitamin B12. One study of elderly people with vitamin B12 deficiency suggested that as much as 500 to 1,000 mcg of vitamin B12 per day might be necessary to achieve optimal vitamin B12 status. Vitamin B12 status was measured in this study using a sensitive laboratory test (the plasma methylmalonic acid concentration).

Best mascara I've tried!
Color: VERY BLACK, Size: 0.24 Fl Oz (Pack of 1)
This is hands down my favorite mascara! It gives amazing length and volume without feeling heavy or clumpy. My lashes look so much longer, and it lasts really well throughout the day. I keep coming back to this one because it works better than many more expensive mascaras I’ve tried!

Good Everyday Mascara
Color: BLACKEST BLACK, Size: 0.24 Fl Oz (Pack of 1)
I’ve been using the Maybelline Lash Sensational Sky High Washable Mascara for a couple of weeks now, and overall I’m really impressed. The biggest standout is the length. It genuinely makes my lashes look noticeably longer without needing multiple coats. The flexible brush does a great job grabbing even the smaller lashes, and I didn’t have much issue with clumping as long as I applied it carefully. It also holds a curl better than I expected for a washable formula, which is a big plus. Another thing I appreciate is how lightweight it feels. My lashes don’t get that heavy, stiff feeling some volumizing mascaras can cause. It’s also easy to remove at the end of the day, which makes it great for everyday use. That said, it’s not perfect. While it does add some volume, if you’re looking for a very bold, thick lash look, you might find it a bit lacking. I also noticed a tiny bit of smudging under my eyes after a long day, though nothing too extreme. Overall, this is a great mascara for length and a more defined, lifted look. I’d definitely repurchase, especially for daily wear, but I’d pair it with something more volumizing for special occasions.

Absolutely love this Maybelline mascara! It makes my lashes look longer, fuller, and more defined without clumping. The formula lasts all day and doesn’t smudge easily. It’s affordable, easy to apply, and gives such a beautiful lash look.”

A perfect natural glam mascara
Color: PLUM TWILIGHT, Size: 0.24 Fl Oz (Pack of 1)
I have been searching for my ultimate, every day mascara for at least 10 years & I actually tried this one about 4 or 5 years ago (not in this shade though) and I remember it being a strong like at the time but not “the one”. Buuut this might be the one. Went on smoothly with minimal clumping. Elongated and curved my lashes upwards without using an eyelash curler. Held up for 9 hours in humid, sticky conditions and is still going strong. No flaking, smudging or transfer. I do wish the brush was different, or had longer bristles at least, but not enough to dock a star over. The plum shade is gorgeous and veers toward black in some lighting but has just enough color to enhance the eyes. It didn’t add a ton of volume, but enough to be noticeable and I actually prefer that because I have sensory issues with my eyes and that is why I sadly can’t do falsies. All in all, this is a 5 star, every day, natural glam mascara and now I want to try the green.
