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).
Supplementation with B-12 Intrinsic Factor:
• Supports nervous system health
• Supports red blood cell production
• Supports energy
• Supports metabolism of fats and carbohydrates

Awesome quality glow balls
Color: I) 8-Pack (2.5" Balls)
I have bought every glow ball on amazon many times over for my german shepherds. My longest lasting balls have been the chuck-it, they seem to glow longer and not get destroyed but are expensive. These glow balls are our new favorite and not only because of the low price. They hold a good glow longer are heavy duty and fit the chuck-it thrower perfectly. I am stocking up on these. Shipping was also next day so it's 100% buy on these.

Glow in the Dark Balls
Color: 2-Pack (3" Balls)
These balls are ok, not great. The reason they didn’t receive 5 stars is because they are hard/stiff, harder to throw & heavier than the the “Chuck It” glow in the dark balls. They did not hold up to heavy chewers as well as the aforementioned balls.

Bulky
I was a little disappointed in how bulky these were and seemed hard to get on. If you can get past this they do seem to work good. Hands do seem softer and a bit healthier.

Really moisturizes hands
These gloves really work. My cuticles and hands alway seem dry. I used these gloves the first night I received them and my hands were really smooth afterward. When I get in bed at night, I play on my computer and iPad, and these gloves are perfect. The end of the index finger is designed to be used with a phone, computer, and iPad. Make sure you push the end of the fingers on the gloves all the way down to the end of your fingertips; otherwise you will not be able to use them with a device. I find they work better with my iPad than my computer. I have not tried to use with my phone. The gloves are not uncomfortable, but I found they are not comfortable to wear all night, so I just try to wear them about an hour every night. I wish I had these gloves about 20 years ago and my hands would probably look like a 20 year old.

So much pain
I had to remove these after less than 5 minutes as they caused such intense pain. The gel clings to your skin even with the lotion and tightens around your hands cutting off circulation. They have been off for about half an hour and my hands still hurt. I was so excited as I really like this brand in general. Very disappointed. Be very aware when buying.
