Source Naturals Methylcobalamin Vitamin B-12 5mg Cherry Flavored - 30 Lozenges

I'm in my 60s and many years ago a manicurist recommended B-12 for my fingernails. Figured I'd try it and I found that it stopped my nails from splitting. Since than I read that B12 deficiency has been estimated to affect about 40% of people over 60 (and a surprising number of people younger that 60). Apparently such a deficiency can have many serious consequences. I've used this brand and this amount for a number of years now and find that it is easy to take. I can see the good effect it has on my nails, so I figure it must be having a similar good effect in other areas that I can't gauge as easily. I end up not taking it everyday, just because I don't always get around to it. In the last tests I got, I was slightly over the range for b-12, but my doctor said it was not a problem. This is one of the few vitamins I feel is worth taking.

Vitamin Basics & Tips

Vitamin B12 plays a critical role in nerve function, red blood cell formation, and DNA synthesis. The reviewer’s experience highlights its impact on nail health, a lesser-known benefit linked to B12’s role in keratin production. Approximately 40% of adults over 60 suffer from B12 deficiency, often due to reduced stomach acid impairing absorption. Symptoms range from fatigue and cognitive decline to irreversible nerve damage if untreated.

While supplements like sublingual tablets (as mentioned here) bypass absorption issues, excessive intake can lead to elevated blood levels. However, the body excretes excess B12 through urine, making toxicity rare—hence the doctor’s reassurance. Dietary sources like meat, fish, and fortified cereals are ideal, but supplements become vital for aging populations or those with dietary restrictions. Regular blood tests help monitor levels, ensuring optimal intake without over-supplementation.
