B12? Now I get it!

When my new doctor here in Missouri told me I needed B12.....badly, I thought ok fine.
He gave me a list of vitamins to replenish what having Alpha-Gal had depleted from me and also said
he wanted me to get B12 shots once a month in office.
It took some time but I began to notice an increase in energy stamina. Like working in the yard went from
running out of energy after an hour or so to now working hard (mowing and weed whacking) up to nearly 5 hours at a time.
I even take care of my neighbor's yard now who has to have knee replacement. BTW, I am 73 yrs old.
When he said I need B12 to help with energy, I envisioned like bursts of it. Nope it was a steady increase in stamina
energy. Steady pace, focused and just get it done thing.
The shots are the key over taking just a tab orally. I am glad I went his way and not the route of energy drinks and
water with electrolytes like others advised me to do.

Yes, I swear by B12. My doctor won't prescribe the injections, and because you are correct that it's most effective in liquid/injectable form, I buy these

Wait what? Not as effective with the injectables? Why do you think that is?
Are those liquid drinks a stronger dose?

Pills are not as effective as injections. When you take a vitamin B12 oral supplement, only a tiny portion is absorbed by your body, typically only 1% or 2%, due to limited absorption capacity in the stomach, and the rest is just eliminated when you go to the bathroom. So they're literally a waste.

In liquid form, the stomach can absorb 10% to 50%, the liver can store about 12%, and the rest is eliminated.

Injections are optimal. But not as optimal as food sources, though.

(per my internal medicine doctor)

My doc prescribed B-12 but told me I can get the exact same thing OTC, so I order them from Amazon.
The kind I get dissolves under the tongue, and I think it really helps.

I think your doctor steered you wrong. It's not the exact same thing unless you double or better the dosage. For example, if 1,000mcg IM worked well, then you want at least 2,000mcg of the sublingual.

Researchers say that both oral and sublingual tablets have a 1 to 2% absorption rate. In other words, your body will only absorb 1 to 2% of the B12, and the rest is eliminated. And the sublingual tablets cost about 50% more than oral tablets, depending on the brand.

If I remember right, injections have about a 50% absorption rate, but then you have the cost of doctor visits. But, imo, it's cheaper in the long-run, because injections are far a more efficient way to deliver the goods.

I drink the liquid form, which has an absorption rate of ...I think it's 25 to 30%, depending on the brand. I know it's far more than oral tablets (and, obviously, sublingual tabs). It's not cheap, though. I pay about $2.50 to $3.65 per bottle, depending on the brand, and drink 1 or 2 a day. But it's efficient and effective.

Of course, if you're happy with what you're using and it works for you, that's cool! I'd keep doing it, that's for sure.
