Only if you were running short of it. Does B12 shots give you energy? If a blood test puts your level low, bringing that level back up can lift the tiredness that came with it. If your level reads normal, you're buying a $25 vitamin, and the one trial we can hand you found no change in fatigue against a placebo.
We list our sources at the bottom so you can check us.
Build blood, mainly. The deficiency anemia entry on MedlinePlus, the government encyclopedia kept at the National Library of Medicine, opens on exactly that: Your body needs vitamin B12 to make red blood cells. Two lines earlier the same entry says what those cells are for. Red blood cells provide oxygen to body tissues. Run genuinely short of the vitamin and you end up anemic, and the symptom list on that entry reads Fatigue, lack of energy, or lightheadedness when standing up or with exertion next to a swollen tongue, pale skin and shortness of breath on the stairs.
Read that list in one direction only. Being low can leave you tired. It doesn't follow that being tired means you're low. And the injection has one job. The goal of treatment is to increase your vitamin B12 level. That's MedlinePlus on the aim of care, and there's nothing in it about raising a level that already reads normal.
Probably not, and the arithmetic is against it. MedlinePlus keeps a whole separate page for tiredness on its own, and it names the thing we're all describing. Fatigue is a feeling of weariness, tiredness, or lack of energy. Then the line that should change what you buy: Fatigue itself is not a disease; it's a symptom.
The causes it lists under that run long. Thyroid, heart, liver and kidney disease. Anemia. Infections. Sleep apnea. Depression and anxiety. Some medicines, chemotherapy, recovery from surgery. Then the plain lifestyle column: not enough sleep, staying up late, too much alcohol, too much caffeine, too little or too much exercise. B12 shortage is one entry on a page of them, and it isn't the likeliest one in a busy Tulsa household. On weeks of it the page is direct. If you have been feeling tired for weeks, contact your health care provider. Put your money toward that appointment before you put it toward our cooler.
They have, and the result is why we talk this way at the door. A randomized, double blind, placebo controlled trial published in Clinical Nutrition ESPEN took 95 adults who were worn out enough that it was disabling, every one of them with a B12 blood level in the normal range, and gave half of them 1,000 micrograms of B12 daily for eight weeks. The authors say up front what they were testing: big doses of B12 handed out for tiredness when the blood level already reads normal. Their measured result on the fatigue scale was no significant difference between the supplement group and the placebo group. Those 95 people all had irritable bowel syndrome or inflammatory bowel disease, so they aren't a stand-in for everyone with a long week. It's still the closest thing we've found to a real test of the question we get asked at the door, and it lines up with how the vitamin works. If your level already reads normal, the injection has nothing to raise.
No. We sell the injection and we'll still say so out loud on the phone.
What a visit here does is narrower and duller than the advertising. You get a full liter of fluid, which our own bag page says is the part that handles hydration, and Oklahoma heat books plenty of those every summer. Rehydrating is rehydrating. It isn't a vitamin lighting a fire under you.
The injection is a $25 add-on on any visit, and your first one is on us, no code, straight off the menu promotion. Five of the fourteen bags on our menu list methylcobalamin, the active form, already in the bag: Energy and Hydrate at $199, the $199 Migraine Cocktail, Prenatal Infusion at $179, Peak Performance & Recovery at $219, and The Complete Package at $399. So your nurse will ask before she pushes a second dose into the same arm for nothing.
Budget about an hour for the appointment, longer if you booked NAD+, since those are deliberately slowed down. One flat price holds across all seven cities on our list, Owasso, Tulsa, Jenks, Bixby, Broken Arrow, Collinsville and Claremore, with $25 tacked on if you are out in Sand Springs or Sapulpa. Nothing gets drawn up until a physician has looked at it, and the person knocking on your door holds a nursing license. If the injection is all you want and the four o'clock slump is your reason, you'll hear this article read back to you at the door, and then it's your call.
We took the stomach question apart separately.
Reading this is not medical advice, and nobody here has seen your bloodwork. A nurse can hand you a vitamin and a bag of fluid. Only your own provider can tell you whether being tired has anything to do with B12 in the first place.
