Why B12 Shot.
Energy + metabolism
B12 is a cofactor in energy production and red-blood-cell formation — correcting a low level often lifts fatigue.
Supports the GLP-1 journey
Reduced appetite on a GLP-1 can lower B12 intake; a weekly shot keeps levels topped up.
Mood + nervous system
Essential for myelin and neurotransmitter synthesis — deficiency can show up as low mood and brain fog.
How it works.
Weekly injection
Quick intramuscular or subcutaneous shot — at home or in-office.
Direct absorption
Bypasses the gut, so the full dose reaches circulation.

How it actually works.
Vitamin B12 (cobalamin) is an essential cofactor for DNA synthesis, red-blood-cell formation, and myelin maintenance. Injection bypasses the gut, delivering the full dose to circulation — useful when intake or absorption is reduced.
Who it's for
- Adults with low or borderline B12
- Fatigue or low mood with a low level
- GLP-1 users with reduced intake
- Vegetarian / vegan diets
Not for
- Known cobalt or cobalamin allergy
- Leber's hereditary optic neuropathy
Side effects, up front.
Common
- •Mild injection-site soreness or redness
- •Transient warmth or flushing
Call your clinician
- •Rare allergic reaction (rash, itching, swelling)
- •Rarely, low potassium when treating severe deficiency — your provider will monitor
Generally very safe
B12 is water-soluble with a wide safety margin. Stop and contact your provider for any rash, itching, or swelling after a dose.
Money-back if not approved
Full refund if our medical team determines you're not a fit.
Questions, answered.
Why a shot instead of a pill?+
Injection bypasses gut absorption and delivers the full dose — helpful when appetite or absorption is reduced.
How fast will I feel it?+
If you were low, energy often improves within days to a couple of weeks.
Can I get too much?+
B12 is water-soluble; excess is largely excreted, so toxicity is very rare.
