What it does

More energy. Sharper focus.
Better every day.

B12 is involved in over 100 enzymatic reactions in the body. When levels are low, which is surprisingly common, the effects show up in your energy, mood, and cognitive function. Results may vary.

Sustained energy

B12 is essential for converting carbohydrates, fats, and proteins into usable cellular energy. Deficiency is one of the most common, and most overlooked, causes of chronic fatigue.

Mental clarity

B12 supports the myelin sheath that insulates nerve fibers and the neurotransmitters that keep your mind sharp. Low levels are strongly associated with brain fog and mood disruption.

Better absorption

Oral B12 supplements absorb poorly, often under 1% for high doses in people with absorption issues. Subcutaneous injection delivers the full dose directly into circulation, bypassing the gut entirely.

Red blood cell support

B12 is required for healthy red blood cell formation. Without adequate B12, red blood cells become abnormally large and fail to carry oxygen efficiently, the hallmark of megaloblastic anemia.

Heart health

B12 helps break down homocysteine, an amino acid that damages blood vessels when elevated. Maintaining healthy B12 levels is one of the simplest ways to support long-term cardiovascular health.

Metabolism support

B12 plays a key role in fat and protein metabolism. It's often combined with other compounds, like Lipo-C, to amplify body composition and weight management outcomes.

The absorption problem

Most people think they're just tired. Often, they're deficient.

Studies suggest nearly 40% of adults have suboptimal B12 levels, and most don't know it. Oral supplements help, but absorption drops sharply with age and gut issues. B12 injection delivers the full dose directly into your bloodstream, bypassing every barrier between a pill and your cells. Consult your physician before starting any treatment.

  • Injection absorbs completely, no gut barrier, no waste
  • Reaches your cells within hours of administration
  • 1,000 mcg per dose, physician-selected based on your profile
  • At-home subcutaneous injection, no clinic visit required

Common questions

Everything you need to know

What is B12 and why inject it?
Vitamin B12 (cobalamin) is an essential nutrient involved in energy production, red blood cell formation, and neurological function. While oral supplements are widely available, absorption can be unreliable, especially with age or GI issues. Subcutaneous injection delivers the full dose directly into circulation, bypassing the gut entirely. Always consult your healthcare provider before starting any treatment.
How is B12 prescribed through Tides?
You complete a short online health assessment, about five minutes. A licensed physician from our network reviews your information and, if clinically appropriate, writes your prescription. No clinic visit or waiting room required.
What form does B12 come in?
B12 is prescribed as methylcobalamin, the most bioavailable form, delivered as a subcutaneous injection at 1,000mcg/ml. Your physician determines the exact dose and frequency based on your health profile and goals.
How quickly will I feel results?
Most people notice improvements in energy and mental clarity within 2 to 4 weeks. Results vary based on your baseline B12 status, those who were deficient often notice the most dramatic change. Your physician will monitor your progress throughout the protocol.
Is B12 injection safe?
B12 has an excellent safety profile. It's water-soluble, meaning excess is excreted rather than stored. Through Tides, every prescription is written by a licensed physician who reviews your health history before prescribing. Always consult your healthcare provider.
How do refills work?
Your subscription is billed monthly. Your physician reviews your protocol regularly and keeps your prescription current. You can cancel anytime before your next billing cycle.
Can I cancel my subscription?
Yes. You can cancel before your next cycle at any time. We believe in earning your trust each month, not locking you in.
Is this covered by insurance?
Most insurance plans do not cover compounded B12 injections. Tides subscriptions are priced to make physician-supervised care accessible without relying on insurance. All pricing shown is what you pay directly, with no hidden fees.
