My Sublingual B12 Success: No More Choking Fear!

i choke on pills sometimes which makes me scared to take them daily. this sublingual works so well for me. historically i've had very low b12, even with injections, and now with just two or three (10,000) sublinguals a week i'm up over 2000 in my blood labs. the change occurred in just three months' time and i couldn't be happier. i'm going to pare down to once a week and see how that goes with my next blood labs scheduled four months away.

i also take the vitamin d, vitamin k, and folate tabs by superior source and my endocrinologist is over the moon with how my blood labs are looking these days.

Vitamin Basics & Tips

Understanding Sublingual Vitamin B12

Sublingual tablets dissolve under your tongue, bypassing digestion for direct bloodstream absorption. This method helps people with swallowing difficulties or gut absorption issues, like our reviewer who struggled with traditional pills.

Why High-Dose B12 (10,000 mcg) Works

While the RDA for B12 is 2.4 mcg, high doses compensate for absorption problems. Only 1-2% of oral B12 gets absorbed passively. Our reviewer took 10,000 mcg sublingually 2-3x weekly, allowing sufficient uptake to correct deficiency.

Blood Lab Levels Explained

B12 levels are measured in pg/mL. Optimal ranges are 500-1300 pg/mL. The reviewer's "over 2000" result indicates sufficiency, though levels above 900 pg/mL typically resolve deficiency symptoms like fatigue or nerve issues.

Synergy with Folate, Vitamin D, and K

B12 works with folate for red blood cell production. Vitamin D enhances B12 absorption, while vitamin K regulates calcium. The reviewer's combined regimen likely amplified results – a common strategy for deficiencies.

Why Injections Sometimes Fail

B12 injections require consistent administration. Sublinguals offer daily flexibility and avoid needle discomfort. Genetic factors (MTHFR mutations) can also reduce injection efficacy, making sublinguals a viable alternative.

Maintaining Levels Long-Term

After correcting deficiency, lower maintenance doses suffice. The reviewer's plan to reduce to weekly doses aligns with medical guidance, with periodic blood tests ensuring stability.

Daily B Vitamin FAQs

Q: Can I take too much B12? A: Excess is excreted in urine, making toxicity rare. Q: Best time to take sublinguals? A: Morning on an empty stomach for optimal absorption. Q: Signs of deficiency? A: Fatigue, tingling hands/feet, memory issues. Q: Vegan sources? A: Fortified foods or supplements, as B12 is mainly animal-derived.
