Nature's Bounty Vitamin B-12 1,000 mcg is a single-ingredient B-12 supplement formulated with cyanocobalamin and sold as 200 tablets per bottle. The label positions the product for people aiming to support cellular energy conversion and cardiovascular, circulatory and nervous system health via a daily 1-tablet regimen. Each tablet supplies 1,000 mcg of B-12, listed on the label as 16,667% of the Daily Value.
This review draws on Nature's Bounty product labeling and ingredient list (tablet format, serving size, and full supplement facts), retailer listings and aggregated review pages referenced in the research brief, plus the brand's stated warnings and 'no' allergen claims. I focus only on facts present in those sources: dose, form (cyanocobalamin tablets), ingredient entries, allergen declarations and the product's labeled directions.
High-level verdict: If you want a high-potency, clearly labeled B-12 tablet with 200 servings and an allergen-minimized formula, this is a practical choice — strengths are the 1,000 mcg dose, 200-tablet supply and a long list of ‘No’ allergen claims. Downsides include the use of cyanocobalamin (the form specified on the label), the tablet format rather than a sublingual/lozenge delivery, and a very high percent Daily Value that makes medical guidance advisable for some users.
How strong is the dose and what does the label say?
Each serving is one tablet containing 1,000 mcg (micrograms) of Vitamin B-12 as cyanocobalamin; the Supplement Facts on the label lists that amount as 16,667% of the Daily Value. The bottle contains 200 tablets, giving 200 days of supply at the label's recommended one-tablet-per-day serving.
The label frames the dose for supporting conversion of food into cellular energy and cardiovascular, circulatory and nervous system health. The numeric potency and serving count are explicit on the product page and packaging information used for this review.
What is the B-12 form and what else is in the tablet?
The product uses cyanocobalamin as the Vitamin B-12 form and is marketed on the label as suitable for vegetarians. Other listed ingredients include dicalcium phosphate, vegetable cellulose and vegetable stearic acid, with <2% of Natural Palm Leaf Glaze, silica and vegetable magnesium stearate.
The label also highlights a long list of exclusions: Non-GMO, No Artificial Color, No Artificial Flavor, No Sugar, No Starch, No Milk, No Lactose, No Soy, No Gluten, No Wheat, No Yeast and No Fish; it is also listed as sodium free.
Label warnings and recommended precautions
The product label includes the standard warning to consult a doctor if pregnant, nursing, taking any medications, or having any medical condition, and to discontinue use and consult a doctor if adverse reactions occur. Keep out of reach of children and do not use if the seal under the cap is broken or missing.
Because each tablet supplies 1,000 mcg (16,667% DV), the label’s warning to consult a healthcare professional before use is prominent and consistent with the high-dose nature of the supplement.
How easy is it to take and how long does a bottle last?
Directions on the label are one (1) tablet daily, preferably with a meal. With 200 tablets per bottle, following label directions provides 200 days of supply from a single container.
The tablet delivery and once-daily dosing make it simple for routine use; however, the product is presented as tablets (not explicitly as sublingual lozenges) on the official product information used here, so consumers seeking a lozenge or sublingual format should confirm the product form before purchase.
What health claims does the label make and how are they presented?
The label states that Vitamin B-12 aids in the conversion of food into cellular energy and contributes to cardiovascular, circulatory and nervous system health. These claims are presented as supporting statements on the product page and Supplement Facts label.
The product page includes an FAQ snippet advising that users follow the label directions and consult a doctor for questions about taking more than the recommended dose; the review relies solely on that stated guidance and labeling rather than external efficacy studies.

Who Should Buy This & Who Should Skip It
Buy it if: Buy this if you want a clearly labeled, high‑potency 1,000 mcg B-12 tablet with 200 days of supply and a long list of 'no' allergen claims. It's suitable for vegetarians who prefer cyanocobalamin in a once-daily tablet format and who will consult medical advice if they have pregnancy, nursing or medication concerns.
Skip it if: Skip this product if you require a sublingual/lozenge delivery method or specifically want a form other than cyanocobalamin (e.g., methylcobalamin). Also skip or consult a clinician first if you are pregnant, nursing, on medications, or have a condition where a very high percent Daily Value would be inappropriate.
