Timed Release B12 Vitamin 1000 mcg
Spring Valley Timed Release B12 Vitamin 1000 mcg is a single vitamin and mineral supplement primarily focused on Vitamin B12. Each one-tablet serving provides a substantial 1.0mg (1000mcg) of Vitamin B12, which is considered a clinically studied dose for supporting energy metabolism and nervous system function. It also includes 25mg of Calcium, which is underdosed and likely serves as a binder rather than an active ingredient for bone health. This product has a total of 2 ingredients and maintains 100% label transparency, yet it received an N+ Score of 47, earning an 'F' grade, indicating a below-average tier. While it delivers a robust dose of B12, the limited and underdosed secondary ingredient contributes to its lower overall assessment. It may be suitable for individuals specifically seeking a high-dose Vitamin B12 supplement.
