This vitamin B boosted my daily energy, though the messy dropper needs redesign for precise dosing.
The vitamin B complex effectively increased my daily vitality and focus, but impractical dropper design and inconsistent flavor in newer batches impacted long-term usability and trust in product quality.
This is a review of product:
Why Not Natural Organic Vitamin B12 Liquid - Sublingual Extra Strength 60 x 5000 mcg Methylcobalamin Drops, Vegan, Maximize Absorption and Energy
From Amazon.com
I’m pretty sure I’m feeling energy every day from taking this. My only complaint is the dropper. It is pretty much impossible to read and you have to squirt very slowly to avoid the liquid going all over the place. If that were improved, I would give it five stars.
UPDATE: I’ve cancelled my auto delivery. The first two bottles tasted fine. The last two have an off taste that gives me concerns about product quality.
Vitamin Basics & Tips
Understanding Vitamin B Complex Benefits
Vitamin B complex refers to eight water-soluble vitamins essential for energy production, brain function, and cell metabolism. Users report increased energy from enhanced conversion of food into ATP (adenosine triphosphate), the body's primary energy currency.
Dropper Design Challenges
The mentioned dropper issues relate to two common problems: legibility markers and viscosity control. Quality droppers should use embossed measurements and controlled aperture sizes to manage thick liquids without dripping.
Taste Consistency in Supplements
Flavor variations in liquid supplements often indicate formulation changes, oxidation, or storage issues. B vitamins naturally have bitter notes, requiring careful masking through ingredients like stevia or citrus extracts.
Liquid vs Tablet Absorption
Liquid supplements boast higher bioavailability through sublingual absorption, bypassing digestive breakdown. Studies show liquid B vitamins can achieve 98% absorption vs 70-80% in tablets.
Quality Control Red Flags
Batch inconsistencies (like taste changes) may suggest manufacturing process alterations, raw material sourcing issues, or improper storage conditions affecting product stability.
Daily B Vitamin Requirements
Adults need:- B1 (1.1-1.2mg)- B2 (1.1-1.3mg)- B3 (14-16mg NE)- B5 (5mg)- B6 (1.3-1.7mg)- B7 (30mcg)- B9 (400mcg DFE)- B12 (2.4mcg)Excess amounts are typically excreted in urine.
Common Vitamin B Deficiency Signs
Fatigue, brain fog, mouth ulcers, and tingling extremities often indicate B vitamin deficiencies. Vegetarians and seniors are particularly prone to B12 deficiency.
