⚡ 450 μg High-Dose Vitamin B12
Each daily drinking bottle contains:
Vitamin B12 — 450 μg / 18,000% NRV
Vitamin B12 contributes to:
Normal energy-yielding metabolism*
Reduction of tiredness and fatigue*
Normal functioning of the nervous system*
Normal psychological function*
Normal red blood cell formation*
Normal immune system function*
and has a role in the process of cell division.*
The 450 μg B12 content should be one of the main SEO terms on this product page because it clearly differentiates the product from conventional low-dose B-vitamin supplements.
🔋 B1, B6 & Niacin
Doppelherz B12 Vita-Energie also provides three selected B vitamins:
Vitamin B1 — 0.28 mg / 25% NRV
Vitamin B6 — 0.35 mg / 25% NRV
Niacin — 2.4 mg NE / 15% NRV
Vitamin B1, B6 and Niacin contribute to normal energy-yielding metabolism.*
Vitamin B6 and Niacin also contribute to the reduction of tiredness and fatigue and normal functioning of the nervous system.*
Together with high-dose B12, they create a targeted formula for everyday nutritional support.
💪 With L-Glutamine & L-Serine
Each drinking bottle additionally provides:
L-Glutamine — 45 mg
L-Serine — 40 mg
These amino acids complement the B-vitamin formula and are an important difference between Doppelherz B12 Vita-Energie and many conventional B12-only supplements.
For compliance, I would list the amino acids as formula features rather than attaching unsupported claims such as muscle building, recovery or brain performance to these quantities.
🧪 Practical 2-Phase Drinking Bottle
Doppelherz B12 Vita-Energie uses a practical nutrient-chamber bottle.
How to Prepare
1. Twist
Turn the cap clockwise beyond the clicking point to open the nutrient chamber.
2. Shake
Shake the bottle thoroughly until the nutrient powder has completely dissolved.
3. Open & Drink
Turn the cap in the opposite direction, open the bottle and drink the liquid.
This format helps differentiate the product from standard B12 tablets or capsules and is worth including in both your product description and image ALT text.
🍓 Raspberry Flavour
Doppelherz B12 Vita-Energie has a fruity raspberry flavour and can be consumed directly from the bottle after mixing.
The current product packaging also identifies the formula as vegan.
