Vitamin D + Zinc
B!TONIC® Vitamin D + Zinc is a targeted daily supplement combining 2000 IU (50 µg) plant-based vitamin D3 with 15 mg highly bioavailable zinc to support immune strength, bone density, and cellular protection. This essential duo helps maintain healthy immune function, muscle activity, and mineral absorption — especially valuable during low sun exposure, seasonal transitions, or nutritional imbalance.
Formulated to support multiple systems, this precise combination promotes calcium homeostasis, healthy cell division, and antioxidant defense.
Developed by experts in Austria and Germany to pharmaceutical standards.
Free from gluten, lactose, gelatin, added sugars, colorants, and allergens. 100% vegetarian.
Description
A clean, high-potency pairing of vitamin D3 (cholecalciferol, plant-based) and zinc (as zinc gluconate) to reinforce immune readiness, support bones and muscles, and protect cells from oxidative stress. Ideal for times of limited sunlight, increased demands on the immune system, or confirmed micronutrient gaps.
Ingredients
-
Vitamin D3 (plant-based cholecalciferol) *PREMIUM — contributes to:
- normal immune system function
- calcium and phosphorus absorption and utilization
- maintenance of healthy bones, teeth, and muscle function
- normal blood calcium levels
-
Zinc (as zinc gluconate) *PREMIUM — supports:
- enzyme activation and antioxidant defense
- normal cell division and protein synthesis
- cognitive function and healthy skin, hair, nails, and vision
- acid-base balance and metabolism of macronutrients, fats, and carbohydrates
Formulated for bioavailability and purity.
How to take
Take 1 capsule daily, preferably with a main meal.
Recommended for short-term use (up to one month). For longer-term intake, seek professional guidance.
Recommended for
- Individuals with weakened immune defenses or frequent infections
- People with limited sun exposure, sedentary lifestyle, or aging bones
- Those with confirmed vitamin D or zinc deficiencies
- Support during periods of fatigue, oxidative stress, or convalescence
- Ideal for nutrient-depleted diets or foundational immune support
Bio-Precision Optimization
- For best absorption, take after a meal containing healthy fats (e.g., olive oil, avocado, nuts).
- This enhances lipid-based uptake of vitamin D and complements zinc’s enzyme-activating role, supporting immune response and mineral homeostasis during peak metabolic times.

Benefits of daily usage
Bio-Precision Support
Benefits of Daily Usage – Stable Nutrient Status
Consistent, daily usage helps maintain optimal micronutrient levels so key enzymes can work reliably. Over weeks, this supports steady energy, focus, immune balance, and visible wellness (e.g., skin, hair, nails).
Bio-Precision Support – Active, Body-Aligned Forms
Btonic uses bio-identical or activated vitamin forms and clean co-factors to target real physiological pathways (energy metabolism, nervous system balance, antioxidant defense) with high usability and minimal waste.
Clinically-Calibrated & Clean – Made to Tolerate Daily
Evidence-informed doses, EU-GMP manufacturing, and minimal additives mean the formulas are effective, consistent, and gentle enough for everyday routines—so you can actually stick with them and see cumulative benefits.
BIO-PRECISION HACK
