How to take
Take 3 tablets once daily with food; taking with a main meal may improve absorption of fat-soluble vitamins and reduce stomach upset.
Ingredients explained
Vitamin D (cholecalciferol)
Vitamin D binds to vitamin D receptors to help regulate calcium and phosphorus balance and gene expression related to muscle function and immune activity.
Caution: Take with food for better absorption, and avoid excessive intake from multiple supplements to reduce risk of high calcium levels.
B-Complex Vitamins (Thiamin, Riboflavin, Niacin, B6, Folate, B12, Biotin, Pantothenic Acid)
B vitamins act as coenzymes in energy metabolism to help convert carbohydrates, fats, and proteins into usable cellular energy and support nervous system function.
Caution: High-potency B vitamins may cause flushing (niacin) or bright yellow urine (riboflavin), which is harmless; avoid stacking with other high-dose B supplements.
Magnesium (oxide, aspartate)
Magnesium serves as a cofactor for hundreds of enzymes involved in energy production, muscle contraction, and electrolyte balance.
Caution: May loosen stools at higher intakes; take with food to improve tolerance and separate from certain minerals if sensitive.
Zinc (zinc oxide)
Zinc participates in antioxidant defenses and supports enzyme activity involved in protein synthesis and immune function.
Caution: Can cause nausea on an empty stomach and may reduce copper absorption if taken in excess over time.
Alpha Lipoic Acid
Alpha lipoic acid functions as an antioxidant that can regenerate other antioxidants and support mitochondrial energy processes.
Caution: May lower blood sugar in some individuals; monitor how you feel if combining with other products that affect glucose.
How they work together
Core vitamins and minerals cover daily micronutrient needs related to energy metabolism, muscle function, and immune support, while alpha lipoic acid adds targeted antioxidant activity. Vitamin D and magnesium contribute to muscle and bone-related processes, and zinc supports antioxidant enzymes alongside B vitamins that drive cellular energy pathways.
Safety and tips
Label Warning: Consult a physician before use if you take any medications or are under a physician’s care for a medical condition. Intended for healthy adults. Limit to 1 serving per day and take with food.
Who should be cautious: People using anticoagulants such as warfarin due to vitamin K content may need to discuss use with a healthcare provider. Those sensitive to caffeine-like stimulants may wish to note the green tea extract. If combining with medications, consult a healthcare provider.
Storage: Store in a cool, dry place.
