官方页面如何描述
官方产品页将其描述为每日两片的综合维生素，含有维生素、矿物质和植物提取物。本页只整理标签相关资料，不把制造商的描述当成医疗建议。
下一步要核对什么
实际配方、食用方式和各成分含量应以最新官方标签和产品页为准。营养研究应另外对照独立资料来源。
配方可能如何运作
此配方将多种维生素和矿物质辅因子组合，用于支持正常能量代谢、神经系统、免疫生理、骨骼／矿物质调节和抗氧化系统。整体机制是营养支持，不是疾病治疗途径；额外植物成分和类胡萝卜素的证据较不一致。
有效成分
成分名称和含量按照官方来源披露的资料；没有披露的数值不会自行推算。
成分每份含量作用／机制说明
Vitamin A (beta-carotene, acetate)1,500 mcg RAE / 5,000 IUVision, epithelial tissue and immune-function support; excess preformed vitamin A has different risks from beta-carotene.
Vitamin C (ascorbic acid, calcium and niacinamide ascorbates)470 mgCollagen synthesis and antioxidant chemistry; high supplemental amounts can cause gastrointestinal upset in some people.
Vitamin D3 (cholecalciferol)50 mcg / 2,000 IURegulates calcium and phosphate signalling and supports bone and immune functions.
Vitamin E (D-alpha tocopheryl succinate, D-alpha tocopherol)67 mgLipid-soluble antioxidant activity; high supplemental intake may matter with anticoagulant use.
Thiamine (vitamin B1)75 mgCofactor in carbohydrate and cellular energy metabolism.
Riboflavin (vitamin B2)50 mgCofactor for redox reactions and energy metabolism.
Niacin (niacinamide, niacinamide ascorbate)50 mg NENAD/NADP precursor for energy metabolism and cellular redox reactions.
Vitamin B6 (pyridoxine HCl, pyridoxal 5'-phosphate)75 mgCofactor in amino-acid metabolism and neurotransmitter synthesis; long-term high intake deserves review.
Folate (L-5-methyltetrahydrofolate calcium salt)680 mcg DFEOne-carbon metabolism, DNA synthesis and red-blood-cell formation.
Vitamin B12 (methylcobalamin)300 mcgCofactor for neurological function and red-blood-cell formation.
Biotin300 mcgCofactor for fatty-acid, glucose and amino-acid metabolism; can interfere with some lab tests.
Pantothenic acid50 mgPrecursor of coenzyme A, central to energy and fatty-acid metabolism.
Iodine (potassium iodide)150 mcgSubstrate for thyroid-hormone synthesis; excess can disturb thyroid function in susceptible people.
Magnesium (magnesium oxide)100 mgMineral cofactor in enzyme reactions, nerve and muscle function.
Zinc (zinc citrate, L-OptiZinc)25 mgCofactor for enzymes, immune signalling and DNA/protein synthesis.
Selenium (three forms)200 mcgSupports selenoproteins involved in antioxidant defence and thyroid metabolism; excess can be toxic.
Manganese (citrate, gluconate)2 mgCofactor for connective-tissue, bone and antioxidant enzymes.
Chromium (Crominex 3+ complex)200 mcgMay influence insulin signalling and glucose metabolism; evidence for supplementation varies.
Molybdenum100 mcgTrace-element cofactor for several oxidation enzymes.
Inositol50 mgParticipates in cell-membrane signalling; product-specific benefit is not established by this profile.
Alpha-lipoic acid25 mgRedox cofactor involved in mitochondrial energy metabolism; evidence depends on the use case.
Natural mixed tocopherols20 mgAdditional vitamin E-family antioxidant compounds.
Bio-Quercetin proprietary blend14 mg providing 5 mg quercetinFlavonoid blend with antioxidant and cell-signalling research; product-specific outcomes remain uncertain.
Marigold extract (lutein and zeaxanthin)11.12 mg providing 5 mg lutein and 155 mcg zeaxanthinCarotenoids concentrated in the eye; support for normal visual-system biology.
Apigenin5 mgPlant flavonoid with laboratory and early human research; no guaranteed clinical outcome.
Boron3 mgTrace element involved in mineral and bone biology; optimal supplemental use is not established for everyone.
Lycopene1 mgCarotenoid with antioxidant research; product-specific health effects remain uncertain.
