From the Guidelines
Vitamin S-15.6 is not a recognized vitamin in nutritional science, and therefore, there is no established recommended dietary allowance or tolerable upper intake level for it. The standard vitamins include A, B complex (B1, B2, B3, B5, B6, B7, B9, B12), C, D, E, and K, as outlined in the evidence-based nutrition principles and recommendations for the treatment and prevention of diabetes and related complications 1. The designation "S-15.6" does not correspond to any established vitamin in human nutrition.
If you're looking for information about a specific vitamin supplement or compound, it may be marketed under a proprietary name or could be referring to a different type of nutrient or supplement altogether. Without additional context, I cannot provide specific dosage recommendations or regimens for something called Vitamin S-15.6.
- Key points to consider:
- The Institute of Medicine Food and Nutrition Board provides guidelines on Recommended Dietary Allowance (RDA), Adequate Intake (AI), and Tolerable Upper Intake Level (UL) for established vitamins and minerals 1.
- Evaluation of micronutrient status should begin with a careful clinical history and may include laboratory evaluations, but the evidence does not support the use of "Vitamin S-15.6" in this context.
- Antioxidants and vitamins, when taken in megadoses, have not been demonstrated to protect against cardiovascular disease, diabetes, or various forms of cancer, and may lead to health problems 1. It's best to consult with a healthcare provider who can evaluate your specific nutritional needs and provide appropriate guidance based on established nutritional science.
From the Research
Vitamin D Overview
- Vitamin D is a fat-soluble vitamin that plays a crucial role in maintaining a healthy mineralized skeleton and has immunomodulatory effects 2.
- It has been associated with a variety of common disorders, including musculoskeletal, metabolic, cardiovascular, malignant, autoimmune, and infectious diseases 3.
Health Benefits of Vitamin D
- Vitamin D supplementation can prevent and cure nutritional rickets in infants and children 4.
- It may reduce the risk of respiratory tract infections in children and adolescents 3.
- Vitamin D supplementation may be helpful in patients with major depression, and high-dose vitamin D may improve pain in people with fibromyalgia 5.
- Supplementing patients with prediabetes reduced the risk of progression to type 2 diabetes mellitus 5.
Optimal Vitamin D Levels
- The optimal level of serum 25-hydroxyvitamin D is still debatable, but it is advisable to maintain serum 25-hydroxyvitamin D at least 30 ng/mL (75 nmol/L), and preferably at 40-60 ng/mL (100-150 nmol/L) to achieve the optimal overall health benefits of vitamin D 2.
- Serum concentrations > 30 ng/mL (75 nmol/L) significantly lower disease and mortality risks compared to <20 ng/mL 6.
Recommendations for Vitamin D Supplementation
- The panel suggests empiric vitamin D supplementation for children and adolescents aged 1 to 18 years, those aged 75 years and older, pregnant individuals, and those with high-risk prediabetes 3.
- Daily supplementation with 2000 IU/day (50 mcg/day) of vitamin D3 can prevent diseases and deaths, and a daily dose between 4000 and 6000 IU of vitamin D3 may provide greater protection against many adverse health outcomes 6.
