The Claim
In middle-aged women aged 45–63 with suboptimal micronutrient intake, 12 weeks of daily supplementation with vitamin D3 (5000 IU), vitamin K2 (100 μg), vitamin B6 (2.5 mg), vitamin B12 (1000 μg), and magnesium (75 mg) is associated with a 1.4 kg reduction in body weight, a 1.2% reduction in body fat percentage, and a 1.5 cm reduction in waist circumference, without loss of lean mass.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Among middle-aged women with low micronutrient levels, taking a daily supplement of vitamin D3, vitamin K2, vitamin B6, vitamin B12, and magnesium for 12 weeks is linked to a 1.4 kg decrease in body weight, a 1.2% drop in body fat percentage, and a 1.5 cm reduction in waist circumference, with no change in lean mass.
See the scientific wording
In middle-aged women aged 45–63 with suboptimal micronutrient intake, 12 weeks of daily supplementation with vitamin D3 (5000 IU), vitamin K2 (100 μg), vitamin B6 (2.5 mg), vitamin B12 (1000 μg), and magnesium (75 mg) is associated with a 1.4 kg reduction in body weight, a 1.2% reduction in body fat percentage, and a 1.5 cm reduction in waist circumference, without loss of lean mass, suggesting a potential link to favorable body composition changes.
Vitamins B6 and B12, with help from magnesium, lower a blood compound called homocysteine, which allows the body to burn fat more efficiently for energy. Magnesium also helps insulin work better, so muscles take up more sugar from the blood instead of storing it as fat. This shifts the body’s energy use toward burning fat, especially around the waist, without breaking down muscle. Vitamin D3 and K2 support this by keeping blood vessels healthy and reducing harmful fat buildup in arteries.
What the research says
1 studyThis study found that middle-aged women who took a daily mix of these vitamins and magnesium for 12 weeks lost a little weight and body fat, especially around the waist, without losing muscle — just like the claim says.
