Aims
The purpose of this study was to assess the evidence for an appropriate dose-response of vitamin D supplementation in patients with obesity with inadequate vitamin D serum levels.
Methods
We performed a systematic review consulting Medline, Embase and Cochrane Library up to September 2020 to identify studies that included (1) adult obese individuals with vitamin D serum levels below 75 nmol/l, (2) receiving cholecalciferol or calcidiol therapy (3) vitamin D serum levels assessment.
Results
The electronic search identified 705 potentially eligible studies, 11 of which were included and analysed. The heterogeneity of the studies did not permit a meta-analysis. Five studies (45.5%) were of high quality. Oral daily cholecalciferol resulted the route of administration that prevailed in most studies. We found that a minimum dose of =>2000UI/day might be needed to normalize 25OHD serum levels. Conversely, oral calcidiol <300IU/day failed to achieve 25OHD sufficiency.
Conclusions
Exposed evidence suggests that vitamin D requirements remain higher in patients with obesity compared to lean patients. In order to normalize 25OHD serum levels, patients taking cholecalciferol might need to triple the actual recommended vitamin D doses. In contrast, calcidiol doses are still to be clarified.
Vitamin D Life - Overview Obesity and Vitamin D contains the following summary
- FACT: People who are obese have less vitamin D in their blood
- FACT: Obese need a higher dose of vitamin D to get to the same level of vit D
- FACT: When obese people lose weight the vitamin D level in their blood increases
- FACT: Adding Calcium, perhaps in the form of fortified milk, often reduces weight
- FACT: 168 trials for vitamin D intervention of obesity as of Dec 2021
- FACT: Less weight gain by senior women with > 30 ng of vitamin D
- FACT: Dieters lost additional 5 lbs if vitamin D supplementation got them above 32 ng - RCT
- FACT: Obese lost 3X more weight by adding $10 of Vitamin D
- FACT: Those with darker skins were more likely to be obese Sept 2014
- OBSERVATION: Low Vitamin D while pregnancy ==> more obese child and adult
- OBSERVATION: Many mammals had evolved to add fat and vitamin D in the autumn
- and lose both in the Spring - unfortunately humans have forgotten to lose the fat in the Spring
- SPECULATION: Low vitamin D might be one of the causes of obesity – several studies
- SUGGESTION: Probably need more than 4,000 IU to lose weight if very low on vitamin D due to
risk factors such as overweight, age, dark skin, live far from equator,shut-in, etc. - Obesity category has

Fast weight loss by Obese Adults: Summary of the data as of Sept 2019
1) 50,000 IU Vitamin D weekly for at least 6 months
If gut problems, should use a gut-friendly form of vitamin D
2) Add calorie restriction diet and light exercise after ~2 months*
* Vitamin D levels must be above 30ng/ml to help with weight loss
* Start losing weight 2 months sooner if take a 50,000 IU daily for a week
3) More weight loss if also add Magnesium or cofactors
30% Improved Vitamin D response with Magnesium - a Vitamin D Cofactor
Note: Magnesium reduces weight loss by itself as well
20% improved vitamin D response if also add Omega-3 a Vitamin D Cofactor
Note: Omega-3 reduces weight loss by itself as well
4) More weight loss if also improve activation of Vitamin D Receptor
Vitamin D Receptor activator: 0-30% improved Vitamin D response
Obesity 1.5 X more likely if poor Vitamin D Receptor – meta-analysis Nov 2019
