Trial was only 6 weeks – hardly enough time to get to a good level of vitamin D
Longer trial or starting with loading dose would have had much better results

Overview Loading of vitamin D contains the following
If a person is, or is suspected to be, very vitamin D deficient a loading dose is typically given
- Loading = repletion = quick replacement (previously known as Stoss)
- Loading doses range in size from 100,000 IU to 1,000,000 IU of Vitamin D3
- The size of the loading dose is a function of body weight - see below
Unfortunately, some doctors persist in using Vitamin D2 instead of D3 - Loading may be done as quickly as a single day, to as slowly as 3 months.
It appears that spreading the loading dose over 4-20 days is a good compromise - Loading is typically oral, but sometimes by injection (I.M,)
- The loading dose persists in the body for about 3 months
The loading dose should be followed up with continuing maintenance
Unfortunately, many doctors fail to follow-up with the maintenance dosing. - As about 1 in 300 people have some form of mild allergic reaction to vitamin D supplements,
it appears prudent to test with a small amount of vitamin D before giving a loading dose - The causes of a mild allergic reaction appear to be: (in order of occurance)
1) lack of magnesium - which can be easily added
2) allergy to capsule contents - oil, additives (powder does not appear to cause any reaction)
3) allergy to the tiny amount of D3 itself (allergy to wool) ( alternate: D3 made from plants )
Objective
This study was performed to evaluate the effects of vitamin D and omega-3 fatty acids co- supplementation on glucose metabolism and lipid concentrations in gestational diabetes (GDM) patients.
Methods
This randomized double-blind placebo-controlled clinical trial was done among 140 GDM patients. Participants were randomly divided into four groups to receive:
- 1) 1000 mg omega-3 fatty acids containing 360 mg eicosapentaenoic acid (EPA) and 240 mg docosahexaenoic acid (DHA) twice a day+ vitamin D placebo (n=35);
- 2) 50,000 IU vitamin D every 2 weeks+ omega-3 fatty acids placebo (n=35);
- 3) 50,000 IU vitamin D every 2 weeks+1000 mg omega-3 fatty acids twice a day (n=35) and
- 4) vitamin D placebo+omega-3 fatty acids placebo (n=35) for 6 weeks.
Results
After 6 weeks of intervention, patients who received combined vitamin D and omega-3 fatty acids supplements compared with vitamin D, omega-3 fatty acids and placebo had significantly decreased
- fasting plasma glucose (FPG) (-7.3±7.8, -6.9±6.6, -4.0±2.5 and +1.0±11.4 mg/dL, respectively, P<0.001),
- serum insulin levels (-1.9±1.9, -1.3±6.3, -0.4±6.3 and +2.6±6.5 μIU/mL, respectively, P=0.005),
- homeostatic model of assessment for insulin resistance (HOMA-IR) (-0.7±0.6, -0.5±1.4, -0.2±1.5 and +0.6±1.5, respectively, P<0.001)
- increased quantitative insulin sensitivity check index (QUICKI) (+0.01±0.01, +0.008±0.02, +0.002±0.02 and -0.005±0.02, respectively, P=0.001). In addition, changes in
- serum triglycerides (-8.2±41.0, +7.6±31.5, +3.6±29.9 and +20.1±29.6 mg/dL, respectively, P=0.006) and
- VLDL-cholesterol (-1.6±8.2, +1.5±6.3, +0.8±6.0 and +4.0±5.9 mg/dL, respectively, P=0.006) in the vitamin D plus omega-3 fatty acids group were significantly different from the changes in these indicators in the vitamin D, omega-3 fatty acids and placebo groups.
Conclusion
Overall, vitamin D and omega-3 fatty acids co-supplementation for 6 weeks among GDM patients had beneficial effects on FPG, serum insulin levels, HOMA-IR, QUICKI, serum triglycerides and VLDL-cholesterol levels.

Nice outcome trends for this short small study
Anticipate that a long study with more mothers would get many statistically significant results
Background
This study was carried out to determine the effects of vitamin D and omega-3 fatty acids co- supplementation on biomarkers of inflammation, oxidative stress and pregnancy outcomes in gestational diabetes (GDM) patients.
METHODS:
This randomized, double-blind, placebo-controlled trial was conducted among 120 GDM women.
Participants were randomly divided into four groups to receive:
- 1) 1000 mg omega-3 fatty acids containing 180 mg eicosapentaenoic acid (EPA) and 120 mg docosahexaenoic acid (DHA) twice a day + vitamin D placebo (n = 30);
- 2) 50,000 IU vitamin D every 2 weeks + omega-3 fatty acids placebo (n = 30);
- 3) 50,000 IU vitamin D every 2 weeks + 1000 mg omega-3 fatty acids twice a day (n = 30) and
- 4) vitamin D placebo + omega-3 fatty acids placebo (n = 30) for 6 weeks.
Results
Subjects who received vitamin D plus omega-3 fatty acids supplements compared with vitamin D, omega-3 fatty acids and placebo had significantly decreased high-sensitivity C-reactive protein (−2.0 ± 3.3 vs. -0.8 ± 4.4, −1.3 ± 2.4 and +0.9 ± 2.7 mg/L, respectively, P = 0.008), malondialdehyde (−0.5 ± 0.5 vs. −0.2 ± 0.5, −0.3 ± 0.9 and +0.5 ± 1.4 μmol/L, respectively, P < 0.001), and increased total antioxidant capacity (+92.1 ± 70.1 vs. +55.1 ± 123.6, +88.4 ± 95.2 and +1.0 ± 90.8 mmol/L, respectively, P = 0.001) and glutathione (+95.7 ± 86.7 vs. +23.0 ± 62.3, +30.0 ± 66.5 and −7.8 ± 126.5 μmol/L, respectively, P = 0.001). In addition, vitamin D and omega-3 fatty acids co-supplementation, compared with vitamin D, omega-3 fatty acids and placebo, resulted in lower incidences of newborns’ hyperbilirubinemiain (P = 0.037) and newborns’ hospitalization (P = 0.037).
Conclusion
Overall, vitamin D and omega-3 fatty acids co-supplementation for 6 weeks among GDM women had beneficial effects on some biomarkers of inflammation, oxidative stress and pregnancy outcomes.
