Attached the EFSA report for pregnant women with all the nutrients accounted for in both products. To explain the report a little bit, the PRI value (if given) is the intake of a nutrient that is likely to meets the needs of almost all healthy people in a population. In the absence of this, the AI (adequate intake) column is based on observations or experiments, that is assumed to be adequate for the population's needs. The most important column really is the UL (upper limit) column which is the maximum nutrient intake across supplements and food that you should consume in a day.
To put both formulas side by side with the safe upper limit in mind, it looks like the below:
Nutrient | HSN | Pregnancy | UL |
Vitamin C | 40mg |
|
|
Biotin | 500μg |
|
|
Pantothenic acid | 6mg |
|
|
Zinc | 2mg |
|
|
Selenium | 200μg |
|
|
Iodine | 150μg | 150µg | 600µg |
Vitamin D3 |
| 75μg |
|
Vitamin K2 |
| 75μg |
|
Vitamin B12 |
| 50μg |
|
Folic Acid |
| 400μg |
|
Iron |
| 5mg |
|
From the above, it should be fine to take both products together but always recommend they consult their GP or midwife prior to doing so.
