The vitamin E derived from soy does not contain soy proteins and therefore does not need to be listed as an allergen according to the law. Those allergic to soy protein can safely use a vitamin E supplement or multivitamin.

In many supplements, vitamin E is dissolved in soybean oil. With fully refined soybean oil, there is no risk of an allergic reaction. Such oil also does not need to be listed as an allergen on the packaging.

However, there are also vitamin E supplements that do not contain soybean oil. If you want to be on the safe side, you can choose one of those variants.

A good alternative to this formula from Orthica is, for example, the Vitamin E 268 mg/400 IU Complex from Solgar, where the vitamin E is dissolved in safflower oil. The product contains no dairy, gluten, or nuts.

Prena Fem already contains fish oil (48 mg EPA and 200 mg DHA per daily dosage of 2 capsules), so there is no need to take an additional fish oil product. Prena Fem also contains a generous amount of vitamin E: 164 mg.

While vitamin E is important for fertility, and a deficiency in this vitamin can lead to infertility, it is not the case that more vitamin E will result in higher fertility. If you have been using Prena Fem for some time, it is unlikely that you have a deficiency in this vitamin. Therefore, taking extra vitamin E is not necessary. However, it is permissible. You can combine Prena Fem with Vitamin E 200.

Additionally, it is advisable to moderate alcohol and caffeine intake, and preferably not to smoke. Regularly determine your fertile period with a fertility test (such as the Ovulation Test (cassette)).

Your partner can use B Daddy, and it is better for him not to take warm baths too often, as high temperatures can adversely affect fertility.
