Benefits of Vitamin B1: Energy and Nervous System During Pregnancy

 It plays a central role in carbohydrate metabolism and cellular energy production. The body stores it only in small amounts, making a regular intake essential. During pregnancy, thiamine requirements increase to support the heightened maternal metabolism and the development of the baby's nervous system.

In the post-partum period and during breastfeeding, it continues to contribute to energy metabolism and neurological wellbeing. The form of thiamine and its bioavailability directly influence the effectiveness of the intake.

Vitamin B1 in the diet

Vitamin B1 is found naturally in wholegrains, brown rice, legumes such as lentils and chickpeas, sunflower seeds, pork, nuts and nutritional yeast. The absorption of thiamine depends on the cooking method, as it is sensitive to heat and water: prolonged cooking or excessive soaking can significantly reduce its content. Intakes from refined cereals are often low, as the refining process removes a large proportion of the vitamin B1 present in the grain's outer layer. People experiencing pregnancy nausea or following a restricted diet may see their intake decrease.

Vitamin B1 as a supplement

In food supplement form, vitamin B1 is available as thiamine hydrochloride, thiamine mononitrate or benfotiamine, a fat-soluble form with greater bioavailability. It is generally found in B-complex vitamins or prenatal multivitamins. The pregnancy food supplements Jolly Mama supplements incorporate thiamine into balanced formulas, alongside other B-group vitamins that work in synergy. A quality supplement ensures precise dosing and good vitamin stability. Vegan-friendly formulas are suitable for vegetarian and vegan diets, and thiamine is generally very well tolerated digestively.
