The popularity of the keto diet for weight loss is also making MCTs a go-to ingredient. In 2019, 16% of North American keto product launches contained MCTs, up from 11% four years before.2 Cayenne pepper (which contains the bioactive capsaicin) is a newer weight management ingredient emerging in the market,3 showing up in weight loss supplements such as Skinny Gal Thermogenic.
Iron is also found in nutrition products targeting women. Women’s iron needs tend to be higher than men’s—plus there’s a high awareness of the link between iron deficiency and anemia, which can lead to low energy levels. Iron is also highly associated with immune system support by consumers globally (by 70% of consumers).4 Like iron, vitamin B12 is another nutrient that’s essential for red blood cell production and preventing anemia.
Key Ingredient Benefits for the Body
Iron is an essential mineral used to make hemoglobin (a protein in red blood cells) and myoglobin (a protein in muscle cells), which are responsible for transporting oxygen. Since women lose iron through menstruation, iron deficiency is more common in women than men. Iron deficiency during pregnancy can increase the risk of perinatal mortality, prematurity, and low birth weight.
While iron is also necessary for growth, development, and making certain hormones, its role in transporting oxygen is especially significant for active women. Low iron means low energy levels, including weakness and tiredness. Women engaged in strenuous physical activity can also lose iron through hemolysis and sweating.
2. Vitamin B12
Vitamin B12 is an essential vitamin also required in the formation of red blood cells. As with iron, a vitamin B12 deficiency can cause symptoms related to low red blood cell count and insufficient oxygen such as fatigue and shortness of breath. Since vitamin B12 must be obtained through the diet, those on a vegan diet are at special risk of deficiency.
The impact of vitamin B12 on the body’s energy levels in itself makes it a key nutrient for active women. However, the roles of this vitamin are many. Vitamin B12 is involved in the transmission of nerve signals and the synthesis of DNA, for example, making it essential to the function of all the body’s systems.
