11. Vitamin B supplements
B vitamins are required to stimulate hunger and food consumption, resulting in increased weight.
They help with metabolism, including energy generation and nutrient utilization.
12. Vitamin D supplements
Vitamin D might help you gain weight. Vitamin D absorption improves bone mass. Several studies have demonstrated that vitamin D plays an important role in weight control and overall health.
This vitamin boosts the body’s ability to absorb calcium, which raises bone weight and leads to weight gain, particularly lean body mass.
