Vaginas all have a natural odor. It's part of female physiology and shouldn't be a cause for concern. Vaginal odor can be influenced by hygiene, health, and, according to some studies, nutrition.
Some scientists believe that different products can have different effects on the microflora that cause vaginal odor.
Odor aside, getting enough protein and nutrients such as vitamins A and C , iron, and zinc is good for your vaginal immunity, helping prevent conditions such as bacterial vaginosis and yeast infections.
