Modern female sexual dysfunction is caused by hidden malnutrition. In particular, omega-3 fatty acid deficiency causes a drop in libido in women. Eating a diet with at least 1700 mg of EPA and 1300 mg of DHA for a woman over 130 pounds will improve sexual function. Also take the RDA of calcium/magnesium/zinc, a good multivitamin, avoid stimulants like caffeine, try to eat a 40/30/30 diet, avoid transfats and polyunsaturated vegetables oils like corn oil and soybean oil, and avoid tofu and soy products. Saturated fats like butter and fatty meat are fine, and so are monounsaturated vegetable oils like olive oil. Exercise the PC muscles with a resistance device like Gyneflex or the Kegelmaster.
Check with your doctor before taking high dose fish oil like this, particularly about drug interactions. Try to get a brand with at least EPA + DHA > 500 mg per one one-gram capsule. Take with food. Take a couple weeks to get up to the full dosage. Do not take high-dose fish oil if you are on any blood-thinning medication like Coumadin, take lots of over-the-counter pain relievers, take aspirin therapy, have a defibrillator, are scheduled for surgery, or are allergic to seafood.
This diet will work after about a month at the full dosage. A 230-pound woman should double the fish oil dosage. A 180-pound woman should take 1.5 times the dosage, etc.
The diet works better for women not on antidepressants or hormonal birth control.
