Appreciate financial difficulties, but without a formal diagnosis nobody here can help you, it would not be safe or responsible for us to recommend self treating a self diagnosed issue based on several such significant symptoms. You could very easily waste a ton of money on topical products that do absolutely nothing because your issue is a hormonal or nutrient imbalance.
A healthy wholefood diet, even wheat free, can be inexpensive unless you purchase processed branded goods like pasta and bread, but there is no need for these type of foods to be in your diet. I am in the UK so it might be slightly different for you but here reasonably priced nutrient dense wholefoods include
- dried beans and lentils
- canned beans and lentils
- canned oily fish with crumbly bones (mackerel, sardines/ pilchards)
- certain fresh oily fish (sprats, herring)
- canned plain tomatoes
- frozen vegetables
- fresh longlife vegetables including squashes and root veggies
- all sorts from an ethnic/ Asian grocery store (some of the above items, large bags of dried spices, brown rice, dried soya mince, cornmeal)
- organ meats like liver
- natural peanut butter in bulk
- pumpkin seeds in bulk
Basically if it has one or two ingredients there is a good chance it is wheat free. Pricey stuff here includes most fruits and soft vegetables because they don't have a good shelf life, muscle meats, processed and deli meats (eg. bacon and ham), the more popular seafood (salmon, cod, shrimp).
What is important in nutrition is consistency, it's better to eat a basic healthy diet all the time than an optimally healthy diet half the month and rubbish the rest. Portion sizes are really important, many UK and US citizens eat far more meat than they need, a serving is only 100-125g which is very small. And certain cuts like chicken breast are shockingly low in nutrients so it's a waste of money on two counts. If you don't have good cooking facilities or a lot of spare time a cheap stick blender and cheap slow cooker/ crock pot are well worth having.
If you eat right you should not need 'vitamins', if you do want to supplement you should either focus on gaps in YOUR diet so targeted, or a complete multi vitamin and multi mineral that includes ALL the basics. Nutrients work synergistically and in opposition, randomly supplementing small groups can do more harm than good.
Common dietary deficiencies in the general population include magnesium, haem iron, bioavailable vitamin D and the long chain omega-3s DHA and EPA, any of these and others (eg. calcium, zinc, B12, folic acid) can be a problem in coeliacs or other digestive absorption issues. Oily fish and organ meats are rich in most of these nutrients, and they are foods few UK and US citizens eat enough of.
Prenatals often concentrate on B group vitamins but may be low in vitamin A, magnesium and calcium, doubling up with a B complex is likely to be unnecessary. Set an alarm on your phone to remind you to take any tablets, maybe split the bottle so you carry a few in your purse?
