Younger patients like you may not need really high doses of supplements yet. As we age, use of supplements atrophies and that is when they work best.

Also insulin resistance and diabetes is higher in Native Americans and Mexican patients.(in the US).
You can have insulin resistance if you are young, it is becoming more common (but I see that more often in African Americans).
Insulin resistance and sometimes diabetes comes with PCOS in females.

1.- Vit b12 --if you are low in this and are shown by testing, then starting at 1mg (1000mcg) daily is a good start. If you do not have testing you can still try it, and if after several months you see no improvement you can assume you don't need it.

2.- Vit b6--this works with B12, and maximum doses should not go over 50mg/day for most people.

3.- Folic acid--800mcg is typical dose. Works well with B6 and B12. US foods are fortified now with folic acid, but I don't know what you have in Mexico

4.- Benfothiamine--this is improved thiamine B1, helpful for people who drink alcohol or have problems with certain enzyme actions , the dehydrogenases. 150mg-300mg per day

5.- Lipoic acid--evidence for thyroid effects is not clear or definite. Use the new R-lipoic in lower doses 50 to 100mg per day instead of the high alpha doses.

6.- Folic acid (duplicate)

7.- Fish oil--typically 1 to 3 caps of regular fish oil are usually enough for most people

8.- Magnesium--typically 200mg of elemental a day to supplement what you eat to give the 380-400mg elemental RDA

9.- D chiro inositol (mainly for my problem wih PCOS)--follow the directions on the bottle of the new product you purchased. A 60ct bottle suggests 2 a day. You can start at one a day and see if you get results to save $$. Chiro is new, more potent than myo-inositol and should not need really high doses.

10.- Calcium--If you don't eat any foods with calcium higher doses are needed. Range is 500mg-1500 a day.

11.- A bit of vit. D (which is included in the calcium supplement)--the amount in a mixture of calcium is usually low. New recommendations are for up to 2000 IU/day. The more D you take the less calcium you need because it enhances calcium absorption. Supplements sold separately of D3 allow for dose changes. You can be tested for this so you will know exactly what you need.

12. Zinc-- zinc and selenium are needed for proper thyroid functions. Vegetarians need more than others. Signs of low zinc are acne and increased infections. 30mg of OptiZinc works well for most people who may be low in this mineral. Your lifestyle dictates your need for this. You can be tested for this, to see if you are low.

13. Selenium-- same with this. Do not go over 100mcg/day, as high doses of selenium are showing a connection to diabetes in some people. Selenium and zinc are basically for people with lifestyle dietary issues. They are less critical for neuropathy.
