Myo-Inositol and NAC: An Ingredient Guide

Key takeaways - Myo-inositol is a vitamin-like compound found in foods and made in small amounts by the body. - NAC is a stable form of the amino acid cysteine. - Inobalance Pro+ serving (2 capsules): 500mg myo-inositol and 100mg NAC, in a 9-in-1 formula. - Our stand-alone NAC has 400mg NAC with 50mg alpha lipoic acid per capsule.

Myo-inositol and NAC often appear on the same label. This guide explains what each one is and shows exactly how much of each is in our products, so you can compare labels with confidence.

What is myo-inositol?

Myo-inositol is a natural, vitamin-like compound. Foods such as fruits, beans, grains and nuts contain it, and your body makes small amounts too. It is not a hormone. In cells, it takes part in how cells pass along signals, which is why it appears in nutrition research and daily supplements.

What is NAC?

NAC stands for N-Acetyl Cysteine. It is a stable form of the amino acid cysteine. In supplements it is used as an ingredient for daily nutritional support. Because NAC has its own cautions, read the label amount and compare products by milligrams.

Inside Inobalance Pro+

Inobalance Pro+ is a 9-in-1 formula. A serving is 2 capsules, delivering 922mg of active ingredients:

Ingredient Per serving
Myo-Inositol 500mg
N-Acetyl Cysteine (NAC) 100mg
Coenzyme Q10 (ubidecarenone) 60mg
Shatavari extract (listed as Asparagus densiflorus) 200mg
Alpha Lipoic Acid 50mg
Folate (L-methylfolate) 176.47mcg, 100% of the daily value shown
Zinc (zinc gluconate) 10mg, 59%
Vitamin B6 (pyridoxine hydrochloride) 2mg, 83%
Vitamin D3 (cholecalciferol) 400IU, 100%

Each bottle has 90 vegetarian (HPMC) capsules, which is 45 servings, or a 45-day supply at 2 capsules a day. The capsules also contain a stabilizer (INS 460) and an anticaking agent (INS 551). The bottle is amber glass.

How the stand-alone NAC compares

Our NAC 400mg with Alpha Lipoic Acid has 400mg NAC and 50mg alpha lipoic acid in each capsule, 450mg in all. A serving is 1 capsule, and a bottle of 90 vegetarian capsules is a 90-day supply. It is free from sugar, gluten and GMOs.

So the two products differ clearly: Inobalance Pro+ has 100mg NAC per serving as one of nine ingredients, while the NAC capsule has 400mg NAC as its lead ingredient. Choose by reading the label, not by name.

How to read this kind of label

  1. Serving size. Inobalance Pro+ is 2 capsules, so each amount above is for two.
  2. The 922mg figure. This is the total of the active ingredients, not any one of them.
  3. Percent daily value. Folate, zinc, B6 and D3 are shown as percentages. If you also take a multivitamin, add them up to avoid doubling up.
  4. Herbal extracts. Shatavari is an herb. Ask your provider if you take herbal products.
  5. Other ingredients. Check capsule material and added ingredients.

Tips for taking them

  • Follow the directions on the bottle.
  • Pick a regular time so it is easy to remember.
  • Do not raise the amount on your own.
  • Store in a cool, dry, dark place, out of reach of children.
  • Tell every provider you see which supplements you use.

Talk to your healthcare provider

Talk to your healthcare provider, especially if you are pregnant, nursing, take medication or have a medical condition. Ask first if you are planning surgery, or if you take blood thinners or other prescription medicines, since some ingredients may interact with medicines. These products are for adults. Supplements are not a substitute for medical care, and you should never stop or change a medicine because of a supplement. Stop use and call your provider if you have an unusual reaction.
