With nutraMetrix isotonic powdered formulas you can make up your own blends.
This is what I do....I use a glass jar is air tight with a rubber seal. You must be careful to keep the powder in a tightly sealed container to prevent moisture from getting in.
The above photo is a blend of the Isotonic Greens, OPC-3, Activated B Complex, Vitamin D w/ K2. Serving size is 1 tablespoon with 6 ounces of water. This jar will last us about 3 months.
You can make a blend of which ever formulas you prefer.
If you want exact serving proportions then leave them in the individual bottles they come in and measure each one out individually. Another option is to have nutraMetrix make up a custom blend for you.
We like the nutraMetrix isotonic formulas because we don't like swallowing a hand full of tablets or capsules.
