Abstract

A composition for administration to a subject, such as oral administration to a subject, for example, has been provided. Such a composition may comprise at least one magnesium-counter ion compound. A magnesium-counter ion composition described herein may be useful for any of a variety of applications provided herein, such as maintaining, enhancing, and/or improving health, nutrition, and/or another condition of a subject, and/or cognitive, learning, and/or memory function. A magnesium-counter ion composition provided herein may be useful for administration to a subject presenting magnesium deficiency, mild cognitive impairment, Alzheimer'"'"'s disease, attention deficit hyperactivity disorder, ALS, Parkinson'"'"'s disease, diabetes, migraine, anxiety disorder, mood disorder, and/or hypertension. A kit, method, and other associated technology are also provided.

Claims

1. A method of enhancing cognitive function comprising administering to a subject a magnesium-containing compound (MCC) in an amount that is effective to enhance cognitive function, wherein the MCC comprises magnesium threonate.

2. The method of claim 1, further comprising measuring a body fluid concentration of magnesium in the subject after fasting for at least about twelve hours, wherein said body fluid concentration is serum concentration, plasma concentration or cerebrospinal fluid concentration.

3. The method of claim 2, wherein said body fluid concentration is cerebrospinal fluid concentration.

4. The method of claim 1, wherein said magnesium-containing compound is a contained in magnesium-supplemented foodstuff.

5. The method of claim 1, wherein said cognitive function is short-term memory or long-term memory.

6. The method of claim 1, wherein said magnesium-containing compound is administered for a period of greater than 1 month.

17. The method of claim 1, wherein the subject is an adult.

18. The method of claim 1, wherein the subject is a patient suffering from or diagnosed with dementia.

19. The method of claim 1, wherein the subject is a patient suffering from or diagnosed with Alzheimer'"'"'s disease.

7. A method of maintaining cognitive function comprising administering to a subject a magnesium-containing compound (MCC) in an amount that is effective to maintain cognitive function, wherein the MCC comprises magnesium threonate.

8. The method of claim 7, further comprising measuring a body fluid concentration of magnesium in the subject under a fasting condition, wherein said body fluid concentration is serum concentration, plasma concentration, or cerebrospinal fluid concentration.

9. The method of claim 8, wherein said body fluid concentration is cerebrospinal fluid concentration.

10. The method of claim 7, wherein said magnesium-containing compound is contained in a magnesium-supplemented foodstuff.

11. The method of claim 7, wherein said magnesium-containing compound is administered for a period of greater than 4 months.

12. The method of claim 7, further comprising the step of determining a starting body fluid concentration of magnesium of said subject under a fasting condition, wherein said starting body fluid concentration is serum concentration, plasma concentration, or cerebrospinal fluid concentration.

13. A method of therapeutic treatment of cognitive dysfunction or prophylactic treatment of magnesium deficiency-caused cognitive dysfunction, comprising administering to a subject in need of therapeutic or prophylactic treatment of cognitive dysfunction magnesium threonate in an amount that is effective for therapeutic or prophylactic treatment of said cognitive dysfunction.

14. The method of claim 13, wherein magnesium threonate is administered for at least about 1 month.

15. The method of claim 13, wherein magnesium threonate is administered for at least about 4 months.

16. The method of claim 13, further comprising measuring a body fluid concentration of magnesium after fasting for at least about 8 hours, wherein said body fluid concentration is serum concentration, plasma concentration, or cerebrospinal fluid concentration.
