Yoga exercises could stimulate the passage of (green) food and/or (originally green) bile through your bowel, and then either the food or bile would color the stool green. If stools are loose and contain undigested food, you are losing nutrients this way.
Excessive use of magnesium supplements can be toxic. The upper limit -- the highest dose a person can take -- of magnesium supplements is: 65 mg/day for children ages 1-3. 110 mg/day for children ages 4-8. 350 mg/day for adults and children ages 9 and up.
However, researchers believe that these would be too low of a starting dose for supplementation to correct deficiencies, and that around 600 mg would be a better starting dose. When Mg substitution is started, the minimum dose to be applied is 600 mg Mg per day.f you get loose stools or stomach upset at that magnesium dosage, then take it 3 or even 4 times per day for 3 to 4 days. Donât assume that you are taking too much magnesium simply because you have loose stools, but be sure to know the symptoms of a Magnesium Overdose and to stop taking it if you begin to feel worse.
