Patient's Query
Hello doctor,
I am a 28-year-old male, who is trying to lose weight. I am overweight and I am physically active doing 15 thousand to 25 thousand steps every day. I am getting depressed during this weight loss journey and additionally, I am taking supplementation. As part of a supplementation strategy, if approximately 1000 mg of calcium is taken alongside approximately 900 mg of magnesium (primarily in the form of magnesium oxide), what would be the relative absorption rates of each mineral, considering their competition for absorption? Over the long term, could this dosage pose an increased risk of magnesium toxicity, particularly given the lower bioavailability of magnesium oxide? Should magnesium intake be reduced to optimize absorption rates and minimize toxicity risk?
Kindly suggest.
Hello,
Welcome to iCliniq.com.
I understand your concern.
Suppose you take approximately 1000 mg of calcium alongside 900 mg of magnesium (with magnesium primarily in the form of oxide). In that case, several factors will influence the absorption and long-term impact. Calcium and magnesium share some absorption pathways, particularly in the intestines. High calcium intake can interfere with magnesium absorption, and vice versa. Typically, an optimal calcium-to-magnesium ratio is around 2:1 for better balance, meaning your current intake (1000 mg calcium to 900 mg magnesium) could lead to some degree of competitive inhibition but might not completely block absorption. So, While your current calcium-to-magnesium intake ratio is relatively balanced, the high magnesium intake in oxide form may have limited immediate absorption but could pose risks over the long term. It would be wise to monitor for signs of magnesium overload and consider adjusting intake or switching to better-absorbed forms to avoid potential toxicity or gastrointestinal disorders.
I hope this helps.
Let me know if you have any other concerns.
Thank you.
