What is the upper limit for magnesium per day
The upper tolerable intake level (UL) for magnesium from supplements/pharmacological sources is 350 mg/day for adults (set by the Institute of Medicine). This limit applies to supplemental magnesium only - dietary magnesium from food does not have an established upper limit because excess is excreted by the kidneys.

Here is a complete breakdown of the magnesium upper limit:
Magnesium - Tolerable Upper Intake Level (UL)
The UL applies only to supplemental magnesium (from dietary supplements and medications) - NOT to magnesium naturally present in food.
Adults (19+ years): 350 mg/day from supplements
This applies equally to men, women, pregnant, and lactating adults.
Full UL by Age Group (Supplemental Magnesium)
| Age | UL |
|---|---|
| 0-12 months | None established |
| 1-3 years | 65 mg |
| 4-8 years | 110 mg |
| 9-13 years | 350 mg |
| 14-18 years (incl. pregnant/lactating) | 350 mg |
| 19+ years (incl. pregnant/lactating) | 350 mg |
Source: Institute of Medicine / National Academies Food and Nutrition Board (1997), confirmed by NIH Office of Dietary Supplements
Why 350 mg?
Exceeding this level from supplements can cause:
- Mild: Diarrhea, nausea, abdominal cramping (most common)
- Severe (very high doses): Hypotension, vomiting, difficulty breathing, irregular heartbeat, cardiac arrest, and in rare cases, fatal hypermagnesemia
Why no UL for dietary magnesium?
Healthy kidneys efficiently excrete excess magnesium absorbed from food, so there is no documented risk of toxicity from food sources alone.
Recommended Daily Allowance (RDA) vs. UL
The RDA for adults ranges from 310-420 mg/day from all sources (food + supplements combined). The 350 mg supplemental UL means you should not take more than 350 mg in supplement form on top of your dietary intake - unless directed by a healthcare provider.
What do you mean by 10 sets like 10 sets of each variation or total sets of all and Tomorrow I will be doing Bro microalbumin urine test how much do you think i will get
I don't have any context about "10 sets" - this appears to be your first message to me in this conversation, so I'm not sure what exercise or workout plan you're referring to. Could you give me more details?
As for the microalbumin urine test - I have no information about your health history, kidney function, diabetes status, blood pressure, diet, or any other factors that would let me predict your result. I cannot and should not guess a lab value for you - that would be irresponsible.
What I can tell you is:
Normal microalbumin (urine) reference ranges:
- Random urine: < 30 mg/g creatinine (albumin-to-creatinine ratio)
- 24-hour urine: < 30 mg/day
- Microalbuminuria (abnormal): 30-300 mg/day
- Macroalbuminuria (frank proteinuria): > 300 mg/day
Factors that can temporarily raise your result:
- Heavy exercise in the 24-48 hours before the test
- Fever or illness
- High protein meal before the test
- Dehydration
- Urinary tract infection
- High blood pressure
Tips before your test tomorrow:
- Avoid intense exercise today
- Stay well hydrated
- Follow any specific instructions your doctor gave you
Your doctor is the right person to interpret the result in the context of your full medical history.I can see these are your lab reports from Manipal/Pal Hospitals, collected on 31 Aug 2025, for Vennapusa Bhagirath, 17 years, Male. Let me read all of them carefully.
Here is a full summary and interpretation:

Key Takeaways
Overall - your reports are largely normal for a 17-year-old male. A few minor things worth noting:
-
Sodium 135.5 - just 0.5 below the lower limit. This is barely outside range and often due to hydration status at time of sample. Not concerning on its own.
-
Indirect bilirubin slightly raised (0.43, ref 0.10-0.30) - with all other liver tests normal, this pattern (isolated indirect bilirubin rise) in a young person is very commonly Gilbert's syndrome - a benign, harmless genetic variation. Not a disease.
-
SGPT 48 - within range (limit is 50). Fine.
-
Neutrophils/Monocytes mildly elevated - could reflect a mild infection or stress at the time of the test. Not alarming.
-
No protein in urine - this is a good sign going into your microalbumin test tomorrow. The urine routine showed zero protein, which suggests your kidneys are filtering well. That's a positive indicator.
About Tomorrow's Microalbumin Test
Based on these reports - your creatinine is normal (0.75), urea is normal, urine routine shows no protein - your kidneys appear to be functioning well. These are all good signs. However, I still cannot predict a specific number for you - the microalbumin test is more sensitive and detects very small amounts that routine urine protein tests miss. Your doctor ordered it for a specific reason and will interpret it in full context.
