Creatinine is a chemical waste produced by muscles during their normal breakdown process. It is a crucial component used to assess kidney function through blood tests. Monitoring and maintaining the creatinine level normal range is essential for diagnosing and managing kidney disorders or Vrikka-Vikara [2], as well as evaluating overall health. [1] 

According to Ayurveda, CKD, or Chronic Kidney Disease, is a disease affecting the Mutravaha Srotas (urinary system). All three Doshas (Vata, Pitta, and Kapha) and all the Dushyas (tissues) are involved in the disease, but Kapha is primarily responsible for blocking microvessels and causing microangiopathy. On the other hand, Vata plays a role in the degeneration of the kidney’s structure. [2]

In this article, we will explore creatinine’s normal range, the significance of creatinine blood tests, factors that can influence creatinine level normal range, and strategies to maintain urine creatinine normal range mg dl naturally.

Creatinine Blood Test and Normal Range

A creatinine blood test measures the amount of creatinine in the blood, reflecting how well the kidneys are functioning. The test is commonly requested by healthcare professionals to evaluate kidney function, especially when kidney disease is suspected. The creatinine normal range in the blood can vary depending on various factors such as age, sex, muscle mass, and the laboratory performing the analysis. However, in adults, the typical serum creatinine test normal range is approximately 0.6 to 1.2 milligrams per deciliter (mg/dL) for males and 0.5 to 1.1 mg/dL for females. [1]

Significance of Creatinine Blood Test

The creatinine blood test is a key indicator of kidney function and is used to diagnose and monitor various kidney conditions. Patients who are already afflicted by chronic and uncontrolled diabetes and hypertension are particularly vulnerable to kidney disease. When kidney function is impaired, creatinine test normal range in the blood tends to get affected and rise, indicating reduced filtration capability. [1]

Some of the conditions and situations in which creatinine blood tests are used include:

  1. Chronic Kidney Disease (CKD):

The creatinine blood test is often used to diagnose and stage CKD which is known to affect several kidney compartments. A persistent increase from the creatinine normal range over time may indicate declining kidney function.

  1. Acute Kidney Injury (AKI): 

Rapid and significant increases in creatinine levels can indicate acute kidney injury, often caused by factors like dehydration, infection, or drug toxicity. [1]

Factors Affecting Creatinine Levels

Several factors can influence creatinine levels, and it’s essential to consider them when interpreting the results of a creatinine blood test:

a) Race and Gender

Individuals from certain races and males usually have higher creatinine levels due to differences in muscle mass.

b) Muscle Mass

Creatinine is produced by muscle metabolism. Individuals with more muscle mass tend to have higher creatinine levels.

c) Diet

A diet rich in red meat and protein can increase creatinine levels, as creatinine is a byproduct of protein breakdown.

d) Certain Medications

Some medications, such as trimethoprim-sulfamethoxazole, can influence the serum creatinine normal range and increase it by about 0.4 to 0.5 mg/dL. [1]

How to Lower Creatinine Levels Naturally

If a person’s creatinine normal range is consistently elevated and indicates potential kidney dysfunction, it is essential to address the underlying causes. Here are some natural strategies that may help lower creatinine levels:

Increase fiber intake in diet

how to lower creatinine levels

Studies have shown that the consumption of foods enriched with fiber lead to a decrease in serum creatinine levels from the baseline value of 216 ± 26 to 201 ± 23 mmol/L (2.44 ± 0.30 to 2.27 ± 0.26 mg/dL; P < .05). These results indicate that the inclusion of fiber-rich foods in the diet positively impacts creatinine normal range and kidney function markers, suggesting potential benefits for overall kidney health. [3]

Monitor Medications

Avoid certain over-the-counter medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) and antacids. [4]

Ayurvedic Management

Using Ayurvedic treatment judiciously can provide relief to CKD patients. In Ayurvedic management of CKD and maintaining urine creatinine normal range, preventing and repairing tissue damage is crucial, and this can be achieved using:

Rasayana drugs: 

These can potentially enhance tissue qualities, thereby increasing tissue resistance. These drugs also promote urine filtration by causing Rakta bhar vridhi, acting as shothaghna (anti-inflammatory), and relieving muttrakrichha (urinary obstruction) thus helping achieve the urea creatinine normal range.

Ayurvedic Lekhana drugs: 

To address blockages, a scraping effect on blocked channels is utilized. Goksuradi guggulu, an Ayurvedic preparation, is considered a Rasayana for Mutravaha Srotas, and it also possesses Lekhana (scraping) effects due to the presence of Guggulu (Commiphora Weightii). This preparation serves as an effective diuretic, leading to increased sodium excretion. Chandraprabha Vati and Vrikkadoshahara Vati are other Ayurvedic formulations that complement the effects of Goksuradi guggulu. [2] Punarava, also known as Boerhavia diffusa, is another potent herb with diuretic and renal activities. It is used in traditional medicine to support kidney health and may aid in kidney regeneration. [5] You can get the purest form of the herb through Zandu Punarnava Capsules, highly effective in treating UTIs and several other excretory issues. Visit to place your order right away!


What lifestyle measures can be adopted to maintain the creatinine normal range?

Stay Hydrated: Ensuring an adequate water intake can help maintain kidney function and prevent dehydration, which might lead to elevated creatinine levels.
Reduce Protein Intake: If a high-protein diet is suspected of contributing to elevated creatinine levels, reducing protein intake and choosing plant-based protein sources may be beneficial when possible.
Maintain a Balanced Diet: A well-balanced diet, including fruits, veggies of various types, legumes, whole grains, and lean proteins, can support overall kidney health.
Regular Exercise: Engaging in daily physical activity, such as walking or swimming, can improve overall health and may indirectly support kidney function.
Avoid Nephrotoxic Substances: Minimize or avoid exposure to substances that can harm the kidneys, such as certain medications, chemicals, and illicit drugs.
Manage Underlying Conditions: Properly managing conditions like high blood pressure and high blood sugar can help prevent kidney damage and preserve kidney function.
Quit Smoking and Limit Alcohol: Smoking and excessive alcohol consumption can harm kidney health, so quitting and limiting alcohol intake is advisable.

When should you be worried about your creatinine ratio?

Elevated creatinine levels that deviate from the creatinine ratio normal range are a cause for concern when they surpass 1.3 mg/dL, indicating higher than normal values. However, in adults, creatinine levels above 5.0 mg/dL, and in infants, levels above 2.0 mg/dL are considered significantly high and indicative of a severe kidney disorder.

What is the creatinine ratio for kidney failure?

The BUN/Creatinine ratio is a useful indicator in identifying the cause of renal failure. Normally, when you maintain the creatinine normal range, this ratio falls within the range of 10:1 to 20:1. However, an elevated ratio could indicate conditions that reduce blood flow to your kidneys, such as congestive heart failure (CHF) or dehydration.


The creatinine blood test is vital for evaluating kidney function and detecting kidney disorders. The blood creatinine normal range can vary depending on age, sex, muscle mass, and individual factors. Elevated creatinine levels can indicate potential kidney dysfunction and may require further investigation and intervention. By following natural strategies such as staying hydrated, maintaining a balanced diet, and managing underlying health conditions, individuals can support kidney health and potentially achieve creatinine levels normal range.
