Taking Creatine with L-arginine: Is it SAFE or Not?

Short Answer: It is generally safe to take creatine and L-arginine together or one after another.

Creatine and L-arginine are both healthy supplements.

Creatine is a compound that helps the body produce energy for muscle contraction.

L-arginine is an amino acid that helps the body synthesize nitric oxide, a molecule that relaxes blood vessels and improves blood flow.

According to Ayurveda, creatine and L-arginine have different effects on the body’s doshas, or energies.

Creatine increases the fire element (pitta), while L-arginine increases the air element (vata).

Therefore, taking them together may create an imbalance in the body and cause health problems.

But according to science, there is not much evidence to support or refute the benefits or risks of taking creatine and L-arginine together.

Some studies suggest that combining them may enhance exercise performance by increasing power output and blood flow to the muscles.

However, other studies have found no significant effects or even negative effects of L-arginine supplementation on exercise performance.

As a nutritionist, my advice is to try first.

If after taking creatine and L-arginine together you experience side effects such as nausea, diarrhea, bloating, gout, headache, or allergic reaction, then stop combining them. And if you can tolerate them, then continue.

However, you should be mindful of the quality and quantity of creatine and L-arginine you consume.

Because too much creatine can cause kidney damage, dehydration, muscle cramps, or weight gain. And too much L-arginine can cause low blood pressure, bleeding disorders, asthma symptoms, or herpes outbreaks.

Whether you take them together or not, you should always choose high-quality supplements from reputable brands.

Because some supplements may contain contaminants or additives that can harm your health.

You should also consult your doctor before taking any supplements, especially if you have any medical conditions or take any medications.

You can store creatine and L-arginine in a cool, dry place away from sunlight and moisture. Do not store them in the refrigerator or freezer, as this may affect their potency.

You should also check the expiration date and discard any expired supplements.

Finally, remember, creatine and L-arginine are not magic pills that can replace a balanced diet and regular exercise. They are only meant to supplement your nutrition and enhance your performance.

You should always follow the recommended dosage and instructions on the label and do not exceed the safe limits.
