Can I Take Trans-Resveratrol? Understanding Dosage and Guidelines

Trans Resveratrol

      Trans-resveratrol, a compound derived from plants, has gathered significant interest due to its potential health advantages. Belonging to the group of phytoalexins, which plants produce as a defence against diseases and environmental stressors, it has shown promise in improving various health concerns. 

      Dosage and Administration

      The recommended dosage of trans-resveratrol can vary depending on the specific condition being addressed. It's essential to follow the dosage instructions provided on the product packaging or consult a healthcare professional before taking trans-resveratrol. While resveratrol generally has low toxicity and is well tolerated up to 5 grams per day, exceeding this amount may lead to gastrointestinal discomfort. To avoid potential side effects, it's best to stick to the recommended dosage.

      • Dosage: Adults are advised to consume between 250mg to 1500mg of trans-resveratrol daily. Beginning with a lower dose and observing your body's response before making adjustments is recommended. It's important to note that the appropriate dosage may vary depending on the specific brand and type of trans-resveratrol supplement being used.
      • Timing: When Trans-Resveratrol is taken with NMN: For optimal outcomes, it's advised to consume trans-resveratrol in the morning when paired with nicotinamide mononucleotide (NMN). This blend has demonstrated positive impacts on ageing and associated ailments.
      • If Trans-Resveratrol is taken Alone: If you're consuming trans-resveratrol without NMN, it's advisable to take it in the evening post-dinner. This approach may help minimize potential side effects and enable the compound to function effectively overnight.

      What are the possible side effects of Resveratrol?

      Like any medication or supplement, it's crucial to be aware of potential side effects. Fortunately, there have been no reported adverse effects of resveratrol in humans, as evidenced by a small 2011 clinical trial administering 150 mg daily to obese patients without any negative reactions. However, it's still essential to adhere to recommended dosages and consult your doctor if you encounter unexpected side effects. Since resveratrol is relatively new, unknown long-term side effects may exist, emphasizing the importance of using it as directed and closely monitoring your health.

      Contraindications and Interactions

      Although trans-resveratrol is typically safe for most individuals, there are specific groups who should refrain from its consumption. These include children in their growth phase, females experiencing menstruation, and individuals diagnosed with anaemia. This caution stems from resveratrol's ability to bind with essential minerals like copper and iron, vital for these demographic groups. Additionally, trans-resveratrol might interact with certain medications, such as carbamazepine, and other substances metabolized by the CYP3A4 enzyme. Hence, it's crucial to seek guidance from a healthcare provider before commencing trans-resveratrol supplementation, especially if currently using any medications.
