Sage Powder Extract

Also known as: Sage, Common Sage, Garden Sage, Dalmatian Sage, Sage Powder Extract, Salvia officinalis

Overview

Sage (*Salvia officinalis* L.) is a perennial herb indigenous to the Mediterranean, renowned for both its culinary and medicinal applications. The leaves are distinguished by their richness in bioactive compounds, notably essential oils such as thujone and rosmarinic acid. Sage extract is predominantly recognized for its potential to enhance cognitive function, while also exhibiting antioxidant and anti-inflammatory properties. The body of research suggests a moderate efficacy in boosting cognitive performance in populations of all ages, particularly in improving short-term memory and attention. Studies supporting these benefits are primarily randomized controlled trials (RCTs) and systematic reviews, highlighting the need for further long-term studies to solidify these findings.

Benefits

Sage extract is primarily associated with cognitive enhancement, with acute doses ranging from 150-300 mg demonstrating significant improvements in short-term episodic memory and attention, particularly noted among healthy young adults and older individuals. Evidence shows moderate effect sizes, notably illustrated by a study using the CogTrack™ system, which highlighted marked improvements in cognitive tasks following sage administration. Additionally, sage's antioxidant and anti-inflammatory properties contribute to overall cognitive health, with effects typically observed within one hour post-administration. Despite these benefits, further studies are necessary to determine long-term effects and clinical significance.

How it works

The cognitive-enhancing properties of sage extract are largely due to its cholinergic effects, primarily through the inhibition of acetylcholinesterase, thus increasing acetylcholine levels which facilitates memory and attention functions in the central nervous system. Furthermore, the antioxidant properties, particularly from rosmarinic acid, play a crucial role in mitigating oxidative stress in the brain, promoting neuronal health. The method of extraction is significant, as bioavailability is typically higher in ethanol-based extracts.

Side effects

Sage extract is generally regarded as safe when consumed in moderate amounts, with common adverse effects being rare and no consistent negative outcomes reported above 5% usage. However, rare but serious side effects may arise at high doses due to thujone, including potential neurotoxic effects such as seizures. Individuals on central nervous system-affecting medications should consult healthcare providers prior to use due to potential interactions. Pregnant, breastfeeding women, and those with epilepsy should exercise caution, as high doses may exacerbate their conditions. Vulnerable populations, including children and the elderly, should also be considered due to the limited scope of research on sage extract's impact on these demographics.

Dosage

For cognitive enhancement, the effective dosage of sage extract is typically between 150 mg and 300 mg per day, ensuring a standardization of at least 2.5% rosmarinic acid. Optimal cognitive benefits are usually observed within one hour of intake. While no established maximum safe dose exists, exceeding 300 mg is discouraged due to the risk of thujone-related toxicity. Ethanol-based extracts are preferred for maximizing bioavailability, and although no specific cofactors are required for absorption, the formulation may influence its bioavailability.

FAQs

Is sage extract safe?

Sage extract is generally safe at recommended doses, but high doses or prolonged use should be avoided due to the risk of thujone toxicity.

When should I take sage extract?

Cognitive benefits are typically observed within one hour of administration, making it suitable for tasks requiring focus.

What improvements can I expect?

You can expect improvements in short-term episodic memory, attention, and working memory with proper dosing.

Can sage extract replace my medication?

No, sage extract should not be used as a substitute for medical treatment; it is an adjunct supplement for cognitive benefits.
