Guava Fruit Powder

Also known as: Guava, Guayaba, Psidium guajava

Overview

Guava fruit powder is derived from *Psidium guajava*, a tropical fruit renowned for its rich nutritional profile, containing vitamins A, C, E, dietary fiber, and various antioxidants. It is primarily utilized as a dietary supplement due to its potential health benefits, notably its antioxidant and antidiabetic properties. The fruit has been traditionally used in various cultures for its medicinal attributes. Despite moderate research maturity, including some clinical trials demonstrating its effects, further exploration through systematic reviews and meta-analyses is warranted to fully understand its therapeutic potential and applications.

Benefits

Guava fruit powder is primarily recognized for its ability to inhibit intestinal glucose absorption, which may aid in blood sugar control, particularly in individuals with diabetes or at risk of insulin resistance. A clinical trial indicated a statistically significant reduction in postprandial glucose levels among healthy adults, suggesting a promising role in glycemic management. Though the antioxidant capacities of guava fruits may offer additional health benefits, research on these secondary effects remains limited. More extensive studies are necessary to delineate the full range of benefits and the populations that might derive the most value from guava supplementation.

How it works

The primary mechanism of action for guava fruit powder involves the inhibition of sodium-dependent glucose cotransporters, specifically SGLT1, along with GLUT2 in the intestines. This action leads to reduced absorption of glucose, subsequently lowering blood sugar levels after meals. This interaction predominantly affects the gastrointestinal system and glucose metabolism, although comprehensive data on the bioavailability and absorption of guava fruit powder is not yet fully established.

Side effects

Overall, guava fruit powder is generally regarded as safe for consumption, though comprehensive safety data is lacking. Commonly associated side effects are not well-documented, but gastrointestinal discomfort may occur in some individuals. Rare side effects remain unknown, and while no specific contraindications have been established, caution is advised, particularly for individuals taking diabetes medications due to the potential for additive glucose-lowering effects. Pregnant or breastfeeding women should consult healthcare providers prior to use to ensure safety.

Dosage

The optimal dosing guidelines for guava fruit powder have not been definitively established, reflecting variability in traditional uses. There is no commonly recommended minimum effective dose, nor a defined maximum safe dosage. Individuals typically use guava in forms such as powders or extracts, and while timing considerations are not specifically noted, monitoring individual responses to supplementation is advised. Further research is required to provide solid recommendations on dosing for various health outcomes.
