Delphinidin 3-O-glucoside (99.65 mg/100g) and cyanidin 3-O-glucoside provide [antioxidant protection](/ingredients/condition/antioxidant) through DPPH radical scavenging and lipid peroxidation prevention. Protocatechuic acid and gallic acid derivatives contribute to [anti-inflammatory](/ingredients/condition/inflammation) activity by inhibiting protein denaturation pathways. ## Clinical Summary Current evidence is limited to in vitro studies only, with no human clinical trials reported for pitanga seed specifically. Laboratory studies demonstrate alpha-glucosidase inhibition with IC50 values comparable to acarbose (8.8-12.8 mg/mL) and pancreatic lipase inhibition similar to orlistat (5.8 mg/mL). [Anti-inflammatory](/ingredients/condition/inflammation) activity shows 81.7-82.5% protein denaturation inhibition in purple and orange varieties. The absence of human trials significantly limits clinical applicability and requires cautious interpretation of potential therapeutic benefits. ## Nutritional Profile - Phytochemicals: Flavonoids, Tannins, Polyphenols, Essential oils - Fatty Acids: Oleic acid (Omega-9), Linoleic acid (Omega-6) - Minerals: Magnesium, Zinc, Calcium, Iron ## Dosage & Preparation - Common Forms: Available as dried seed powder or concentrated extracts. - Traditional Use: In Amazonian and Indigenous Brazilian medicine, seeds were brewed into teas or decoctions for metabolic balance, [digestion](/ingredients/condition/gut-health), and [liver detox](/ingredients/condition/detox)ification. - Modern Use: Integrated into metabolic health supplements, gut-support formulations, [cardiovascular](/ingredients/condition/heart-health) wellness products, and functional skincare. - Dosage: Consume 500-1,500 mg of seed extract daily, or 2-4 grams of dried seed powder, for metabolic, digestive, and [anti-inflammatory](/ingredients/condition/inflammation) support. ## Safety & Drug Interactions Literature indicates apparent low toxicity in mammals with minimal reported adverse effects from pitanga fruits and seeds.

In vitro studies show pitanga seed extracts inhibit alpha-glucosidase with IC50 values comparable to the diabetes drug acarbose (8.8-12.8 mg/mL). However, no human clinical trials exist to confirm blood sugar benefits in people with diabetes or prediabetes. ### What is the main active compound in pitanga seed? Proanthocyanidins are the primary bioactive compounds, along with anthocyanins like delphinidin 3-O-glucoside at concentrations of 99.65 mg/100g lyophilized fruit. These compounds are responsible for the antioxidant and enzyme-inhibitory effects observed in laboratory studies. ### Is pitanga seed safe to consume daily? While studies indicate low toxicity in mammals, comprehensive safety data for regular consumption of pitanga seed extracts is lacking. The absence of human trials means optimal dosing and long-term safety profiles remain unknown. ### Can pitanga seed help with weight loss? Laboratory studies show pitanga extracts inhibit pancreatic lipase with IC50 values comparable to orlistat (5.8 mg/mL), suggesting potential fat absorption reduction. However, no human studies have tested weight loss effects, making clinical efficacy claims unsupported. ### What's the difference between pitanga fruit and seed benefits? Both contain similar bioactive compounds like proanthocyanidins and anthocyanins, but concentrations may vary between fruit flesh and seeds. Most research focuses on whole fruit extracts rather than isolated seed preparations, limiting specific comparisons of bioactivity between parts. ### Does pitanga seed interact with diabetes medications? Pitanga seed may potentiate the effects of blood sugar-lowering medications due to its insulin-sensitizing polyphenols, potentially increasing hypoglycemia risk. If you are taking diabetes medications such as metformin, sulfonylureas, or insulin, consult your healthcare provider before adding pitanga seed supplementation. Dose adjustments of your medication may be necessary when combining it with pitanga seed. ### What is the most effective form of pitanga seed supplement?
