Spinach Organic Vegetable Powder
Also known as: Spinach, Palak, Spinach Greens, Spinacia oleracea L.
Overview
Spinach, scientifically known as *Spinacia oleracea L.*, is a nutrient-dense leafy green vegetable widely recognized for its rich profiles of vitamins, minerals, and phytochemicals. Natural sources of spinach include fresh leaves and powdered extracts. It contains high levels of vitamins A, C, E, K, and minerals such as iron, potassium, and magnesium, along with phytochemicals like lutein, zeaxanthin, kaempferol, and nitrates. Spinach is commonly utilized as a dietary supplement for enhancing nutritional intake and supports overall health, potentially mitigating risks for chronic diseases. The body of research surrounding spinach shows a moderate to high maturity level, suggesting a good quality of evidence based on randomized controlled trials (RCT) and observational studies that advocate its health benefits.
Benefits
Spinach offers a variety of evidence-based health benefits. It has been shown to assist in weight management and metabolic health significantly, particularly in obese individuals. A RCT indicated that a daily intake of 5 g thylakoid-rich spinach extract led to a mean weight loss of -3.71 kg. Spinach also contributes to ophthalmic health by featuring lutein and zeaxanthin, compounds that may reduce the risk of age-related macular degeneration and cataracts. Secondary benefits include enhanced satiety and hunger control. Clinical studies have shown that consuming spinach extract can lead to reduced hunger and increased feelings of fullness. Spinach's antioxidant and anti-inflammatory properties may further support its effectiveness against chronic diseases such as diabetes, obesity, and cardiovascular conditions.
How it works
Spinach's health benefits stem primarily from its rich content of phytochemicals and bioactive compounds. The antioxidants in spinach scavenge reactive oxygen species, protecting against oxidative damage. Spinach modulates gene expression linked to metabolism and inflammation, and promotes the secretion of satiety hormones such as cholecystokinin and leptin. The interactions with metabolic pathways, digestive enzymes, and the eye's macular pigment showcase its comprehensive health-promoting mechanisms.
Side effects
Spinach is generally safe for most individuals when consumed in moderation as part of a balanced diet. Common side effects have not been reported extensively, but gastrointestinal discomfort may occur in some people if large amounts are ingested. Individuals on blood thinners, especially warfarin, need to monitor their intake of vitamin K found in spinach due to potential interactions. Those with kidney stones or impaired kidney function should also exercise caution due to spinach's high oxalate content. Pregnant or breastfeeding women are advised to consult healthcare professionals before starting any supplements.
Dosage
The recommended minimum effective dose of thylakoid-rich spinach extract powder for weight management and metabolic benefits is 5 g per day. An optimal daily range of 5-10 g is common in studies, although individual needs may vary. There is no established maximum dose, but caution is advised regarding gastrointestinal effects at higher intakes. It is best to consume spinach extract before meals to enhance satiety effects. The powdered form has higher efficacy than whole spinach for specific effects, and vitamin C can aid iron absorption from spinach.
