Interaction Details
Insulin Lispro Recombinant is classified as belonging to the following category: Antidiabetes Drugs
Theoretically, taking blue-green algae with antidiabetes drugs might increase the risk of hypoglycemia.
Human research shows that spirulina blue-green algae can have hypoglycemic effects in patients with diabetes, at least some of whom were using antidiabetes drugs. However, blue-green algae does not seem to improve glycated hemoglobin (HbA1c) levels in patients with diabetes. A meta-analysis of animal studies also suggests that spirulina blue-green algae have hypoglycemic effects.

Blue-green Algae Overview
Blue-green algae, also known as cyanobacteria, are a type of aquatic microorganism. The term 'blue-green algae' can refer to many different types of algae, including Arthrospira genus, which is known as spirulina, and Aphanizomenon flos-aquae, commonly known as 'Klamath', as it is found in Klamath Lake, Oregon.
Blue-green algae contain several different nutrients, including vitamins A, B6, B12, E, and K, iron, manganese, zinc, sodium, potassium, phosphorus, calcium, magnesium, copper, selenium, and chromium.
Blue-green algae have been shown in some samples to be contaminated with several types of toxins, including microcystins and heavy metals, so it is important to only take supplements that are properly tested, processed, and produced.
