Your daily dentil hygiene might be affecting your heart, brain and fertility.

Like other GLP-1 medications, the Wegovy pill can occasionally cause more serious side effects, including:

  • UK availability: Now approved by the MHRA. Available to pre-order with Blume, with stock expected in the coming weeks
    • Mechanism of action: GLP-1 receptor agonist, the same active ingredient (semaglutide) as the Wegovy injection

If you experience severe stomach pain, severe vomiting, or any signs of an allergic reaction, seek medical attention straight away.

What is Ferritin?

Ferritin is a protein complex that stores iron in a safe, soluble, and non-toxicform, helping regulate iron levels and prevent damage from free iron [1]. By safelysequestering iron, ferritin protects cells from oxidative stress, which can occurwhen free iron reacts with oxygen, generating harmful free radicals.

Ferritin is made up of two types of subunits: heavy (H) chains, which handle therapid oxidation of iron, and light (L) chains, which manage long-term iron storage[2]. This combination ensures that iron is readily available when needed foressential functions like oxygen transport, energy production, and cell growth.

Each ferritin molecule can hold up to 4,500 iron atoms, making it anefficient iron storage system [2]. When the body requires iron, ferritinreleases it in a controlled manner.

Beyond iron storage, ferritin is critical in maintaining cellular functional andresponding to inflammation. As an acute-phase reactant, ferritin levels risesignificantly in response to inflammation, infection, or tissue damage, making ita sensitive marker for both iron metabolism and systemic inflammation [3, 4]. Thisis especially evident in chronic conditions such as autoimmune diseases,
