A single mom of two claims she beats the flu by drinking sperm smoothies.

Tracy Kiss, 29, from Buckinghamshire, puts a spoonful of her best friend’s donated semen into her drink every morning in a bid to boost her immunity.

The personal trainer, who is mom to Millicent, 9, and 4-year-old Gabriele, has previously advocated using sperm as a facial ointment.

On her bizarre beverage concoction, she said: “I’d been feeling run down and had no energy, but now I’m full of beans and my mood has improved.

“It can taste really good— depending on what my friend has been eating. My other mates think I’m strange, but I don’t give a toss.”
