The Marcus Rohrer Spirulina© farm in Hawaii

Spirulina has long been used for energy and endurance as well as many other health benefits such as immunity, eye health and cardiovascular health. New research published in the Journal of the American College of Sports Medicine shows that Spirulina may be the perfect nutrient for athletes and validates its positive effects on energy and endurance.

This double blind human clinical study compared treadmill endurance of subjects taking Spirulina versus placebo and found significant improvement in only four weeks of supplementation at a dosage of 6 grams per day. The researchers concluded: “We report for the first time that supplementation of Spirulina for 4 weeks increased exercise performance, possibly through an increase in fat oxidation rate and increased glutathione levels.” (Kalafati et al, 2009)

A natural product that makes you train harder and burn more fat during your training sessions... sounds a bit too good to be true?

Moderately trained participants took part in the double-blind, placebo-controlled study. Each subject received either the natural supplement spirulina or a placebo for 4 weeks. They were then asked to run on a treadmill at an intensity corresponding to 70%-75% of their VO2max for 2 hours and then at 95% VO2max until exhaustion.  Exercise performance was measured and blood samples were drawn before, immediately after, and at 1, 24, and 48 hours after exercise. 

The results showed a clear advantage in those taking spirulina. Time to fatigue after the 2 hour run was significantly longer after spirulina supplementation (2.05 minutes ± 0.68 minutes vs 2.70 minutes ± 0.79 minutes – around a 25% increase). Furthermore ingestion of spirulina significantly decreased carbohydrate oxidation rate by 10.3% and increased fat oxidation rate by 10.9% during the 2 hour run compared with the placebo trial.

The study used only relatively small amounts of Spirulina of just 6g a day, making these very achievable results for all of us in training.

It’s role as a whole food:

One of the key aspects for me is that is compensates for deficiencies in the diet and stimulates the metabolism.

You receive essential nutrients in a concentrated form without excess calories. It balances your blood sugar levels and gives you the energy you need during weight loss, which once you start restricting calories, most often than not you start to feel listless, tired, irritable and hungry!

Considered the most complete naturally cultivated nutrient in the world:

  • Approx. 60% complete digestible protein Contains every essential amino acid
  • More carotenoids than any other whole food
  • Rich in vitamins, minerals, trace elements, chlorophyll and enzymes

The National Research Council Committee on Diet and Health recommends that we eat 5-9 servings of fruit and vegetables a day. Even for a person who eats well, that’s a challenge.

Spirulina’s concentrated nutrition makes it an ideal food supplement for people of all ages and lifestyles.

1 Serving of Spirulina = 5 servings of fruits & vegetables
