Nutritional supplements that claim to boost endurance naturally are nothing new. But in many cases, the scientific studies have just not been there to back the claims. So might be the case with VAAM Energy Hornet Juice, a sports drink that claims to boost athletic performance and sustain energy.

VAAM (Vespa Amino Acid Mixture) contains a synthetic version of liquids secreted by the Vespa mandarinia – or Asian Giant Hornet – which is a very large-sized wasp with a body length of 27 – 45 mm which includes a quarter-inch stinger. The queen can reach 5.5 cm! The insects have the ability to fly as many as 50-60 miles per day at a speed of 25 miles an hour.

Back in 2000, Japanese long-distance runner Naoko Takahashi won Olympic gold for the women’s marathon in Sydney with a record time of 2:23:14. She attributed her success to the use of Hornet Juice. Other top athletes in Japan say the drink works wonders in preventing dehydration, maintaining energy levels and preventing fatigue.

But, of course, the scientific studies into the supplement have been few and small.

In 2001, researchers in Japan studied the effects of VAAM using six healthy young male subjects exercising on a treadmill. The researchers found that the men experienced an increase in fat oxidation, thus the claims that the product helps the body use fat for energy during exercise and could potentially aid weight loss.

In a second study, based on the theory that amino acids, especially branched chain amino acids (BCAA), improves exercise activity, researchers created an amino acid mixture using 1.8% VAAM collected from V. mandarinia larvae and fed it to mice. The mice given VAAM were able to swim longer t han those given other amino acid mixtures.

A third study involved a total of 24 healthy male subjects consisting of endurance runners, sprinters, soccer players and men who were sedentary. The athletes given VAAM appeared to experience a reduction in physical stresses which then helped them to improve their overall training ability.

Most recently, Hornet Juice was tested on 24 sedentary women in their 60’s. The researchers claim that combined with a 90 minute twice-a-week workout, VAAM helped increase aerobic fitness and decrease abdominal fat.

As you can see, these studies are very small and some are more than 10 years old. Today, the FDA has not approved any claims that VAAM Hornet Juice is either effective for improving athletic endurance or for weight loss. Nor has its safety been tested among a wider group of people.

Additionally, the supplement is quite expensive – at $2.50 per serving.

For athletic endurance, skip the bee pollen, worm-and-turtle soup, and reindeer milk (all of which have been used – and sworn to be effective by testimonials! – by successful athletes). Instead, train appropriately, giving importance to rest and recovery days, and try adding some of these endurance-boosting superfoods to your diet:

1. Quinoa – it contains all nine essential amino acids which are critical to the functioning of the human body. It is also a good source of manganese, magnesium, iron, zinc, potassium, and calcium.

2. Kale – this leafy green is full of nutrients for athletic performance, including magnesium, vitamin C, calcium, folate, zinc and iron.

3. Bananas – the “perfect” food to consume 30 minutes before an endurance race because they are packed with complex carbs and potassium (which minimizes cramping and helsp the cardiovascular system function.)

4. Chia Seeds – one of nature’s highest plant-based sources of complete protein. The ancient grain has been used for centuries by the Aztecs and the Mayans as an energy source.

5. Lean Beef – Iron is a crucial nutrient for endurance athletes because a deficiency leads to fatigue.

6. Sports Drinks – Gatorade, Powerade and the like are cheaper than Hornet Juice and provide the carbohydrates, electrolytes, and fluid to get you through long periods of exercise.
