Is there fructose in Hammer Gel?

Q: I have fructose intolerance and wonder whether I can take Hammer Gel. I know that Hammer Gel does not contain any added fructose, but it contains fruit juices; thus, there should be some natural fructose in it. Any experience with this condition?

A: Fructose is a real and present dietary danger known and shown to compromise health. Unprocessed natural fruit juice is associated with health-enhancing effects, but the processed form is highly toxic even in relatively small amounts. This question is important, requiring a few paragraphs to explain.

Hammer Gel - Fructose Question
A typical 36-gram serving Hammer Gel contains 0.72 gram from a natural sweetener, called "Energy Smart" made from 50% fruit juice and 50% grain dextrins via proprietary process. Fruit juice contains natural fructose of 3-10% by weight. For every serving of Hammer Gel consumed (at most) 1-2 grams of natural fructose is consumed. The natural fructose content in Hammer Gel for a 9-serving/3-hour workout is no higher than 18-20 grams, well under half of the 50 grams necessary to induce fructose intolerance symptoms. Since no one knows the proprietary process by which the "Energy Smart" sweetener formula is processed, my comment is an educated estimate. When compared to natural organic whole foods, Hammer Gel generates very small amounts of natural fructose.

Naturally occurring, plant-source total dietary fructose ingested from whole non-processed fruits or vegetables is around 15 grams per day with NO reported association with compromised health disorders.

Each 3.5 ounces from whole fruits contain small gram amounts of fructose:

How Much Fructose is Harmful?
Most dietary fructose intake is ingested as processed High-Fructose Corn Syrup (HFCS), used to sweeten various packaged foods. Processed Food manufacturers prefer HFCS as a sweetening agent because it is cheap and mixes well in many foods. Dietary fructose intake is increasing. From 1970-1997, annual per capita intake of HFCS in the USA increased from 0.23 kg to 28.3 kg. During the same period, total Fructose + Sucrose intake increased from 64 grams per day to 81 grams per day. Fifty-five percent (55%) of the dietary fructose Americans consume comes from commercially produced high-fructose corn syrup (HFCS) which is added to many processed foods (e.g. Most soft drinks contain approximately 11% HFCS), to sweeten baked goods, canned fruits, dairy products, ketchup and jams. Soft Drinks account for 33% of the total content of Simple Sugars (Fructose + Sucrose + Glucose) in the USA.

Fructose is absorbed primarily via the jejunum; however, one out of every three persons cannot completely absorb fructose. Fructose is slowly absorbed by the human digestive system. Peak serum fructose concentrations occur 30-60 minutes after fructose ingestion. The concentration of fructose in fasting blood of healthy humans is typically 1 mg/dL or less. The fructose portion of sucrose is absorbed more slowly than fructose ingested in its pure monosaccharide form. This is because the fructose portion of sucrose is not available for absorption until sucrose is hydrolyzed by intestinal digestive enzymes. The cell structures of animals fed fructose age more rapidly and accelerated aging of the collagen content of the skin also occurred (Journal of Nutrition. September 28, 1998:1442-1449.) Chronic or excessive use of processed fructose (apart from fruit fibers, vitamins, and other plant-sourced minerals) is associated with abnormal blood clotting ailments, increased cardiovascular disease risk, hypertension, colic, diarrhea, irritable bowel syndrome, breast cancer, colon cancer, calcium oxalate kidney stones & gallstones, increased total serum cholesterol levels, increased LDL cholesterol, cross-linking (glycosylation), increased risk diabetes mellitus type II, fatigue, fatty liver, insulin resistance, obesity, elevated serum triglycerides, gout, depression, tooth decay, and accelerated skin wrinkling. Two out of three otherwise normal/healthy persons experience fructose intolerance (fructose malabsorption form) when 50 grams of processed fructose or more is consumed. Choi's research associates the 50-gram fructose dose with fructose intolerance (Am J Gastroenterol 98(6):1348-1353, 2003). An average 600 ml of soft drink contains a whopping 32.6 grams of fructose!


A few grams natural fructose wrapped in its original cellulose fiber and fluid-like container always includes the enzymes, vitamins, and minerals making this substance well tolerated in up to 50 grams +/- 10 grams. However, the more processed and stripped of its original fiber, fluid, vitamin, and mineral content, the more likely a 50-gram amount, +/- 10 grams, will do more harm than good for healthy cellular metabolic function.
