What Makes Dr. Fuhrman's Gentle Care Formula Unique

Since most people’s diets are not ideal and individual absorption and utilization varies from person to person, it makes sense to recommend that all people take a high-quality multiple to assure most favorable vitamin D, B12, zinc, iodine, and selenium status, to name a few. 

Even if your diet is ideal, some people require more of certain nutrients than others. For example, it is not uncommon for some people to need extra vitamin D, or extra B12, even when their diets contain typical amounts of these vitamins. This is especially true regarding vitamin D because of the depletion of the atmosphere’s ozone layer and subsequent increase in skin damage from the sun. Because of this, many people practice sun avoidance and wear sunscreen, which decreases their vitamin D production.

I also took into consideration my recommendation to avoid all salt added to food. Salt is iodinated, making it the primary source of iodine in most people’s diets. Therefore, a multiple will assure adequate iodine intake in those who avoid adding salt to their diet.

Are there any problems with taking supplements?

The main problem with taking a typical multivitamin is that it may expose you to extra nutrients that you do not need. Sometimes too much of certain nutrients can have toxic or harmful effects. For example, I do not recommend taking supplements that contain folic acid, vitamin A, isolated beta-carotene, iron, or copper because there are risks associated with consumption of these nutrients above what we receive in our diet.

Ingesting vitamin A or beta-carotene in isolation—from supplements, instead of from food—may interfere with the absorption of other crucially important carotenoids, such as lutein and lycopene, thus potentially increasing cancer risk.1

The precursor to vitamin A, beta-carotene once was regarded as a safe and beneficial antioxidant and even recommended as an anti-cancer vitamin, but it has recently been shown to increase the risk of certain cancers when administered as an isolated supplement. Scientists now suspect that problems may result when beta-carotene is ingested without other carotenoids that would have been present had it been ingested from real food. Beta-carotene is only one of about 500 carotenoids that exist. Beta-carotene supplements are poor substitutes for the broad assortment of carotenoid compounds found in plants.

Copper has been removed from Dr. Fuhrman’s Gentle Care Formula. Recent studies have shown that excess copper could be associated with reduced immune function and lower antioxidant status. Recently published research also indicates that high copper intake and diets high in saturated and trans fats could lead to an accelerated rate of mental decline in older adults.

Why did researchers think that beta-carotene had such a powerful anti-cancer effect?

They had found that populations with high levels of beta-carotene in their bloodstream had exceedingly low rates of cancer. Recently, it was discovered that the reason these people were protected against cancer was because of hundreds of carotenoids and phytochemicals in the fruits and vegetables they were consuming. It wasn’t that beta-carotene alone was responsible for the benefit; it was merely that it had served as a flag or marker for those populations with a high fruit and vegetable intake. Unfortunately, many scientists confused the flag for the ship.

In Finnish trials, those using beta-carotene supplements failed to prevent lung cancer, and there was actually an increase in cancer in those who took the supplement.2 This study was halted when the physician researchers discovered the death rate from lung cancer was 28 percent higher among participants who had taken the high amounts of beta-carotene and vitamin A. Furthermore, the death rate from heart disease was 17 percent higher in those who had taken the supplements compared to those just given a placebo.3 Another recent study showed similar results, correlating beta-carotene supplementation with an increased occurrence of prostate cancer.

As a result of these European studies, as well as similar studies conducted here in the United States,4 articles in the Journal of the National Cancer Institute,5 the Lancet,6 and the New England Journal of Medicine all advise people to stop taking beta-carotene supplements.

How have supplement manufacturers responded?

As a result of these studies, I expected many manufacturers to drop beta-carotene from their vitamins and substitute plant-derived carotenoids, but it never happened. This is one of the reasons I felt impelled to design my own formula.

Are there any other problems with standard formulas?

Yes. Since beta-carotene gets converted into vitamin A by your body, there is no reason why a person eating a reasonably healthy diet would require any extra vitamin A. The ingestion of extra vitamin A (retinyl palmatate) may be even more risky than the ingestion of supplemental beta-carotene.

There is solid research revealing that supplemental vitamin A induces calcium loss in the urine, contributing to osteoporosis. Too much vitamin A is known to be toxic to the liver, and to cause birth defects. The most common effect of toxic doses of vitamin A in animals is spontaneous fracture.

In humans, excess vitamin A is potentially a problem, even in ranges not normally considered toxic.7 One study found that subjects with a vitamin A intake in the range of 1.5 mg had double the hip fracture rate of those with an intake in the range of .5 mg.8 For every 1 mg increase in vitamin A consumption, hip fracture rate increased by 68 percent. Physicians don’t permit expectant mothers to take more than 5,000 IU’s of vitamin A (retinyl palmatate) because too much vitamin A has been linked to birth defects. These are some of the reasons why—for years—I have recommended supplements with the lowest possible dosage of vitamin A.

A recent study warns of increased mortality risk associated with beta-carotene, vitamin A, and vitamin E supplementation.9

Is vitamin A still included in most formulas?

Yes. In spite of a huge volume of solid information documenting the deleterious effects of vitamin A, it is still impossible to find multiples without it. That is why it was important for me to recommend a multiple that included a wide range of natural, plant-food carotenoids (containing the entire family of carotenoids and not just beta-carotene). It was important for me to create a multiple with no isolated vitamin A.

What about vitamin C? How much is too much?

The current popularity of high-dose vitamin C supplementation is a possible concern. Researchers at the University of California found that men who took 500 mg of vitamin C daily had thickening of their arterial walls 2.5 times greater than men who did not take the supplement.10 Increased arterial thickening increases risk of hypertension and heart disease.

Keep in mind this is only one study. Hundreds of others have shown benefits of supplemental vitamin C for those on the vitamin C deficient diet that the vast majority of Americans eat. Other studies are needed to confirm these findings. However, healthy diets are already rich in vitamin C and contain over 500 mg just from their food. Since people on healthy diets need so little extra, I have included only 100 mg of vitamin C in each of my tablets.

Is excess a problem with any other nutrients?

Nutritional immunologists have shown that nutrient supplementation beyond what can be obtained from the diet is often necessary to optimize immune function, especially in the elderly.11 The downside to supplementation has been the potential risk present from consuming too much of certain nutrients. These include B6, iron, folic acid, vitamin A, and beta-carotene. Iron is an oxidant and can contribute to infection and even increase heart attack risk. It only should be taken as a supplement when a deficiency exists, which is almost always due to blood loss.

Care to avoid consuming too much of certain nutrients is just as important as too little. I frequently find that patients who take an assortment of nutritional supplements consume potentially harmful levels of iron, vitamin B12, and even selenium or zinc. I designed my own multiple with special care to avoid issues from too much of potential risky nutrients, while utilizing quality whole-food, plant sources of those nutrients that offer nutritional insurance. It is unique for what it contains and for what it does not contain.

Because of these features, Dr. Fuhrman’s Gentle Care Formula is an excellent prenatal vitamin as well. It also is designed so an elderly individual with increased vitamin D needs can take three or four a day (instead of two a day) and still not be concerned about the toxicity issues from too much of certain nutrients.

Do vegetarians have any special nutrient needs?

A total vegetarian (vegan) diet is deficient in meeting the nutrient needs of most individuals for vitamin B12. If you choose to follow a vegan diet, it is essential to consume supplemental B12. My multiple supplies the extra B12 and vitamin D that vegan patients almost always need, while still maintaining the vegan purity of the product. This was not easy. I was extremely careful and diligent to make my supplement totally vegan because I have become aware that the vast majority of supplements advertised as vegetarian or vegan are not vegan. For example, the vitamin D in most "so-called" vegan supplements is made from sheep wool fat. Similarly, many supplement ingredients use fish emulsion as a stabilizer. The documentation of ingredient sources and methods of manufacturing was carefully researched.

Can supplements make up for an unhealthful diet?

It is critical to recognize that all dietary supplements are supplements to and not substitutes for a healthful diet. To the extent that they offer some people the confidence to eat less wholesome vegetation, they are hurtful, not helpful. The point to be emphasized is that supplements alone cannot offer optimal protection against disease, and you cannot make an unhealthy diet into a healthy one by consuming supplements.

My Gentle Care supplement is the only one I know that has been designed to be gentle on the digestive tract, non-stimulating, and formulated to be added to a relatively healthy diet. It was not designed to take the place of healthful eating.
