(C) Other Spartagen XT Ingredients: Vitamins and Minerals

Spartagen XT Side Effects Ingredients ReviewBefore we review further on all the other Spartagen XT ingredients – as indicated, we can see that some “amount of serving” are shown in the unit of “IU” instead of “mg” (milligram).

According to the Dietary Supplement Ingredient Database established by the U.S. National Institutes of Health: “For some vitamins, an International Unit (IU) measures vitamin activity according to biological methods rather than by chemical analysis. The equivalency of one IU differs from substance to substance and is established for each substance by international agreement”.

As such, based on Unit Conversions Table:

  • Vitamin D: 4000 IU = 4000 x 0.025 microgram (µg) = 100 µg = 0.1 mg
  • Vitamin E as d-alpha-tocopherol (natural): 80 IU = 80 x 0.67 milligram (mg) = 53.6 mg


Ingredients #6: Vitamins D / E / B6

  • The upper limit for Vitamin D set by the 2011 Food and Nutrition Board (FNB) is 4,000 IU per day – just as the Spartagen XT’s Vitamin D amount of serving. This is defined as the highest level of daily consumption that causes no side effects in humans when used indefinitely without medical supervision.
    Indeed, while symptoms of toxicity are unlikely at daily intakes below 10,000 IU/day, most reports suggest a toxicity threshold for vitamin D of 10,000 to 40,000 IU/day.

  • The upper limit for Vitamin E set by the Food and Nutrition Board is 1,500 IU (1,000 mg/day), so Spartagen XT’ Vitamin D amount per serving of 80 IU is generally safe without adverse health effects.

  • The upper limit for Vitamin B6 set by the Food and Nutrition Board is 100 mg/day, while clinical trial in 5,442 women aged 42 or older found no effect of vitamin B6 (50 mg/day). As such, the significantly lower Spartagen XT’s Vitamin B6 daily serving of 12 mg is safe.

  • Summary: All the Vitamins in Spartagen XT have amount per serving that are within or significantly lower than the upper limit set by the Food and Nutrition Board, so they are generally safe without bad side effects.


Ingredients #7: Minerals

  • According to Oregon State University, the recommended magnesium intakes in the US is 400-420 mg/day for men and 310-320 mg/day for women, with WebMD reaffirms this claim. While the initial symptom of excess magnesium supplementation is diarrhea, this is not applicable to the significantly lower Magnesium amount of serving at 50 mg in Spartagen XT.

  • Clinical trial conducted by Shiraz University of Medical Sciences in Iran show 100 male patients who received 250 mg/day of Zinc supplement for 6 weeks showed increase in serum level of testosterone, without adverse effects reported. The 30 mg daily of Zinc in Spartagen is well within the dosage used in this clinical study.

  • Summary: The minerals in Spartagen XT have amount per serving that are well within and significantly lower than the recommended daily magnesium intakes by medical experts, and the dosage used in clinical studies with no adverse side effects were reported, so it is safe.


Ingredients #8: Chrysin

Chrysin is an unique bioflavanoid compound which is generally extracted from various types of plants and honey with anti-proliferative effects for cancer prevention and treatment, as indicated by the University of Rome in Italy.

According to WebMD, “Chrysin is POSSIBLY SAFE for most adults when taken by mouth for up to 8 weeks. No adverse effects have been reported.”
