What’s the scientific relevance of vitamin C amongst lead-exposed infertile males? In comparison with controls, lead battery trade employees given 1,000 mg of vitamin C each workday for 3 months skilled “a big enhance in sperm motility and sperm depend, in addition to lower in irregular sperm,” and “a big discount within the incidence of sperm DNA fragmentation,” that’s, broken sperm DNA. Okay, however the supreme endpoint can be bouncing child girls and boys. Enter this extraordinary little research from the College of Texas from greater than 30 years in the past.

Twenty-seven males with fertile wives had been attempting to have children for years to no avail. Twenty of them got 1,000 mg of vitamin C a day for 2 months, and seven acted as controls and didn’t get any vitamin C. The researchers adopted up on the finish of the 60 days. By then, each single one of many wives of every of the 20 males who had gotten the vitamin C had grew to become pregnant—20 out of 20! After years of frustration, growth: 100-percent pregnant. What’s extra, not a single one of many wives of males within the management group acquired pregnant. Hardly ever does one see these sorts of black-and-white leads to the medical literature for any intervention.

Is the vitamin C reducing the oxidative stress from the lead, or is it truly reducing the stage of lead? Certain, antioxidant supplementation can have antioxidant results, however it might fail to really decrease lead ranges within the blood. Now, this was in a body of workers who have been respiration lead day in and time out, and the best way vitamin C may go is by merely blocking the “intestinal absorption of lead.” An earlier research confirmed vitamin C supplementation apparently reduce lead ranges by a 3rd inside six months, however that was with a whopping dose of two g with added zinc. One other small research discovered the identical 30 p.c drop with simply 500 mg a day, no zinc, and in just one month. However neither of these research had a management group of topics who didn’t take something, so we don’t know if their ranges would have fallen anyway.

Equally, there’s an nearly too-good-to-be-true research on the function of vitamin C in scavenging lead toxicity from “biosystems,” by which they meant kids. They acquired 250 to 500 mg a day of vitamin C for a number of months, and shaved hair samples each month noticed as much as a 69 p.c decline in lead ranges. Researchers repeated it in two different small teams of children and noticed the identical wonderful type of drops in each single little one. However perhaps lead ranges have been simply dropping all through the entire group throughout that point? With out measuring lead ranges in a management group of children not taking vitamin C, we will’t make certain.

As I illustrate from 3:17 in my video Yellow Bell Peppers for Male Infertility and Lead Poisoning?, with eight weeks of vitamin C, lead ranges dropped within the blood and rose within the urine. One might conclude that the vitamin C was pulling lead out of the physique, however the identical factor occurred within the placebo group: Blood ranges dropped, and urine ranges rose. So, it had nothing to do with the vitamin C in any respect. That’s why it’s at all times necessary to have a management group.

The identical applies with research that appeared to indicate no profit. For instance, 36 battery manufacturing employees have been studied. Every was given vitamin C, but there was no change of their lead ranges. However, perhaps their co-workers suffered a giant enhance in lead ranges throughout that very same time interval, and the vitamin C was truly profitable in conserving the topics’ ranges from rising. You don’t know and not using a management group.

That’s why research like “The consequences of vitamin C supplementation on blood and hair ranges of cadmium, lead, and mercury” are so necessary. Vitamin C versus an identical-looking sugar tablet placebo. The end result? The vitamin C failed to assist, which actually put a damper on enthusiasm for utilizing vitamin C for lead poisoning till a now-famous research was printed in 1999 that confirmed that vitamin C supplementation might result in a lower in blood ranges. As you’ll be able to see at 4:32 in my video, after 4 weeks of taking a placebo, not a lot change occurred in blood lead ranges within the management group, which is what we’d anticipate. In distinction, the vitamin C group began out at about the identical blood lead stage because the management group, however inside one week of taking 1,000 mg of vitamin C a day, lead ranges dropped 81 p.c. So, supplementation of vitamin C “could present a cost-effective and handy methodology of lowering blood-lead ranges, probably by lowering the intestinal absorption of lead.”

The urine lead ranges didn’t change, so it’s not as if the topics have been excreting extra lead of their urine to carry down their blood ranges. Nonetheless, many of the lead in our blood is within the crimson blood cells, that are recycled within the liver and discharged by way of the bile into the intestine the place the lead might simply get reabsorbed—except, maybe, you’ve acquired quite a lot of vitamin C in there to dam the re-absorption. However 1,000 mg is quite a lot of vitamin C. Would one thing like 200 mg, which is nearly how a lot vitamin C you’d get in an orange and a cup of broccoli or strawberries, work? The researchers examined that, too. The 200 mg group began out the identical because the management and the 1,000 mg group, however blood lead ranges didn’t actually budge. Bummer! So, 1,000 mg appeared to work, however 200 mg didn’t. Isn’t 1,000 mg of vitamin C a bit unnatural, although? The RDA is simply 60 mg. Nicely, truly, we could have advanced for hundreds of thousands of years getting nearer to 600 mg a day—ten occasions the present RDA—as a result of we have been consuming so many fruits and greens. Okay, however might you attain 1,000 mg of vitamin C with out having to take capsules? Sure! That’s the quantity of vitamin C, for instance, that may be present in three yellow bell peppers.
