Brief Introduction

Salicin is a naturally occurring compound found in the bark of several species of trees, primarily North American in origin, that are from the willow, poplar, and aspen families. White willow, from whose Latin name, Salix alba, the term salicin is derived, is the most well known source of this compound, but it is found in a number of other trees, shrubs, and herbaceous plants as well being synthesized commercially. It is a member of the glucoside family of chemicals and is used as an analgesic and antipyretic. Salicin is used as a precursor for the synthesis of salicylic acid and acetylsalicylic acid, commonly known as aspirin.

A colorless, crystalline solid in its pure form, salicin has the chemical formula C13H18O7. Part of its chemical structure is equivalent to the sugar glucose, meaning it is classified as a glucoside. It is soluble, but not strongly so, in water and alcolhol. Salicin has a bitter taste and is a natural analgesic and antipyretic, or fever reducer. In large quantities, it can be toxic, and overdoses may lead to liver and kidney damage. In its raw form, it may be mildly irritating to skin, respiratory organs, and eyes.

Function

1. Salicin is used to ease pain and reduce inflammation.

2. Relieve acute and chronic pain, including headache, back and neck pain, muscle aches, and menstrual cramps; Control arthritis discomforts.

3. Relieve acute and chronic pain.

4. It has the same effect on the body as aspirin without any of the side effects.

5. It is an anti-inflammatory, a fever reducer, an analgesic, an anti-rheumatic, and an astringent. Specifically, it helps to relieve headaches.

Application

1.Anti-inflammatory, anti-rheumatic,

2.Reduce a fever,

3.Use as an analgesic and astringent,

4.Relieve headache,

5.Ease pain caused by rheumatism, arthritis, and carpal tunnel syndrome.

You’ve probably heard this before even at a very young age, “You need to get out in the sun more!” In the ever growing digital world – it becomes less and less likely for people to go out and actually soak up some sun. But besides the social issues that might be caused by staying in doors, there is a very good reason to get outside during the day. Vitamin D.

This is a very vital vitamin to your overall health and is surprisingly important for bodybuilders specifically. Why? Because this vitamin is very different than most – it might actually provide an anabolic effect. So whether it’s through real life sunlight or supplement pill form… watch this new episode of Straight Facts and let Jerry Brainum break down in detail just how important this vitamin is for bodybuilders. Check it out above.

Manufacturing Excellence: The Building Blocks of a Better Supplement
By David Baker

To average people, grapeseed extract is just that—anything pulled from the seeds of grapes.

To scientists in the labs of USANA Health Sciences, grapeseed extract is a complex mixture of organic compounds containing 80–90 percent phenols (also known as proanthocyanidins) and 10–15 percent monomer content.

At least that’s what good grapeseed extract is. If you’ve spent years testing different products, like Dr. Mark Brown, USANA’s director of product chemistry, you know the importance of knowing the good grapeseed extract from the bad.

In his time with USANA, Brown has seen the bad—samples from prospective suppliers that contain less than five percent phenols and no monomers.

“It really makes you wonder, ‘What is grapeseed extract from these people?’” said Brown, an organic chemist by trade. “Usually, what you pay for is what you get.”

The material USANA purchases is on the high end of the price spectrum, but Brown says it’s well worth it because the extract contains greater than 80 percent phenols and has monomer content of about 10 or 15 percent. USANA has been using the product for almost 20 years now, with great results.

“It would be tempting to change and save some money,” Brown said. “But we just don’t work like that.”

The way USANA does work is going above and beyond to make sure the products that bear the company name are the highest-quality nutritional supplements on the market. That starts with purchasing the very best raw materials. But it also means testing every lot of those materials to make sure they’re pure, potent, and worthy of Dr. Wentz’ signature.

Raw material testing starts when shipments enter the building. Quality assurance inspectors check paperwork and perform a visual inspection for shipping damage. From there, a gowned employee, working in a clean room with HEPA filtered air, uses written protocol to collect a representative sample to send to the lab.

Each sample goes through testing for microbiological contamination, like yeast, mold, and bacteria. There are also identification tests to make sure the vitamin B12 you ordered is, in fact, vitamin B12. Potency and physical testing is also done.

Most ingredients then go through specific testing to ensure they meet United States Pharmacopeia (USP) standards for things like purity, solubility, and density. Depending on the product and active ingredient, more tests for pesticides or heavy metals may be done.

“Most people will buy a material, and it will come with a piece of paper that’s called a Certificate of Analysis,” said Dr. John Cuomo, USANA’s executive director of research and development. “They’ll file that Certificate of Analysis away and say, ‘This is what we use. Here’s a piece of paper.’

“We’ve found that sometime you get a piece of paper from companies that actually makes sense, and sometimes they’re just a piece of paper—and worth about as much as a piece of paper.”

The Food and Drug Administration (FDA) guidelines for nutritional supplements hold the manufacturer of a finished product responsible for assuring the material used was the correct material. But that doesn’t mean manufacturers are required to do full testing on every lot of raw materials.

USANA does. Every lot of every raw material is tested. This isn’t the industry standard, but it’s the USANA standard.
