  • Vitamin C: What does it really mean for your skin?


    With temperatures hotter than ever this summer, exposure to the harmful effects of the sun can be unavoidable. While it’s easy to forget the daily routine of slathering on sunscreen, damage to the skin can be done in as little as 20 minutes of ultraviolet light.

    What we typically see as signs of aging can be attributed to sun damage throughout the years. Elastin and collagen, two proteins in connective tissue responsible maintaining elasticity and shape, eventually break down under excessive UV rays. This causes the skin to wrinkle and sag, and may even delay the time it takes for cuts and wounds to heal.

    Sunscreen: more harm than good?

    Researchers have suggested that cases of skin cancer would shrink by 72% if children frequently wore sunscreen until the age of 18. A lack of protection can cause more than just a few age spots and freckles; a decrease in the skin’s immune function may lead to cancerous or benign lesions, discoloration and bruising. Since most of these issues are not present right away, some people work to prevent sun damage before it ever occurs.

    Picking the right sunscreen in and of itself can be a challenge, as many brands are packed with chemicals that can do more harm than good. Ingredients like oxybenzone have been associated with skin allergies and abnormal hormone activity, able to penetrate the skin after repeat application. After testing nearly 1,000 brand-name sunscreens, the Environmental Working Group (EWG) revealed that almost 4 out of every 5 products either failed in sufficiently protecting the skin or contained chemical hazards.

    Ascorbic acid to the rescue


    So, what can we do to protect ourselves in our day-to-day? Many people choose natural, homemade alternatives. This is where Ascorbic Acid (a specific form of Vitamin C) truly shines, because it offers an effective shield against the sun without the unnecessary and harmful chemicals that mass-produced sunscreens carry. Many health gurus on the Internet have taken to creating their own serums and sprays, combining Ascorbic Acid with other beneficial ingredients such as rose water, a solution known for its anti-inflammatory and anti-bacterial properties.

    Studies on Ascorbic Acid have revealed that both topical and oral supplementation may reverse the signs of aging due to sun exposure. It does so by lightening dark spots (hyperpigmentation), producing collagen and fighting against photodamage. It may also assist with skin inflammation, reducing effects such as lesions and wrinkles. Ascorbic Acid also happens to be an antioxidant, meaning that it serves to protect the body against free radicals that would otherwise cause harm to healthy cells.

    It’s your turn

    Understandably, everyone is different. Those with fairer skin tend burn faster and more frequently, while people with darker and tanned complexions may incorrectly believe that they can skimp on the sun protection. Countless individuals have taken the future of their health into their own hands, swearing by the do-it-yourself (DIY) approach to supplements, serums, creams and recipes. Most importantly, always be sure to do your research and act responsibly; before you head outside, grab a hat and stay hydrated!

    Crystalized Ascorbic Acid is available in bulk powder and individual capsules here.

  • Are there dangerous additives lurking in your capsules?


    As more people take charge on their own health, capsules have become a quick and effective way to consume vitamins and other nutritional supplements. Preferred over tablets for their faster dissolution rate, capsules can reduce stomach irritation and protect sensitive ingredients, allowing anyone to customize a mix that is tasteless, odorless and easy to swallow.

    It’s not all that unusual to assume that when purchasing a supplement, you receive just that: the supplement in its pure, active form. While we wish this was true, a quick glance on the back of the average nutritional label tells a different story. Not familiar with Polyethylene Glycol or Titanium Dioxide? You’re not alone.


    In today’s market, countless supplements are laden with artificial flavorings, dyes, fillers, anti-caking agents and binders. To save money and mass-produce their supplements, big manufacturers pump up their products with additives and chemicals. This reduces quality and potency, forcing the consumer to buy more product. Not only are many of these chemicals unregulated by the FDA—several can actually affect bodily absorption, compromising the active ingredient’s purity and bioavailability.

    What are additives and fillers to look out for?


    Magnesium Stearate

    Magnesium Stearate is often included in mass-produced capsules to stop powder from caking and is estimated to be found in about 90% of vitamin supplements. Because the body’s digestive enzymes are forced to break down this agent first, the absorption of vital nutrients is delayed. Stearic Acid is also commonly sourced from hydrogenated cottonseed oil, which is believed to contain more pesticide residue than any other commercial oil. Unfortunately, there’s never any guarantee that supplements containing Magnesium Stearate are free of harmful contaminants.

    Titanium Dioxide

    Another additive frequently included in capsuled supplements is Titanium Dioxide, which is not found naturally in any food. Used as a colorant, this metal pigment contains nanomaterials, or ultrafine particles able to penetrate healthy cells. Studies are currently examining whether Titanium Dioxide is a carcinogen to humans, as excessive exposure has been linked to cancer, allergic reactions and immunotoxicity. Aside from supplements and food, it is also added to cosmetics and sunscreen.


    There are currently no regulations on the amount of Silica allowed in supplements. It is often used in powdered foods and as insect repellent; long-term use has been connected to cases of respiratory and kidney damage.


    Be assertive about your health

    Always do your research and purchase capsuled supplements from trusted companies that believe in an unaltered, natural product. At the Bulksupplements manufacturing and distribution facility, we use manual and semi-auto filling processes for all of our capsules, ensuring that no additives, anti-caking agents or other chemicals compromise purity. Our gelatin and vegetarian capsules contain no preservatives or allergens and are non-GMO, promising simple and effective supplement delivery.

  • Whey Protein Isolate 90% vs. Whey Protein Concentrate 80%: What is the Difference?

    plastic measuring scoop of white powder (whey protein) against grunge wood background

    Whey protein powders are not a new fad and have been around for quite some time. Most people associate them with losing weight or body building because protein is a primary nutrient that aids in both of these processes. Additionally, since protein is so important to the body, whey protein is found in many products like ice cream, bread, and even baby formulas as it allows the protein content to increase and is so easily digestible.

    When it comes to choosing what type of whey protein is the best, whey protein is divided into two categories: whey protein concentrate and whey protein isolate.  It is important to note that there is a third called whey protein hydrolysate but it is simply a purer form of whey isolate. So, are concentrate and isolate different?  And, if so, what is the difference?

    Whey Protein Concentrate vs. Isolate


    The answer to the aforementioned question is yes: they are different. But before we discuss the differences, let’s start at the beginning and discuss what whey protein is.

    Whey protein is a mix of globular proteins (unstructured protein) found in milk.  Not only does it help with weight loss and building muscle, but it also aids in preventing heart disease and other conditions like diabetes and bone loss that occurs as people age.

    Whey Concentrate. Whey protein concentrate contains byproducts other than just protein. It still has small amounts of lactose and even milk fat in it, which keeps it from being simply protein. Most whey protein concentrate contains about 80% protein, with the other 20% as carbohydrates and fat (not the bad kind). This form of concentrate is much better when used for its health benefits such as improving the immune system and maintaining a healthy diet. Because it does contain trace amounts of lactose, those who are lactose intolerant should avoid it for obvious reasons.

    Whey Isolate. Whey protein isolate is almost pure protein with only 10% at most being byproducts like fat. It is basically whey protein concentrate that undergoes further processing and purifying to contain more protein than concentrate. Whey protein is used by those trying to lose weight or build muscle. This form is used in many meal replacement programs because of its high protein content which curbs the appetite and aids in quicker weight loss. For body builders, it increases muscle growth after resistance training. In terms of its advantages, it is a better option for those who are more interested in building muscle and/or losing weight as well as those who are lactose intolerant.

    Both Are Beneficial to the Body

    When deciding between the two types, the main things to take into consideration are cost and purpose. If money is no object and weight loss or building muscle is the goal, paying up for whey protein isolate might be a better option especially if there is an issue with lactose intolerance. But if the purpose of drinking shakes with whey protein is simply improving health, spending the extra money is not worth it and whey protein concentrate is the whey (ha – get it?) to go. No matter the choice between whey protein concentrate and isolate, both are beneficial to the body.
