What Do Doctors Say?


Dr. Amy Savagian, MD

Triple Board: Internal, Integrative and Obesity Medicine

“I love the science supporting ProLon, and I love that the science has been published in multiple peer reviewed journals. It allows me to suggest ProLon with confidence. I have used fasting and time restricted eating in my practice for years; ProLon augments this and takes it to the next level.”


Dr. William Hsu, M.D


Former Professor, Havard Medical School 

Former Director of Asian Clinic, Joslin Diabetes Center

Currently Chief Medical Officer, L-Nutra, Inc.

“ProLon carries so many weight, metabolic and cellular benefits that not only do I recommend it, but I decided to join the company’s mission full time as Chief Medical Officer”


Scientifically-proven, fast and healthy weight loss

ProLon has been shown to help people lose an average of 5 pounds of weight, especially effective with belly fat loss, 1.2 inches of waist circumference while preserving lean body mass.


Beyond weight-loss, there is also a wide range of health benefits that includes improving overall health, lowering risks in critical diseases and promoting longevity.

Enjoyable (and it tastes great)

Most other diet plans require a restriction of food, measuring your intake and most likely eating food that doesn’t taste great and you don’t enjoy.


ProLon was created with leading food scientists and chefs to provide delicious food. The no. 1 feedback we have received from our customers is “Very Good Taste!”.


Convenient and easy

The ProLon meals are completed in only 5 days. All the meals you need during the 5 days come within the meal box (one box for each day). You get to eat breakfast, lunch, dinner and even snacks, yet still losing weight.

Grab and go, with minimal disruption in your day. Suits you no matter how busy and hectic your life and work style is.

  • What is collagen?
    Collagen is actually the most abundant protein in the human body, making up approximately 75% of who we are. Collagen is most commonly found in the skin, bones and connective tissue within the body, providing structural support, strength and a degree of elasticity (in combination with elastin). From a beauty and skincare standpoint, collagen is the most critical nutrient in giving your skin its elasticity as well as helping with cell regeneration – replacement and restoration of skin cells. It also reduces wrinkles and fine lines, hydrates your skin as well as prevents sagging skin. Collagen is crucial to your glowing skin. But there’s a catch - collagen production naturally declines with age, which you cannot control. What you can control, however, is your consumption of collagen to replenish it. In fact, studies showed by the time you reach 40, your body will have lost 25% of its collagen production ability. To make up for that and stimulate your body’s natural production, you will need to consume a higher amount of collagen.
  • Why Vida Glow Marine Collagen?
    Our low molecule weight peptide powder form is highly bioavailable, with a high absorption rate above 90%. Bioavailability is an indicator of how easy how easy it is for your body to consume. Most collagen products in the market have an absorption rate of only 20-30%. Pills and tablets instead of powder form deliver even worse. You can therefore do some quick calculation. A premium collagen does cost more, but at the same time it is 3-4 times more effective. More importantly though, why spending on collagen products that do not meet your need and will not reach your goal?
  • How does Vida Glow Marine Collagen compare to other collagen products or collagen consumed through normal diet?
    Surely, you can get collagen through your diet. But the issue is the digestion and absorption ability of collagen through diet into your body are usually much weaker. “Bioavailability” is the term used to describe this, which means how easy it is for your body to take in. The more highly bioavailable, the better. Vida Glow’s marine collagen is broken down into small particle sizes, which results in its high absorption rate. Another issue with absorption through diet is you rarely get enough collagen from your diet. Why is that? Most collagen is found on skin and scales for fish, or around bones for cow or chicken. How often do you eat those parts? Our marine collagen is superior because of two reasons. Marine collagen, compared to other types of collagen, has the most Type 1 collagen, which is the type that contributes to beautiful skin and reduce wrinkles. Not all types of collagen has the same benefits on skin. Another benefit of marine collagen is, compared to other sources of collagen, its absorption effectiveness is 1.5 times higher. More effective absorption, more targeted at your skin health and of course our ultra-high 90% absorption rate into the body. Those are the three reasons why our marine collagen is superior.
  • How does Vida Glow Marine Collagen work?
    Vida Glow Marine Collagen works from within your body to achieve a high absorption. Our collagen is a low molecular weight collagen peptide powder. Once the collagen is absorbed, it is passed through the lining of the stomach and is absorbed by the bloodstream. It is then distributed through blood vessels to the dermis, the deeper layer of the skin, stimulating fibroblast proliferation and increasing the body’s natural production of collagen.
  • What results can I expect from the products? Is it scientifically proven?
    According to scientific research and clinical trials, you can expect to see results in 3 – 4 weeks of taking the product on a daily consecutive level. At this time skin becomes more hydrated, followed by a reduction in fine lines and wrinkles in 6 weeks. By the 9th week you’ll see a noticeable increase in skin elasticity and firmness. Most of our customers have seen changes in 4 – 6 weeks in skin, hair and nails, with some achieving results in as little as 2 weeks. Performance is especially noticeable with higher age group. We recommend taking Vida Glow's marine collagen daily. You will see faster and more effective results. Taking 6 – 9 grams a day (2 – 3 scoops) will accelerate results. If you are taking more than one serving per day, be sure to spread them out, rather than taking all servings at once, this ensures maximum absorption. You can also see more researches validating such findingson collagen products from the National Institute of Health website -
  • How to include the collagen into my day?
    Mix it in your morning coffee or tea or include it in your favourite food or drink. Our marine collagen powder blend very well into foods such as porridge, yoghurt, soup or drinks such as smoothies, shakes, juices or water and is also heat stable. You will see faster and more effective results when taking the marine collagen daily.
  • Our commitment to only safe and clean sources
    Vida Glow's marine collagen is sustainably sourced French collagen extracted from the scales of ocean fish. We use the scales as it is the best source of nutrients and collagen protein. Each new batch of our marine collagen undergoes stringent testing to ensure it is free of heavy metals, contaminants and other toxins prior to being made available to customers. We do not mix in any low quality collagen from shellfish or jellyfish as some other products do. Our marine collagen is pure, high-quality ocean fish collagen. All our products are manufactured and shipped from Europe.
