Solaray, Buffered Super Bio Vitamin C
TSTR Super Bio Vitamin C capsules - buffered This Solaray product is based on Two-Stage, Time-Release Technology. This means, that 50 % of the contents is released immediately, and the other half within the next 12 hours. By taking two capsules during mealtime, you can guarantee a continuous flow of Vitamin C for your body. The product contains calciumcarbonate and magnesiumoxide, to build a buffer against the natural acidity of Vitamin C. A capsule contains 500 mg Vitamin C and 250 mg bioflavonoids. Bioflavonoids are water-miscable substances, which are often found in fresh fruits and vegetables, next to Vitamin C. Bioflavonoids increase the absorption of Vitamin C in the body. Which is better? Natural or synthetically produced Vitamin C? The determination whether a substance is natural or synthetic, is not a matter of origin, but a matter of molecular structure. When looking at the molecules of a simple substance like Vitamin C, one could not identify whether it stems from an apple or wheter it is synthetically manufactured from corn. Neither can our bodies identify this. In this case Ascorbic acid is Vitamin C, and Vitamin C is simply Ascorbic acid. It is true that Vitamin C never occurs by itself in nature, but always in connection with bioflavonoids and other active plant substances, which increase absorption of Vitamin C, and which prolong the length of time the vitamin is in the body, and which have some helping qualities of their own (for example protecting blood vessels). Super Bio Vitamin C is produced with the help of highpharmacological processes and it is not extracted from fruits. The pure and natural Vitamin C molecules then are binded to Acerola or other flavonoids, to create an environment which is beneficial for Vitamin C.

I have been using the Solaray formula of "Super Bio C Buffered" now for several years. I believe it is the only formula to supply 70% of Bioflavonoids along with each capsule of ascorbic acid. (Two-caps = 1000 mg of vit-C along with 700 mg or more of bioflavonoids) The research is available on this combination that shows that vit-C will reach more cells and be more functionally useful overall than other vit-C formulas without high-dose flavonoid combinations. Thanks Swanson for making this product available for a great price. I usually purchase the 360 count size, but 250 ct. is pretty good as well.

The Super Bio Vitamin C is easy to take, easy in the stomach and very effective. I take two tablets a day, one each in the morning and evening and remain very healthy. I am 77 years old; have taken the product for many years; and, will continue taking the product for the rest of my life.

Super Bio Vitamin C is one of the best Vitamin C complex I have taken. One after breakfast and one after dinner since it is timed released - just 1,730 mg per capsule. With all the bioflavonoids, also known as vitamin P, which includes rutin and hesperidin that helps maximize the benefits of vitamin C. Bioflavonoids decreases inflammation and allergies; fights viruses, has tumor fighting abilities, good for diabetics and cardiovascular problems, good for the capillaries and veins (varicose), hemorrhoids, bruises, cold sores and hypertensions. Vitamin C is an antioxidant and very essential , so take plenty of vitamin C complex since it's water soluble - leaves the body after several hours.

Vitamin C is one of the constant Supplements I use all the time. I started with the cheapest forms, but later in the time decided to go for supps with higher quality and addded additional nutrition next to the main Vit.C. I have used many forms, but this product somehow seems the best of all. Positives:1.) High concentration of the main nutrition (Vit.C) - 1000 mg per serving+ I can split the intake in 2 - one morning pill and one at nightl2.) Time released - definitely good thing for the absorption and effect.3.) The product has natural Ingredients of Vit.C forms from Rose Hips, Acerola Cherry4.) The product has Bioflavonoid Concentrate (From Lemon) - trust me, not many other products have such5.) Existence of Rutin, Hesperidin, Citrus Pectin - I have not met ... MoreVitamin C is one of the constant Supplements I use all the time.

We love this vitamin C! It absorbs well and helps us when our immune systems are down. I like too that it doesn’t upset my stomach. Great addition to any supplement regimen.
If I feel any little sign of something coming on. Cold Viruses etc. I double up on 2 a day instead of one. It's gone before it settles in. If been taking them for 20 years. And at 70 years old I don't even have a sign of crows feet, my hands look like they did in my 40s. They are well worth taking, and the are inexpensive. The flavonoids are quite like antibiotics only healthier. Highly recommend!
I super duper love Solaray Vitamin C that is why I recommended it to my friends. And this specific bottle i purchased is for that friend of mine. Sadly, i did not noticed the EXPIRY DATE. I purchased this 250caps bottle on April 2021 and the expiry date is August 2021. How can my friend finish 250caps in less 4 months???So, this really served as a lesson for me to ALWAYS ALWAYS ALWAYS check the label first. Check the expiry dates, nutritional content, and pther reviews before check-out.
I've used the Solaray Time Released Vitamin C for years with no problems. It has helped improve my allergies and energy levels.I'm sad to say, it is not the case for the Super Bio Vitamin C. There is an ingredient in this one that doesn't agree with me(burning chest, increased allergies)and also noticed the fatigue is back.
