Solaray Bio-Plex Buffered Vitamin C-500 (250 VegCaps)

Gentle, Non-Acidic Immune & Antioxidant Support

Standard ascorbic acid supplements can be harsh on sensitive digestive systems due to their natural acidity. Solaray Bio-Plex Buffered Vitamin C-500 pairs 500 mg of pure vitamin C with natural buffering mineral compounds - calcium carbonate and magnesium oxide - to neutralize acidity and deliver gentle, stomach-friendly daily immune and antioxidant support.   To mirror how vitamin C occurs in whole foods, this formula is fortified with a synergistic plant matrix of lemon bioflavonoids, rutin, hesperidin, acerola cherry, and rose hips to promote bioavailability and capillary integrity without gastrointestinal upset.  

Key Product Highlights

• Stomach-Friendly Buffering: Combines ascorbic acid with alkaline calcium and magnesium to reduce stomach irritation and acid reflux.
• Full-Spectrum Bioflavonoids: Features 100 mg lemon bioflavonoids, 50 mg rutin, and 25 mg hesperidin to maximize cellular antioxidant protection.
• Whole-Food C Support Base: Natural acerola cherry and rose hips supply trace cofactors that assist nutrient utilization.
• Flexible 500 mg Dosing: Convenient single-capsule serving allows you to easily split your intake between morning and evening for sustained tissue saturation.
• Pure & Clean: 100% vegan formula in plant-cellulose capsules; laboratory-tested for potency, purity, and identity.

Why Choose Buffered Vitamin C Over Standard Ascorbic Acid?

1. Reduced Acidity for Digestive Comfort

Pure ascorbic acid carries a low pH (typically between 2.5 and 3.0), which can irritate the gastric lining, trigger heartburn, or cause loose stools when taken in higher amounts or on an empty stomach. By buffering ascorbic acid with calcium carbonate and magnesium oxide, the formula balances gastric pH, allowing the digestive tract to process the nutrient smoothly.  

2. Enhanced Vascular & Antioxidant Synergy

In nature, vitamin C does not exist as an isolated molecule - it is naturally accompanied by polyphenolic compounds known as flavonoids. Solaray Bio-Plex includes:

• Lemon Bioflavonoids (100 mg): Water-soluble plant pigments that help protect cells from oxidative stress.
• Rutin Concentrate (50 mg): A bioflavonoid known for supporting microvascular strength and healthy vein tone.
• Hesperidin Concentrate (25 mg): An antioxidant citrus compound studied for supporting healthy blood flow and endothelial function.

3. Whole-Food Cofactors

Synthetic or isolated vitamins lack the natural cofactors present in botanical sources. Each capsule includes a dedicated 95 mg base of sun-ripened rose hips and acerola cherry, delivering authentic phytochemical balance straight from whole plant sources.

Frequently Asked Questions

What does "buffered" vitamin C mean?

Buffered vitamin C is created by combining acidic ascorbic acid with alkaline mineral salts - specifically calcium carbonate and magnesium oxide in this formula. This reaction neutralizes the acid content, making the supplement significantly gentler on the stomach lining without reducing its biological activity.  

How is Solaray Bio-Plex different from plain ascorbic acid?

Plain ascorbic acid provides pure vitamin C without any digestive buffers or botanical cofactors. Solaray Bio-Plex buffers the acid to prevent digestive discomfort and adds 270 mg of combined citrus bioflavonoids, rutin, hesperidin, acerola, and rose hips to recreate the broad antioxidant profile found in natural foods.  

Why is Bio-Plex offered in a 500 mg dose instead of 1,000 mg?

Because vitamin C is water-soluble, the body absorbs smaller, divided doses more efficiently than a single large megadose. A 500 mg capsule allows you to take one capsule with breakfast and another with dinner, keeping circulating vitamin C levels steadier throughout the day while minimizing excess excretion.  

Can I take this product on an empty stomach?

While buffered vitamin C is formulated to be far gentler than standard ascorbic acid, taking dietary supplements with food or a full glass of water is always recommended to aid nutrient breakdown and optimal absorption.  

Are Solaray Bio-Plex VegCaps suitable for vegetarians and vegans?

Yes. The capsule shell is made from 100% plant-derived vegetable cellulose, and the inactive ingredients (magnesium stearate and acacia) are free of animal products.   As a dietary supplement, take 1 capsule once or twice daily with a meal or a glass of water.
