Thorne Buffered Vitamin C Powder 231 g
Description
Taking high amounts of vitamin C can be a challenge for individuals who have sensitive or compromised digestive systems. For these individuals, Thorne Research has developed Buffered C Powder. Each scoop supplies the same pure, crystalline vitamin C found in Thorne Research's Pure Ascorbic Acid, along with a blend of calcium, magnesium, and potassium mineral ascorbates that serve as a buffer, allowing sensitive individuals to take large amounts of vitamin C with ease and comfort. In addition to 2,350 mg of vitamin C in each scoop, Buffered C Powder provides 350 mg each of calcium and magnesium and 99 mg of potassium.
Recommended Dose (Adults): Mix 1/2 to 1 scoop with water or juice daily or as recommended by a health-care practitioner.
Warnings: Do not take two (2) hours prior to or until four (4) hours after taking other medications. Where impaired renal function exists, the use of potassium supplements should be monitored closely. The use of potassium supplements with potassium-sparing diuretics (spironolactone, triamterene, amiloride) may lead to hyperkalemia. This product is contraindicated in an individual with a history of hypersensitivity to any of its ingredients. If pregnant, consult your health-care practitioner before using this product. Vitamin C can cause diarrhea in some individuals in large doses, which can vary from person to person. This resolves when the dosage is reduced. Do not use if security seal inside the cap is broken. Store tightly sealed in a cool, dry place.

Nice fresh and clean.
Scent: Lemon
I use this for general cleaning, smells fresh, and picks up dirt. I also like it for my acrylic bath tub to remove soap build up no scratching.

When you need some real cleaning power.
Scent: Lemon
Be careful of this stuff. It is very powerful. But wow, does it clean. It can cool rust off of many items. Smell is overpowering. Price is terrible but what else is new? It does not foam unless it comes into contact with something reactive. I put mine in a squeeze bottle for better application.
