Review on OASIS #80254 Vita Drops-Pure C for Guinea Pig: Essential Nutrition in a 2-Ounce Package (Packaging may vary) by Stacey Veeramachaneni

I don't put it in the water, they need fresh water. Instead I put 2 drops directly in his mouth followed by a small bunch of grapes. After several such actions, he had an idea, and now he will try to take the bottle with his mouth while you prepare it! So, even if you don't like it at first, bite into a small piece of your favorite candy, like grapes or pineapple - just not too much, you can become diabetic, it's just for the taste and the reward. He now takes drops without grapes and seems to enjoy them. I tried them. They taste like chewable vitamin C that we give to kids. Absorption will be easier if you eat a piece of fruit or vegetable immediately after the drops. As mentioned, I make a grape slice and then a bunch of cilantro. (Or whatever they like.) My guinea had a very slight runny nose. He gets a lot of healthy food, but he doesn't like peppers and oranges have too much sugar. If he gets 2 drops a day now, it has stopped and won't come back. I don't think it's being claimed to be fake or anything. It's just a different batch and needs to be shaken before use. They stay fresh in the bottle but begin to break down when they hit the water, becoming ineffective after 24 hours. Therefore, it should be thrown into the mouth or placed on a treat to eat immediately. The proof of this is her health. The runny nose is gone and has not returned. I will continue to use it and recommend it to everyone. He had already eaten stabilized vitamin C foods plus fresh foods and it still made a big difference.
