Prescribed For LifeRiboflavin 5 Phosphate Powder, Vegan Vitamin B2 Supplement Powder, Gluten Free, Non GMO, Soy Free, Kosher, Natural Vitamins for Hair, Skin and Nails (2oz / 56g)

These powders are definitely the way to go - absorbed by your body so much better. I'll just keep on doing it this way!!

Mix it with other vitamins in my son's water/lemonade mixture.A tiny little goes a long way. Bitter tasting, but even my son drinks it diluted.Difficult to mix with water. Is very yellow on the fingers.

How many grams of this powder is one serving? It doesn't tell you. It also comes from China, so I'm skeptical of the quality.

Serving 100mg / 567 serving per 2 ounce bag.My personal opinion is this is a great product but firstly want to mentionthat it a bit tedious to use.> It's bitter and needs used in smoothies but surprisingly isn't bad in plain water.It doesn't mix easy with a spoon, but quickly with frother.> It's bright yellow gets on everything it touches, but rinses off well, except fabric / etc.> Leaves fingers and tongue a bit yellow.> Doesn't include a measuring scoop.My interest is for it's antioxidants support that can reduce oxidative stress in the bodyincluding the eyes which supports better vision.> And because of that support, it's thought Riboflavin may help prevent cataracts>>> It's known that a Riboflavin deficiency may lead to cataracts.This is a new product to me. I'm a fan of Riboflavin but mot familiar with Riboflavin 5-PhosphateAfter some research, it appears that Riboflavin 5-Phosphate is the bio-active / tissue ready formof Riboflavin and is more soluble and easier / more digestible than Riboflavin.> This is an essential component of two majors co-enzymes, Flavin mononucleotide (FMN)(AKA) Riboflavin 5-Phosphate and Flavin adenine>>> FMN is a stronger oxidizing agent than NAD (Nicotinamide adenine dinucleotide (NAD) )> This is the principle form that riboflavin is found in cells and tissue but it requiresmore energy for the body to produce.> Another reason to add a bit of this to your diet.> Best absorbed when taken between meals.Comes in a black bag to keep from light as Riboflavin is destroyed by light.However - not by heat.Although the RDA of Riboflavin for adults is 1.1mg - 1.3mg it's considered safe in higher doses.EG: commonly found in 25 mg, 50 mg, and 100 mg tablets / capsules.(If this is more than your system needs the body will eliminate the excess)

First powdered supplement I bought that did not include a measuring scoop. Even if you already have a mg scale it is a hassle (approx. accuracy with scoop would be good enough for my purposes).
