Recommended dietary allowance (RDA)
There is no RDA. Ensure you discuss supplementation with your Clicks pharmacist or your doctor before taking it.
According to research, those who want to improve their athletic performance should combine 1.2-1.5g/kg of whey protein with strength/resistance training for six to ten weeks.
To combat HIV/AIDS-related weight loss, these are the recommended dosages: 8.4-84g per day, or 2.4g/kg per day in a high-kilojoule formula, or 42-84g per day in a glutamine-enriched formula.
Not enough is known about safe dosages for women during pregnancy or breast-feeding, so rather avoid its use.
If you have a milk allergy or are lactose intolerant, rather don’t use whey protein. If you’re a diabetic, you may experience changes in blood sugar if you take whey protein.

Ensure you discuss dietary supplementation with your Clicks pharmacist to avoid the potential for side effects and adverse interactions with medications. For example, whey protein can decrease the effectiveness of the Parkinson’s disease drug, levodopa.
