Answer 2

Answer:

2) Vitamins ❤️

Explanation:

Our body does not create vitamins(except some) . So if you don’t get the ones you need through your diet, you may want to consider a supplement as an alternative.

Vitamins are organic compounds which have to be obtained from the diet, because -

➡️An organism does not have the enzymes necessary to synthesize them.

➡️An organism cannot produce them in sufficient quantities.

Humans cannot synthesize vitamins such as -

▫️A (Retinol) ,

▫️B1 (Thiamine),

▫️B2 (Riboflavin),

▫️B5 (Pantothenic acid),

▫️B6 (pyridoxine),

▫️B7 (Biotin),

▫️B9 (Folate),

▫️B12 (Cobalamin),

▫️E (Tocopherol)

▫️K (Phyloquinone)

But humans are able to synthesize some vitamins

such as-

▫️B3 (Niacin),

▫️K (Phylloquinone)

▫️D (Calciferol)
